Planting young plants

From Early Spring TO Early Spring

Can be purchased from good nurseries in pots and planted straight into the growing site. Establish plants in the garden in spring in a sheltered, sunny place in free draining acid or neutral soil. Grow pot plants in a soil based compost such as John Innes number 3, adding peat or peat substitute to make up to a quarter of the volume.

 

Propagation

From Early Spring TO Mid Summer

Sow seeds under glass during spring or take semi-ripe cuttings in summer.
