Ok... the medium has started to dry out and the baby is starting to change to green. Im pretty sure that ive been over watering them in an attempt to keep them moist before they sprout. Thank you... and next time ill post a picture with my question. :) This post was edited by LindsayConrad on Sat, Apr 5, 14 at 12:05

It could be over-watered... so if thats the case will it turn the proper color when the soil dries out a bit? That is the most common cause but while any new growth will be darker color the pale/yellow leaves usually die and fall off. Whether that particular plant will survive all depends on how much root damage has been done already. Dave

greenthumbnick I'm also growing Purple Hulls, and though I don't see any aphids, every time I go out to havest them I find big black ants perched right where the pod detaches from the stem. I just shoo them away since they don't bite. The plants must exude something very attractive to some insects.

Thank you for your reply. I was worried about the soil volume also because I read that Sweet Peas are heavy feeders. The water is no problem. I poked a drainage hole in each egg shell before I put the potting soil in, and watered them well. They all drained out and I misted them every day to keep them damp. This morning I set one out. I broke a lot of the shell, especially the bottom and pressed damp dirt around it. It's my test plant. If it makes it through the day, I'll plant the rest tomorrow. They should be planted directly in the ground, but I was afraid the gardners would weed whack them before they bloomed. The little egg shell planters showing above the ground should give them a clue that these are MY plants and not weeds... Sigh I have a border for plants between my pool and the golf course. I can't wait to see the beauty these sweet peas will bring. I had a new one poke it's little head through the soil today, so all but one seed has "hatched." I like the fact that the egg shell will add nutrients to the soil and help my little sweet peas do what they do best, bloom and smell soooooooo sweet! My next effort in my egg shell "incubators" will be fennel seeds and nasturtium. It's very hot here (108-114 degrees average) in the summer, so I'm starting early. The heat starts in June. It rarely freezes here but I'll know from the news if it is going to freeze, and I'll cover my seedlings to protect them. And also, just so you know I never crack my eggs in the middle anymore because I want more soil volume for the seedlings. I crack the top off, let the egg slip out, rinse the shell, and THEN back in the tray it goes for my little seeds. When the eggs are all gone, I have a dozen new little pots for seeds. Since the shells are good for all plants, I use the tops mixed with my coffee grounds as a sort of mulch. My jalepeno peppers LOVE it!! Thanks again for your reply:-)
