    Burpee’s organic fertilizer uses bone meal as its main nutrient source and has a 6-8-0 NPK value. Using this once the growing season kicks off helps the pumpkins grow strong roots and foliage. The nitrogen concentration also helps the vine grow large and make room for more blooms and fruits.

    MasterBlend Tomato & Vegetable Fertilizer

    Fruitful with potassium

    MasterBlend’s fertilizer formula is a 4-18-38 blend, meaning it’s heavy with potassium and phosphorus with minimal nitrogen. It’s a premium mix that helps late-bloomers survive once the cold creeps in for fall. It is better used towards the end of the growing season and helps create an abundance of large pumpkins in your patch.
    Down To Earth Organic Langbeinite Fertilizer Mix

    Potassium-heavy food for the fall

    Down To Earth Langbeinite is a completely natural plant food that has a 0-0-22 NPK value, meaning it’s full of potassium. Other than having 22% potassium, this water-soluble mix is also rich in magnesium and sulfur. The potassium strengthens its roots, hardens its stems, and protects its fruits once the temperature lowers. This also helps your pumpkins avoid disease without damaging your soil’s natural pH.

If you’re lost on what to feed your pumpkins, we’ve got some recommendations.

For those wanting a large yield, focus on a nitrogen-heavy formula like the Miracle-Gro Water Soluble All Purpose Plant Food.
