By far the two biggest mistakes I see when home owners (and some landscape companies) plant a tree is planting too low, and too much mulch. In today’s quick tip I’ll give you my secrets to planting a healthy tree in North Texas.

Mistake 1: Planting tree too low

This simply mistake is the most common one we see and does damage to the tree. It also is the main reason if a tree has been planted for a year or so and never really grown. Most think a tree is supposed to be planted with the root ball flush with the soil level. This results in people planting their trees too deep which makes it hard for your newly planted tree to thrive.

What you should do is plant the tree, so the root flare is flush with the soil level (to get a better idea of the root flare, think about a neck flares into a person’s shoulders. The problem is a lot of growers take the excess dirt from digging the tree out of the ground and pile a layer of that dirt onto the root ball. That means many trees arrive with a two to three inch layer of dirt that needs to be scraped away to export the root flare which most people don’t realize (or miss.)

The reason this is bad for your tree is that this excess dirt rots the bark off of the tree and prevents valuable nutrients from moving from the roots up to the branches. One of the symptoms of a tree that has been planted too deep is if you lean on a tree that has been in the ground a few years and that tree’s trunk rocks easily back and forth in the ground, that tree is slowly rotting.

Mistake 2: Too much mulch (a.k.a. mulch volcanoes!)

This is a case of doing something right, wrong. Mulch is great for plants and trees. The problem is when a person goes overboard piling too much mulch up against the tree trunk. The next time you are out and above, pay attention to the mulch volcanoes in your neighborhood. Most people, including far too many landscape professionals and lawn care workers, make this mistake.

For a tree to thrive nutrients and oxygen pass back and forth in a layer just underneath the bark. A telling example of how important this is for a tree, years ago, when a farmer wanted to kill a tree on their land, they would take their knife and cut through the bark all the way around the tree. This cut effectively cut off the tree’s supply of nutrients. This is called girding a tree and that’s exactly what happen when you plant a tree too deep or pile too much up around the trunk. The bark rots which cuts off the supply of nutrients.

Make no mistake, you need to mulch your new tree (and plants) but the way to do is to leave a gap of about two or three inches away from the trunk of the tree.
