Second, watering, the four seasons begonia likes warm conditions, so during the growth period, it should be watered according to the plant growth and temperature changes. Water less during germination and keep the pot soil slightly dry. If it is too wet, it will lead to rotten roots. Water the plant every two days during the growing season, and spray water around the plant frequently to increase air humidity. Another thing to note is that when watering, do not pour the leaves and stems from the top, but pour along the edge of the flowerpot, otherwise the stems and leaves are easy to rot.

Third, fertilization, four seasons begonia in the growth period should be based on the plant leaf color and leaf growth quietly applied fertilizer, can not fertilize too much, otherwise it will lead to excessive leaf growth, affecting flowering. Appropriate amount of phosphorus and potassium fertilizer should be applied before flowering to improve flowering quality.

Fourth, when winter comes, dig up the bulb and hang it in a dry and ventilated place or put it in a warm place indoors for winter.

Fifth, disease prevention, four seasons Begonia in high temperature dry period, easy to occur root rot and stem rot. At the initial stage of discovery, watering should be controlled in time, and carbendazim should be sprayed for control. Continuous use for a period of time visible efficacy.

Sixth, winter and summer management, four seasons begonia winter, summer due to the impact of temperature, growth is relatively slow, need to strengthen fertilizer, water management.

Tenth, the flower pot of the four seasons begonia, usually should be placed on the balcony or courtyard semi-shade maintenance, must not let direct sunlight come in, and pay attention to ventilation, the four seasons begonia planting half a month after the application of a decomposed fertilizer, after the growth period, every 20-30 days to apply a light fertilizer, winter should be moved indoors placed in sufficient sunlight, and the minimum temperature should not be lower than 10 degrees.

precautions

1 fat. Spring and autumn four begonia growth period need to master the principle of thin fertilizer application, mainly apply decomposed organic thin fertilizer water or inorganic fertilizer soaking solution without peculiar smell. In the seedling growth stage, more nitrogen fertilizer can promote the growth of branches and leaves; in the bud flowering stage, more phosphorus fertilizer can promote more buds, more flowers and bright colors. If there is no fertilizer, the four seasons begonia plants will wither or even die.

2 water. Spring and autumn four begonia growth period soil needs to contain more water, watering should be timely, keep moist.

(3) Summer and winter management. Summer and winter due to temperature, slow growth, need to strengthen fertilizer, water management. In the summer high temperature season, to avoid strong direct light and cooling measures, create a small environment below 30℃ conservation, keep the pot soil dry and wet suitable, too wet easy to rot roots, too dry leaves will wilt, as long as slightly wet can; if too much fertilizer during this period, will cause stems and leaves tender or rot disease. As long as the temperature in winter is kept above 10℃, it can safely overwinter. In summer and winter management, if the temperature can be controlled below 30℃ and above 10℃, the watering is appropriate, the fertilizer is appropriate, the plant must be healthy, and the flowering can be achieved all the year round.
