Growing Big Pumpkins
Proper fertilization, seed spacing and the use of plastic mulch and floating row covers are important to producing big pumpkins in your garden.

Always apply lime and fertilizers based on soil test recommendations. Giant pumpkin vines require approximately 2 pounds nitrogen (N), 3 pounds phosphorous (P) and 6 pounds potash (K) per 1,000 square feet of growing space.
