They are often used as good materials for decorating flower beds and arranging rock gardens, and can also be potted or watered for indoor viewing. Let's take a look at the breeding methods and matters needing attention of saffron.

Growth habits of saffron

Saffron is native to southern Europe and is commonly cultivated in various parts of China. For autumn planting bulbous flowers, like cold, cool, humid and semi-shady environment, cold-resistant, suitable for well-drained, humus-rich sandy loam, pH 5.5-6.5. The corms dormant in summer and root and sprout leaves in autumn. It blossoms in late October and the flowers are closed day and night.

Propagation methods of saffron

The main results are as follows: 1. Saffron is generally carried out from August to September, and the mature corms have several main and lateral buds, which expand from the base of the leaves to form new bulbs, dig out the corms after withering in summer and store them in shade according to grades. The early planting time is beneficial to the formation of strong seedlings, and the big balls are planted separately from the small ones.

2. Sowing: crocuses need artificial pollination before they can get seeds. After seeds are mature, they are sown in the open field seedbed or pot. The sowing density should not be too high, and the plants need long balls. Generally, they can not be dug within 2 years. From seed sowing to plant flowering, it usually takes 3 to 4 years.

Culture methods of saffron

1. Planting: saffron culture chooses fertile and loose soil rich in humus, and the selection of seed balls must choose strong balls that are large and full, without mildew spots and disease spots. In autumn, seed balls are planted in flowerpots, one plant in principle, but according to the size of plants and flowerpots, 4 plants can be planted in a pot, and the soil can be covered with 5 cm after planting. Within a week after planting, place the flowerpot in a cool and ventilated place and move it to a brightly lit place for maintenance for a week.

2. Watering: crocuses are usually planted in autumn and are growing in winter and spring. The climate is cold and dry and needs proper watering. Seedlings emerge about 20 days after planting, and water is poured once before emergence to facilitate seedling emergence. Pour antifreeze water before winter to increase the temperature of the soil. Water is watered once in mid-April to reduce the harm of dry and hot wind. Pay attention when watering, do not pour ice water when the temperature is low, the temperature of the water is the same as the room temperature, lest the basin soil freezes and affects the plant growth.

3. Fertilization: before planting saffron, a sufficient amount of base fertilizer should be added to the basin soil, such as cake fertilizer, stable fertilizer, burning soil, plant ash, chicken and duck manure, etc., as well as some superphosphate. After rooting, the thin liquid fertilizer with balanced nitrogen and phosphorus can be applied every 10 days. Fertilizer application avoid excessive concentration of fertilizer, so as not to cause excessive growth of leaves and affect the growth of flower buds. The balanced available fertilizer of nitrogen, phosphorus and potassium should be applied once or twice after flowering in October to facilitate the growth and development of the corm.

Points for attention of saffron

1. Variety selection: saffron usually blossoms in winter and spring, and flower friends can choose different varieties according to their needs. It is suggested that the spring flowering varieties should be selected, the spring environment is relatively better, and the bulbs are stored in time after flowering, and the flowering time is longer.

2. Flowerpot size: saffron planting pots should choose mud pots of 15cm to 20cm or plastic pots with good air permeability. Each pot should plant 4 to 6 big balls, which should be planted from September to October. When you can also use a small basin, 3-5 cm black plastic basin, one basin and one ball.

3. Bulb storage: the aboveground branches and leaves of saffron turn yellow gradually from April to May. The bulb can be dug out of the basin and stored in a gauze bag, stored in a place with less light, shade and ventilation, keep indoor dry and can be replanted in autumn.
