climate resilient trees

Everyone should be planting trees. Having witnessed so many droughts , fires,cyclones,and many other adverse climatic conditions across the globe has put forward a challenge before everyone and now is the time that we should be planting and replacing trees if we can meet two important criteria; select trees that are adapted to survive in our a particular climate and ensure they receive adequate water through their establishment phase.

Most tree health problems begin in the root zone so planting your tree properly is critical to its future value.

Trees are commonly planted too deep triggering a chain of health problems related to a poor root gas exchange. Researchers have discovered that planting a tree as little as one inch too deep may set it up for decades of poor vigor or cause it to die within months.

To plant a tree properly, measure from the top of the root flare to the bottom of the root ball and dig the planting hole no deeper than this measurement.

The root flare is a slight widening at the base of the tree where the buttress roots expand into the soil.  If the root flare isn’t visible, expose it by carefully removing excess soil at the top of the root ball to reveal the top of the anchorage roots. The planting hole should be dug at least twice as wide as the root ball so that when it is backfilled, the loosened soil adjacent to the tree can accommodate lateral root development.

Once the tree is properly placed in the hole on firm soil, any burlap and wire should be removed away from the roots to avoid interfering with their growth. The hole should be backfilled with the soil originally dug out.  Investigations into the value of adding amendments such as compost, fertilizer and growth promoting materials have frequently revealed no enhanced root growth for newly planted trees.

Backfill the hole until it is about one third full, carefully packing this soil around the roots to remove any air pockets that would cause them to dry out.  Continue backfilling in this manner until the hole is filled.

Use any excess soil to create a four inch berm around the edge of the root ball and mulch the area within the berm using wood chips to help retain soil moisture. Your newly planted tree may require eight months or more to become established.

Daily watering during the first week will protect the roots from transplant shock.  Slowly harden off your tree to its environment by watering only as needed by checking the soil moisture with your finger.  If the soil is cool and moist to the touch, it probably does not need water. Do not allow the soil within the root ball to remain fully saturated or become completely dry during the first year.
