One tip I would give anyone that wants to grow a giant pumpkin is make sure you do the basics very well. Get your soil tested and understand what is required in a soil to grow a giant pumpkin. This is an ongoing effort but the basics, if you can find someone to guide you are somewhat simple.
The next tip would be to understand the different cycles that a pumpkin plant goes through during a season. This takes time to learn but when you recognize what a plant is doing you can take advantage of it.
The last time is to understand proper watering. This also isn't quite as simple as it would seem but again the basics are pretty simple. Keep the soil lightly moist.
For my own benefit I'm writing hear what I have done differently so far this season so I can learn from it for future seasons:
- Tripled the amount of alfalfa that I put into the soil in the fall and spring.
- Used about double the amount of bilogicals on the soil this year that I have used in the past and with that I added beneficial nematodes to the soil in the Spring.
- Watered a little more.
- Did a cover crop that I tilled in later and I put down myko with the cover crop.
- Did more targeted foliar applications to help get the plant what it needs that it isn't getting from the soil
- A lot of this came with the alfalfa but I also added probably 125% nitrogen to the soil then I have in the past.
