Couldn't tell you about azaeleas since I don't know if they respond the way roses do, but about the roses, they are just suffering from a little transplant shock. Just pluck off and destroy the yellow leaves and wait for about a month or so to see what the roses do. By the way, I wasn't clear if you meant the roses are NOW planted in containers or in the ground. Either way, they need good drainage (and plenty of sun) or they will get yellow leaves that fall off. If your drainage is good, then it may be that you are watering them too much--or if they are in containers, that they are setting on trays that retain the water, which is too much for the plants. Other things can cause yellowing leaves also--like under-watering! But if you are like most new rose owners, you are more likely over-doing the care and watering too much as a result. But you will have to determine whether your soil is moist or very dry. I still think it is mostly transplant shock. Let us know how it's going in about a month--OK? Kate

Thanks Mike. I think the pot is big enough and it doesn't have any diseases, but I read some other posts and they mention watering with a vinegar solution so I'll give that a try as well.

I had precisely the same situation: a store-bought plant that was doing great for a while under fluorescent light (a CFL in a gooseneck lamp), then the lower leaves started yellowing, showing spots, etc. I took a really close look under a low-power microscope, and found out I had mites. These little suckers are nearly transparent, unlike the black ones that are relatively easy to spot. I believe that the plant cuts off nutrients to the infested leaves as a defense mechanism, since the mites can't suck the juices from a dry leaf. Use a miticide if you're OK with chemical treatments; Bayer's 3-in-1 has a particularly effective agent in it. If not, or if your state hasn't approved the stuff for sale (you cannot buy it in NY), you can try my approach: fill a bucket with soapy water (dish detergent, ca. 1/2 tsp per gallon), and shove the entire plant, upside-down, into the water. Slosh it around, and up-and-down, for about a minute. This removes the bugs, drowns the ones who won't let go, and I think it might even damage the eggs (tiny white specks on the bottom of the leaves.) Repeat once a week for at least 3 weeks (the mites have a 10-day life cycle), and maybe once a month after that to keep 'em down. The mites prefer a dry environment, so this treatment, along with misting, will prevent them from doing noticeable damage. I think the real problem with keeping these plants indoors is that the mites are not exposed to their natural predators, so their population can explode very quickly. They are incredibly persistent, and they will keep coming back time and time again if you don't manage to kill off every last one of them (and every last egg as well!) Unless you like having ladybugs crawling around the house, you're stuck with regular washing, or chemical treatments, to keep them under control.

I have done some research and I have talked with the people at the New York Cooperative Extension and found that it is Early Blight that has taken my tomatoes. I have sprayed with a fungicide but the rain keeps coming and I think the plants are not going to make it. Very sad as they are my favorite and usually my best crop.
