This is my first year growing pumpkins ( Jack O Lantern ), and so far everything looks really good. I am just wondering if I should spray the vines with insecticide and fungicide for prevention or can I be successful without them. Also is fertilizer a must as well, I have been looking for fertilizer but have not seen any 5-10-10, most are very high in nitrogen which I have heard will just make the already enormous leaves get bigger and can possibly prevent female flowers. Any help and advice is greatly appreciated .

Thanks,

Oliver
