How to Deal with Chlorosis in Trees in Knoxville, TN

Pro Tree of Knoxville works as Knoxville’s premium tree removal company, providing expert arboriculture knowledge and care. Read more to learn the signs and causes of tree chlorosis.

What Is Chlorosis in Trees?

Chlorosis causes the leaves on a tree or shrub to lose their ability to produce chlorophyll. This condition can be very dangerous to the plant’s health since leaves without chlorophyll cannot create carbohydrates through photosynthesis. Essentially, chlorosis starves the tree of energy, causing it to die slowly.

Chlorosis comes from an iron deficiency. In the same way humans can get iron-deficiency anemia, plants develop chlorosis when they do not have enough iron to help them create chlorophyll. This lack of iron can come from soil with too high of a pH or that doesn’t have enough nutrients.

Identifying Chlorosis in Trees

As mentioned, one of the best ways to identify chlorosis is by looking at the condition of the tree’s leaves. A chlorotic tree’s leaves will have dark green, almost healthy-looking veins, but the remaining flesh of the leaf will appear yellowish. In more severe cases, the leaf’s condition can mimic nitrogen deficiency.

Nitrogen deficiency occurs when you put too much high-carbon mulch or nutrients, like sawdust, in the soil. The organisms in the soil will consume nearby nitrogen to break down the carbon, not leaving enough for the plants. A tree with nitrogen deficiency will have complete leaf yellowing, including the veins.

Although chlorosis in trees develops on new growth first, nitrogen deficiency appears on old growth first. Advanced chlorosis will completely lighten new leaves and start affecting older ones, making the two conditions difficult to differentiate.

How to Save Your Trees From Chlorosis

If you suspect you’re dealing with chlorotic trees, confirm your suspicion by calling a trustworthy laboratory for soil testing. After identifying the issue, do not trim or prune any leaves or branches. Although trimming and pruning can help a plant grow well, it would harm a chlorotic plant, which already cannot produce enough energy to heal.

Instead, treating chlorosis in trees requires you to reintroduce iron into the soil or onto the plants themselves. Arborists use trunk injections, foliage sprays, and soil treatments. If you put too much or too little iron back into the tree, it can recover too slowly or fail to recover at all.
