stems cracked on my pumpkin plant
i have 14 pumpkin plants. there was a storm that pushed some of them over when they were younger and the stem cracked. for a while they healed leaving the stem scared. now my plants realy started growing there all blossomed and are about 9 ft long but many of the scared places are opened and are looking dryed and rotted. the leaves and dranches look healthy. what do i do?
