Planting young plants

From Early Spring TO Early Spring

Plant pot grown plants in early spring, in moderately fertile, moist but well-drained, alkaline to neutral soil in full sun. These are tall plants with prone to wind damage so may need support from canes or planting against a trellis or south facing wall.

 

Planting Tubers

From Early Spring TO Early Spring

Plant tubers 10-15 cms deep, 30-45 cms apart. If they are already sprouting, make sure the shoots are pointing upwards. You can cut them into pieces (don't let these dry out), ensuring that each piece has a bud on it, and plant them seperately.
