| Hello, everyone! I just bought a bottle of liquid chelated iron to green up the foliage on all the roses. BUT, the instructions on the bottle are far from clear.... so much for a one foot tall shrub, a different amount for 2-3', a different amount for potted plants, etc. Is there a general rule of thumb for using this stuff on roses? For example: How much fertilizer per gallon of water? One gallon of the mixed fertilizer per bush? Anything different from roses in large (20") containers? I don't want to mess it up and kill anything. Thanks for any guidance you can offer! |

| I used Fertilome LCFe many years ago on some of my roses when I lived in an area with a lot of limestone rock formations. I would suggest you use the lowest dose recommended on the bottle to start with. I just looked at a Fertilome LCFe label on line & the lowest dosage was 2 TBSP per 1 gal of water, apply 1 gal of this solution to a 2ft high plant (if you are using another brand of LCFe, follow their mixing instructions). Apply as a soil drench to a couple of test plants, wait 3-4 weeks & see if it resolves the problem you are trying to address. If it causes some other problem, don't apply to your other roses; if it solves your problem, then apply to your other roses; & if it partially resolves your problem, then you may want to up your dosage per plant. Also remember LCFe stains everything....clothes, skin, plastic buckets, concrete, etc. so handle accordingly. |

| Just a heads up! I used it on my Rhododendrons....It made the most beautiful forest green foliage. (Sprayed). So I did it again. The rhodies were in bloom! About two hours later, I looked out and the blooms were healthy, but had taken up the iron and were all black edged. I don't think I would do the roses if they are in bloom, and you plan on spraying. The foliage was gorgeous. Good luck! |

| Thank you for the responses and for that warning! I plan on using it as a liquid drench. Our local society's rose show is the first Saturday of May, and I just want to green up the foliage on a few bushes, including a Reine des Violettes growing in a large container. Will go the low dose route that you recommended, wirosarian. Thanks again! |
