Prepare your garden bed in the early spring after the last frost in order to provide nutrients to existing perennials and plant annuals. Because the climate of Maryland dips to extreme cold conditions, most annuals are not able to survive the freezing soil.

Decide where to plant landscaping shrubs. Shrubs are a popular choice to reduce street sound and create privacy. Both spicebush and red chokeberry begin to flower after the last frost. Summer shrubs like sweet pepperbush not only bestow your yard with spiky white flowers, but they also attract hummingbirds. Late-summer flowering shrubs include swamp azalea and American elderberry. In addition, camellia, wintersweet and flowering quince contribute vivid flowers to your wintry landscape.

Spread 6-inches of mulch around shrubs and flowering plants to keep their roots warm in the winter temperatures. Also, keep them watered up until the late fall. Moist soil is warmer than dry soil.

Choose ornamental plants to plant either in containers or in your gardening beds. Spring wildflowers such as spring beauty, dutchman’s breeches and smooth sweet cicely can be planted after the last frost and bloom in early spring. Summer plants, such as swamp milkweed, yellow violet and boneset, should be planted in the early spring,. Spruce up your fall and winter with ornamental plants such as winter heathers, Iceland poppies and snapdragons; these should be planted in the fall for late fall and wintry blooms.

Broadcast seeds into your gardening bed according to the spacing instructions on the seed package for early spring and summer flowers. Dig holes twice the size of the container-grown plant's root balls and at the same depth as the plant was planted in the container.
