How to fertilize Cycas revoluta

Fertilization method of cycad

From March to September each year , apply thin liquid fertilizer to the cycad plants once a week to promote leaf growth. After autumn, you can apply fertilizer 1-2 times a month during the growing season. Remember to follow the principle of "eat less and more meals" when applying fertilizer.

During the growth period of Cycas, its roots should be fertilized once a month, mainly with complete nitrogen, phosphorus and potassium fertilizers, and at the same time, appropriate amounts of phosphorus, potassium and iron fertilizers should be supplemented. You can use 30-40 grams of nitrogen, phosphorus and potassium compound fertilizer, 5-10 grams of ferrous sulfate and 10-15 grams of potassium dihydrogen phosphate, mix with clean water and apply directly to the potting soil.

In addition, a mixture of 0.1% zinc sulfate, 0.1% magnesium sulfate, 0.1% ferrous sulfate, 0.2% urea and 0.3% potassium dihydrogen sulfate can be evenly sprayed on the leaves every 7-10 days or so . It is best when water droplets start to drip down. This can effectively supplement the cycads with trace elements and nutrients and promote darker green branches and leaves.

Precautions for fertilizing cycads

It is necessary to control the reasonable amount and concentration of fertilizer to ensure the provision of nutrients for Cycas revoluta.

Be careful not to splash fertilizer on the branches and leaves. Wipe off the excess fertilizer in time or rinse it with clean water, otherwise it will easily burn the branches and leaves and cause the Cycas leaves to turn yellow.

Watering should be stopped 1 or 2 days before each fertilization to keep the soil in the pot dry. This can promote the penetration of fertilizer solution and improve the fertilization effect.
