Winter red fruit is a deciduous shrub or small tree of Rosaceae and Malus, which is not resistant to high temperature! If you don't cool down, you will die easily! Personally, if it is higher than 3 5℃ for a long time in summer, you can properly shade and ventilate to cool down. Potted plants can be buried in the outdoor shelter from the wind and sun or put in a cold room at 0℃ to 10℃ for the winter. Before sprouting in spring, the plants should be pruned and reshaped once, and the diseased dead branches, cross branches, over-dense branches and over-flourishing branches should be cut off to facilitate ventilation and light transmission and keep the trees beautiful. 1 to 2 years before germination, change the pots once. Potted soil can be 1 part humus soil and garden soil, 0.5 part coarse sand, and a small amount of hoof pieces or decomposed animal manure can be added as base fertilizer.
