citrus trees need a warm or mild climate zone. As long as frosts are not severe citrus trees will tolerate cool conditions. In cold zones grow only container versions, so when temperatures really plummet, bring them inside a greenhouse or enclosed porch.
citrus need full sun, so place them in the sunniest part of your garden or balcony. Pots must have drainage holes in their base and be elevated slightly off the ground. Water potted citrus two to three times a week, and possibly daily in very hot weather. Apply citrus food in small amounts monthly from august to mid autumn.
