Now you can get really crazy with this or keep it very simple. My first year I did not use all the different fertilizers i will talk about here and I grew a nice 275 pound pumpkin. After that I started doing more research found a fertilizer program i liked and the following year I grew a 520 pounder and I am no where near as involved as some people. So it’s up to you but in this instructable I will show you what I have done to consistently grow 400-600 pound pumpkins.
There are a lot of places online to get supplies, I have been using www.hollandsgiants.com and they have been great. You can get everything you need there and much of the fertilizer program that I use is taken from the one that they have designed and have available on their site.
