The best solution for iron chlorosis is to avoid planting pin oak in alkaline soils.
According to Michigan State University Extension, there are four principle treatments for chlorotic pin oaks:
- Soil application of iron sulfate or sulfur.
- Soil application of chelated iron.
- Foliar sprays.
- Trunk injection.
What can I put on a pin oak tree?
- Treatments. Iron chelates or chelates containing iron and sulfur also can be sprayed on a pin oak‘s leaves, but covering all of a large tree‘s leaves is difficult, and the result may be only temporary. A trained arborist can inject iron into a pin oak‘s trunk.

How do you add iron to an oak tree?
If a rapid response is needed to correct a chlorotic condition, a foliar spray with iron sulfate or iron chelate solution may be applied when the tree is in full leaf. A rate of five pounds of iron sulfate in 100 gallons of water (2.5 ounces iron sulfate in three gallons water) is recommended.
What is the best fertilizer for pin oak trees?
The best fertilizers are those with a nutrient ratio of 12-6-6 or 12-4-8. To supply the oak fertilization recommendation of 2 pounds of nitrogen, you’ll need 16.6 pounds of either fertilizer for every 1,000 square feet of gardening space.
How do you inject iron into trees?
Trunk injection or implantation Iron compounds in dry or liquid form can be placed directly into holes drilled into a tree’s lower trunk. Systems also are available that use plastic tubing and tees, capsules of various types, or a hypodermic-like tool to place iron materials into the tree.
How do you fertilize a pin oak tree?
Fertilizer can be injected with water or placed in holes dug into the ground, 18 inches apart, along the tree’s drip line. Fertilizers should be applied at a rate of two to four pounds of actual nitrogen per thousand square feet of area.
How do you fix iron deficiency in oak trees?
Iron sulfate or iron chelates can be applied to trees as a foliar spray. This can often provide a rapid green-up within days or a week. Some leaf burn is also possible, however. The treatment does not address the underlying cause and the effect may only persist for a year.
Can a tree get too much iron?
It plays an important role in respiration, photosynthesis and the production of healthy green leaves. Plants can suffer iron deficiency with symptoms of chlorosis and stunted growth, according to the University of Hawaii at Manoa, but plants can also take in too much iron, especially under certain growing conditions.
Does Miracle Grow work on oak trees?
MiracleGro Tree & Shrub Plant Food Spikes. MiracleGro food spikes for shrubs and trees provide nutrition directly to the roots of your oak trees. Most oaks are deciduous, but some are evergreen.
How can I help a struggling oak tree?
To save a dying oak tree, employ the following tactics:
- Prune and discard any diseased branches.
- Spray diseased areas with fungicide.
- Inject fungicide into your oak tree.
- Fertilize your tree.
- Mulch near the base of your tree.
- Ensure your tree is not overwatered. Dig drainage ditches if the tree is in boggy ground.
Should I water my oak tree?
In most circumstances it is not necessary to water mature established live oak trees. Shallow watering can in fact cause additional problems. Over watering or improper watering of oak trees may promote the growth of bacteria that can damage the root hairs and the ability of the tree to absorb water from the soil.
How do you fix iron deficiency in trees?
For large trees, the most effective treatment is a trunk injection of iron for rapid greening followed by soil applications of sulfur and iron. Treating the soil will reduce recurrence of the problem. Trunk injection can be done at any time of the year when the tree is not frozen or under drought stress.
Does my tree need iron?
Trees need iron to manufacture chlorophyll. When a tree lacks chlorophyll, it can’t produce adequate energy via photosynthesis and the tree will begin to decline. A tree in decline is also more susceptible to other diseases and insects.
How can I add iron to my soil naturally?
You can add chelated iron powder or blood meal directly to the soil to add iron. You can also add fertilizer or your own compost, as long as the iron content is high enough. Another option is to add chelated iron or iron sulfate in liquid form by spraying the leaves of the plant.
Is a pin oak a good tree?
Pin oak is easy to transplant because it has a shallow, fibrous root system. Pin oak’s ability to thrive in nursery culture explains why it is a common tree found in garden centers. It is a great tree for large landscapes, but its hanging lower branches make it a high-maintenance street tree.
What is the lifespan of a pin oak tree?
In its natural environment pin oak is a relatively short-lived, fast-growing pioneer or riparian species with a lifespan of approximately 120 years against many oaks which can live several centuries. Despite this there are many examples of pin oak that exceed this lifespan.
Should I fertilize my oak trees?
Oaks should be fertilized once or twice a year. In particular, fertilizers that release large amounts of Nitrogen quickly into the soil can encourage structurally weak growth that could cause problems and could potentially promote spread of oak wilt throughout a tree.
