How do I know if I overwatered my tomato plants?
Early signs of overwatering in tomato plants include cracked fruit and blisters or bumps on the lower leaves. If the overwatering continues, the bumps or blisters on the leaves turn corky. Meanwhile, the roots begin to drown, die and rot, which reduces the amount of water the green part of the plant receives.
Which deficiency is responsible for the shedding of leaves and fruits?
