Do phlox bloom all summer long?
Come July, garden phlox (Phlox paniculata) is a staple of the garden. This long-blooming perennial flowers all summer and can continue its display into fall. Newer types like 'David' garden phlox, however, are mildew-resistant, which keeps theMORE.
Phlox are not only Rachel's favorite perennials; they have been favorites in American gardens for well over 100 years. It's not hard to see why. They are long blooming, hardy and long-lived, easy of culture, often fragrant and never need staking.
- Garden phlox (Phlox paniculata), also called perennial phlox, grows well in USDA zones 4 through 8. At 2 to 4 feet tall, garden phlox blooms later in the summer with bursts of lavender, white, coral, red and violet, depending on the cultivar.
- Plant zinnias in mixed plantings with other summer-blooming annuals, or place small groups of zinnias among perennials. They are at home in cottage and children's gardens, and they are often grown in cutting gardens. Shorter zinnia varieties are ideal for containers.
- Snapdragons (Antirrhinum majus) are short-lived tender perennials, which are often grown as annuals. If they survive through the winter, they will bloom every year, but they rarely survive year to year.
Remember to remove the dead/faded flowers so that your plants can rebloom. If you have tall phlox, cut the stems back to about 1 to 2 inches above the soil after the first killing frost. (See local frost dates.) Divide tall garden phlox every 2 to 3 years to ensure healthy and disease-free plants.
- Perhaps the most confusing group of plants, when it comes to pruning times, is flowering trees and shrubs. A general rule of thumb is to prune summer and fall flowering trees and shrubs in the dormant season (late winter / early spring) and to prune spring flowering trees and shrubs soon after their flowers fade.
- To reduce the risk of removing these buds, prune just as the flowers begin to fade. Often, the earlier you get it done after bloom, the quicker the shrub can recover, producing more and larger blooms next season. Don't prune these hydrangeas to the ground in late fall. Doing so removes all of next year's flower buds.
- Prune these hydrangeas only after bloom in the summer and not in the fall. Old wood hydrangeas start developing their bloom buds for next year in August and September. If you don't prune your hydrangeas real soon, then it is better to wait until next year. Otherwise you won't have any blooms next spring.
