Soil
Warm, moist soil, well-enriched with organic matter. When growing dwarf lemons in containers, avoid potting soils that contain wetting agents.
|
Position
A sheltered spot in full sun. In gardens where the temperatures drop below –5 °C grow them in containers that can be moved into a warm, sheltered area during winter.
|
Frost tolerant
Lemons are best suited for sub-tropical gardens, but will survive moderate frosts (-3 to -5°C) if protected when young. In colder areas, don’t worry too much if citrus leaves go yellowish in winter – it is just a sign of them not enjoying the cold. Position them in a warm microclimate such as a north or west facing wall
|
Feeding
In spring and summer, feed with a high nitrogen organic fertiliser. Fertilise more if you see yellowing leaves.
|
Companions
Lemons and other citrus are heavy feeders that resent close company, so companion plants have to be planted a little way away.
|
Spacing
Single Plants: 60cm (1' 11") each way (minimum)
Rows: 60cm (1' 11") with 60cm (1' 11") row gap (minimum)
|
Sow and Plant
Set out new plants in late winter or early spring. Grow in containers of rich compost to keep plants compact and to make it easy to bring plants indoors for the winter. Good drainage is essential. Start small plants in containers at least 30cm (1ft) wide and pot them up a size yearly until they reach mature size.
Our Garden Planning Tool can produce a personalised calendar of when to sow, plant and harvest for your area.

Notes
Prune in spring or summer to shape plants, and watch for thorns. The 'Meyer' lemon is easier to grow than other types.
|
Harvesting
Pick when richly coloured and fully ripe. Picking can continue for several weeks as fruits do not ripen all at once.
|
Troubleshooting
Soft soap sprays can help against scale insects and mealybugs.
