Generally, the flaxes genus thrives in well-draining, sandy soil and a sunny location. Begin the planting process by preparing the area with compost or organic matter. Plant seeds or young plants at appropriate spacing, typically 6 inches apart. Water immediately after planting and regularly thereafter until established. For this genus, a slightly drier environment is preferred over water-logged conditions. Though these are general guidelines for flaxes, it's crucial to investigate the needs of individual species, as there can be variances.
