Winner of the RHS Award of Garden Merit.
Hardy Shrub / Tree
Flowers: Mid to late summer
Height: 5m if not pruned back
Position: Sun and well-drained soil
Packet of 30 or 100 seeds
Pre-sowing Treatment: Soak the seeds in water which starts off hand hot for 24 hours or until the seeds start to swell.
Sowing Instructions: Sow at any time of the year. Sow thinly in pots or trays of moist, good quality seed compost, eg John Innes, just covering the seeds with a sprinkling of sieved compost or vermiculite. Seal in a polythene bag or place in a propagator and maintain an optimum temperature of 18-21C. Germination should take place in 30 - 90 days. Gradually increase ventilation as the seedlings emerge by opening the bag or propagator vents. Germination can be erratic with some seedlings emerging before others, hence the need to sow the seeds thinly to avoid disturbing the compost too much when potting up.
Growing Instructions: When the seedlings are large enough to handle, pot up into small pots and grow on in slightly cooler conditions in plenty of light but shaded from direct sunlight, re-potting as necessary. The young trees will probably be large enough to plant out in the garden at 1 to 2 years old. Rhus like a sunny position in fairly well drained soil.
