I planted potatoes in baskets in February. They have come up fine, have kept covering them with soil and hay several times. They are now about 15 inches tall. I read you have to wait until they bloom and the tops die before you harvest them. Since they have not bloomed yet but look like there is a lot of yellow on the leaves do I harvest them now? I also have some in a bed with soil and hay, they're up about the same and very green but no blooms. How much longer do I wait? They are all fingerlings. I did empty one basket that looked pretty bad and got a few out of that one. Just don't know what to do. The ones in basket have a lot of yellow leaves that look like blight. I asked in another thread. Is potato blight anything like tomato and can it spread to tomato plants? Anne
