Description

The lemon is the most well‑known citrus pot plant, an evergreen shrub that bears flowers and fruit almost year‑round. Its intense fragrance and sour, juicy fruit make it a classic for terraces and balconies. In the DACH region it is not winter‑hardy and requires a bright, frost‑free winter location. Robust varieties such as 'Meyer' are somewhat more tolerant and fruit more abundantly.

Care instructions

Move the lemon outdoors fully sunny from mid‑May (week 20) after the ice‑free period, to a warm, wind‑protected spot. Water regularly with low‑alkali water and fertilise weekly with citrus fertilizer from April to September. Over‑winter it in a bright place at 5 to 12 °C and water sparingly thereafter. Prune in spring (March, week 11) to shape a airy canopy.
