All About Perennials

Perennials grow year after year without replanting. The heart of a flowering garden may be the unchanging perennials, brightened with a yearly change of annuals interspersed for contrast. Some perennial varieties multiply and grow larger as the years pass.

Selecting Plants

Ensure that all plants that you select for a particular garden area require the same light conditions. Flowering periods of perennials vary; choose plants with a variety of heights and plant your beds with the tallest plants at the back and shorter plants at the front to ensure the best display. Use a variety of colour, leaf shape, and flower shape for added interest.


If you buy perennials but cannot plant them the same day, water the packs thoroughly and put them in the shade to prevent excessive wilting. Prepare flower beds by spading deeply. Build up soil with the addition of peat moss, composted manure or top soil.

How to Plant

Evenings or cloudy days are the best times to plant. Refer to the information tag that accompanies the flowers to determine the spacing requirements for your plants. Soak the plants before removing them from their containers. Keep as much soil around the roots as possible and plant the root ball below the soil line. Remove all buds and blooms after planting to help the plants establish themselves. We recommend the use of Miracle Gro Fertilizer when you do your transplanting.


Water plants thoroughly when first planted. Thereafter, water whenever the soil is dry. Water early in the day with a soaking technique at ground level. Don’t rely on rainfall to keep plants adequately watered.

After Planting Care

Perennial beds should be kept free from weeds, especially before plants are established. Flowers should be removed when overbloomed to prevent seed formation and promote future blooming. Never remove leaves until they have completely matured and died. Some perennials become overgrown after three or more years; select the younger, outside growth to replant and discard the old material. Fertilize every two weeks. We recommend the use of Miracle Gro Fertilizer.

Winter Preparation

In late autumn, flower heads and remaining foliage should be trimmed to within a few inches of the ground. Soil between plants should be spaded and compost added to fertilize and aerate the soil.
