How and When to Fertilize Strawberries for the Best Harvest:
Test the Soil First – Before fertilizing, check the soil pH (ideal is 5.5–6.5) and nutrient levels to avoid over-fertilization.
Use Balanced Fertilizer at Planting – Mix a balanced 10-10-10 fertilizer into the soil when planting to support early root and leaf growth.
Apply Nitrogen After Renovation – For established strawberry beds, apply a nitrogen-rich fertilizer right after harvest or bed renovation (typically mid-summer).
Avoid Spring Overfeeding – Don't apply high nitrogen fertilizer in early spring; it encourages too much leaf growth instead of fruit production.
Choose Slow-Release Options – Use slow-release or organic fertilizers (like composted manure) to provide steady nutrients over time.
Water After Fertilizing – Always water the plants after applying fertilizer to help nutrients reach the roots.
Mulch to Lock In Nutrients – Use mulch (like straw) to reduce nutrient loss and keep the soil moist.
Avoid Fertilizing During Fruiting – Do not fertilize when the plants are flowering or fruiting to prevent poor fruit quality.
