Nurturing Your Pumpkin Plants

Nurture your pumpkin patch by fertilizing the soil weekly throughout the growing season.

Since you will also be watering thirsty pumpkins regularly (at least 1-inch of water per week), using a liquid fertilizer is ideal because the roots of pumpkins can easily absorb water-soluble nutrients.

Pumpkins thrive when you adjust the fertilizer for their growing stages.

Nitrogen (N) should be plentiful during the beginning of the season to stimulate growth, but too much can burn the roots.

When flower buds emerge, ample phosphorus (P) will promote plentiful blooms and fruit development.

Potassium (K) helps to generate healthy fruit, but too much encourages the fruit to grow so quickly it might split its skin. 

To get the right balance of nitrogen, phosphorus, and potassium for your pumpkins, it is recommended to use either a 5-10-5 or 15-15-15 fertilizer.

It can sometimes be tricky to find the right N-P-K combination in just one fertilizer, and you might also consider supplementing with organic compost to add valuable micronutrients to the soil.
