IN THE GARDEN How to transplant a tree It!s getting late in the season, but if you must, here!s how... M any smallholders greatly value the trees that grow on their plots, so if there's a tree in the way of their extension, driveway or proposed swimming pool, they are not likely to pull out the chainsaw. Rather they will look at the option of transplanting it, as long as it is in good health and shape, it won't need serious hauling to be lifted out, and it's not an alien invasive species. Some say that winter is the ideal time to move a tree, but spring is not too late for a deciduous tree, before it begins to leaf out, but after the threat of frost. Late summer is usually a good time to move evergreens. A suitable spot to receive the transplant will preferably have soil of a similar type, with similar drainage and sun exposure for the tree to thrive. Dig the hole to receive the transplant first. Make the hole square, which will encourage the roots to spread into the surrounding soil. Estimate how large the root system will be when you dig it out. Allow for the root system to go into the ground to the same depth it was originally at. If the soil is extremely hard or com- pacted, you will want to dig the hole much larger to loosen the soil around the perimeter to make it easier for the roots to spread when they begin to grow outward. Place a generous amount of compost at the bottom of the hole to ensure that the tree receives good nourishment during its re-establishment phase. Most trees also need proper drainage and soil pH between 5.5 and 6.5 in order to thrive, so test the soil before planting and amend as needed. Mark the tree trunk with a dab of paint on the north side, so that you will place it in its new spot facing the same way that it was origi- nally. This minimises the stress on the tree while it is settling into its new position. Now excavate a trench around the tree, cutting the roots as you work. Leave as much soil and root mass intact that you feel you can manage to move, as this will help the tree to settle quicker. Depending on the size and species of the tree, the trench around it should be about 50 cm deep before you begin to excavate under the bowl of root mass. When you can no longer reach under the tree, by which time it should be wobbly, fasten a rope around the trunk at about a metre height or higher, depending on the sturdiness of the trunk. If you use a chain, wrap a cloth around it to prevent it from damaging the bark. Make sure that the rope is long enough so that, when it is attached to whatever vehicle you are using to tow the tree, it won't topple onto the vehicle. Attach the rope to the vehicle and pull the tree over slowly. As it bends chop away the remaining roots. Place skids, eg, two or three gum poles, under the bowl of earth and root and slide the root mass up the poles out of the hole and onto a sheet of corrugated iron. Attach the rope to the corrugated iron and use it as a sled to move the tree to its new location. Position the bowl of roots as close as possible to the new hole, in such a way that you can push it into the hole and raise the tree, taking care to have the paint mark facing north. 43 www.sasmallholder.co.za
