No herbicides are labeled for apios, so mulch or hoeing may be necessary. Usually whole tubers are planted. The seedlings are very heterozygous, and many will not have desirable horticultural traits. Selections of the best plants may be maintained clonally by planting the tubers. Rhizobium for southern peas is satisfactory for use in apios.
Much research remains to be done on apios culture and utilization.
