REVIVING THE LATE SUMMER GARDEN

“The foliage has been losing its freshness through the month of August, and here and there a yellow leaf shows itself like the first gray hair amidst the locks of a beauty who has seen one season too many.”

–          Oliver Wendell Holmes

Fall Border with Marigolds, Crotons, and Salvias

September in the garden can look a little tired after our hot and humid summer. Many plants become leggy and cease to bloom in the excessive heat. We still have quite a long growing season ahead of us, yet it is too early to begin our fall seasonal plantings.

There is a wealth of fall blooming perennials that can be added to our gardens. Some of my favorites include Salvias, Rudbeckia, Firespike, and Cat Whiskers. Cassia is glorious with its vivid bright yellow blooms.

Mums are a great pick me up at the end of summer. Who can resist their cheery bright colors? Placed at the front door they just say “Hi, I’m happy, welcome home.” Mums typically bloom for about (1) month. When purchasing, look for tight blooms, just beginning to open. They generally will decline if rained on heavily. You can deadhead the blooms to keep the plant looking fresh. Mums are perennial and do wonderful planted in a sunny to part sunny site. They will repeat bloom for you several times if you continue to cut them back after each bloom.

I love the look of ornamental grasses in the garden. This is the time of year when they really shine with their plumes billowing in the wind. Everyone always asks what the pink blooming grasses are they see at this time of year. Muhly or Sweet grass is what dots our dunes and graces the landscape.

Many plants can benefit from being cut back this time of year which will result in new growth and re bloom. It is best to leave some leaf growth, so be careful not to cut back to just empty stems.  Leave at least six inches of the plant. I like to lightly fertilize again now with an organic slow release granular. These practices will result in giving our plants a fresh start.

The table below will help you decide what plants will be best to revive your tired garden.

PERENNIALS: These plants are great at adding punch to our gardens now. They also can be added permanently for re bloom year after year.
