1. Pot soil: There are many options for cultivating radish flowerpots, such as ceramic pots, clay pots or plastic pots; The soil has strong air permeability and drainage, so as to avoid water accumulation in the basin soil. Cultivation can be mixed with humus soil, garden soil, river sand and perlite.
2, moisture: green radish is suitable for growing in a humid environment, to keep the soil slightly moist, there can be no excess water in the flowerpot. Water every 2-3 days in spring and autumn according to the situation; Water every day in summer or once in the morning and evening, and spray water on the leaves at any time to increase humidity; Water can be poured once every 3-5 days in winter, and the water temperature should be similar to room temperature, otherwise it will be frostbitten.
3. Lighting: Under normal circumstances, it is best to let it be illuminated by scattered light instead of strong direct sunlight, and it should be kept in a well-ventilated place. If the indoor culture light is not good, bask in the sun every 10 day, otherwise it will easily grow poorly in the dark for a long time. If you breed outdoors, do a good job of shading, especially in summer, and don't directly receive light.
4. Fertilization: Generally, the radish is fertilized with organic fertilizer, and more fertilization is needed in the peak season. Topdressing is generally based on nitrogen, phosphorus and potassium fertilizer. Do not fertilize in winter. Usually apply fertilizer frequently and thinly. If the amount of one-time fertilization is too large, it will burn the roots.
Second, matters needing attention
1, change water frequently during hydroponics, 1-2 days, and once a week after new roots grow.
2. Always observe the growth of root system in hydroponics. If there are rotten roots, clean them in time, and then clean other roots. If necessary, use diluted potassium permanganate solution to eliminate poisoning.
If the green radish grows densely, it should be trimmed properly.

Cutting propagation method of radish
1. Selection and treatment of cuttings: the cuttings should be semi-lignified branches with strong growth and no diseases and insect pests, cut into 10- 13cm long, cut into oblique corners at the lower incision, leave 2-3 leaves at the upper end, and cut off half of the leaves to reduce water evaporation and facilitate the survival of cuttings.
2. Cutting substrate: the cutting substrate requires loam or sandy soil, which has loose air permeability, good drainage and high humus content, and vermiculite is the best, so that it can take root quickly and has high survival rate. Disinfect the soil with 2% formalin or 5% potassium permanganate before insertion.
3. Cutting method: quickly immerse the lower end of the prepared cutting into ABT rooting powder or indolebutyric acid, then insert it into the prepared substrate, bury it in the soil 1/2, pour water to make the cutting closely contact with the substrate, and then cover it with plastic film.
4. Post-insertion management
(1) Pay attention to keep the soil moist and the air temperature high after insertion. The soil humidity is about 50%, and the air humidity is 80%-90%.
(2) At the initial stage of cutting, the shading degree of the shade shed is kept at about 80%, which can not only prevent direct sunlight, but also ensure enough scattered light, which is beneficial to photosynthesis and rooting of the cuttings with leaves.
(3) After the above treatment, the roots basically take root after 20 days, and the film can be uncovered to add luster. At the same time, pay attention to foliar spraying and shading in sunny days in summer, pay attention to cold protection in winter, and move pots for normal management about 10 days after rooting.
