Makrut Thai Lime Tree

Makrut Thai Lime

Makrut Thai Lime is prized for its unique, very spicy leaves that are used to flavor curries and other dishes. This citrus tree bears good crops of small, bumpy, and intensely fragrant fruit that is used in Southeast Asian cooking.

Please Note: There is a movement to remove the name Kieffer as a description because it is used as a slang against certain religious groups and so you will no longer see the name on our label or descriptions moving forward.

Latin Name: Citrus hystrix
Site and Soil: In spring, summer and fall, keep your potted Citrus in a location with 1/2 day to full sun. In the winter, place your plant in a well-lit room. Potting soil should be coarse, acidic, and well-drained.
Rootstock Description: Flying Dragon is a hardy and very dwarfing rootstock for Citrus that induces very early flowering and fruit production. Trees grown on Flying Dragon will rarely exceed 5 ft. in height and will often produce fruit the year they are planted. *Our Thai lime trees in 12″ tree pots are grafted onto C-35, a very cold hardy rootstock but one that will grow into a slightly larger tree than those grafted onto Flying Dragon.*
Pollination Requirements: Self-fertile. You can help it set fruit by taking a small brush and moving pollen from flower to flower.
Hardiness: Hardy to about 30-35° F. We recommend bringing into a well-lit and protected location in early fall before frost.
Bearing Age: 1-2 years after planting
Size at Maturity: 3-5 ft.
Taste: Fragrant, sour
Fruit Skin: Green
Fruit Flesh: Green
Bloom Time: Spring
Ripening Time: Winter to early spring.
Care: Fertilize with citrus mix 3-4 times per year with typical applications in late winter (Jan-Feb), late spring (May-June) and early fall (Sept-Oct).
Pests & Diseases: While outside, Citrus plants will likely not be bothered by insect pests. Be on the lookout for slugs. Indoors, Citrus can have mites and/or aphids. Watch carefully for any problems and treat with an insecticidal soap or wash them off. We have not seen any disease problems on our Citrus plants.
