Espoma Organic Iron-Tone 3-0-3 Organic Fertilizer and Plant Food to Help Correct Iron Deficiency (Chlorosis). 5 lb. Bag. Turns Yellow to Green, Non Staining Iron

Used them on Vinca just like those pictured on the front of the package. The leaves turned pale yellow after a few weeks after planting. No noticeable difference after regular fertilizer applied. But after only one week after applying IronTone they were much better. After two weeks the leaves are deep green just like those on the package! Very pleased.

I built some new raised beds and filled them with raised bed soil and compost. I planted tomatoes, peppers, beans and they started looking a little yellow. Without a soil test, I wasn't sure what was causing this but after research, found that my soil could lack iron. I trust the Espoma brand, think it's a good value, and use some of their other organic fertilizers. After applying and watering in, I noticed greening up after about a week, with consistent results since then. The plants are healthy green, and producing fruit and veg. I will continue to purchase Espoma products based on my results.

Wonderful flower fertilizer. Easy to use , great value, plants stay healthy

Product is great. The box it was delivered in was to big , it allowed the bag inside to break open.

Easy to apply and ideal for greening up your container plants, as many will show leaf yellowing after a month or two of watering. I apply this three times during the growing season, along with the appropriate fertilizer for the plant type and a micronutrient supplement for my container citrus and it works great.

I honestly couldn’t figure out why my hydrangea leaves were turning yellow. After some deep research turns out my plants were low on iron!! Who would have guessed! After figuring out what the issue was we got straight to the problem. We ordered this stuff and it had been amazing! Slowly but surely the leaves have grown and the green has been developing. The green veins are stretching and soon will grow and all the yellow coloring in the leaves will disappear. I have a before picture of when the leaves were yellow and now starting to turn green. Now keep in mind…this only works and will help your plant if you see the classic yellow leaves with green veins. That’s how you know the soil is low in iron and you have to boost it up the help your plants. I hope this helps and bring you a healthy garden.

Its organic. That means all nutrients came from natural sources. Use outside only unless you have a strong nose. Hint: Doesn't smell like chocolate candy...

Keeps our river birches from displaying yellow leaves. Neighbors use as well for evergreens.

I searched countless garden centers for an iron fertilizer to help my gardenias, but all I could find was aluminum sulfate. I finally found this product on Amazon, and it has made a noticeable difference. It has significantly reduced the yellowing leaves on my gardenias. Highly recommended!

It helped with my hydrengea yellowish leaves.

The format is very easy to use and the size is quite comfortable to carry around. These are things I look for in any product.

I imagine it will take some time to see any results, but came as is described.
