Mid-March to mid-April is the best time to turn over the lotus root. Premature planting will be affected by cold current, and lotus roots are easy to freeze. The northern region can be covered with transparent agricultural film in case of cold current. The soil should be mushy before planting. When planting, the top end of lotus root is inserted into the mud at an angle of 20 degrees along the basin edge, and the depth of bowl lotus is about 5 cm. Da Lian is about 10 cm deep, with low head and high tail. The tail is half cocked to prevent the tail of the lotus root from entering the water. After planting, put the flowerpot in the sun to make the surface soil slightly crack, so as to facilitate the complete adhesion of lotus root and soil, then add a small amount of water, gradually deepen the water level after the buds grow, and finally maintain a water layer of 3-5 cm. In the early stage of pond planting, the water layer is the same as that of potted flowers, and the lotus leaves are not submerged in the later stage.

At the initial stage of growth, the water layer should be controlled at about 3 cm, and the water is too deep to raise the soil temperature. If you use tap water, you'd better put it in another jar and dry it for a day or two before using it. Summer is the peak of lotus growth, so there is no shortage of water in the basin. After winter, the pot soil should also be kept moist to prevent the lotus root from drying up due to lack of water.

After winter, put the basin indoors or under frozen soil. The area north of the Yellow River should be covered with agricultural film except under frozen soil, and the basin soil should be kept moist all winter.

The fertilizer of lotus is mainly phosphorus and potassium fertilizer, supplemented by nitrogen fertilizer. If the soil is fertile, there is no need to fertilize all the year round. Rotten cake fertilizer and chicken, duck and goose manure are the most ideal fertilizers. Small pots can only be applied half, and large pots can only be applied 1-2 at most. Never apply more, but mix it with the soil. In the vigorous growth period, if the leaves are found to turn yellow and thin, 0.5g of urea per box can be mixed into the mud and kneaded into balls of about 10g, and each pot is applied with 1 granule, which will take effect in 7 days.

Growing habits:

Lotus is an aquatic plant, which likes relatively stable and calm shallow water, lakes, swamps and ponds, and is its suitable habitat. The water demand of lotus depends on its variety. The relative water level of large plant-shaped varieties such as Gulian and Chiba is deep, but it cannot exceed 1.7 meters. Small and medium-sized plant varieties are only suitable for water depth of 20-60 cm. Meanwhile, lotus is very sensitive to water loss. As long as you don't irrigate for three hours in summer, the lotus leaves planted in the water tank will be sluggish. If the water is stopped for one day, the lotus leaves will be burnt and the buds will wither. Lotus is also very fond of light, and it needs a full light environment during its growing period. Lotus is extremely intolerant of shade, so it will show strong phototaxis when it grows in semi-shade.
