Help---cuke Seedlings---edges of leaves yellow

zabby17 · July 8, 2012

Hi! Any experienced cuke growers out there who could give some advice?

I'm growing some replacement seedlings for some cucumbers that were sadly murdered in their youth. I grow a lot of tomatoes but don't know much about other veggies and haven't had great luck with cucumbers; I thought it was early enough to be worth trying again, though, even if I get a small, late harvest.

I wanted to let the seedlings get good and sturdy before putting them out, because I've had more insects than usual this year (I garden organically); some replacement squash I direct seeded was munched to death the day it emerged from the ground. So I started indoors under lights.

When my seedlings got to be filling out their 3-inch pots, I potted them up into six-inch pots two days ago. Now the edges of all the leaves are turning yellow; the rest of the seedling still looks a healthy, dark green.

They are in a standard potting mix, which I've been keeping moist.

I know cucurbits aren't supposed to like having their roots disturbed, so maybe
the potting up is causing them distress? Or should I be letting the soil dry out between waterings by now? Should I fertilize?

There may be no hope for these babies but I'd love to give them a chance if I can. I do love lemon cucumbers, and have such a pretty little trellis for them made from an old wooden clothes-drying rack....

Any advice appreciated.
