Horticulture Sources and Advice

  • You can often obtain seeds or plants from our mail order company of choice Thompson & Morgan
  • They recommend seed sowing as follows ‘Sow February to April. Germinate at 20-30C on the surface of a good free draining, damp seed compost. Apply a layer of compost or vermiculite, ¼in deep. Place in a propagator or seal container inside a polythene bag until after germination which usually takes 7-21 days. Do not exclude light at any stage, as this helps germination.
  • Transplant seedlings when large enough to handle into trays or 3in pots. Grow on in cooler, well lit conditions for 10-15 days before planting out after all risk of frost, 12in apart.’
