Citrus trees can be rather exacting in their cultural requirements. Lack of fruit set can be due to not enough sunshine, over- or under-watering, or fertilizing problems. Citrus need all day sunshine and are tolerant of a wide range of soil types, as long as the soil is well-draining. They need a constant source of moisture, but it's important not to let the soil get too soggy. Soil that is saturated and then allowed to dry out will affect the performance of your kumquat. All citrus demands high nitrogen levels and should be fed frequently. Choose a fertilzer manufactured specifically for citrus, then read and apply according to fertilizer label directions. If you follow the above guidelines, your kumquat should begin flowering and setting fruit for you. You definitely need to winter your citrus trees over indoors. A bright, sunny window is best. If you can't provide natural sunlight during the winter months, supplement what sunshine you do get with artificial lighting, keeping the light on 14-16 hours a day. You might also aid in pollination by transferring the pollen from one open blossom to the next (use a small artist's paintbrush and visit each open flower the way a bee would). Hope these suggestions help. Best wishes with your kumquat!
