Optimal Pumpkin Fertilization: Expert Tips for Timing and Nutrient Balance

Pumpkins are heavy-feeding plants that require regular fertilization throughout their growing season. Nitrogen promotes vine and leaf growth, phosphorus encourages flowering and fruiting, and potassium ensures healthy fruit development. It is important to fertilize pumpkins at the right time, starting with compost or balanced fertilizer before planting, then switching to nitrogen-heavy fertilizer during rapid vine growth, phosphorus-heavy fertilizer during flowering, and high-potassium fertilizer when fruits start to form. Conducting a soil test and following recommended rates from the manufacturer are crucial. Coffee grounds can be used as a supplemental feed, and leftover pumpkins can be used as compost or buried to release nutrients into the soil.
