Warm, moist soil, well-enriched with organic matter. When growing dwarf limes in containers, avoid potting soils that contain wetting agents.
A sheltered spot in full sun spring to fall. In winter, plants may be moved into a greenhouse, sunroom, or heated garage.
No. Grow at temperatures above 7°C (45°F). The ‘Bearss’ lime often grown in containers should be brought indoors when temperatures go below 5°C (40°F).
In spring and summer feed with a balanced organic fertilizer. Fertilize more if you see yellowing leaves.
Thyme, Marigold, Borage and Calendula. Limes and other citrus are heavy feeders that resent close company.
Single Plants: 1′ 11″ (60cm) each way (minimum)
Rows: 1′ 11″ (60cm) with 1′ 11″ (60cm) 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 12″ (30cm) wide and pot them up a size yearly until they reach mature size.
Prune in spring or summer to shape plants, and watch for thorns. The ‘Bearss’ lime is easier to grow in containers than other types.
Pick when richly colored and fully ripe. Picking can continue for several weeks as fruits do not ripen all at once.
Grow outdoors in the warmer months to expose plants to heat and pollinators. Soft soap sprays can help against scale insects.
