Hardy Tree (to about -5C)
Height: Up to 10m if not cut back
Packet of 25 seeds
Sowing Instructions: Sow at any time of the year. Sow very thinly on the surface of a moist, peat-based seed compost, eg. Levington in pots or trays. Do not cover the seed. Seal in a polythene bag and place in the fridge or other cold place between 2-5C for 4 weeks. Then, move to a propagator or leave in the sealed bag and maintain an optimum temperature of 20-23C. Germination can be slow and erratic but should occur after 14-90 days. As the seedlings emerge, pot up individually into 8cm pots taking care to disturb the rest of the compost as little as possible.
Growing Instructions: Grow on in cooler condition until late spring when they can be moved to a coldframe or plunged in the pots up to their rims in a sheltered spot outdoors. (Note: provide protection from wildlife and slugs & snails.) When well established, plant out in late spring/summer in full sun, in a sheltered spot away from drying winds. Wrap up well with fleece or sacking for the first 2 winters in cold areas. Cut back hard very spring to produce a robust plant and maintain the young foliage interest.
Note: This seed comes mixed with quite a lot of chaff – sow the whole lot together.
