symphytum officinale
PERENNIAL
Comfrey leaves are used as a compost activator and a mulch, they also make a useful liquid manure. A variety called Bocking 14 has been developed as a sterile plant that does not produce seeds, as comfrey will seed very easily. Our variety will self seed, so is best used in a well maintained area. Sow March-June. You can chill in the fridge for 14-28 days before sowing to activate the seed for more successful germination. Sow indoors in trays, thinly, 12mm deep. Harden off for 7-10 days after risk of frost. Plant out 60cm apart.
