Generally, it's cold in winter and spring, so water once in 7-10 days. In spring, when the temperature rises, we should wait until the soil in the basin dries quickly before watering. And the principle of watering is not to dry or not to water, watering to be fully, and then to be fully dry. The Christmas Cactus likes half shade, so after spring leaves the room as far as possible puts in the leeward sunny place.
From spring to summer, thin liquid fertilizer can be applied once every 10-14 days, and then transferred to the ventilated shade place for maintenance. In summer, fertilization should be stopped and water should be less in high temperature period, because the growth of crabmail is stagnant at this time, but water can be sprayed 2-3 times a day, if water is too much at this time, it will lead to rotten roots.
Although there is no need to water during the pregnancy stage, water should be sprayed frequently to keep the stem and flower bud moist. The temperature of flowering period should be 10-15 ℃, the short-term dormancy period after flowering should be less water and stop fertilization, cut and trim the remnant flowers, wait for the stem to grow new buds, and then carry out normal water application.
In autumn, more water should be applied to Christmas Cactus, especially fertilizer and water should be supplied continuously. Liquid fertilizer or compound fertilizer can be applied once a week, and one or two more times of phosphate fertilizer should be applied before flowering. During this period, if you want to be beneficial to the formation of flower buds and the bright colors of flowers, you should provide sufficient nutrients. Fall can be placed in a sunny place, can promote flower bud differentiation.
