When Is the Best Time to Fertilize Kumquats? A Detailed Guide to the Correct Fertilization Timing

1. When to Fertilize It

You can fertilize it in many seasons, for example in early November to December, in February to March in spring, and in mid-to-late May.

2. Specific Fertilization Methods

1. Apply more winter fertilizer. After picking its fruit, loosen the soil and deep plow, and add some organic fertilizer to help it recover its growth vigor and promote better flower bud differentiation. In November to December, dig a deep trench along the outer edge of the canopy and put in mixed fertilizer. In winter, give it more fertilizer, which can lay the groundwork for bearing more fruit the following year; at the same time, winter fertilization should also be done early, mainly with organic fertilizer.

2. Apply spring fertilizer early. When it sprouts in spring, for example from late February to late March, apply more N fertilizer and P fertilizer, which can make the top of the tree grow thicker and stronger and help the flowering branches become stronger. It can provide enough nutrients to the branch tips to prepare for fruiting.

3. Apply fruit fertilizer skillfully. In mid-to-late May, N fertilizer can be used to replenish the nutrients consumed during flowering, so the fruit will not drop due to lack of nutrients. By July to September, when the fruit has grown larger, nitrogen fertilizer combined with phosphorus and potassium fertilizer is needed, which can provide sufficient nutrients to both the fruit and the autumn shoots.

3. Precautions

When fertilizing it, pay attention to its growth condition, the flower soil, the climate and other conditions, and then determine the amount and method of fertilizer supplementation. In dry seasons, water it first to make the soil moist enough before fertilizing, so the roots can absorb it better. For trees with very good growth vigor, do not apply too much nitrogen fertilizer, otherwise the branch tips will grow too vigorously and the fruit will easily drop.
