- Application: Mix into the soil before planting and use as a top dressing during the growing season.
2. Fish Emulsion
Fish emulsion is a liquid fertilizer derived from fish by-products. It’s high in nitrogen, which is crucial for leafy growth.
- Benefits: Quick nutrient release, promotes lush foliage, and is easy to apply.
- Application: Dilute with water according to package instructions and apply every 3-4 weeks.
3. Bone Meal
Bone meal is a slow-release fertilizer rich in phosphorus, essential for root development and flowering.
- Benefits: Supports strong root systems and enhances flowering and fruiting.
- Application: Work into the soil at planting time and reapply mid-season.
4. Blood Meal
Blood meal is a potent source of nitrogen, promoting vigorous leaf growth.
- Benefits: Rapid nitrogen boost, encourages lush foliage.
- Application: Use sparingly to avoid nitrogen burn; mix into the soil before planting or as a side dressing.
5. Seaweed Extract
Seaweed extract is a nutrient-rich supplement that provides trace elements and growth hormones.
- Benefits: Enhances plant immunity, improves nutrient uptake, and stimulates growth.
- Application: Apply as a foliar spray or soil drench every 2-3 weeks.
How to Apply Organic Fertilizers Effectively
Applying organic fertilizers correctly ensures your squash and zucchini receive the nutrients they need. Here are some tips:
