Just a quick note on properly planting a new tree. I’ve seen way too many poorly prepared tree root balls this spring to wait on putting out this post. So many installers (professionals and DIYers) believe that burlap sacks on rootballs should be left on the tree when it is planted. Just the opposite is true — remove that burlap and all the string that is holding it onto the tree.

The string, if left in place, will girdle the tree as it matures. As the tree ages, its trunk will get wider. If the string still wraps around the trunk, the tree will grow over the string. The tree’s transport systems — the part of the tree that transports water up to the leaves and nutrients down to the roots — is just under the bark layer. So, as the tree grows over the string, the string will choke off this system or “girdle” the tree. And, the tree will die.

Also, when planting a new tree, you want to be sure to put the root system below ground and the trunk system above ground. Often a burlap wrap is tied significantly above the point where the trunk enters the soil. So, if you plant your tree in the burlap, odds are you will plant it too deep.

Finally, roots need to be free of the burlap in order to expand into the surrounding soil. This expansion will allow the tree to take root strongly. It will allow the tree to establish itself. If the burlap is left in place, likely the roots will not expand or they will circle in the burlap. Yes, burlap is a natural substance that may decompose over time. However, it may take longer to decompose than it takes for your tree to try to establish itself. And, if the roots start going in circles for years, they likely won’t stop going in circles once the burlap does rot away.

And on staking…really, usually staking isn’t necessary and can ultimately cause a tree to avoid building strong roots that allow it to hold itself up on its own. Stakes can be necessary on very windy sites where the young tree may blow over or used as a training tool for leaning trees. But, more often than not a stake isn’t required. Too, if you are going to stake your tree, use loose ties that are attached to the tree as low as possible. By tieing off low and loose, the tree is allowed to sway and move, which encourages it to root strongly. And, remove stakes after about 6 months and no more than one year. Those ties can also end up girdling your tree over time. And, once established, a tree even in a windy area should be able to support itself stake-free.

So, do yourself a favor and take the burlap off. Take the string off. And plant your tree to a proper depth.
