Iron Chlorosis Treatment

Iron Chlorosis Spikes for Trees and Shrubs

Lutz Iron Chlorosis Spikes treat Iron Chlorosis (Yellowing) in Pin Oak, White Oak, Rd Oak, Silver Maple, River Birch, Pines, Crabapple, Sweet Gum, Magnolia, Dogwood, Holly, Poplar, Juniper, Rhododendron, Azalea, and all other acid-loving Trees, Shrubs and Plants.

Iron is necessary for the formation of chlorophyll, which is responsible for the green color in plants and is a source of plant food and energy. When the amount of iron available to plants is inadequate for normal growth, leaves become pale green, yellow or white, eventually brown and die. The newest foliage is most severely affected by iron chlorosis. If not corrected severely affected plants may fail to grow, flower or fruit.

Lutz Iron Spikes are the ideal soil amendment for iron poor plants

Soil pH is most often a factor in Iron Chlorosis. Se we put a full 4.8% Sulfur in our Iron Chlorosis Spike, which creates an environment in the feeding area that frees up the iron, which is in a form readily available to the plant. The 5% Nitrogen also assists with the uptake of all nutrients, but most importantly the 16% iron sulfate we have in the Iron Chlorosis Spike.

Favorable color responses are often seen the 2nd growing season. Amending iron chlorotic soils is a process, so annual applications are recommended, semi-annual applications if iron deficiency is severe. Greatest color response is seen with the onset of new leaf.


"Just a note to let you know that after about 1 year remarkable improvement in our pin oak (I think, as it was bought as red oak). I tried a lot of 'juices' for about 2-3 years to help this tree out but it only got worse every spring/year and feared it would die. Nursery said there was nothing we could do for it - yea right - but your stuff did the trick. Cant wait to see how it looks next spring. Again thanks for the help."

"Hong Kong Orchid Tree: this tree's leaves got yellower and lost them all. We used Lutz Iron Spikes after talking to Mr. Lutz. He said the new growth would be perfect. Voila!"

Suggested Coverage and Placement of Spikes

Trunk Diameter 4" 6" 8" 10" 12" 15"
Spikes Used* 4 6 8 10 12 15

Measure the diameter of tree trunk 3 feet above ground level. Use one Spike for every inch of diameter. Place Spikes into moist soil, equally spaced around the dripline. (See illustration).

For acid-loving shrubs such as azalea and rhododendron, use one Spike for every 2 foot of plant height, evenly spaced at dripline, never closer than 2 feet (24 inches) from trunk.

Hammer Spikes to ground level using the plastic pounding caps. Remove cap and pound in at least two more inches. Heel the holes closed.

Lutz Iron Tablets treat Iron Chlorosis (Yellowing) in Pin Oak, White Oak, Red, Oak, Silver Maple, River Birch, Pines, Crabapple, Sweet Gum, Magnolia, Dogwood, Holly, Poplar, Juniper, Rhododendron, Azalea and other acid-loving trees, shrubs and plants.

Iron is necessary for the formation of chlorophyll, which is responsible for the green color in plants and is a source of plant food and energy. When the amount of iron available to plants is inadequate for normal growth, leaves become pale green, yellow or white, eventually brown and die. The newest foliage is most severely affected by iron chlorosis. If not corrected severely affected plants may fail to grow, flower or fruit.

As high pH is often a factor in Iron Chlorosis, the 20% elemental sulfur in the Super Iron Chlorosis Tablets creates an environment in the feeding area that frees up iron, and along with the 5% nitrogen, assists in the plant's uptake of the tablets 30% iron. Favorable color responses are normally seen anywhere from 3 – 12 months from time of application, depending on soil structure, the amount of water/rainfall applied to the area and the type of plant being treated. Most favorable color response seen in new leaf.


Directions For Ironing Your Plants

Trees

  • Use 4 tablets per inch of trunk diameter.
  • Punch or auger the required number of holes two to four inches deep, spaced evenly around the dripline.
  • Place tablets in the bottom of each hole. Close holes.
  • If chlorosis is severe, increase to six tablets per inch of trunk diameter.

Shrubs

  • For shrubs, use four tablets per three feet of height.
  • For azaleas and other flowers that are from one to three feet in height, use two to four tablets.
  • Punch or auger the required number of holes two to four inches deep spaced evenly just inside the dripline.
  • Place tablets in the bottom of each hole. Close holes.

All Lutz tablets are made to feed for twelve months.
Amending soils is an ongoing process - annual applications are recommended.

"I wanted to write to you to tell you how pleased I am with the results I got from your Iron Chlorosis Tablets that I used on my pine trees. Your iron tablets provided green up and additional growth that I was unable to achieve with other soil amendments or fertilizers.

...I have approximately 100 pine trees on my property, and feel that the results I achieved with the iron tablets is a good indicator that your product works where others have failed.

I appreciate having been introduced to your fine product."
