Frequently asked questions(5)
Phacelia can be sown from April to September. For winter green manure, sow in late August — early September. For summer soil improvement — in April-May. Seeds germinate at temperatures of 5-6°C.
Cut phacelia during flowering (approximately 50-70 days after sowing), when the plant is richest in nutrients. Incorporate green mass into soil to a depth of 15-20 cm. After 2-3 weeks, the soil will be ready for sowing the main crop.
Phacelia prefers moderate moisture. Water regularly in dry weather, but avoid overwatering. With sufficient rainfall, additional watering may not be necessary.
Phacelia attracts beneficial insects (bees, bumblebees, wasps), which improves pollination of vegetable crops. As a green manure, it suppresses weeds, improves soil health, improves its structure, and increases fertility. The plant also helps fight pests and diseases.
Phacelia is an annual plant and does not overwinter. For winter green manure, sow in late August — early September. The plant will emerge in autumn, overwinter as young plants, and be ready for incorporation in early spring.
