Planting a Perennial Garden
Plant perennials for blooms that come back year after year with little maintenance.
Select Your Perennial Garden Plants
Choose flowers with a reputation for being sturdy and dependable. Coneflowers, astilbes, coreopsis, creeping phlox, veronica, and black-eyed Susans are beautiful perennial flowers you can count on. Select a mix of tall and short plants. Plant tall ones in the back and short ones in front and along the sides of your garden bed.
Decide Where to Plant
Most people put their perennial gardens against a backdrop like fences and garden walls. Try to pick a spot that provides at least 6 hours a day of sunlight for your sun-loving plants. If your area is shadier, plant shade-lovers, such as hostas and bleeding hearts.
Perennials are tough plants. They're less fussy about when you plant them or move them. Most perennials can be planted any time from the last winter frost through autumn. When planting or transplanting, dig a hole that's twice as wide and no deeper than the container, then backfill the hole with soil. Make watering easier by grouping plants with similar water requirements together.
Perennial bulbs should be planted based on when they bloom. If you’re looking ahead to springtime varieties, then be sure to put them in the ground in early fall. For perennial bulbs that bloom in summer, aim to plant them in early spring, once all chances of frost have passed. Always refer to the plant tag to get the proper planting depth and spacing.

Care for Your Perennials
Deadhead your flowers by removing spent or misshapen blooms. This will encourage more flowers to grow. After your plants have matured, apply a pre-emergent weed preventer, such as Miracle-Gro® Garden Weed Preventer®, throughout your garden bed to help prevent weeds. Make sure to only apply the weed preventer near plants listed on the product label. Then, spread 3 inches of mulch around the plants, which will also help prevent weeds by blocking access to sunlight and keep soil moist. When your mature perennials are not in bloom, you can divide them and create starter plants to plant elsewhere.
