Tree IV - FAQs

Q. Does the drilling of the hole into the tree cause significant damage to the tree?
A. No; we only drill small holes into the tree and the tree will repair the damage from the holes typically within 1-2 months.

Q. Do you remove the plugs from the tree?
A. No; we leave the plugs in the tree, but we do remove the needles. We recommend that you leave the plugs, because an open hole leaves the tree susceptible to infection.

Q. Can you reuse the plugs from the tree if a second application is required?
A. No; the tree has callused over the plugs and they will no longer be effective. If we have to retreat the tree we will drill into the tree again.

Q. How long does it take for the tree to green up?
A. That depends on the tree and the severity of the chlorosis. Trees that will recover quickly from 1-3 months include: minor chlorotic trees, actively growing trees, younger trees, and trees that are taking up water quickly. Trees that will recover slowly from 3 months to 1 year include: severely chlorotic trees, older trees, and trees that are in very dry areas.

Q. How long does it take for the IV treatment to be performed?
A. It takes anywhere from 5 minutes to 8 hours depending on the tree and how fast it uptakes the nutrients. In cases where the tree is absorbing very slowly, we may leave the equipment hooked up and return the next day to retrieve it.

Q. What will my tree look like after the application?
A. That depends on the tree. Some trees will just slowly perk up and the leaves will turn green. With some trees all the leaves will turn brown and fall off and then new green leaves will begin to grow. Older trees may not change much after the application; however, the following year the new growth will bud as green growth and stay that way. The results really depend on how severity of the chlorosis.

Q. What trees tend to develop Chlorosis?
A. Typically the fall color trees including: Birch, Maple, Oaks, and Aspens. In the Oak family the red oaks tend to be more susceptible to chlorosis. In the Maple family the red maples and silver maples tend to be the most susceptible.

Q. What will happen if I don’t treat my tree for Chlorosis?
A. The tree will become more and more chlorotic and eventually die. This typically can take between 3-10 years to kill a tree.

Q. When is the best time to have the tree IV performed.
A. We can treat any time of year, however, we have found that June and September are good months to treat for chlorosis. June is a good time because the tree still has color in the leaves and the injection might be useful for the summer. September is preferred because at this time of year the tree is pushing nutrients into the foliage for winter storage. We have tested timing for this application and have found that September is the best month to treat for chlorosis.

Q. What if the treatment does not work on my tree, is it guaranteed?
A. Yes; we guarantee the treatment to work so if it does not work we will re-apply the product free of charge. We do have to wait until the following year to treat the tree a second time because the tree might show the signs of recovery the following spring. We guarantee the treatment to improve the stage of chlorosis, but it may take several treatments to get back to full health. We require spring and fall deep root fertilizations in addition to the IV in order for the guarantee to be valid.

Q. How do I know if the tree is dying and not worth treating?
A. Our applicator will advise against treatment if the tree is not going to live even with treatment.

Q. Should I treat my tree with the Tree IV even if it is not chlorotic?
A. We do not recommend treatment with the tree IV for non-chlorotic trees. It is too invasive; we recommend deep root tree fertilization with iron instead.

Q. After the tree recovers and is no longer chlorotic what should I do to prevent future chlorosis?
A. It is strongly recommended that you have 2 applications of deep root tree fertilizer each year with extra iron. This will help prevent the tree from becoming chlorotic again.

Q. Is it possible for the tree to become chlorotic again if I do the deep root tree fertilization two times per year?
A. Yes; the problem that causes chlorosis is in the soil. Trees that live in areas with a high pH have difficulty absorbing nutrients like iron and magnesium. Deep root tree fertilization helps reduce chlorosis but we cannot guarantee against a future problem.

Q. If my tree becomes chlorotic again, typically how often does this occur?
A. If a tree is treated using the Tree IV and becomes healthy again it might take 3-5 years for the tree to become chlorotic again. Or, the tree might not become chlorotic again. Trees are living organisms and each tree responds differently to the same treatment.

Q. Is there a tree that is too small to treat?
A. We are not sure; it is not recommended to treat trees smaller than 2” diameter breast height. We cannot guarantee that smaller trees will not die from the treatments, however, we have treated smaller trees and have had good results. Typically with smaller trees, all the leaves will be burned and fall off within the first week after application. The tree will then re-grow the foliage in about a month and the new foliage will be green. Once again we cannot guarantee that a tree of this size will live through a treatment.
