What are the maintenance methods of water lilies

Gradually increase the water depth to 20-30 cm and maintain sufficient sunlight and good ventilation.

When planting in a pond, use fertile river mud and base fertilizer, bury the transplanted roots flatly in the mud and then water them. The water depth should be 20-30 cm in spring and about 60-80 cm in summer.

Aphids often cause harm during the growing season, and can be killed by spraying with 2000 times diluted 40% oxydemeton-methyl.

When cultivating in ponds, the pond water should be drained in early spring. Loosen the soil near the rhizomes, apply base fertilizer, add mud, and then water.

From spring to summer, as new leaves grow, gradually deepen the pond water. In summer, keep the water depth at 50-80 cm. In the north in winter, the water depth should be more than 1 meter to avoid damage to the roots and rhizomes. Renew it about 3 years after planting.

For potted plants, around the spring equinox every year, the pots should be repotted and the soil changed in combination with division, and an appropriate amount of decomposed bean cake juice should be applied as base fertilizer and replanted. Then place it in a large water tank or shallow pool, and always keep the water depth at 20-40 cm.
