The Nutritional Value of Old Pumpkins
Pumpkins are a nutrient-rich food source, and even when they are past their prime, they can still provide valuable nutrients for your garden. The flesh of old pumpkins is rich in:
- Carbon: A key component of soil organic matter, carbon helps to improve soil structure, increase the water-holding capacity, and support the growth of beneficial microorganisms.
