Whether fertilization is needed can be determined according to the growth of the leaves. If its leaves are yellow and thin, it is a sign of lack of nutrition, so it is time to apply fertilizer.
In fact, there is a certain relationship between fertilization and weather. Generally, fertilization can be carried out on a sunny afternoon and not before a rainstorm. Apply less fertilizer when the temperature is low, and more when the temperature is high.
The fertilization of water lily can be determined according to the condition of the soil to see if the soil is poor and what is lacking can be supplemented. If the soil is found to be deficient in nitrogen, phosphorus, potassium and other elements, fertilizer containing these elements should be applied. If it is found that the soil is slightly alkaline, some superphosphate can be applied properly.
Fertilization also depends on the growth of the water lily. If the daily maintenance is good, its growth will be good and less fertilizer can be applied. But if it grows slowly, it should be applied early and more fertilizer.
The fertilization operation should be determined according to the variety and plant size. It has many varieties and different plant types. In principle, more fertilizer should be applied to large plants and less to small plants. Early developed varieties can be applied early, and more fertilizer tolerant varieties should be applied.
The change of seasons will also change the way of fertilization. Generally, the season with the greatest demand for fertilizer is summer, with a large amount of fertilization, while the fertilization in other seasons is relatively less, specifically according to the principle of less in spring and autumn, more in summer and no in winter.
Base fertilizer is a certain amount of fertilizer applied during plant planting. However, because it is not resistant to fertilizer at the early stage of growth, the excessive nutrition may cause the death of the water lily, so in the cultivation, it is not necessary to apply base fertilizer or a small amount of mature liquid fertilizer as the base fertilizer, and attention should be paid not to produce fertilizer damage.
In fact, the most important fertilizing work is topdressing. When it slowly survived and began to grow normally, the substrate in the soil itself was almost consumed. It needs top dressing to ensure its normal growth, otherwise it will make the leaves aging and flowering affected.
When applying fertilizer, you can put a small piece of raw soybean cake into the mud of the water lily, let it ferment slowly, make the root of the lotus root absorb nutrition slowly, or you can use the bean cake or manure that is rotten as top dressing.
Only when fertilization is targeted can we apply right fertilizer, good fertilizer and reduce fertilizer damage.
If the development of water lily is slow and the plant type is small, it is lack of nitrogen. Its stems and leaves are luxuriant, its flowers are less, and the nitrogen fertilizer is applied too much. Root development is poor, flower buds are few, indicating lack of phosphorus. The stem of the water lily is thin and weak, and its disease resistance is poor. All of these are caused by the lack of some elements, so it is necessary to use certain fertilizers. In addition, it is also necessary to apply walnut sized rotten cake fertilizer as top dressing in summer to prolong the flowering period.
If the growth of water lily is poor, it is mostly lack of fertilizer, as long as the appropriate fertilization. But because the plant is small, the amount of fertilizer needed is small, and the fertilization should be moderate. If excessive fertilization occurs, the phenomenon of excessive growth will occur, and the leaves will not bloom. When it is serious, it can make the plant wither.
If you find excessive fertilization, you can change water frequently and dilute the fertilizer.
