We just want to bring to our readers attention over wintering citrus. All citrus plants need winter protection, and for high qualities batch a frost-free greenhouse (10-15c/50-59f) or airy conservatory is best, however a sunny windowsill in an unheated room is also a good idea. Water the citrus plants moderately in winter and allow the surface to dry out between watering.

It is important to keep the humidity at a high level especially in homes with central heating. Over-watering can cause leaves to yellow and fall.
