Things You'll Need:
- Big Max seeds
- Organic matter
- High phosphorous fertilizer
- High nitrogen fertilizer
- Water source
-
Step 1
Plant pumpkin seeds inside 2 to 3 weeks before the last expected spring frost. This is especially important if you live in a cool climate that has a short growing season. Pumpkins need 120 days of frost free growing to reach maturity. If your areas does not have a growing season of 120 days, starting them inside will give them the added time they need.
-
Step 2
Choose a sunny location that receives at least six hours of direct sunlight every day. Pumpkins thrive on sunshine. Pick the sunniest area in your yard for these Big Max pumpkins. The more sun they receive the better they will grow.
-
Step 3
Prepare the soil for the plants by creating a mound of dirt that is two feet in diameter. Add plenty of organic material and mix in well. If you prefer to use commercial fertilizer, this is the time to add the fertilizer. Follow the recommended amount on the package and mix it into the existing soil. Do not use more than recommended as this may burn the seeds or the young roots of your seedlings.
-
Step 4
Create hills 20 feet apart. You will need one hill per plant so plan accordingly. Pumpkins take up a lot of space, but if you want to grow a prize pumpkin, you must allow the plant to vine and must not overcrowd them.
-
Step 5
Plant Big Max pumpkin seeds right in the garden in areas where the growing season is at least 120 days or transplant the seedlings after all danger of frost has passed. Seeds should be planted to a depth of no more than one inch and covered with soil. Plant two to three seeds per hill. You will later remove all but one healthy plant per hill. Tamp down with your hands to settle the seeds and create a firm soil.
-
Step 6
Water the newly planted pumpkins and keep soil moist until seeds germinate. In warm soil, pumpkins germinate in 5 days, but may take up to 10 days is cooler soil.
-
Step 7
Remove all but one plant once your pumpkin plants have grown the first set of true leaves. It may be difficult to remove perfectly healthy plants, but don't be fooled into thinking more is better. To grow a prize pumpkin, you need to allow one plant to a hill.
-
Step 8
Fertilize regularly with a high nitrogen fertilizer for early growth. This will encourage leaf and root growth. Switch to high phosphorous fertilizer just before blooming.
-
Step 9
Water the base of the plant in the evenings whenever the soil is dry. Take care not to get water on the leaves. Pumpkins grow rapidly at night and can use the added water to promote that growth.
-
Step 10
Remove all but one pumpkin per vine once the fruit has reached softball size. Continue to fertilize and water this pumpkin.
-
Step 11
Prune the vine by pinching off the tip and any side shoots when it has reached 20 feet to prevent new fruit from forming.
