Yellowing and dying pumpkin leaves early on
This is my second year planting pumpkins. We planted some from the store and some from seed. So far I have about 2 main pumpkins that are the size of tennis balls and growing healthy each day. The vines seem to be advancing several inches a day. The problem is, back at the location where the seeds were planted in the ground the leaves have yellowed, browned, shriveled and died back exposing the garden area like a "bald" patch. About a week or so ago this area was covered with rich green leaves. We water frequently, the vine that is advancing is still a healthy green and those parts of the vine are soft and tender as they should be. The part of the vine in the newly "bald" area is turning woody. Am I doing something wrong, or have some kind of fatal disease? The leaves are dying back as if it were early Fall, they have that appearance. Some of the leaves presentl are a deep hued yellow.
Thanks for the help
