Do I Plant Above the Graft of the Tree?

When it comes to planting trees, one of the most common questions people have is where they should plant the tree in relation to the graft. This is because the graft is an important indicator of the tree's health and performance, and planting too high or too low can have serious consequences. Here's what you need to know about properly planting a tree above the graft.

Understanding the Graft

The graft is the point where the rootstock and the scion of a tree are joined together. This is typically done in order to produce a hybrid or to transfer traits from one tree to another. The rootstock is the lower part of the tree and provides the root system, while the scion is the upper part and provides the canopy and fruit. The graft union is the area where the two parts are joined together.

The Importance of Planting Above the Graft

When you plant a tree, it's important to plant it above the graft. This is because the rootstock and the scion have different characteristics and needs. If the tree is planted too deep, the rootstock will begin to grow and take over the scion, which can result in poor performance and even death. On the other hand, if the tree is planted too high, the scion may not be properly anchored in the ground and may not receive the nutrients it needs from the rootstock.

How to Plant a Tree Above the Graft

To properly plant a tree above the graft, start by digging a hole that is deep enough to accommodate the entire root system. The hole should be wider than the roots to allow for proper growth and development. Make sure the graft union is above the soil level, but not more than an inch above. This will ensure that the scion is properly anchored in the ground and is receiving the necessary nutrients from the rootstock.

Once the tree is in the hole, backfill the soil and gently tamp it down to remove any air pockets. Water the tree thoroughly and add a layer of mulch around the base to help retain moisture and control weeds. Be sure to continue to water the tree regularly for the first few months to help it establish a healthy root system.

The Bottom Line

When it comes to planting a tree, it's important to plant it above the graft in order to ensure proper growth and performance. By understanding the graft, its importance, and how to properly plant a tree, you can help ensure that your tree thrives for years to come.
