Sow seeds at any time of year in trays or pots about quarter of an inch deep in good seed compost. Place in a propagator or warm place. Seal the container inside a polythene bag to ensure a humid atmosphere and leave for 6 weeks. Place outdoors for eight weeks to chill. Transplant seedlings when large enough to handle into 3″ pots. Grow on in a cold frame and plant out the following spring or autumn in a sheltered part of the garden. It may be up to three years before you can plant into it’s final position. Choose a slightly shady, sheltered spot in moist, free draining, lime-free soil. Sounds easy doesn’t it. I understand you can also use prunings to grow from a cutting. Ah well, the seeds cost nothing so I shall give it a go.
Update Sunday 30th October – the seeds are in a tray of damp compost which is inside a polythene bag. They have to stay like that until the middle of December. Tray put outside middle of December. Update 17th January. Tiny green shoots showing.
