How to Grow Kumquat (Calamondin)? A Detailed Guide to Cultivation Methods

Potted kumquats are generally purchased by people as Chinese New Year flowers, especially in southern regions such as Guangzhou, where every household places potted kumquats at their door during the New Year period. Today, the editor will take a look with everyone at how to grow kumquats.

1. Soil Requirements

Potted kumquats like loose and fertile sandy soil. If the soil of a potted kumquat is found to be compacted, it should be repotted immediately, as soil that is not breathable or permeable can easily cause root rot. When repotting, the soil can be made up of 4 parts leaf mold, 5 parts sand, and 1 part cake fertilizer.

2. Watering Methods

Kumquats like moisture but dislike waterlogging; too much watering can easily cause root rot. For home care, the timing of watering should be determined according to the home growing environment. In dry spring, spray water on the leaves once a day to increase air humidity. In summer, spray water 2-3 times a day and also spray water on the ground. When watering, avoid water droplets falling on the flowers, which can cause the flowers to rot and affect fruiting.

3. Light Requirements

Kumquats like a sunny environment and should be placed in a sunny spot during care. If there is insufficient light, the plant is prone to leggy growth and will bloom and fruit less. In summer, when temperatures are high and light is strong, the kumquat should be placed in a shaded area. In winter, the indoor temperature should preferably be just above freezing. If the room temperature is too high, the plant cannot get sufficient dormancy, and the following year its growth will be weak and it will easily drop flowers and fruit.

4. Temperature Requirements

Kumquats like a warm and refreshing environment. When the autumn temperature drops below 10 degrees, the kumquat should be moved indoors, and in winter it is best to keep the growing temperature at 6-12 degrees. If the temperature is too low, it is prone to cold damage; if too high, it affects the plant's dormancy and is unfavorable for flowering and fruiting the following year.

5. Fertilization Methods

Potted kumquats require proper water and fertilizer management. When the branches have grown in fully, apply a fast-acting phosphorus fertilizer, such as superphosphate, once to prevent excessive growth of branches and leaves and to promote flower bud differentiation and flowering and fruiting.

6. Pruning Requirements

Pruning is an important technical measure for making kumquats bloom abundantly and bear abundant fruit. To make the tree shape graceful and produce more fruit, before the spring buds sprout, cut off some of the previous year's branches, leaving 2-3 buds on the vigorous ones, and keep 3 pruned 1-year-old branches per plant, which is beneficial for the sprouting of spring shoots. When the new shoots grow to 15-20 cm, pinch off the tips to make the branches full.

7. Pest Control

The branches and leaves of kumquats are often harmed by scale insects, red spiders, and butterfly larvae, among which scale insects are relatively common. The occurrence period is from April to May, and a 1000-fold dilution of acephate can be sprayed; pests can also be brushed off with a small brush.

Potted kumquats have luxuriant branches and leaves and remain green all year round. When they bloom, they give off a clear fragrance, and the white flowers are very delicate. When the fruit ripens, it turns yellow-red. Whether for foliage, flowers, or fruit, they all have a certain ornamental value and are also very common in homes. That is all for the introduction to kumquat cultivation methods, and I hope it is helpful to everyone.
