1. How to select blue flax seeds?
Seeds play a vital role in plant growth. When planting blue flax, you must select high-quality seeds for sowing so that the germination rate is higher and the flowers grow more vigorously. Choose plump, intact blue flax seeds. Aged, moldy, damaged or diseased ones must absolutely not be used. Before sowing, the seeds should also be soaked for a period of time to promote germination, helping them sprout faster and better.
2. Seedling cultivation methods for blue flax seeds
1. Sowing time
The suitable temperature for sowing blue flax is 15-20 degrees. Generally, spring sowing time is April to May, and autumn sowing time is mid-to-late September.
2. Material preparation
For planting blue flax, prepare tools and materials such as soil, seeds, a watering device and disinfectant.
3. Soil preparation
Blue flax requires loose, fertile soil with good water retention and drainage. The soil is generally made from garden soil plus humus soil, peat soil and decomposed manure. This mixed formula soil is loose and breathable, retains water and heat, and is fertile, making it very suitable for growing herbaceous flowers.
4. Seed disinfection
Before sowing, in order to increase the germination rate, we need to first wash the seeds with dish soap or laundry detergent, soak them in clean water for 24 hours (25°), put the seeds in the refrigerator to freeze for 24 hours, and after thawing, mix the seeds with fine sand, spread them out to air-dry, and after drying until loose.
5. Soil disinfection
Before sowing, use a 1500-fold potassium permanganate solution to thoroughly water the soil for disinfection. Wait until the water has penetrated before starting to sow.
6. Sowing method
After the soil is disinfected, scatter the blue flax seeds on the seedling soil, then cover with fine sandy soil or vermiculite to 2 times the diameter of the seeds, then cover with transparent glass, and then cover with a newspaper with even print to shade the light. Generally after one week the blue flax seedlings emerge evenly, then remove the glass, and prick out the seedlings after they become strong.
