Set out plants in sun or shade, keeping in mind that sun encourages flower production. Stephanandra is not fussy about soils, but demands good drainage.
Mulch after planting and for at least two springs thereafter. Tsuga also benefits from a spring application of 5-10-10; make certain to “water-in” the fertilizer well. Provide supplemental water during periods of hot, dry weather. Prune only as necessary to create and maintain desired shape. Provide an ample winter mulch to prevent heaving the first year.
