Key steps

  • Meyer lemon, calamondin and kumquat are the citrus best suited to indoor growing (University of Minnesota).
  • Around 18 °C (64 °F) during the day and 3 to 5 °C (37 to 41 °F) less at night; direct sun for part of the day (University of Minnesota).
  • Outdoors in summer, with a gradual transition: shade, then full sun, then shade before bringing it back in (University of Minnesota); the lemon tree is among the least cold-hardy citrus (University of Florida): protect it from frost.
  • In hydroponics: large, very free-draining growing-medium tub (perlite, coco), fertilizer for acid-loving plants at half strength from April to September (University of Minnesota).
  • Without insects, gently shake the flowers to move the pollen (University of Minnesota).
  • Watch for scale insects, whiteflies and mites; washing the leaves regularly keeps them in check (University of Minnesota).
