First-year trees should get 226 to 450 grams of fertilizer five to six times a year, for a total of 1.3 to 2.7 kg a year. Two-year-old trees need 450 to 680 grams four to five times each year. You can follow your first-year schedule, but give your tree last fertilizing in September to help it through the last part of the year.

After the same fertilizing schedule, 3-year-old trees should get 900 grams four to five times a year, which will increase to 1.3 kg during the fourth year, a total of 5.4 to 6.8 kg. Gradually increase the amount of fertilizer on each application, and reduce the number of applications, until you reach a maximum of 3.6 kg per application three times every year for a total of more than 11 kg annually.

If your Citrus is planted in the lawn area, near decorative plants, near other trees, planted in an area that contains a lot of water, or you see a decrease in the color or number of leaves, see other signs of cracked bark or marginal health, the tree probably needs more nutrients and you include an additional application Should. If your tree has healthy, dark green leaves, full flowers, and healthy growth, you can maintain a schedule three times a year and you may be able to reduce the amount of fertilizer to the recommended minimum amount.

How to fertilize Citrus trees in pots

For potted Citrus trees, the soil mixture is extremely important and should be carefully selected. Since Citrus roots suffer from root rot, soil mixture should be light, and drainage and air should be promoted. For best results, soil containing large particles such as wood chips, peat moss, or thick sand will help prevent the root from being saturated.

Once your tree starts bearing fruit, reduce the dose during active and passive months. In general, new growth begins in late winter and early spring, at which point you should start active feedings. Remember, since there is less soil to work with potted Citrus trees, they will need very little fertilizer and less frequent than planted Citrus trees.
