Pumpkin peels are rich in potassium (K), just like banana peels, containing approximately 550 milligrams of potassium per 100 grams. And we know that potassium is vital for plant health, as it promotes flower and fruit development, improves drought resistance, and enhances overall plant vigor.

  • Boosting Fruit Production: Incorporating composted pumpkin peels into your garden soil can significantly increase fruit production in plants like tomatoes, peppers, and pumpkins.
  • Enhancing Flowering: Potassium-rich pumpkin peels are excellent for flowering plants like roses and hibiscus, ensuring a profusion of blossoms.
  • Application: Cut the peels into smaller pieces to accelerate the decomposition process. Use 2-3 handfuls per plant.

  • Improved Nutrient Uptake: Strong roots enable plants to absorb essential nutrients more efficiently from the soil.

Pumpkin peels are rich in key macro and micronutrients like potassium, phosphorus, and magnesium. These nutrients contribute to enriching the soil profile, making it more fertile and conducive for plant growth.

The decomposition of pumpkin peels can improve the soil’s physical properties. It can convert compacted, hard-to-work soil into a more friable, workable medium.

The organic matter from the pumpkin peels helps bind soil particles into aggregates, improving soil structure. Better soil structure increases pore space, leading to improved air and water infiltration rates.

  • Enhanced Soil Fertility: As pumpkin peels decompose, they release nutrients gradually, enriching the soil with essential elements.
  • Reduced Soil Erosion: The organic matter in pumpkin peels helps prevent soil erosion and compaction.
  • Application: Let the peels dry in the sun for 1-2 days until they become brittle. Once dry, grind the peels using a blender or food processor. Use 2-4 tablespoons per plant in 8-10 weeks.

4. Pest Deterrent and Disease Resistance

Nutrient Composition: Pumpkin peels contain compounds like cucurbitacin, which may act as natural repellents against certain garden pests.

  • Pest Deterrence: Placing composted pumpkin peels around the base of plants may deter pests like aphids, cucumber beetles, and squash bugs.
  • Potential Disease Suppression: Some gardeners believe that the presence of cucurbitacin compounds in pumpkin peels may contribute to disease resistance in nearby plants.
  • Application: Take the small pieces of pumpkin peel and scatter them around the base of the plants. The scent and taste of the peels act as natural deterrents to pests like ants and slugs.
