Key lime propagation
Generally lime reproduces asexually, by budding in other trees such as lemon, orange, or citron (Citrus medica).
SEXUAL REPRODUCTION FROM SEEDS
– Sow the seeds in warm bed in spring (March-April).
– Germination occurs the 4-6 weeks.
– Repot the plant in individual pots when measuring at least 3 cm.
– Grow in the greenhouse for at least their first winter. Protect from frost.
– Transplant with stake (50 cm. depth) in the final place in late spring or early summer. Maintain spacing of 5-6 meters between each tree so that each plant has all the nutrients from the soil.
