Monterey Iron Tree Treats Iron Supplement For Trees 1-0-0, manufactured by Monterey, is a highly effective iron supplement capsule that lessens yellowing (iron chlorosis) and other micronutrient deficiencies in trees.
The 1-0-0 pk formula contains nitrogen and iron to aid in overall tree health. Nitrogen is essential for promoting healthy tree growth and helps in photosynthesis, the process in which plants use sunlight, water, and carbon dioxide to transform into chemical energy for survival. Iron is a critical micronutrient for chlorophyll production and is responsible for green pigmentation in tree leaves.
Monterey Iron Tree Treats Iron Supplement For Trees 1-0-0 is a fast-acting fertilizer that ensures iron and other micronutrients are readily available for the tree, allowing for efficient uptake and long-lasting green and vibrant trees.
Tools Needed
You will need a tape measure to measure your tree and a drill to create holes in the ground.
How to Use
- Step 1: Simply measure the tree diameter 12 inches above the ground. For tree diameters over 2 feet tall, create 10 holes and place 1 capsule in each hole. For tree diameters 12-18 inches, make 8 holes and place 1 capsule in each hole. For tree diameters 6-9 inches, create 4 holes and place 1 capsule in each hole. For tree diameters 5 inches, make 2 holes and set 1 capsule in each hole.
- Step 2: Drill a small 3/8-inch hole 1-1/2 inches deep for each capsule. To avoid weakening the tree, drill holes uniformly around it at different heights.
- Step 3: Place capsules into each hole. Grafting wax may be used to seal the holes. After 2-3 weeks, you may apply again to areas not greened up.
Where to Use
Monterey Iron Tree Treats Iron Supplement For Trees 1-0-0 can be used in the soil around trees.
When to Use
Treatments are most effective from the time of leaf-out until the end of July. The most successful results occur early in the growing season.

We recommend watering with a slow-release tree watering bag or watering with no more 1 inch of irrigation once per week." |
