What to Do When Kumquat Tree Leaves Dry Up? Find the Cause and Apply the Right Remedy

1. Overwatering

One likely cause of its dried-up leaves is watering too much. If there is too much water in the pot, the leaves will turn yellow and wither. In daily care, be careful not to water too heavily, otherwise the roots cannot breathe well and will rot. The best approach is to let the soil dry out completely before watering again; this is good for root growth and prevents the leaves from drying up. Normally, water more in dry weather and drain in the rainy season, otherwise the boron in the soil will be lost.

2. Poor Soil

If the soil it is planted in is not of good quality and does not meet its needs, it will not have a good growing environment, and the leaves will also dry up. If the soil is compacted, water will find it hard to penetrate into the deeper layers of the soil, the roots at the bottom cannot absorb water and nutrients, and the leaves will lose water and gradually wither.

At this point, you should use a loosening tool to gently loosen the soil, just enough to give it a little aeration. Loosening the soil moderately can make it more breathable, improve drainage, and benefit leaf growth. Normally, add more livestock urine and manure, and about every ten days use some liquid fertilizer to improve the soil, increase nutrients, and make sure the leaves get sufficient nutrition.

3. Pest and Disease Damage

If the cause is pest or disease damage, the leaves will also become diseased and then wither. You can carefully observe the condition of the leaves to see whether there are pests. If there are pests, use insecticide; if it is a disease, use antibiotics or similar medication. If not controlled in time, the pests will eat into its roots, bite and damage the root bark, and nutrients and water cannot be transported to the leaves in time, so they will wither and fall.
