Is it better to plant water lilies in soil or water?

Water lilies are born in ponds and lakes, and like sunny, warm and humid environment with good ventilation. Water lily is a perennial aquatic herb, and hydroponics is better. In hydroponics, a water tank or a glass fish tank is selected according to the plant shape, the container is cleaned, disinfected with potassium permanganate solution, placed in a dry and ventilated place, and covered with sludge with a thickness of 1/2, which is beneficial to the root growth of seedlings and improves the survival rate.

Select water lily seedlings with strong stems and branches, wash them with clean water, insert them into prepared containers, and inject rootless clean water, preferably river water or well water. If you want to use tap water, you need light for 2-3 days to volatilize chlorine in the water.

Water lilies cultured in water will go into dormancy at low temperature in winter. The container can be buried in the soil or put in a large pool. In addition, water lilies are prone to leaf rot, anthracnose and other diseases during their growth, and suffer from aphids. When infected, thiophanate methyl was selected for spray control and dimethoate EC for spray control.

How to maintain fresh-cut sleeping lotus

1, bottle hydroponics

Fresh cut water lily flowers can be kept in hydroponics. Choose fresh cut flowers with good growth and stout stems, wash the roots with clear water, then obliquely cut the base of the flower branch according to the height of the vase, so that the bud is 10 cm away from the bottle mouth, then insert the trimmed fresh cut water lily into the vase and pour two-thirds of the clear water.

2. Change the water regularly

Water lilies have higher requirements for water quality. In the process of hydroponics, hydroponic solution belongs to still water, and the roots of water lilies will constantly secrete toxic substances, which will pollute the water quality and lead to poor plant growth. Therefore, in hydroponics, the water should be changed every other week, and the roots and vases should be cleaned to avoid breeding bacteria.

Step 3: Sunlight exposure

Water lilies are plants that like light. Even if it is hydroponic, it needs to be placed in direct sunlight, which is conducive to the blooming of flower buds and bright colors. However, in the process of hydroponics, water lilies have poor sunlight resistance. When the light is too strong at noon, move them to a place with astigmatism to avoid the water lily withering because of the rapid evaporation of water.
