in the ground or pot?

I soak used roofing nails in vinegar then add a table spoon of that to a gallon of water. Feed the tree with the solution. It worked well for me. Used roofing nails are free if you have access to them.

Photos.... Photos... What you may "see" as iron deficiency may well be something entirely different. Are you an expert in Iron defiiciency, or are you asking for help?

Steve,

I think roofing nails are zinc; but I am not expert in that arena

Rust is insoluble. An old wife's tale to ignore.

Please show us the plant.

John. Roofing nails are made of steel and have a very thin coat of zinc. Used roofing nails have lost a lot of that zinc coating.

Steve,

I am good with that... so?

I was growing a meiwa kumquat tree from seed and they have Fe and Zn problems and there was no finding resources in Cincinnati.

Solid zinc will react with vinegar to yield hydrogen gas and soluble zinc acetate. So vinegar will remove whatever zinc is left on the nails,

Rather than using home remedies which may or may not work (usually not) and dry organics to fertilize container grown plants (which are hugely ineffective in releasing and providing nutrients under container culture) why not invest in a high quality water soluble fertilizer - like one of the Dyna Gro products - that contains all the necessary trace elements as well?

If one is providing the nutrients these plants need and in the quantities they require, then one no longer needs to worry about issues like chlorosis or other deficiencies. It sounds very simplistic but it really does work!!

I fail to understand why this wouldn't be the first approach any educated grower would follow..........this isn't rocket science folks!

"So vinegar will remove whatever zinc is left on the nails,"

And will still leave you with an insoluble source of iron that won't do your plants a darn bit of good!

Echo Gardengal! Matt, in my opinion, you are not giving the plant food that it can absorb. It is starving. Go ahead and dump the organics in the backyard and give the potted plants the good stuff. ...and do report back with pictures - you know we love to see pictures! - George

Why on earth won't you use iron chelate? It is the best remedy for iron deficiency in citrus, If you keep fooling around with organic fertilizers, your tree will keep having these deficiencies.

Silica, I would use chelated iron however I cannot find it anywhere

lol- and micronutrients, like zinc, are often overlooked.

Matt, you might not be getting the point here. If you keep adding this and that, in which you probably have no idea in what you are doing, any one of those single nutrients can impede another if not used correctly.. Why not let the experts do this for you and get a fertilizer that has everything you need in it? Organics will not work in a pot...

With all the money you are spending on singular nutrients, you could save a ton of money just buying one that works great. I've been down your route, and it just won't work no matter how hard you try even with your good intentions..

Hi Matt)

The scientist that specifically develop these fertilizes for certain plant material.

Orher than Dyno Gro and certain Miracle Grow and other fertilizers with all the micro and macro nutrients you need and in balanced proportions , they are also developed with certain ratios of nitrogen, potassium , and phosphorus.

Then too there are many that have been growing their trees for years in containers here and they will steer you in the way in which to need to be even more successful through their experience.

Most of us will agree that trying it the way you've been doing will not provide the best care for your trees.

Goid lucj in your endevors and hopefully you will get them lush and green and in the best vital health you desire

Trickyputt, WTF ???????????????????????????????????????????????????????????

Silica don't feed the troll please :)

But Trolls need feeding too. Because you do not care for people learning how to grow on their own I deleted the post that offend you.

Tricky point, get lost since you have nothing nice to say or I shall have to report you to my friends at Houzz...I have never seen such a crude and rude person here in the ten years or so since I have been helping. There is no place for you here I will make sure of it if you can't be respectful or considerate..I suggest you delete your last one too

silica. Just a heads up. Houzz will be coming by as soon as I talk to them. and probably mistake your post for something inappropriate. I don't want him to think anything bad about you since you have been a wonderful help here and I would miss all you have to offer if they banned you by mistake. Waiting on you )
