When cultivate lotuses, pond soil or paddy soil rich in nutrients should be used. Such soil can keep water well and fix the root system, to promote the vigorous growth of lotuses. Note that the soil should not be too acidic, otherwise it will affect root germination.
Lotuses like warm environment, have strong high temperature resistance and are not cold resistant. The suitable temperature for them to grow is 22-35 ℃. They will grow normally when the temperature is above 15 ℃. If they are newly sown plants, then they need good temperature control to provide a warm environment for better germination.
Lotuses are plants that like light very much. They cannot leave the light during their growing period. They should be exposed to light for 7 hours every day. Only sufficient light can promote the growth of more flower buds. Whether they are in the pond or in the flowerpot, it is necessary to meet the demand for light and get more sun. If they are under dark environment for a long time, it will lead to shorter flowering period or even no flowering.
Lotuses like fertilizer and consume a lot of nutrients in the peak growth season. They need to be top-dressed in time. When topdressing, it is necessary to apply thin fertilizer frequently, with an interval of 15 to 20 days. It is OK to use compound fertilizer. The nutrient is sufficient to better blossom and the underground lotus root will also grow better. Attention: do not be too close to the root system when applying fertilizer, otherwise it is easy to burn their roots.
Lotuses are easy to be infected with diseases and pests during their growth. The common diseases are leaf blight and putrefaction, and the common pests are aphids. If diseases and pests are serious, they should be treated with medicine in time. In addition, weeds should be removed in time to avoid breeding competition.
