Light:

Full sun, a southern exposure, is best however; they will grow in an eastern or western exposure.

Temperature:

Maintain temperatures above 35°.

Humidity:

Preferably 50% or higher; however, they will tolerate low levels with no harm.

Watering:

Bring soil to a state of visual dryness between watering. When watering, thoroughly saturate the soil until a little water trickles out of the bottom of the pot. Growing in a clay pot will help maintain a healthy root system. A slight wilt will do no harm but try not to put plants into a severe wilt.

Fertilizer:

They are moderate feeders so ¼ tsp of fertilizer per gallon of water once a week. Under the fast growth of summer, use ½ tsp of fertilizer per gallon of water once a week. Use a balanced fertilizer such as a 15-15-15 or a blooming fertilizer like 7-9-5. Reduce feeding during the winter.

Pruning:

Prune young plants to encourage branching when young. This will help create a bushy plant that can carry the fruit. The best time to rune is after flowering and when in active growth. You’ll know how much fruit is left on the branches and it allows the plant to get ready for next seasons blooms.

Insects and Disease:

Kumquats are susceptible to mealy bug and scale as well as spider mites under dry, hot conditions. Watch carefully for infestations as well as insects that might be present on adjacent plants. They also are highly susceptible to root disease especially during the winter months.
