Proper care of the lemon tree

Does a lemon tree need a lot of water?

As subtropical plants, lemons need regular water supplies. Regular watering, daily on sunny days, ensures good growth. However, the plants do not tolerate standing with their roots in water for long. Cover pots and deep saucers should therefore be checked regularly for residual water. The right time for watering has come when the substrate has already dried on the surface.
