Landing
Cabbage can be planted both outdoors and indoors. Seeds for seedlings are sown in March-April, and seedlings are transplanted outdoors in May. Planting instructions:
- Recommended planting pattern: 60x50 cm.
- For successful plant growth, it is important to choose an area that receives good sunlight.
- To achieve a bountiful harvest, cabbage is grown in fertile, light loamy or loamy soils that are well-drained, not too dense, and have a neutral pH.
- The best predecessors for cabbage are tomatoes, peppers, potatoes and root vegetables.
- ✓ The soil pH level should be strictly within 6.0-7.5 for optimal nutrient absorption.
- ✓ The soil must contain at least 4% organic matter to ensure adequate nutrition.
Growing and care
The treatment procedures are simple and include the following:
- watering early in the morning or in the evening (rate 8-10 liters per 1 bush);
- fertilizing with fertilizers containing nitrogen, potassium and phosphorus;
- loosening the soil every 4-6 days;
- hilling, creating a mound 20-30 cm in diameter around each plant.
- × Cabbage root fly and flea beetles pose the greatest threat to the Professor F1 hybrid. Regular inspection of plants for signs of infestation is critical.
Reviews
The Professor F1 hybrid cabbage has impeccable flavor and can be grown both outdoors and in greenhouses. It boasts excellent yields and disease resistance. However, pests should be avoided, so preventative treatments are carried out in the spring.
