25-Pack FE SUPER Systemic Iron Tree Implants for Control of Iron Chlorosis, 1/2-Inch

My tree was suffering from iron deficiency. This stuff brought it back to life and has the tree looking much healthier. The before and after photo is just a 4 week difference after the treatment. Highly recommend this product.

I’m very happy with the results. See the before and after picture. After about a month. I started seeing results after two weeks of the application.

Put these in my tree because it was really suffering and looked like we might of lost it last fall. My husband and I drilled a spiral of holes around the tree and inserted them hoping for the best through winter. Now it’s spring and the Maple tree flushed back out with leaves this year and looking very robust.Hoping that with liquid treatments that Maples need during the spring summer that it will be better this fall.

Hard trees in our front yard struggled for many years they would sunburn real fast not a lot of leaves drilled a hole, but the plug-in hammered it in as the instructions say this year I actually had to trim because it Came in so good nice and green very good for iron lacking areas

We have used these in Oak and maple trees for ten years and trees are super healthy. Provides iron for a fraction of the price of tree services and it only takes my husband about an hour every spring to treat 10 trees.

My tree didn’t have time to grow yet this spring but they where easy to install.

I wish I'd known about these years ago, I could've saved myself a lot of wasted time and money. I had already known that the trees, all pin oaks, needed iron. All 3 trees were affected differently yet all 3 were planted in 1997 and weren't more that 75 feet apart planted in my back/side yard. One tree started turning yellow years ago, about 2010. All 3 would bloom normally, leaves would start to grow, but as early as mid May one tree's leaves would start to turn yellow. By June most of the leaves would be yellow/brown and by July the tree would look like it would in fall, October, ready to drop all its leaves. The second tree was affected less, just spots here and there on the tree, maybe only 40%. The third tree, in my side yard, was literally two toned starting in May. Actually, it had 3 different shades; one third lighter green/yellow, one third just a slight yellow tinge and one third normal dark green. I read all I could about feeding the trees, even going so far as drilling 1/2" holes in the GROUND around each tree and pouring an iron rich solution into the holes. That did nothing, I thought they were just going to slowly die. The lower branches on all the trees would be dead the following year. Not sure how I stumbled upon the Medcap capsules but I figured that since I'd tried everything else I had nothing to lose.I was, naturally, leary about drilling a dozen holes into each tree but I knew if I used a nice sharp bit, took my time and made sure I didn't drill into the tree too far I should be OK. I drilled into all 3 trees near the end of March this year, installed the capsules, and waited. Naturally you won't see anything right away but by the end of May I knew it was working. No yellow or brown anywhere on any of the trees! I kept waiting, thinking that al least a few of the branches would turn yellow but it never happened. This is the first year I've tried it but so far so good - it looks like my problem has been solved.A couple of things; if you look at the pictures I posted, the tree that's pictured is in my side yard. The 'before' pic is from October, 2019. The 'after' pic is from September 19, 2020. I didn't realize it at first, but the brown fur ball in the grass in both pictures is my dog Maxie. The other picture is of a trunk that's weeping a bit after having the capsules installed. This is normal but I think you may be able to minumize the weeping somewhat by drilling the holes at a very slight downward angle, maybe only 5 degrees or so. Also, I've noticed that if you drill the holes just slightly deeper the hole won't weep as much. The thing is, you have to get below the bark so if you drill 1/8" deeper it's better than drilling 1/8" too shallow.Anyway, hope this helps, it certainly did for my trees!

It's been 2 months, and only 1/2 of the tree has turned somewhat green.
