Lemon Tree – Feeding An Indoor Lemon Tree.
Indoor lemon trees can be both decorative and productive, but they need consistent care to stay healthy and produce fruit. Follow these simple tips to keep your plant thriving year-round:
Feeding
-
Use a balanced citrus fertiliser or liquid tomato feed every 2–3 weeks from spring to early autumn.
-
Reduce feeding to once a month in late autumn and winter when the plant’s growth slows.
-
Always water before feeding to prevent root burn.
-
Flush the pot with plain water every 2–3 months to clear any salt build-up from fertilisers.
Watering and Drainage
-
Ensure good drainage — never let the pot stand in water.
-
Use a saucer or tray only if it allows excess water to drain freely.
Light and Temperature
-
Place in a bright spot, ideally near a south- or west-facing window.
-
Supplement with LED grow lights during the darker winter months if natural light is low.
-
Maintain temperatures between 18–24 °C during the day and protect the plant from cold draughts.
Humidity and Air Circulation
-
Increase humidity by misting the foliage or standing the pot on a tray filled with water and pebbles (ensure the pot is above the water line).
-
Rotate the plant weekly to encourage even growth on all sides.
Pruning
-
Prune lightly after the main spring growth to keep a tidy shape and encourage the growth of fruiting wood.
With the right routine and conditions, your indoor lemon tree can produce fragrant blossoms and fresh lemons — even in the UK climate.
