Chlorosis is the yellowing of leaves due to a lack of chlorophyll. More specifically, iron chlorosis is the lack of chlorophyll caused by an iron deficiency. Leaves that are yellow due to the lack of chlorophyll are not providing the energy a normal healthy leaf would. Reduced energy production results in tree stress, which makes the tree more susceptible to abiotic injury, as well as insects and disease.
Iron chlorosis can be confused with:
Fig 4. Pin oak with iron chlorosis and severe dieback. It is likely that other factors along with iron chlorosis are causing dieback in this tree.
Fig 3. A chloritic maple tree. New growth on the outside of the tree is yellow while older growth near the trunk is green.
Iron chlorosis is not fully understood and many factors can cause or influence the deficiency.
There are several ways Wellnitz Tree Care can treat iron chlorosis. There is usually no long term solution for iron chlorosis, however problems like girdling roots and soil compaction can be corrected by air spading. Wellnitz Tree Care can do soil amendments if soil pH is too high, however if high levels of calcium carbonate are present, this will be ineffective. Soil amendments will generally have to be done every several years to keep the soil balanced. We also offer iron injections into the trunk of the tree (fig 6) which are good for up to three years.
