1. Compost: Compost is a rich source of organic matter that is loaded with nutrients like nitrogen, phosphorus, and potassium. Mix compost into the soil before planting your strawberry plants, or use it as a top dressing around established plants.
2. Worm Castings: Worm castings are a nutrient-rich fertilizer that is produced from the digestive processes of earthworms. They contain high levels of nitrogen, phosphorus, potassium, and other micronutrients that are essential for healthy growth and fruit production.
3. Fish Emulsion: Fish emulsion is a liquid fertilizer that is made from the remains of fish after they have been processed for consumption. It is high in nitrogen, phosphorus, and potassium, and is easily absorbed by plants. Dilute the fish emulsion with water and apply it to your strawberry plants every few weeks during the growing season.
4. Seaweed: Seaweed is another excellent source of nutrients for your strawberry plants. It is high in potassium, calcium, and magnesium, and contains small amounts of nitrogen and phosphorus. Seaweed can be used as a liquid fertilizer or as a dried, crushed powder that can be added to the soil.
5. Manure: Manure is a natural fertilizer that is rich in nitrogen, phosphorus, and potassium. However, it should be well-aged or composted before using it on your strawberry plants to avoid burning the roots with excess ammonia. Apply manure in the fall before planting your strawberries or as a top dressing during the growing season.
