Geranium Leaves Turning Yellow?

I don't know where you live, I'm in Calif, but for the most part, geraniums prefer drier soil. Yellow leaves usually mean too much water. If you have more of a clay soil, like I do, you should mulch it, add sharp sand, anything to open up the soil so it drains better. I have this recipe for fertilizing geraniums, which I read in a Jerry Baker plant book; in a watering can or bucket, put in 3/8tsp instant tea, 1-1/2tsp baby shampoo or liquid dish soap, 1-12oz regular beer & 1-1/2gal water, mix well. Then take 1 or 2 handfuls of epsom salts around each bush, depending on size & trowel it into the soil & water it in with the beer mix. This will do 1 to 1-1/2 good size bushes. Do this like 2x a year & they will bloom like mad. It is good for all acid loving plants. Other plants like fuchias use less of course, they are more delicate.

My geranium is very small, lives indoor and is potted in a clay pot. Will your recipe adapt to these growing conditions?

Have had quite a few geraniums over the years and yellow leaves are usually a sign of over watering. You need to make sure the pot has good drainage, water well and then let the soil be dry (but not too dry) before watering again. Hope this helps :-)

Sounds like too much water. They do not like their roots to sit in water. Make sure you use planters with holes in the bottom or put rocks/broken pottery in the bottom before adding soild.
