Picture of Giant Pumpkins make Giant Jack o Lanterns
     I have been growing giant pumpkins for awhile now and after my first year I was hooked I had an amazing time growing them and they made an awesome addition to my Halloween décor for many reasons.  First of all it’s just incredible that something can get that big. I am just amazed you can grow a 500 pound pumpkin from a relatively small seed.  Secondly I can pretty much guarantee that no one else in your neighborhood will have anything close. I don’t think we had one trick or treater not make a comment or take a picture.  Also it gives you some insurance against would be pumpkin smashers cause they are impossible to lift on your own.  Lastly the sheer size of the Jack o Lantern when you carve it allows you to do some cool things, more on that later.  So put in a little work this summer and you will have the biggest jack-o-lantern on the block.
       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.

Well I tried a giant pumpkin this year, unfortunately I wasn't ready for vine borer bug, I pulled out a bunch larva, got rid of a clump of eggs, and removed two vines. I did the best I could and patched the holes up with mud, but I just don't know what to think yet, I guess I will have to try again next year. Beware pumpkin growers! the vine boarer bug will really ruin a couple months of work.

Super... Will try next Year here in Germany in my compost....200 pound would be Good , so You Feed the plant with milk?I heared about that... Great Job

You have very nice soil there. like I said I live in Lancaster Pa, and we have rocky soil. Although, you seem to be much more of a gardner than we are.

Boy, I would love to harvest a pumpkin like that. As we all know what happens when you stick a pumpkin in a compost pile. My last years pumpkin made some really good pumpkins this fall, as they were planted (by accident) in the compost/brush pile. The biggest I ever had, but really there kind of "average, big". If I can get this parental approved, I would collect horse dung everywhere (good thing I live in Lancaster Amish county).
I have seen such a big for the first time......
