Container Planting Instructions for Trees

protect the graft union

PLEASE REMEMBER – The graft union is the most fragile point of a young newly grafted tree. However, as the tree ages, the graft union becomes the strongest part of the trunk.  Trees should NEVER be lifted or moved above that point – always be very careful to handle the tree below the graft union and support the main trunk when transporting the tree from nursery container to a new container. 

It is helpful to have an assistant when transplanting your tree!

step 1 - container planting

Select a large, sturdy container (20 gallons or larger).

Drill several 3/4-inch drainage holes in the bottom.

Place spun poly type weed mat (may be purchased at Isle of Sky Nursery) over the holes.

step 2 - container planting

Fill the container part way with a good quality organic potting soil such as Fox Farm’s Coco-Loco which is sold at Isle of Sky Nursery. Mix in one-half of the Grow Mix. The soil level in the container should be high enough to elevate the tree to the top of the container. Remember, the soil with settle over time.

STEP 3 - Container planting

Whack the back of a shovel against the outside of the container to loosen the roots inside the pot.

STEP 4 - Container planting

Gently remove the tree from the nursery pot and place it upright in the prepared container.

DO NOT handle the tree above the graft union.

STEP 5 - container planting

Finish filling the remaining space with your organic potting mix and lightly work the remaining half of the Grow Mix into the surface.

Stake the tree with one or two good wooden or heavy bamboo stakes to support your tree from the winds.

Water thoroughly before top dressing with 2 inches of partially rotten pine needles.

NOTE: The pine needle mulch is the top layer and the remaining Grow Mix is added to the lower layer as per the illustration arrows.
