My favorite Fall perennial is the chrysanthemum & I try to get as many different colors growing as I can. I have noticed though that the pretty white mums soon get a purple tinge to the white color every time I plant that color! What causes this to happen? Also, do I need to remove & plant fresh every few years? They seem to get rangy & sparse even though I prune them back during the summer (how late can I do this so I don't prevent any of the Fall blooms to develop? I prune to try & make them bushier & more flowers). I do plant the nice fresh prunings & often do get some of the cuttings to root, though the local snails sure do like the taste of new,fresh growth (they leave the old plants alone!)! The mums seem to bloom early, I clip the old blooms off & then they bloom as usual in the late Fall here.

This image is from the adjacent plant, watermelon beefsteak. It's more affected by this than the cherry. It looks like the leaf I pulled off earlier is more of an exception than the rule, in that the veins on the leaves are fully affected. I'm hoping it isn't the disorder that is uncurable.....

I'm in Ghana. Temperatures are going as high as 35 degrees Celcius and only as low as 22. De formula is just fish scales, innards and grass clippings. It's been rotting for more than a month. It's a food sweet potato plant and the sawdust is partially rotten. It's black but soft wood particles can be felt. I thought sweet potatoes can be grown in low-nitrogen media. And why should it be fed often? I read somewhere that the plant should be fed enough nitrogen to make more leaves to create a lot of energy to make potatoes
