The Red-leafed rock fig is a semi-deciduous tree with a deeply grooved stem and a low, spreading crown. It can grow as a rock-splitter or as a strangler on other trees - a feature which can be utilised when styling as a bonsai.
The bark on young branches is smooth and green, but turns grey on older branches, peeling off in small, thin flakes.
The leaves are simple, smooth and glossy green; coppery red when young.
Figs are borne singly or paired in leafaxils from June to December; green and turning purplish red when ripe.
The habitat is rocky outcrops or hills in woodland or forest.
The Red-leafed Rock Fig makes a very successful container plant and looks stunning in Spring with its new red leaves.
The Red-leafed Rock Fig as a Bonsai:-
It can be trained in various bonsai styles, but looks best when grown in association with rocks.
Cultivation - grows well from cuttings or truncheons. Cuttings can be made from either soft or hard wood. truncheons must be left in the shade for a few days prior to planting. Planting in river sand promotes root development and prevents fungi from attacking the tip of the- truncheon or cutting.
The Red-leafed Rock Fig is a fast grower and can withstand cold, but should be protected from frost for the first two years.
Growing mix - likes a light, friable growing medium. Will flourish in the club soil mixed with equal quantities of river sand.
Watering - moderate in summer but keep relatively (not completely) dry in early spring to enhance the colour of the new leaves.
Feeding - from spring to autumn using a liquid fertilizer. Do not feed in winter.
Repotting - best in spring. If the tree is planted on or in a rock, the tree and rock should be repotted together as a unit
Pruning - will respond well to frequent pruning and can show reasonable leaf reduction.
Position - can take full sun in summer and only needs winter protection in case of a really severe frost. Will do
reasonably well indoors.
Diagnostic features of all Ficus species are:-
the milky latex in all parts
the presence of stipules covering the growth tips.
