Celery - Lathom Self Blanching
This heavy yielding variety produces long stringless sticks of crisp, tasty celery without the need for earthing up in trenches. Celery 'Lathom Self Blanching' is reasonably free from bolting so it can be sown earlier than other varieties and is also useful for growing in plastic tunnels as well as outdoors.
Sow seeds from late winter to spring on the surface of a moist peat based compost, do not cover the seed as light aids germination. Seal in a polythene bag or cover with glass until germination which takes 10-16 days at 21C. Grow on at a cooler temperature 16-18C and in good light but shade from strong sun. Transplant when large enough to handle into boxes. Gradually acclimatise to outdoor conditions before planting out after all risk of frost in late spring. Plant 23cm apart each way in blocks not rows in rich well drained soil. Water copiously in dry spells. Pick the sticks from late July onwards and harvest them all before the frosts. This seed should not be used for culinary purposes.
