While it is important to know what the signs of tree disease and illness are, you should also know how to determine if your tree is growing healthy. When you know this, you will be able to tell if there is something wrong with your tree if or everything is fine. There are a number of signs that you can look for which indicate healthy growth.
Only One Central Leader
Most trees will have one leader which will turn into the trunk of the tree. This adds stability and strength to the tree allowing it to grow straight. If there is more than one leader, there could be a problem with your tree. However, there are some species of tree that have more than one leader and you need to be aware of this.
There are some fruit trees such as cherry, plum, and peach which will have more than one leader and should have split. There are some trees that have several trunks, but there should be one leader for each. Bonsai and topiary formed trees will generally not have a single leader based on the form being used.
Evidence Of Yearly Growth
Yearly growth is a good indicator of good health and you need to check this. You can easily see if growth has occurred by looking at the branches of the tree. You will also be able to determine how much growth has taken place by looking that the buds on the branches.
To use the buds to look at growth, you will need to take note of the distance between the new buds and last year’s buds. The old buds will be evident as scars on the branch. The amount of growth you should be seeing will vary depending on the tree species as some trees grow faster than others.
No Bare Patches
Trees that have bare patches in their leaves are not healthy and need to be looked at. You can check your evergreen trees all year to see if there are any bare patches. However, you will need to wait for the spring and summer to check deciduous trees. There are many reasons why your tree might have bare patches and not all of them will be poor health.
If animals are eating the leaves, this could result in a bare patch where the animals are able to reach. This is not a problem, but you will need to be careful and check that the animals are not harming the branches. Pesticide and insect damage will also cause bare patches and this needs to be looked into because it can affect the health of the tree.
Proper Leaf Color, Shape And Size
A good indicator of tree health is the leaves and if your tree has leaves which are the right color, shape, and size, it will be healthy. The color of the leaves will vary depending on the season and unless you have a tree with variegated or yellow leaves, you should only worry when leaves change color outside of the correct season.
