A bi-generic hybrid, Citrus aurantifolia x Fortunella sp. An evergreen frost tender tree. It is in leaf all year. The flowers are hermaphrodite (have both male and female organs. Edible fruit - raw or cooked. The fruit is about 3-5cm in diameter, very acid, it can be used in all the ways that lemons are used.
The plant prefers light (sandy), medium (loamy) and heavy (clay) acid, neutral and basic (alkaline) soils. It cannot grow in the shade. It requires moist soil. Requires a position in full sun in a fertile well-drained but not dry soil. Prefers a moderately heavy loam with a generous amount of compost and sand added and a very sunny position. When growing plants in pots, a compost comprising equal quantities of loam and leafmould plus a little charcoal should produce good results. When watering pot plants it is important to neither overwater or underwater since the plant will soon complain by turning yellow and dying. Water only when the compost is almost dry, but do not allow it to become completely dry.
The seed is best sown in a greenhouse as soon as it ripe after thoroughly rinsing it. Sow stored seed in March in a greenhouse. Germination usually takes place within 2-3 weeks at 13C. Seedlings are liable to damp off so they must be watered with care and kept well ventilated. When large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for at least three growing seasons before trying them outdoors. Plant them out in the summer and give them some protection from the cold for their first few winters outdoors.
Cuttings of half-ripe wood, July/August in a frame. Layering in October.
