Roots to Shoots Just as important as having a proper pruning schedule in place, are other aspects of tree care that should not be overlooked.These include watering, installing a ‘tree well’ and more.
Roots will often take advantage of the air and moisture found just beneath the surface of a sidewalk (or driveway) and expand to the point that they may damage them. A great way to prevent this is to plant your tree 2-3 meters from the sidewalk, and/or install a root barrier that will re-direct the roots away from the sidewalk Root barriers can come in several shapes and sizes and can either be purchased or constructed at home. When installing a root barrier or
WRAP THE TAPE MEASURE AROUNDTHE TRUNK OF THE TREE 1.4 METERS ABOVE THE GROUND
working with a tree’s roots please be sure that you are outside of the critical root zone. The critical root zone of a tree can be calculated quickly and once identiﬁed it is a great way to help protect your tree; all you need is a tape measure, and maybe a calculator.
STEP 1 - Wrap the tape measure around the tree trunk at approximately 1.4
metres above the ground.This number is the circumference (example, 50cm).
--- 95cm ---
--- 95cm ---
STEP 2 - Divide the circumference by 3.14 (50cm/3.14 = 15.9cm), this number is the diameter (15.9cm).
STEP 3 - Multiply the diameter by 6 (15.9cm*6 = 95cm), this number describes the length of the critical root zone (95cm) out from our example tree trunk.
CRITICAL ROOT ZONE OF EXAMPLE TREE
* All root pruning, root barriers and other work that could impact the roots of this example tree will need to be at least 95cm away from the tree trunk. Once you have identiﬁed your tree’s critical root zone please work outside of it to ensure the health and safety of the tree.
Good soil is the foundation for a healthy tree. It should be able to drain well, yet still hold onto water and nutrients.You learn a lot about the soil you have by picking up a small handful and rolling it between your ﬁngers. Does it... Firmly stick together like play-dough?Your soil doesn’t drain well. Fall apart like sand?Your soil won’t hold onto water and nutrients. Loosely ball up like brown sugar?You soil holds water and nutrients for just the right amount of time!
IF YOUR SOIL DOESN’T LOOK IDEAL, CONSIDER TAKING A SAMPLE INTO A LOCAL NURSERY FOR ANALYSIS AND ADVICE BEFORE TRYING ANY AMENDMENTS OF YOUR OWN.
IT IS IMPORTANT TO WATER YOUR TREES, WITH A SLOW TRICKLE FOR AT LEAST 15 MINUTES, TWICE A WEEK DURING THE WARMER MONTHS (MAY TO SEPTEMBER). 092011
