MediCapFE FE1210 Systemic Iron Tree Implant, Pack of 10

It appeared I was losing my young oak tree to chlorosis. I looked into getting an arborist to treat. Not cheap, so discovered this product online. It's affordable and works amazingly well. You can see in one photo how the leaves were yellow with dark green veins. I bought this product and could see improvement within 2 weeks. The leaves are turning green in most areas of the canopy. The other photo shows new green leaves growing on what had been a bare branch. WOW!Different size capsules are available for various size tree trunks. An easy way of gauging your need is to use a string to wrap around the trunk 6" from the ground. Then measure how long the string is for the circumference of the trunk. Jot that number down. You'll use it again to determine how many capsules to use for treating your tree. To get the diameter, divide that circumference number by 3.14. Use the diameter to figure out which size capsule to buy. Back to the circumference number again: the circumference is divided by 4 for usual dosage OR divided by 3 for severe cases of chlorosis. I used circumference ÷ 3 for severe dosage. I used the correct size drill bit. And I put painters tape on the bit to mark how far I needed to drill into the trunk. I drilled into the trunk right up to the tape. Perfect depth each time. A large bolt helped me gently tape the capsules into the trunk. Directions are included, but can be a little confusing.I highly recommend this treatment!!!I have since followed up with "iron" stakes in ground along the drip line to help correct the pH and correct chlorosis longer term.

I live in Colorado and planted a pin oak in the front yard. I have since learned that they don't like clay soil, so my tree was struggling with poor foliage and yellow leaves. The tree is about 15 years old and a little stunted but it keeps trying!I implanted these in late February and the tree looks much greener this year. With the exception of one branch, the leaves are greener and there are a lot more of them. I do believe that I made two mistakes; first, I don't think I drilled deep enough into the tree and I think I should have angled the drill a little more because you can see some iron weepage on the bark. Nonetheless, the tree looks much better than when I tried to give it iron by adding it to the soil.

Works well - if this is what you need. Within a couple weeks both of my trees went from yellowing back to green. This is my second batch. You'll likely need to do this treatment every year or two it appears. Take care to follow the directions and drill out the holes the proper depth and diameter. I also believe it may help to angle the hole slightly downward. Loses on star only on value....for what it is it could be half the price.

We live in Maryland, north of DC in a suburban neighborhood. Our river birch tree (about 10’ diameter at the base) has always struggled, with skimpy and small pale leaves that seem to drop off throughout the summer. It didn’t seem to be infested with any kind of insect that we could see, and the trunk looked normal. I’m not an arborist at all, but I did some research on-line and saw some suggestions that birch can be susceptible to something called “iron chlorosis”. I was skeptical about this product but when I mentioned it, my wife encouraged me to try it. It was pretty easy to administer (drill small 3/8” holes and hammer in the plugs as per instructions). The tree responded within weeks and after a month is now doing great! Originally there were 3 trunks, and the smallest one died last year. The second smallest one was pretty bare and probably would have died as well. Now it has green leaves bursting everywhere and the main largest trunk now has full green leaves. It is obvious to me now that this product has saved our River Birch. We’re very pleased.

I cannot believe how quickly we saw results after inserting these iron implants!Our Silver Maples had iron chlorosis so bad they were coding! The water soluble iron soil treatment wasn’t doing anything. I really did not want to have to cut them down or pull them up. I did some research and thought we’d try these as a hail mary attempt. It already being summer I figured we would have to wait until next spring to see if we would get results. A couple weeks later and our trees actually look green! Most of the yellowed leaves have turned green and there is even new growth of green healthy leaves.There is a bit of an ashy burnt look on the trunk an inch or so around the areas where the implants have been inserted. That’s probably unavoidable in giving such a large local dose of iron. I don’t mind—all I see is green leaves!

I have a forestry degree and I’m also lazy, I mean energy efficient in my methods.This type of iron treatment is very effective and super easy, barely an inconvenience.I had a maple that I tried several in soil treatments but I wanted long term with zero effort on my part.I knew when we bought the property seven years ago that this maple would die without supplemental care. This was the year that chlorosis was terminal.We put theme in the trunk and now one month later, it’s green and will survive.100 percent recommend this product.

The I plant helped our river birch tree but now I’m worried because it looks like last year’s implants have caused rotting to occur in the hole where they were placed. Would love to hear any advice you have!!

Very effective. Easy to use. Instructions are clear. Revived a tree that suffered from chlorosis / iron deficiency.

Brought back a Pin Oak from the grave. Still have some yellow leaves, but I can see the progress after two weeks.
