Planting Perennials

Perennials are plants that live three or more years with some species growing much longer.  The foliage of most perennials die back during winter while the roots remain alive to produce new growth and blooms year after year. Care during the first year is critical to success with perennials.  Once established many varieties will require minimal care. Full sun is essential for most flowering perennials. However, some perennials will tolerate partial sun or shade.  Be sure to read your plant …

Peonies perform best in well drained loamy soil with good air circulation and plenty of sunshine and spring moisture.

This allows plenty of time for root development and nutrient storage before winter. …

With a garden fork lift the entire plant clump and shake or rinse excess soil from roots. …
