TreeHelp Iron Spike

TreeHelp Iron Spikes contain 16% iron sulfate and bring back a lush, green color to trees whose leaves are yellowing out of season from iron deficiency. They are proudly made in the USA.

How do I know my tree needs iron?

If you see leaves turning yellow while the veins stay dark green, your tree may have iron chlorosis and you should treat it with TreeHelp Iron Spikes. Iron is essential for making chlorophyll, which keeps trees and ornamental plants green and lush. When iron is deficient in the soil, iron chlorosis results:

• Leaves turn yellow while the veins remain dark green.
• If the condition continues, leaves may turn white or brown and the tree may die.
• Sometimes the whole tree is affected, sometimes only a few parts.

How do TreeHelp Iron Spikes work?

Placed in the ground around the tree, the spikes release iron and alter the soil pH at the same time, making the iron accessible to the tree. The tree can then make more chlorophyll and the leaves become greener. You can see positive results 30 to 90 days after application, but the full effect normally shows the following growing season.

What trees can benefit?

Most landscape trees and shrubs are affected by iron chlorosis and can benefit from TreeHelp Iron Spikes. These are particularly susceptible:

How many spikes do I need?

Use about 1 spike per 5 inches of trunk circumference (the measurement around the trunk). A medium-sized tree typically needs 5 to 10 spikes. If symptoms are severe, increase the dosage.
