Strengthening the management of strawberries in spring is crucial for achieving early maturity, superior quality, and higher yields. To ensure optimal growth, attention should be focused on the "five key timings."
First, remove the cold cover promptly. Strawberries are temperate plants that begin root activity when the soil temperature reaches 1–2°C. Once temperatures rise to around 5°C, it's time to take off winter protection materials and clear away leaves and debris. After covering with mulch film, seedlings need hardening off to prevent frost damage in early spring.
Second, loosen the soil and manage seedlings timely. Spring cultivation requires regular soil aeration to raise soil temperature. The depth of cultivation should be moderate, avoiding damage to the roots.
Third, apply fertilizer at the right time. As spring progresses and temperatures rise, strawberries start to grow actively. Timely top-dressing can boost the number of effective flower clusters and improve fruit set rates. Since strawberry roots are shallow and sensitive, use urea and compound fertilizers in controlled amounts—typically 3–6 kg of urea and 10–15 kg of compound fertilizer per mu. During fruiting, foliar sprays of 0.2% potassium dihydrogen phosphate can significantly enhance yield and fruit quality.
Fourth, thin flowers and fruits properly. Each new stem usually produces 10–30 flower buds. Too many buds can drain nutrients, leading to weak plants and smaller or deformed fruits. Therefore, retain 2–3 inflorescences per plant and 3–5 fruits per inflorescence to ensure better fruit development.
Fifth, manage pests and diseases effectively. Common threats include leaf spot, gray mold, powdery mildew, bud blight, viral infections, aphids, spider mites, and underground pests. Regular monitoring and timely intervention are essential to maintain healthy crops.
By following these five key practices, growers can significantly improve the health and productivity of their strawberry plants during the critical spring season.
