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

I have used these in the past, to help out a Silver Maple in my own yard, and found them to be an excellent tree saver! I recommend them to neighbors who have the same problem too.In 2014, I bought this package for my daughter's 50 year old Silver Maple tree that was in terrible shape. The leaves on over half the tree had turned yellow prematurely, and several branches had already died. When I told her why this happens - poor soil and not enough iron in the soil to feed the tree, or her grass - she was wasn't sure what to do. I told her to hire a tree service to cut the dead branches off so they wouldn't break off and fall on her house, her cat (who sleeps under the tree regularly), cars, or passing pedestrians. The damage those big branches could do was not covered by her home owners insurance, since it's something she can control with knowledge on how and would be excluded from a claim, and she'd likely loose her insurance over it and be sued big time too, if the branches hurt someone.She did hire a tree service to cut the dead branches off and do an iron injection treatment. These helped a lot, though I still saw some yellowing later in the summer, despite what they did. They told her the injection treatment would be necessary annually. I told her the injections would likely need doing 3 times a year for the next couple years, to make up for the deficiency it has likely suffered for some time. She said she can't afford to do that. So, I ordered these, hoping to save her from having to hire the tree service to do the injections - at a much more expensive price no less. I told her to put these in instead and see what happens next year. They really helped save my own Silver Maple from turning yellow last year and this one too; so I know they will do the same thing for her tree.If you have yellowing of leaves on any of your trees and bushes, the first thing you should do is research. Then call your local state Extension Office and see what they might know and suggest. Mine (in CO) said to get soil testing and and hire an arborist. I did both and was very glad I did. I ended up treating my trees and bushes, and all my gardens with iron supplements and an organic fertilizer. This year, I removed all the landscape rock from under the bushes (which over heats the roots of the bushes), added organic compost to everything (landscape and grass yards) and then put down organic mulch under the bushes and trees. I'm sure everything will look much better next spring and I won't need to use and artificial fertilizers.If my Silver Maple (which I would replace with something native if I could afford to) turns yellow again, I won't hesitate to order these put them in the my tree.

The yellowing had taken over my oak and it was losing leaves in summer and with some research I realized it needed iron. Soil amendments won't work and it's a waste of time. I've used these every few years here in OK and have a big beautiful lush oak in the center of my front yard that does a great job now of blocking the WEST SUNSET!Update: I'm using this once a yr now. I have a Bermuda lawn and we are in a high heat drought area so my tree loses a lot of nutrients. My oak is maybe 12 or 15 yrs old and still getting bigger each year, so this has been keeping her super healthy and lush green and vibrant. It's a West facing tree and our yards only tree. Her dead leaves don't drop until right before she sprouts new green ones. It's now May and she is about two weeks into getting new leaves so we are treating her w this product right now. We normally see results in two weeks as long as it rains or we water w sprinkler system. I'm just so proud I discovered this and saved her. I use to fret she had a disease and that wed lose our only tree. So happy that I discovered she was iron deficient....anemic. She's THE BEST TREE in the entire neighborhood!

These were great my husband love the convenience of having them shipped to our door. This product works. My husband loves it. He uses this every year.

My silver maple is about 35 years old and has a trunk that measures more than 4' around. The rest of my property is pretty sparse, so this tree really makes the house and the yard very special.About 5 years ago, a couple of big branches broke off in the wind. It looked like 1/3 of the tree was dead or dying from chlorosis. The soil in this area is so alkaline, no amount of soil amendments were going to save it.When I ordered these plugs, I thought I'd need 100+ for such a big tree. I wasn't sure they would even work. So I started with 30 the first year. I added another 10-20 this past autumn. And the tree looks better than it ever has.No more pale green leaves and brittle branches.I'll continue with a course of maintenance and install 10 or so plugs each year. The plug holes grew over within a year, and the tree doesn't seem to be suffering any ill effects because of the drill holes.I can't recommend this highly enough. My success has encouraged me to plant 3 more silver maples. I'll be sure to install these plugs in them when they're large enough, and prevent them from ever getting so depleted of iron.

I am so glad we were advised to use these capsules on our tree. It's had an iron deficiency for years and we could never figure out what was wrong. We were told it didn't get enough copper. Someone said we weren't giving it enough water. None of that helped. All of it was frustrating! And then we learned about this product. We used it on our tree and were told since it is so late in the year not to expect any great results, but to wait till next year. That was not necessary. Our tree has grown new limbs. These branches are all so green whereas before they were yellow-brown and dying. I would really recommend this product because it works!
