Pittosporum is a shrub prized for its shiny leaves and sweetly scented Summer flowers. It is a decorative house-plant for cool rooms and unheated porches.
Germination Temperature (°F)
Water as often as necessary to keep the potting mixture moist but never allow pot to stand in water. During the rest period give only enough water to keep it from drying out.
Feed every 2 weeks during active growth in Spring and early Summer, with standard liquid fertilizer.
Re-pot into containers one size larger every Spring until maximum convenient pot 12 inch is reached. Thereafter, top dress each Spring with fresh mixture.
Dip seeds in boiling water, and sow in well drained seed compost. Pittosporum seeds do not germinate all at once.
Propagate in late Spring from cuttings with a heel about 2-3 inches long, taken from new growth. Trim each cutting below a node, remove lower leaves and dip in rooting powder. Plant cuttings in a 3 inch pot containing cutting compost or equal parts of peat moss and perlite. Enclose in a plastic bag or propagator and keep in medium light. Can also be propagated from seeds.
Give the plant bright light with at least 3 hours of direct sunlight everyday.
Little pruning is needed in Spring. Cut away unwanted shoots, make each cut above a rosette of leaves.
Stand pot outdoors in Summer.
Pittosporum makes a good shrubby indoor plant. It does well in cool Winter temperatures. In Summer it grows rapidly and if kept indoors, may need pruning to keep it to a manageable size.
Pittosporum is ideal for a cool conservatory or greenhouse.
Spray daily if in central heating in Winter or during Summer. In other circumstances spray twice a week. Stand pot on tray of gravel half covered with water. Do not spray when sun is shining on leaves.
Well drained potting compost.
Plants grow mainly by elongation of their cells. Plant cells generally only divide to produce new cells in specialized regions called meristems
