Sow seeds on the surface of a good, free draining, damp, seed compost. Then lightly cover, 1mm deep with vermiculite or compost. Place container in a propagator or seal inside a polythene bag at a temperature of 21-26?C (70-80?F) until after germination which usually takes 10-42 days.
Transplant seedlings when large enough to handle, into trays or 7.5cm (3in) pots. Ficus benjamina needs careful placement if it is to thrive. Weeping Figs dislike being moved and tend to shed their leaves if repositioned, so it is worth taking care to find the right spot, with plenty of room to grow, from the outset. Position in a bright room, away from cold draughts and radiators, with a constant temperature of between 16°C (60°F) and 24°C (75°F). Ideally Weeping Figs should receive a good balance of sun and shade, but avoid the direct glare of the sun.
