After the base fertilizer is fully applied, top dressing should be considered. In general, topdressing is not necessary, but it is appropriate in the growth period according to the leaf color and growth. The top dressing is mainly urea and potassium dihydrogen phosphate.
The fertilization amount of potted lotus must be flexible. In addition to the size of the pot, there are also reference soil nitrogen, phosphorus, potassium content.
Generally, for flowerpots with a diameter of 50 cm to 60 cm, in addition to the base fertilizer, 300 grams of organic compound fertilizer should be added.
30 cm in diameter, 40 cm in diameter, 200 g of organic fertilizer. Decrease gradually according to the size of the flowerpot.

Small and medium varieties
For small and medium-sized lotus flowers, the petal layers are relatively large, the flower stems are relatively soft, and they are easy to bend and fall down. When applying fertilizer, the phosphorus fertilizer should be increased appropriately, especially in the flowering period.
The direct potting of lotus flowers on the ground is for dry cultivation, while those in the pool are for pond cultivation. The potassium dihydrogen phosphate should be increased properly during top dressing.
The principle of a small amount and many times should be followed. According to the actual situation, one week or so to observe the lotus growth, can be added appropriately.
Mix urea and potassium dihydrogen phosphate in the proportion of 1:1, mix with clay, knead them into small balls with hands, wrap them into small bags with newspaper and stuff them into basin soil.
