Planting Outdoors

From Mid Autumn TO Mid Spring

Before planting out dig in plenty of well rotted manure or compost into a hole that is 2 or 3 times the width of the pot but not deeper. They should be planted, spreading the roots out, so that the top roots are near the surface. Mulch over the top.

 

Propagation by cuttings

From Mid Spring TO Early Summer

Take soft wood cuttings in spring to early summer. Cleanly cut up to a 10cm long stems, remove lower leaves and pinch the tip out, dip the stem into rooting hormone, fill a container/pot with suitable compost, make holes around the edge of it and plant the cuttings, water in well, cover with a polythene bag and place somewhere warm, lake the bag off twice a week to air the cuttings. Keep the cuttings moist until well rooted. Harden off when well rooted and pot on into individual pots increasing the airing to let the leaves to develop. Remove rotten, dying or dead cuttings regularly.
