Soil preparation is essential for successful establishment of herbaceous
plants and display of color. When planting a large bed, it is easier to amend the entire area. Add 2-3" of either
peat moss, compost, black topsoil or rotted manure and till to a depth of 4-6". Deeper soil preparation is necessary
if you are planting large containers of perennials or ornamental grasses. In these cases, follow the directions for
planting containerized trees and shrubs. Click here to jump to that article.
After the soil is adequately prepared, set the plant at the same
level it had been in the container. Firm the soil around the plant to eliminate air pockets and water thoroughly.
Using a water soluble fertilizer at watering can be beneficial.
Avoid a high nitrogen fertilizer since this can promote more foliage than flowers. Look for fertilizers that are high
in phosphorus and potassium. These nutrients help plant establishment and flowering.
