How to save Wrapping in place versus bringing plants inside is a personal decision based on a number of factors. Not everyone has the space to bring their entire garden inside their home. If the area inside is not heated, care should be taken that temperatures will remain in the upper 30s at least. If this is not possible, then keeping the plants outside may be more practical. Longer, colder temperatures will be more damaging than a few hours at 30 degrees, so duration of freezing temperatures should be considered. If the forecast predicts only a short period of time at or just below freezing, protect the most delicate and prized plants. After the freeze, the others may show signs of distress, but they should recover as temperatures warm up. Small fruit trees that are potted may be difficult to move. Some plants, such as sago palms or lilies, are toxic to pets, so caution must be taken. Planning ahead for longer, harder freezes will make the process easier. Bring inside whatever is feasible.
For those plants that must remain outside, have supplies ready. You’ll need blankets, cardboard boxes, and LED or holiday lights, which can all be recycled or repurposed after using. Before wrapping, water each plant heavily. Try to avoid putting blankets directly on plants, especially if precipitation is expected. The weight of a frozen blanket can snap branches or trunks and the ice will cause more damage if directly touching leaves or stems. Instead, try to put a box over the plant to trap warmer air and then cover the box with a blanket. If possible, put a strand of holiday lights or a shop light inside the box to add warmth. Once temperatures are closer to 40 degrees, bring potted plants back outside and uncover wrapped items. If possible, avoid trimming back any damaged areas until springtime. Many years have multiple freezes, so it is best to wait until the full extent of the damage is known. Cultivate SA | 29
