Bacterial spot? You might want to send this pic to your county extension for better-informed advice. Here is a link that might be useful: UF/IFAS Extension

Esther B You do not have the area you live nor the zone you are in but it sounds like your rose has black spot. You can treat it with a fungicide such as Bayer or Ortho for fungus and disease control. Try not to use Bayer 3 in 1 or an insecticide/disease control combos spray. Below is a link that may help you.

Two years is a long time. When did you last repot? What are you feeding it? there can be several culprits, but likely it is just a ph imbalance from the potting medium breaking down. it COULD be chloramines, if your city just changed their water processing. when you repot, if you are looking to re-use that self watering pot, wash it well (maybe even with some vinegar, but rinse that really well). and prepare a soil mix with probably about 40-60% perlite mixed in a commercial African violet or seedling mix - try to find perlite and soil that have no fertilizers added - those can do really strange stuff if put in a self watering pot. i assume your plant has a "neck" (or stem). it doesn't hurt the plant, but some people don't like the looks. if you want to "rejuvenate" the plant, (i don't know if the article still is to be found here somewhere). the measures you take are a bit more drastic than simply repotting. Materials needed: potting mix (moistened, not sopping wet) pot. clear ziploc bag big enough so that will enclose pot & plant without touching the leaves a knife Procedure: take the plant out of the pot wash the pot fill the pot with pre-moistened potting mix (it should clump when compressed, but not be wet enough that you can squeeze water out) remove all flower buds and the outer rows of leaves until you get to the healthy center crown (anywhere from 2-6" across i think is fine). sever the stem about 1/2-3/4" below the lowest row of leaves place the plant in the pot, pushing the stem into the mix, bringing the bottom row of leaves near level with the soil line don't fill the reservoir with water put the entire thing, pot and plant, into the ziploc bag, blow it up for volume then close it. place it somewhere bright, but make sure there will be no direct sunshine hitting it (good way to cook a plant) wait for new growth. usually roots within a few weeks. if there is too much condensation, open the bag to air it out, then close it again. water if needed (probably not necessary) when you see new growth, open the bag bit by bit over the course of a few days, slowly acclimatising the plant to "normal" humidity levels. when you take the plant out of the bag, you can fill the reservoir Disclaimer: this is how i read it everywhere. i always strip the plant down to 2" or less, and rarely bag them. Do this at your own risk, if you are attached, root a bunch of the leaves you take off, as backup. good luck Karin

Any ideas what is going on here? Green beans: Also this white stuff and green spikey stuff on cucumber?
