From March to September every year, thin liquid fertilizer was applied to Cycas plants once a week to promote the growth of leaves. After autumn, you can apply fertilizer 1 - 2 times a month in the growing period. Remember to follow the principle of "eat less and eat more".
During the growth period of Cycas, the root should be fertilized once a month, mainly with complete n, P, K fertilizer, and appropriate P, K fertilizer and iron fertilizer. You can use 30-40 g of NPK compound fertilizer, 5-10 g of ferrous sulfate and 10-15 g of potassium dihydrogen phosphate, mix with clear water and spray it directly on the basin soil.
In addition, the mixture of 0.1% zinc sulphate, 0.1% magnesium sulphate, 0.1% ferrous sulphate, 0.2% urea and 0.3% potassium dihydrogen sulphate can be evenly sprayed to the leaves every 7-10 days or so. It is better to start dropping water beads, which can effectively supplement microelements and nutrients to cycas, and can promote more green branches and leaves.
To control the reasonable amount and concentration of fertilization, to ensure the supply of nutrients.
Do not splash the fertilizer solution on the branches and leaves. Wipe off the excess fertilizer solution in time or wash it with clean water, otherwise it will burn the branches and leaves easily, causing the yellow leaves of Cycas.
Every time before fertilization 1, 2 days should stop drenching water, keep basin soil dry, this can promote the infiltration of fertilizer solution, improve fertilization effect
