Sow Witkiem Manita seeds from February to April, with seedlings emerging in 7-14 days. For February sowings, use pots or root trainers in the greenhouse or under cloches. Later sowings can be directly drawn into the growing site, placing seeds 5cm (2in) deep in rows. Space the seeds 10-15cm (4-6in) apart, and have rows 60cm (24″) apart. If sowing indoors, transplant seedlings to the growing site in March, spacing them 10cm (4″) apart in rows 60cm (24″) apart.

Outdoor sowings should be thinned to 10cm (4″) apart, and the thinning can be transplanted to create extra rows. Once beans begin to form, remove the top 6cm (2 1/2in) to discourage blackfly. Harvest the succulent, tasty young beans from June to August. As a handy tip, this variety can also be sown in late October or November under cloches for an early spring crop.
