During the growth period, watering should be done with small amounts of water frequently. In spring and autumn, water once every 2-3 days, and in summer, water every day. Spray water on the leaves in the evening to maintain a high humidity.

Fertilization: During the growth process, 20% decomposed bean cake water is generally applied once a month;

Stop applying nitrogen fertilizer during the flowering period and apply 0.5% superphosphate or decomposed chicken and duck manure water once every half a month;

After the flowers fade, apply 30% decomposed bean cake water as top dressing to replenish the nutrients consumed by flowering.

Stop fertilizing during hot summer weather. Apply compound winter fertilizer again in late autumn to enhance the plant's resistance to cold.
