My pumkins started off great. last year I had 1 big and 1 smaller one. so far this year I have about 20 pumpkins and more keep comeing. So my guestion is shoud I cut off the small little starts to help the bigger ones grow or just let it be.I have noticed a good deal of the leaves are dead or almost dead so this might help them. also there are these little grey bugs that are on the under sides of the leaves how shoud i get rid of them or do the hurt??

All imput would be appreciated.
