Sounds like your cukes got stressed during growing - lack of water? Cukes tend to turn bitter most frequently at the end of the summer - when it’s good and hot and there’s a drought drying out your plants. The solution? Water, water, water.
I’ve just returned from the County Fair where I ran into one of the old German farmers who lives near me. That was his assessment too — not enough water.
Lord help me, I thought that I certainly had given them enough water, but we’ve had a lot of heat too. Also, since I’ve been watering them with a “ratchet type” spinkler (over head) I think that a lot of the water falls on the leaves and not on the roots.
I hope that doesn’t ruin my other crops.
Red, could you please add FReeper Cincinna to the ping list! Thanks.
