They shouldn't have died. Did they drown? I know there has been alot of rain in the east.

Lynn, As your onions mature the leaves will start drying out, and the tops will start falling over. Once about half the tops have fallen, you can use a rake to knock over the rest, that will help prepare them for storage. Once the tops are mostly dried, they can be dug or pulled from the ground, and then left to cure for approximately 2 weeks. Since I have sunburned onions before, I cure them in a well ventilated, shaded area for a couple of weeks. Then you can clean the roots off and prepare them for storage.

The yellowness of the leaves with greener color near the veins is called chlorosis. Those leaves are chlorotic, which is a condition caused be a nutrient deficiency. Most likely it is a nitrogen deficiency. Even though beans are said to need little if any nitrogen fertilizer when grown in average type soils, they need some nitrogen and your soil may be lacking in it. Is that a lot of bark chips or similar material I see in your soil? Bark uses a lot of nitrogen as it decomposes. I suggest applying a treatment of solube fertilizer such as Miracle grow. You will know in a very few days if it has been successful. The leaves should get nice and green like Anney's. So far as insects are concerned, I agree with Anney that Mexican Bean Beetles can be very destructive. I don't see any evidence of MBB on your plants. The most remarkable solution to a MBB problem, if you should have it, is Pediobius foveolatus. There is a thread about it here somewhere. The drawback is that it is expensive. Probably not worth it unless you grow a lot of beans. Rotenone has worked for me but I avoid using it if possible because it kills bees. When I use rotenone I apply it only to plants not in flower. I would not worry about insects unless I saw real damage occuring. Jim

looks like your media failed .. and you either drowned it.. or droughted it ... or summer sun is too much for it ... especially if there was media failure ... why dont you give us some facts about it ... pix alone dont make for good guessing ... how long you had it when repotted if ever how do you water it etc ... there is a very active houseplant forum .... if you wish to go beyond what we might tell you ... ken
