During periods of active growth, make sure you keep the soil evenly moist, but the soil should be allowed to dry slightly between waterings during the winter and other times of low growth. Weeping figs should never be waterlogged or allowed to sit with water in their saucers because the roots will easily rot. They prefer high humidity levels, so wash your ficus leaves occasionally with plain warm water – this will help the leaves breathe and improves their appearance. Mist leaves frequently, especially in hot weather. Use tepid water for this operation.
Healthy plants should be fed every month or two during the growing season, using a liquid fertilizer. Weeping figs can tolerate being slightly root bound, but if the plants will become too crowded, the new leaves that appear will be small and the growth will slow. Repot your tree in late winter or early spring, using a general-purpose potting soil. They will grow in most soils, but prefer the well-drained ones, and are drought-resistant once established.
Plants can be pruned to shape as needed. They will even tolerate hard pruning to reduce their size if necessary, but if you have to prune them so hard just remember to reduce watering levels to severely pruned plants.
The most common problem of weeping figs is leaf drop. They seem to react to almost any stress by shedding their leaves. Over-watering, under-watering, drafts, lack of nitrogen and low light can all be causes of leaf drop. They often shed leaves when moved to a new location or repotted, but If growth conditions are adequate, it will adapt to its new location and stop dropping leaves, then healthy new growth will appear.
You can propagate weeping figs at any season by air layering, or by cuttings that are best taken in summer and using a rooting hormone and provide bottom head. Sow seed at 15-21 Celsius degrees (59-70 F) in spring.
