Plant your tree directly in the ground or in a container, and water deeply every other day for the first several months to ensure good root development. After that, water only when the top inch (2.5 cm.) of soil is dry – every week or so. Reduce watering even more to once every two weeks in winter.
Limequat trees enjoy full sun, at least 6 hours daily, so place your tree where it can receive as much sun from morning to late afternoon.
Chemical fertilizers for citrus contain nitrogen, phosphorous, and potassium in varying percentages. For instance, an 8-8-8 food is good for young limes that are not yet bearing but a mature fruit bearer will need more nitrogen so switch to a 12-0-12 formula.
Your limequat will not require pruning except for minor cosmetic pruning to remove dead wood in late February to early March, and to remove any new growth from below the bud union. Although a relative of the cold-hardy kumquat, your limequat needs to be protected on the coldest winter nights.
A limequat (Citrus x floridana), as previously stated, is a fruiting tree that is a hybrid between a kumquat and a key lime. It is more cold tolerant than most lime trees, but a little less so than most kumquats. It can usually survive temperatures as low as 22 F. (-6 C.), and it can sometimes survive as cold as 10 F. (-12 C.).
The container should have drainage holes as citrus trees do not like “wet feet” and should be at least 15 gallons (57 L.) (an old whiskey barrel is ideal).
