Sweet Peas often get this way if the weather starts to get too hot for them. It is a common occurence and depending upon where you live starts more or less around the same time each year. They will keep producing as long as it is cool enough; otherwise it gets too hot and they start to die off. Always mulch them in early spring to keep them cool and to keep moisture in. But once the temps start heading toward the 90s, your peas are on their way out.

First season soil is always iffy, it just takes a while to settle in. After it ages a bit, especialy after topping of with compost (hopefully of a different type for added variety) for next season, you should have less of a problem. If you think it is drying out too fast, that is probably the problem. Try a long slow soak to see if part of the problem is simply getting the peat moss fully moistened in the first place. When dry it kind of repels water until its been soaked well again. You might just have to water it more till the dry spell ends and/or hte roots get deep enough.

Hi all, I planted 22 sweet peas in October, mostly in large containers (that later will have tomatoes in them). They sprouted quite nicely and everyone was happy until they got about 3" tall. Now 3/4 of them are yellowing to pale green and looking sort of papery. Their little grabbers are turning purplish at the ends. In the same containers as the sickly looking ones are one or two perfectly happy ones launching up to 4 or 5 inches with big leaves. What is going on? Same watering, same soil, turning the pots regularly (they're on wheels). I've never tried these down south here before. Thanks!

I planted these seeds last year in July and it took them forever to start to bloom. The bloom, I saw was not a flower, but some kind of colorless inflorescence. The vine looked like regular sweet pea vine, and it was very thick. It was shading out light to over plants. It also required constant tending tying and restaking. When I look at the seed package picture (see the link below), I was like this is not what I wanted at all. I don't know if the nicer flowers were coming later,(as pictured) but I had to remove the vine. It had all the bad things about sweet peas, but none of the good things as in flowers. I am looking for an annual vine, because I want something fast growing to take out or change every year. My soil is rich and that is part of the problem. It may have been better for a poor dry soil, and then we had an El Nino this spring, so it got too much water. Here is a link that might be useful: Sweet Pea Perennial Blend Seed
