I bought a pot of flowers called "Yuanbao". How should I raise it? How often is it appropriate to water?

Acer truncatum is native to Mexico. I like warm and dry, I like plenty of light, and I like semi-cloudy. Not strict with soil, drought-tolerant, sandy-loving, not cold-resistant. Potted soil should be mixed with coarse sand or charcoal powder in garden soil to facilitate drainage. Change pots 1 time in March-April every year, and add some phosphate fertilizer at the same time, so topdressing is not needed at ordinary times. The principle of attention is not watering, but watering thoroughly and controlling water in winter. In the growing season, the flowerpot should be placed in a ventilated and light-transmitting place, and the room temperature should be kept at about 65438 00℃ in winter, and sufficient illumination should be given.
