to prune Hibiscus
need some advice on how and when to prune my hibiscus plants, predominantly
Fijian. They are growing very tall and spindly with no leaves/branches
towards the base. Also the leaves are turning yellow and falling
hibiscus are fast-growing and should be pruned to maintain their
shape. Prune in late winter/early spring when the resulting tender
new growth will be safe from cold damage.
For a good-looking plant
try to establish 3-4 main branches. These are then cut back by a
third while the others are completely removed.
A clean cut should be
made just above and angled down and away from an "eye" or node.
(A node is the junction of a leaf and the stem. There is a small
bud in this junction that is activated after pruning.) Cutting above
outward-pointing "eyes" will encourage growth in that direction.
The new growth resulting
from pruning invigorates the plant and will provide a source for
many new blooms.
It will take time for
the plant to produce flowers again as hibiscus flower on new wood.
The upside is you will have more new wood to bloom from.
Hibiscus are gross feeders
so the yellow leaves could be a sign that it needs fertilising.
Be sure to feed them often, preferably every three to four months.
