Set plants about 10 feet apart to allow for ultimate spread. (Dwarf varieties may be planted closer together.) Weigelas are widely tolerant of growing conditions, but will prosper if given full sun and a well-drained but moisture retentive soils.
We recommend an organic year-round mulch to preserve moisture. Prune heavily after flowering to control unruly growth by removing approximately 1/3 of the old growth to ground level. Thinning of younger wood to open up the bush is also beneficial from time to time.
