Water twice a week in Spring and Summer, keeping compost moist at all times but pot must not stand in water. In Winter water only when compost surface has dried out.


Feed every 14 days after the first flower buds appear, with high potash liquid fertiliser. Stop feeding in Autumn and Winter.


Re-pot in early Spring into pot one size larger up to maximum pot size 10 inch. Then re-pot into same size pot annually with fresh soil.


Propagate by 3-4 inch cuttings in Spring and Summer. Use shoots that are neither soft and fleshy nor hard and woody. Seeds are available, but can be more difficult than cuttings.


Plumbago grows successfully only when root ball is compact. Put plenty of broken crocks into bottom of pot. It can be planted directly in borders in rather rich well drained soil.


After flowering cut out weak growths and trim off two-thirds the length of the main stems.


Train plant round a hoop by pushing ends of wire hoop two-thirds down pot. Bend plant stem to one side of hoop gently twist around. Secure plant to hoop with twine, thread it along loosely around stem.


Plumbago grows slowly indoors and must be given ample light and warmth. It is best suited for greenhouses or conservatories. If light is too low, will get spindly and weak and will not bloom. Outdoors place in full light, avoiding midday sun in Summer. Keep in shady position in Winter when dormant. During the rest period give only enough water to prevent the mixture from drying out completely.


It is an ideal plant for growing around a window frame.


Spray with soft tepid water daily in Spring and Summer, avoid flowers.
