Your Guide to Enjoyable Gardening and Easy-Care Landscapes ® I’m not a birder by any stretch. I like birds, I’ve enjoyed creating a friendly habitat for birds, and I spend lots of hours pointing my camera at birds in my own yard. I consider the weekly trips to the car wash a small price to pay for their company. But after years of doing these things, I’m still not very good at identifying them by sound, or even often by sight. Oh, I know the usual suspects, and I’ve learned a few new ones in the last decade. But when an LBJ ( little brown job) stops by the feeder or bubbler, it’s a sparrow to me, or it’s pinkish hue might suggest a male finch, but that’s often as specific as my mind allows.

Margy Terpstra is a birder. Maybe not the kind who travels the world chasing exotic species (though she’s done some of that), but the kind who, along with her husband Dan, have created a bird haven (thus the name of her blog, HummerHavenUnLtd. com) right in their own Kirkwood back yard, and in doing so, have brought the birds to them! By the thousands! She knows the birds and she knows what they want and need. Food, water and shelter. Her above-mentioned blog is a platform for her to share the beautiful photographs she captures of birds who visit and often take up residence at what she calls Shady Oaks Sanctuary.
My bubbler water feature frequently coaxes birds from high in the canopy down to a phtographable distance.
She also imparts what she knows about the birds and their needs. I asked Margy to share some of that information—and beautiful photos—with our readers on page 20. The spring migration is underway, so if you want to learn more about birds, now’s the perfect time.
For those with more traditional gardening styles, there’s still plenty to consume in this issue. Steffie Littlefield reflects on why she loves vegetable gardening so, and offers tips to grow that love in others on page 10. Turn the page, and Scott Woodbury gives us reason to give thanks for the relatively harsh winter we’ve endured. It will result, he believes, in even more abundant native blooms this spring! Elsewhere in these pages, you can learn about mulch, epiphytes, products to garden sustainably, and more. Meanwhile, I’m looking forward to those spring blooms and the spring birds April promises. I know you are, too!
Plants that glow in the dark are probably not on a bird’s list of must haves. But human plant lovers sometimes have different desires than feathered plant lovers. Abby Lapides acknowledges a gardener’s love of things new and unusual with some examples of the latest “mad scientist” gifts to the gardening world on page 4. Most are not as space-agey as the Petunia ‘Firefly’ glow-in-the-dark example alluded to above, but still offer different twists than one might normally expect from its species. Canna lilies with flowers of gold speckled in orange? Yep! A blue mandevilla? Got it! These and a few more species’ surprises await for the something-new gardeners out there.

lants of unusual colors, unheard of sizes, and even one that glows! No, we’re not on an alien planet. Through clever breeding we get to witness annuals unlike anything we’ve seen before.
Need a little light at night? Try ‘Firefly’ petunia, the firstever glow in the dark petunia! A beautiful white flowering petunia by day, Firefly transforms at night with its mesmerizing luminescence, emanating a soft moon-like glow. You’ll wonder at the magic of the plant, but Firefly petunia is the result of cuttingedge biotechnology. Scientists spliced the petunia’s DNA with that of bioluminescent mushrooms, creating an amazing wonder.
‘Bluephoria’ Mandevilla delights with stunning color breakthrough. Coral-pink buds open to periwinkle flowers. The compact form can be left unstaked, allowing it to flow over
the edge of containers and hanging baskets, or it can be trained onto a small trellis for more height. This first-ever blue-hued mandevilla is sure to turn heads.
You can pretend you’re on a tropical island with the major award winner ‘Waikiki’ elephant ears, Colocasia. It creates a fascinating spectacle as its ginormous leaves unfurl and change color. The leaves begin green with a purple back. As the leaves mature, they develop white center markings with pink that spreads into the veins, radiating outward like a starburst. ‘Waikiki’ Elephant Ears’ long stems can grow 3.5′ tall. Plants mature into attractive clumps 3-5′ wide. Cooler weather brings out more coloration. Use it in pots alone or as a showy accent.
Large bicolor spikes create a stunning showcase on ‘Berry Sparkler’ Angelonia. Pink flowers with purple zebra stripes bloom on extra-large spikes all summer long. Angelonia is prized for its strong flower show and ability to thrive in even the hottest of summers. Part of the Guardian Angel series, which is known for having the largest flower spikes of any Angelonia.
‘Golden Leopard’ canna brings the allure of the Caribbean right to your garden with its majestic, banana-like leaves and vibrant flowers. Yellow flowers with dramatic orange flecks look like an exotic animal print. Striking foliage contrasts with the flowers, making them an eye-catching option for mixed containers or inground plantings.
Enjoy months of periwinkle blue flowers on ‘Monarch Magic’ floss flower, Ageratum. Forming into an almost perfect dome of flowers that are magnets to Monarch butterflies, your garden will come alive with the flapping wings of butterflies. Drought and heat tolerant, Monarch Magic is easy to grow and perfect for containers, hanging baskets, or in the ground. Not to be confused with the aggressive native Ageratum houstonianum, this nonspreading plant behaves itself and dies out once temperatures drop below freezing.
The first bicolor trailing lantana, ‘PassionFruit’ enchants with plump pink, yellow, and orange flowers all summer until frost. Perfect for hanging baskets, mixed containers or on its own, ‘PassionFruit’ attracts butterflies and hummingbirds. Though the flowers look delicate, this annual is as tough as nails, thriving in St. Louis summer heat and humidity without breaking a sweat.
When designing mixed containers or adding bold accents in the garden, think about adding a few of these exciting new plants.

Epiphytes are fascinating plants that grow on other plants or objects without taking nutrients from their hosts. Found in diverse environments ranging from tropical rainforests to arid regions, epiphytes have unique adaptations that allow them to thrive independently. Orchids, tillandsias (air plants), and staghorn ferns are three popular types of epiphytes cultivated for their beauty, intriguing growth habits and for being pet friendly. Here, we’ll explore what epiphytes are and how to care for these remarkable plants.
Epiphytes derive moisture and nutrients from the air, rain and debris around them. Unlike parasitic plants, they do not harm their hosts. Their adaptations include specialized roots, waterstoring structures and the ability to photosynthesize efficiently. These characteristics make them excellent choices for indoor and outdoor gardening, especially for those seeking unique, low-
maintenance plants. Epiphytes, like many other houseplants, thrive in temperatures ranging from 60-70 °F. Be on the lookout for areas that are drafty like windows or near forced air vents, which impacts their ability to take in the needed humidity. Next, we’ll look at the general care for these 3 epiphytic classes of plants.
Orchids, particularly species like Phalaenopsis and Dendrobium, are some of the most popular epiphytes. These plants are admired for their striking flowers and exotic appeal.
Light: Orchids thrive in bright, indirect light. Direct sunlight can scorch their leaves, so place them near an east or north-facing window or use sheer curtains to diffuse light.
Watering: Water orchids once the bark mix is nearly dry.
Overwatering is a common mistake, as orchids are prone to root rot. Ensure pots have proper drainage to prevent water from pooling. Steer clear of using ice cubes to water as it gives their roots frostbite.
Humidity: Orchids prefer high humidity levels (50-70%). Use a humidifier, pebble tray or mist the leaves regularly to maintain optimal conditions.
Fertilization: Feed orchids with a balanced orchid fertilizer every 2-4 weeks during their growing season. Reduce feeding during dormancy, i.e. the winter season.
Repotting: Repot orchids every 1-2 years using a bark-based medium to ensure proper aeration for their roots.
Tillandsias are versatile and low-maintenance epiphytes that can be mounted on various surfaces, such as driftwood or rocks. Or even find a unique pot to display them in. Their sculptural forms make them a favorite among plant enthusiasts.
Light: Provide bright, indirect light for air plants. Avoid placing them in direct sunlight, which can cause scorched leaves and dehydration.
Watering: Submerge tillandsias in water for 20-30 minutes once a week. In dry conditions, mist them lightly between soakings. Shake off excess water to prevent rot.
Air Circulation: Good airflow is essential for tillandsias. Avoid placing them in enclosed or stagnant areas.
Fertilization: Use a diluted air plant fertilizer monthly to promote healthy growth and flowering.
Staghorn ferns are named for their antler-like fronds, which add a dramatic touch to any space. These ferns are often mounted on wooden plaques or grown in hanging baskets.
Light: Bright, indirect light is ideal for staghorn ferns. Too much direct sunlight can scorch their fronds.
Watering: Water weekly by soaking the entire plant, including the root ball and fronds. Allow it to dry slightly between waterings.
Humidity: High humidity is crucial for staghorn ferns. Mist them

frequently or use a humidifier to replicate their natural environment.
Feeding: Apply a balanced, watersoluble fertilizer every 4-6 weeks during the growing season. Avoid overfertilizing, as it can damage the plant.
Mounting Care: If mounted, ensure the base (often sphagnum moss or coconut coir) stays moist but not waterlogged.
Pet friendly epiphytes like orchids, tillandsias and staghorn ferns bring a touch of natural elegance to any space. By understanding their unique needs—such as proper light, watering, humidity and feeding—you can create an environment where these plants will thrive. With care and attention, your epiphytes will reward you with lush growth and, in many cases, stunning blooms or foliage that elevate your home’s aesthetic. Swing by your local garden center to check these out. Happy Gardening!

Everyone knows I’m a huge vegetable gardening addict. From the time I could walk I helped and played in my darling Grandmother’s vegetable garden. It was a classic kitchen garden layout of low raised beds bordered by bricks that were laid on a diagonal, to point their corner up, with crushed stone pathways. It was bordered by white ranch-style fencing with chicken wire attached at the bottom. The perimeter beds were filled with brambles at the back and cutting flowers along the front with a huge white bent wood arbor over the gate for some of her favorite heirloom roses. Strawberries lined the borders of some of the beds. As children it was our magical space and along the way we ate lots of juicy red strawberries. Along the east side of the garden were wooden raised beds with slanted tops of glass, cold frames, for starting seedlings and cuttings for the vegetable garden and her many flower beds. Here we tended small marigold plants that we later helped plant along the walk to the kitchen. All summer we were to pinch the dead flowers off to keep the plants clean and tidy. Every weekend we visited we would “ooh and aah” over the colorful fresh vegetables we helped to harvest. On Sundays we went with her to visit her elderly friends and take them baskets and crates of asparagus, potatoes, tomatoes, squash, peppers, flowers and herbs. It brought so much joy to everyone’s life; who wouldn’t want to make this a life-time hobby and share it with children and grandchildren. As I embarked on my quest to create vegetable and flower gardens big enough to share with friends and family, I ran into the same challenges my grandmother might have, which are also those that my gardening friends and clients share. How do we make our gardens efficient and not so much work that we dread going into the garden. I have followed her example of doing raised beds but even to the next level of filling them with clean compost and worm castings. My aisles are also paved with crushed stone to eliminate mowing, and I have studied companion planting theories to make an environment to promote healthy plants and avoid common pests. Through trial and error I have discovered vegetables that are easy and reliable and have eliminated those that are only marginally successful. I have
also managed to cultivate a lot of plants that are perennial and therefore do not need to be replanted every season.
Here is my list of ‘must haves’ in the vegetable garden:
Broccoli—planted with Kale under row cover to keep the pests away and keep them shaded.
Lettuces—several varieties planted in succession to harvest into late June/early July.
Parsnips—which I let go to seed the first year and now they are perennial in my garden.
Celery—Red Venture is my favorite, it is fairly winter hardy and easy to sow from seed, few pests.
French Sorrel—perennial, producing wonderful lemony salad greens even in summer.
Sugar snap peas—planted on a fence with Beets at the base, then plant cucumbers for summer.
Okra—pretty flowers, love the young pods for soups, dried stalks for fall decorating.
Tomatillos—they reseed in my garden and are prolific in the heat of the summer.
Malbar Spinach—they reseed on two towers adding height, a delicious summer green for salads.
Yard long beans—a hearty reseeder that produces right through the heat of summer into fall.
Asparagus—perennial, providing years of harvest over two months in spring.
Sweet Potatoes—plant the plants in May and harvest bushels of sweet potatoes to eat all winter.
Bush Beans—Direct sow in late April; green, yellow wax, purple, colorful and good for the soil.
Tomatoes—plant many varieties since not all will do well every year, plant near asparagus.
Cherry Tomatoes—lots of different colors planted with tee-pees close for children to harvest with toy buckets.
Peppers—Hot, sweet and mild, red yellow, green and orange, pest resistant, so versatile.
Horseradish—perennial, prolific, harvest in November, pest control plant for potatoes.
Spaghetti squash-easy to grow and has a great shelf life.
Patty Pan Squash—the most insect resistant of the summer squash, fast growing.
Eggplant—loves the heat, loves to be grown near beans for the nitrogen fixing attributes.
Italian Fennel—reseeds, love to cook the greens, sauté the base and the seeds for soups.
Leeks—buy the plants, very pest resistant, plant early, harvest in the fall for Thanksgiving.
Onions—plant the plants for large onions, cut flowers to keep them from producing seeds.
Shallots/Egyptian Onions—these have hearty bulbs on stalks that make them perennial and the greens are great for cut green onions all summer.
Herbs—dill, basil, cilantro –reseed themselves.
thyme, oregano,, sage, lavender, chives—perennial parsley,—biannual rosemay, bay, taken inside for winter in a pot mint in a cute container like an old wheel barrel or metal cooking pot
pineapple sage for color, teas and salsa
Those who tend even a small, one-bed vegetable garden or a container on a deck, not only harvest fresh, healthy food but also experience the satisfaction of a successful gardening project and the joy of sharing their plentiful crops.

Wood poppy and Virginia bluebells brighten a spring woodland garden in a residential neighborhood.
One of my customers recently expressed anxiety about the long, cold winter now behind us. She was worried that plants suffered as much as we top-dwellers did. But snow covering the ground and freezing temperatures for weeks on end shouldn’t be a cause for concern. Decades ago this was more common. Every winter I used to skate on ponds. Now it’s rare to find a cold spell long enough to safely freeze a pond. But this year it did. The freezing-cold stretches lasted for many weeks and so did the snow. It’s all as it should be, I told my customer—ground frozen, garden blanketed in snow, and plant roots happily tucked away for winter.
Over the years, I’ve noticed that immediately after steady cold winters, when the ground is frozen solid longer, blooms of spring wildflowers are better. Displays of wood poppies, violets, wild geraniums, wild hyacinth, and Virginia bluebells are all more intense, prolific, and with more stems and flowers pushing up through the ground in April. This spring should be like that.

Jacob’s ladder, blue-eyed Mary and Virginia bluebells, seem to burst with even more spring energy after a cold, snowy winter.
Plant vigor and bloom displays have to do with at least two things. First, the stress derived from the previous year’s excess drought or rainfall, which can set plants back. Last year was a bit rainier than normal. Second, when soil is wet in winter, but

matter into the soil. Two steps forward, one step back. Sadly, it doesn’t generate as many spring blooms. This is a normal process, a cycle of life: flourish, wither, die, then back to flourish all over again. Each generation builds on the next. It’s how plants transform poor compacted soil into healthy organic topsoil. Slowly, over time, this transformation happens. I see it especially in older neighborhoods where the disturbances of new home construction have had time to heal.
Topsoil around a 100-year-old house (with plants) is softer, deeper, and has more organic matter. How do I know this?
When I start a new project, I sink a shovel into the ground and take a look. Soil around old houses is easier to dig and tends to be full of worms and other soil-churning invertebrates. At the microscopic level, these soils are full of bacteria and fungi. These organisms—these little garden buddies—decompose dead plant matter into organic matter (humus) as deep as roots will grow and give soil healthy structure
and tiny pockets of air. A perfect environment for plants to thrive. The soil around old houses also drains water better than around a 20-year-old house. To my chagrin, I can’t sink a shovel to the hilt at my new house. I always hit compacted clay near the surface. I also have drainage problems. On the bright side, it will be a 100-year-old house at some point, and the future owners will perhaps appreciate the gardens and trees we are planting now, and the little garden buddies that will inevitably follow. I choose to dream on!
That said, I’ve seen topsoil transformation happen over a much shorter period of time. It took a mere decade or two for the soil at the grounds of Alberici Corporation in St. Louis to transform from tortured bulldozer clay to decent prairie earth. For the first five years, compass plant and big bluestem were scrawny seedlings. Fifteen years later, they became towering beanstalks reaching up tall, the proof that organic matter deposits were building, year after year, deeper into the ground, and perhaps as deep as the plants are tall (8 to 10 feet). I once dug a compass plant up at Shaw Nature Reserve that I had started from seed. It had a thick root that sank 8 feet deep into the old field soil. It started from a seed, tossed out of a bucket on the ground 15 years earlier. The power plants have to help themselves is remarkable. They survive and thrive in community with other organisms that help them along. Plants are resilient to disruption—they bounce back in spite of the occasional downturn. So, this season, don’t be anxious; don’t let the long, cold winter we have had get the better of you. Spring will be a little brighter, a little fuller, and taste a little sweeter than the new normal.

Mulch has been a staple in landscapes for decades. It enhances the beauty of flowerbeds and gardens with its fresh colors and textures, but its true value goes beyond aesthetics. Mulch plays a vital role in soil health by enriching it over time. As natural wood fibers break down, they mimic nature’s slow decomposition process, gradually improving soil structure and fertility. This ongoing transformation creates a better growing environment, making mulch an investment in the long-term success of any greenspace.
The Many Benefits of Mulch
Mulch provides numerous advantages for gardens, landscapes, and urban green spaces. One of its most significant benefits is moisture retention. By reducing evaporation, mulch helps keep soil hydrated for longer periods, decreasing the need for frequent watering. It also acts as a natural weed suppressant, blocking sunlight from reaching weed seeds and preventing them from sprouting. Unlike chemical herbicides, mulch offers an eco-friendly way to keep garden beds neat and weed-free.
Beyond weed control and moisture conservation, mulch serves as a protective layer that regulates soil temperature. In hot summer months, it keeps soil cool and shields plant roots from extreme heat. During winter, it acts as an insulator, preventing frost from penetrating deep into the soil. This temperature regulation helps create a stable environment for plant roots, reducing stress and
promoting healthier growth.
Mulch also plays a crucial role in preventing soil erosion and compaction. Heavy rain and strong winds can wash away topsoil, depleting essential nutrients. Mulch helps anchor the soil, reducing runoff and preserving its structure. Over time, as mulch decomposes, it feeds beneficial microorganisms and introduces organic matter into the soil, further improving its texture and fertility.
Not all mulch is created equal, and selecting the right type depends on your landscape needs. One key distinction is between double-ground and triple-ground wood mulch. Double-ground mulch consists of larger, coarser wood pieces that decompose more slowly. This makes it ideal for long-term coverage around trees, shrubs, and large garden beds, as it provides lasting benefits with minimal maintenance. It is particularly useful in high-traffic areas or commercial landscapes where durability is essential.
Triple-ground mulch, on the other hand, is finely shredded and breaks down more quickly. This makes it an excellent choice for flowerbeds, vegetable gardens, and areas where soil enrichment is a priority. Because it decomposes at a faster rate, it integrates with the soil more efficiently, providing nutrients and improving its overall quality.
Bark mulch, which comes in various forms such as shredded or nugget-style, is another popular option. Shredded bark mulch interlocks to create a dense, moisture-retaining layer, making it an
excellent choice for sloped areas where erosion control is needed. Bark nuggets, while slower to decompose, allow for better air circulation and are often used around trees and large shrubs.
Applying mulch correctly is just as important as selecting the right type. A common mistake is creating a “mulch volcano,” where mulch is piled high against the base of a tree. This practice can trap moisture against the trunk, leading to rot, disease, and pest infestations. Instead, mulch should be applied in a doughnut shape, keeping a few inches of space around the trunk to promote healthy root growth.
The recommended mulch depth varies depending on the area being covered. A layer of two to three inches is ideal for most garden beds, providing adequate moisture retention and weed suppression without suffocating plant roots. For larger landscape areas or pathways, a thicker layer of three inches or more may be beneficial.
Mulch should be replenished regularly, as organic varieties naturally break down over time. While finely ground mulch may need to be refreshed annually, coarser mulches can last multiple years before requiring replacement. By maintaining a consistent mulch layer, gardeners can ensure long-term soil health and landscape vitality. Mulching is one of the simplest yet most impactful ways to enhance a garden or landscape. From conserving moisture and regulating temperature to enriching soil and preventing erosion, mulch offers a range of benefits that go far beyond its decorative appeal. Choosing the right type of mulch—whether double-ground for longevity or triple-ground for quick soil integration—ensures that plants receive the best possible support. With proper application and regular replenishment, mulch becomes an essential tool for maintaining vibrant, healthy greenspaces for years to come.

April is prime time for spring migration! Ducks, geese and shorebirds are well on their way to their northern breeding grounds from their southern winter homes. Sixty percent of North American songbirds use the Mississippi Flyway, which includes the St. Louis area. These migratory songbirds drop in overnight, rest a while, then sing their unique songs along with resident birds as the dawn chorus fills the air. They will spend 1-3 days foraging and feeding in good stopover habitat. Warblers, vireos, kinglets and other small songbirds are attracted to yards with chickadees and titmice because their presence indicates habitat with plenty of available food. Studies show that migratory birds return to these same stopovers, having encoded the locations onto maps in their DNA. Wow, isn’t that an amazing survival tool?
Did you know that birdsong is the primary indicator of habitats that support our health, too? So, everything we do to restore habitat is also good for us!
The very best way to ensure our native birds will find the insect food they need to breed and raise their young is to provide native habitat. Aim for 70% native plant diversity with keystone plants such as oaks, cherries and sugar maples. Add smaller natives to the understory such as hazelnuts, viburnums, and serviceberries. Find a spot for plants like golden currant, buttonbush, and cliff goldenrod. Be sure to leave the leaves in the fall, and add native wildflowers, ground covers, grasses and ferns. This layered diversity supports life—ours and birds as well as butterflies, moths, bees and other beneficial insects. Another vital ingredient to add is water, because all birds need fresh water for drinking

and bathing.
So, now that the birds have come, how does one begin to identify these colorful beauties that are singing their hearts out? One can learn from the many resources available, though I freely admit after decades of birding, there’s always more to learn about birds. Jump in and accept that it may sometimes be overwhelming and frustrating, but also loads of fun, especially with a like-minded friend. Go on a bird walk with mentors from the St. Louis Audubon Society. Check this link for the latest information: https://stlouisaudubon.org/bird-walks/
Pick up a free booklet entitled, Enjoying Missouri’s Birds, available at Missouri Department of Conservation offices, like Powder Valley Conservation Nature Center in Kirkwood, MO. It contains charts which show the months of the year that birds are here in their preferred habitats and how abundant or rare they are. Some of these birds do stay in Missouri to breed. To download an annotated checklist of Missouri’s 442 species of birds, use this link from the Missouri Birding Society: https://mobirds.org/ Birds/MOChecklist.aspx
Download a free app called Merlin from The Cornell Lab to help you identify the birds you are hearing. As you use it, it lights up with the name of the bird. It is not always 100% correct, so do

your best to confirm what you hear with what you see. Need a pair of binoculars? Take a look at this site with options for every budget: https://www.audubon.org/gear/binocular-guide
Two of my favorite paperback field guides are Peterson’s Field Guide to Eastern Birds and the National Geographic Society Field Guide to the Birds of Eastern North America.
For a mobile field guide, Audubon, Sibley and iBird Pro work well. At some point, you may want to use eBird by The Cornell Lab to make checklists of what you see with the ability to add photographs for documentation.
Happy Spring Birding!
