Organo-Lawn are experts in tree care for iron chlorosis treatment and prevention in the Boulder and Fort Collins Colorado areas.
When a tree is suffering from chlorsis and it is not responding to our deep root tree fertilization treatments we must perform an IV to get the tree functioning again. Organo-Lawn uses a special Tree IV treatment that will introduce a special form of iron into the tree and force the tree into producing chlorophyll again.
The way the Tree IV system works is similar to an IV used in hospitals, except it is into a tree. First we drill 1/4" small holes in the tree’s trunk near the base of the tree. These holes do not cause irreparable damage to the tree. We then attach injection plugs into the holes and place the injection needles into the tree’s trunk. Using air pressure we inject the tree with a liquid mix of chelated iron and magnesium. The tree has no choice but to accept the liquid concentrate of iron and magnesium that is injected into the xylem layer of the tree.The tree's recovery will be proportional to the level of the severity of Chlorosis at the time of treatment. The response time to the IV treatment can be very rapid or can be very slow depending on the overall health of the tree. Noticeable greening and improved vitality will often be obvious within the growing season and sometimes within weeks of the application. We tend to see faster improvement with trees that are suffering from minor chlorosis (Stage 3-5). Severely chlorotic trees (Stages 6-10), larger trees or older trees will show a slower response and a second application might be necessary.
With older trees we often see results the following year which means the tree will not turn green the year of the application; however, the following year the leaves will typically bud out green and typically stay green.
Important: Tree IV is not a permanent fix to the problem. The main problem is the soil around the tree is dead and needs to be returned to a healthy and living state. To do this changes will need to be made with the watering and here are some instructions on how to create a living soil.
Organo-Lawn uses a special tree IV kit to force the tree to uptake the iron treatment. Boulder and Fort Collins area trees tend to live in clay-like soils which causes iron chlorosis.
Important Note: Oak trees tend to recover from chlorosis much faster and easier than maple trees.
