Plant Seedlings Turn Yellow And Shrivel Up And Die

Question

my new cantaloupe seedlings that have been planted for 2 weeks are turning yellow and dying. I have them covered from hot sun and they are watered well when needed….. watermelon seedlings also have died?

Answer 1

Did you harden them off before planting them? If you started them indoors they can be gradually exposed to the bright sun. Also, have you checked for aphids or spider mites? There are a number of possibilities. I hope these articles will help:
