September gardening tips from the Acton Garden Club

Editor’s note: Judy Dembsey, master gardener and member of the Acton Garden Club, has put together some gardening tips for August to help your garden be a success.

Fertilize established lawns early in the month to support renewed cool-season growth. Grass plants are actively producing roots at this time and take up more mineral nutrients than at any other time of year.

Check for yellow jackets and bald-faced hornet nests before pruning or shearing. Strike the hedge with a long-handled rake and carefully watch for flying wasps. Ground wasps can also be a problem. Spray in the evening when wasps return to their hole.

Many evergreens lose their older needles. This is normal and is most noticeable on white pine and arborvitae. These are the inner needles. Look at other trees to see if this is also occurring.

Plant, divide or move early blooming perennials. The general rule is to divide spring blooming perennials in the fall and fall bloomers in the spring. Divide Hosta (funkia), Hemerocallis (daylily), Dicentra (bleeding heart), Heuchera (coralbell), Pulmonaria (lungwort) and Paeonia (peony) now. Late summer flowering shrubs may be pruned after blooming is complete. Transplant evergreens until the end of the month. Water these plants regularly until Thanksgiving so they have an opportunity to establish themselves.

Shop now for spring bulbs to get the best selection. They may be planted this month. Discard soft bulbs. Daffodils are deer and rodent resistant. Dig up summer bulbs, tubers or rhizomes of plants such as: gladioli, tuberous begonias, dahlias, caladiums and cannas. Allow them to dry, cut off the leaves and store in mesh bags in a dry, cool, airy space. Most unfinished basements will work well.

Cut down and dispose of plants that are infected with powdery mildew. The fungus which causes powdery mildew overwinters on infected leaves. Disposing of those plants now can help lessen recurrence of the disease next year.

Goldenrod is not responsible for the sniffling, sneezing, runny nose and watery eyes associated with hay fever and allergies. It is falsely accused because it flowers at the same time as many other annual weeds.

September is a good time to plant new woody ornamentals in the landscape. Plant roots will continue to grow as long as the soil temperatures are above 40 degrees. The cooler and moister conditions of fall as well as the shorter days will reduce moisture stress and improve planting success.

Plant some fall color. Mums and asters will provide some traditional fall color. For a long season of color, plant some flowering cabbage or kale. Flowering cabbage and kale can tolerate temperatures into the teens.


With such variety, it is easy to see why these autumn-blooming perennials take center stage in so many gardens. Here are a few varieties to explore:

Sapphire Mist — Buy from Proven Winners
Symphyotrichum dumosus

Blue and yellow daisy-like flowers bloom from August to October. Sapphire Mist is drought tolerant and attracts butterflies. Grows 12 to 16 inhes tall and up to 24 inches wide.

Add some pink to your late summer and fall garden with Pink Mist. Grows 12 to 16 inches tall and up to 24 inches wide. A great choice for containers or in the landscape.

Aster ×frikartii

One of the first hybrids by Swiss breeder Carl Ludwig Frikart (1918), this was named for one of three mountain peaks visible from his nursery. Lavender-blue flowers from late June through early October. The Pictons recommend pairing with Symphyotrichum novi-belgii ‘Saint Egwyn’.

‘October Skies’
Symphyotrichum oblongifolium

Aromatic asters are heat- and cold-hardy—and derive their name from the light scent they produce when crushed. These make good companions for small shrubs and trees particularly chrysanthemum. ‘October Skies’ has purple-blue flowers .75 inches across and reaches 18 inches high.

‘Patricia Ballard’
Symphyotrichum novi-belgii

The reliably blooming bright purple-pink double flowers, 1.75 inches across, on branched sprays that grow up to 36 inches tall make ‘Patricia Ballard’ a good choice for the front or mid-border. Bred at Old Court Nurseries by Percy Picton in 1957.

‘Purple Dome’
Symphyotrichum novae-angliae

One of the shorter New England asters, ‘Purple Dome’ produces branching sprays up to 24 inches tall. “This is a beautiful selection—naturally compact, floriferous, deep purple,” Jim Sutton says. “A dense grower with excellent mildew resistance.”

Aster 'Little Carlow'

Compact clumps will reach 20 inches across in 2 years, producing sprays up to 4 feet tall. Free-blooming flowers are about 1 inch across. These are popular in formal borders and meadows. “Contrast the dense sprays of this aster with textures from other plants,” suggest Helen and Paul Picton, co-authors of The Plant Lover’s Guide to Asters.

Symphyotrichum novi-belgii

Magenta flowers with yellow discs grow from late summer into autumn. Try it in gravel beds, borders, and informal gardens.

Symphyotrichum laeve

Also known as smooth blue aster, ‘Calliope’ is unique for its height and purple-tinted stems, making it a good choice for cutting. It grows to more than 6.5 feet high in good conditions. As such, say the Pictons, “it lends itself to more wild or naturalistic planting schemes.”

‘Helen Picton’
Symphyotrichum novae-angliae

This New England aster sports vibrant purple flowers, 1.5 inches wide, in large sprays atop upright stems to 48 inches tall. According to its namesake, “Swaths of perennial grasses . . . can be given an easy boost of color in mid-autumn with large clumps of this aster.”

Symphyotrichum ericoides

This bushy heath aster bears masses of small, soft pink flowers from late summer through mid-autumn. Tall stems and deep green foliage make ‘Lovely’ excellent for cutting. More drought tolerant than many asters, it also does well in full sun in a border or container.

Symphyotrichum novae-angliae

The pale coloring—white flowers 1.75 inches across with pale green foliage—makes this unique among New England asters. Woody clumps produce sprays of compact branches up to 4 feet tall, so it’s best suited toward the back of a border.

‘Mrs. S.T. Wright’
Symphyotrichum novae-angliae

Profusions of lilac flowers, 2 inches across, bloom on sprays that grow up to 5 feet tall. This classic cultivar introduced by H.J. Jones in the UK more than 100 years ago is still popular among gardeners and butterflies alike.

‘Veilchenkönigin’ (‘Violet Queen’)
Aster amellus

Each branchy clump of this compact plant grows to about 16 inches high and 12 inches across. The small violet flowers (2 inches across) seem to glow with depth of color. The Pictons recommend placing these blooms next to structural grasses.

Symphyotrichum lateriflorum

A bushy plant with petite, skyward-facing white flowers a half inch across, this mid-fall bloomer differs from other varieties in the deep coloring of its spring growth. The yellow discs of the flowers fade to purple. Spreads to about 12 inches across.

‘Snow Flurry’
Symphyotrichum ericoides f. prostratum

Heath asters tend to have a bushy habit, hairy stems, smaller leaves, and sparser ray florets than other asters. This aster sits just 4 to 6 inches above the ground and spreads to about 1 foot. White flowers about a half inch across create what looks like a blanket of mid-autumn snow. The Pictons recommend planting ‘Snow Flurry’ where it can cascade.
