How to plant cyclamen seeds?

Cyclamen is also known as radish and begonia, rabbit ear flower, rabbit flower, crown, bonspark, petal lotus and so on. Cyclamen is a perennial herb of Primulaceae, which is suitable for planting in indoor flowerpots and greenhouse in winter. Some cultivated species have a strong aroma, while some are light or no fragrance. Let's take a look at how cyclamen seeds are planted.

Growth habit

Cyclamen is warm and afraid of heat and grows best in a cool environment and in a fertile sandy loam rich in humus. More cold-resistant, can withstand 0 ℃ of low temperature will not be frozen. The growth season is from autumn to spring in the second year. The growth temperature is semi-dormant in summer, and the suitable growth temperature in winter is between 12-16 ℃. The promotion of flowering should not exceed 18-22 ℃. The plants above 0 ℃ will enter dormancy. The plants above 35 ℃ are easy to rot and die, and can tolerate low temperature in winter, but the growth is slow, the flower color is dim and flowering is less than 5 ℃. Carbon dioxide supplementation in winter can promote growth and flowering, requiring moist air and sufficient sunshine during the growing period.

Seed treatment

Cyclamen seeds can only be obtained after artificial pollination. The seeds generally mature in May and should be harvested in time. The seed is larger, the weight of a thousand seeds is about 10 grams, and the general germination rate is 85-95%. In order to promote seed germination, seeds can be soaked before sowing, soaked in cold water for 24 hours or 30 ℃ in warm water for 2 hours or 3 hours, then wash the adhesion on the seed surface, wrap it in a wet cloth to accelerate germination, keep the temperature 25 ℃ for 1 to 2 days, and sow seeds after a little germination.

Sowing method

The sowing time of cyclamen is usually from September to October, and you can sow it in an ordinary flowerpot. The sown soil had better be a sandy loam rich in humus and sifted before use. When sowing, first put the soil in the basin and sprinkle it thoroughly with a spray pot. After the water has completely seeped, sow the seeds in the basin at a distance of 1cm to 1.5cm. After sowing, cover the soil with 0.5cm, cover with glass or plastic film to moisturize, and place in the half shade of 20: 22 ℃. When the basin soil is slightly dry, the basin soaking method is used to soak the water, so that the basin soil is often moist, and seedlings can emerge in about 20 days under normal circumstances.

Seedling management

1. Transplanting seedlings: cyclamen seedlings can be transferred for the first time after the leaves are fully unfolded. Ordinary flowerpots and pots and sowing soil can still be used when transplanting seedlings. The distance between seedlings should be about 3 cm. Spray pot should be sprayed with water immediately after transplanting. Keep the seedling pot moist after transplanting. When the seedlings grow out of 3 leaves and the bulbs grow to 5-6 mm in diameter, they should be planted in pots in time and can be transplanted directly with a small pot with a caliber of 9 cm.

2. Transplanting: cyclamen transplanting pot soil is sifted and mixed according to 20% rotten leaf soil, 20% garden soil, 50% fine yellow sand and 10% rotten dung. Small soil balls should be taken as far as possible when transplanting, and make it flat with the soil surface, sprinkle with water after transplanting and put it in the indoor sunshine. After the seedlings resume their growth, they should be watered and fertilized in time, and they will generally blossom in the winter of the second year.
