Blossom End Rot

Kaysville, UT(Zone 5b)

Are tomotoes the only veggie that can get blossom end rot? I have some yellow summer squash that start out great, but then the end where the blossom is turns brown and rots. Is this too much nitrogen like I've read or are there other things at work here?

Dear Bunch,
Squash can and frequently do get blossom end rot. It can be caused by a calcium deficiency or uneven watering. I would add some Liqui-Cal or even Gypsum to the root zone and keep your water schedule consistent. It's most likely a calcium deficiency though.
Good luck

Bradshawbunch, the rotting end of your squash might also just be from incomplete pollination. When the female flowers are not fully pollinated you'll often see the growth of a young squash then it browns or shrivels then dies off. This happens due to the fact that in the early part of the plants life there are not male and female flowers at the same time. Never fear though, as the plants get bigger and mature there will be plenty of both flower types and you should see better success.

As for other plants that get BER, both tomatoes (as you know) and also peppers are susceptible to it.

Happy Gardening! Wishing you great success!
