Citrus is a sub-tropical plant and most varieties are not cold tolerant.
Regardless where you live, it may be necessary to protect your tree during freezing
conditions. While they may be able to survive temperatures of 28ºF for several hours,
most will not for a signicant duration. In USDA zone 7 and lower (north), they usually
will not survive in the garden and are best left in a moveable container so you can
protect them against the elements. In USDA zones 8 and higher (south), you may be
able to leave them outside year-round, protecting them during extreme cold periods.
It is best to water thoroughly regularly, letting the soil dry between watering.
Do not let them stand in water. Citrus like sunlight year around.
If growth stalls, it may be necessary to shift your citrus plant to a larger container.
Fertilize every 4 months or so with a citrus fertilizer of your choice.
If you think your tree has a disease or other problem, contact your local
county extension agent for a diagnosis.
