Summer flowers add color to the landscape during the height of the warm season. Whether you grow annuals, perennials or a combination of the two, proper care is necessary to keep the flowers looking their best. Some flowers only bloom for a short period of time, while other produce vibrant blooms from spring until fall. While specific care depends on the type of flowers, there are general care requirements that benefit nearly every plant in your summer flower garden.
Water flowering plants deeply once a week, and twice a week during extended hot, dry spells. Irrigate at the base of the plants, moistening the soil in the bed to a 6-inch depth.
Spread a 2-inch layer of mulch, such as bark chips, over the soil if the bed isn't already mulched. Mulching preserves soil moisture, prevents weeds and keeps the flower's roots cool.
Remove the wilted flowers from the plants once weekly throughout the summer period. Break off the old flower heads ¼ inch down the stem behind the flower. Flower removal prevents seed formation and encourages the flowers to bloom more.
Trim back flowering plants, particularly perennials, that have become overgrown and leggy. Cut the plant back to one-half its previous height with a pair of shears. Severe trimming often encourages fuller growth and sometimes leads to more flowering.
Weed beds once a week, especially in the middle of summer when weeds often grow the quickest. Pull weeds up by the roots as soon as they become visible. While mulch prevents most weed problems, it does not eliminate them.
