why my two bushes doesn't have any flowers this summer? how can I help them? Thank you.
Sufficient direct sunlight is essential for variegated weigela to produce bountiful blossoms. To maximize its late-spring profusion of pink, trumpet-shaped flowers, the planting site should provide full sun.
For best flowering, prune variegated weigela right after it finishes blooming each year.
Nutritional deficiencies can trouble weigelas. With nutrients lacking, flowers develop late, are undersized or fail to develop at all. Most soils don't lack the nutrients plants need. Instead, deficiencies result from conditions that limit the plant's access to nutrients that are there. Overly wet soil can be one cause. Variegated weigela thrives in moist but well-drained soil.
Late spring frosts can also nip early flower buds and prevent blooms. If your weigela sustains cold damage, remove all dead and damaged wood. This redirects the shrub's energy into healthy new growth that translates to more blooms this year and next.
