Plant of the Month: Asters

As September arrives, the growing season is beginning to wind down, with many gardens transitioning from the bright blooms of summer into the colors of fall. This makes it the perfect time to spotlight this month’s featured plant in The Gardening Gazette. Each month, we highlight a plant by sharing its botanical and common names, key characteristics, and helpful growing tips to support your gardening success.

For September, we are featuring New England Aster (Symphyotrichum novae-angliae), commonly known as New England Aster. This hardy perennial is a great choice for Indiana gardens because it provides vibrant late-season color and is an important source of food for pollinators. New England Aster produces daisy-like flowers with purple, pink, or violet petals surrounding yellow centers and typically blooms from late summer into fall.

New England Aster performs best in full sun and prefers moist, rich, well-drained soil. It can tolerate a variety of soil conditions, including clay soils, making it adaptable to many Indiana landscapes. This tall, upright perennial can reach approximately 3 to 6 feet in height and works well in perennial borders, native plant gardens, naturalized areas, rain gardens, and pollinator-friendly landscapes.

One of the greatest benefits of New England Aster is its value to pollinators. Its late-season flowers provide an important source of nectar for bees, butterflies, and other beneficial insects when many other garden plants are beginning to fade. The seeds can also provide food for birds, making New England Aster a valuable addition to gardens designed to support wildlife.

New England Aster is relatively easy to grow and maintain, but its tall growth habit may cause the stems to bend or fall over, especially when grown in rich soil. Pinching the stems earlier in the growing season can help create a shorter, bushier plant and reduce the need for staking. Providing good air circulation can also help reduce the risk of foliar diseases such as powdery mildew.

Did You Know?

New England Aster was once classified in the genus Aster, but many North American asters were reclassified into the genus Symphyotrichum. Although its scientific name has changed, gardeners continue to commonly refer to these plants as asters.

• Missouri Botanical Garden – New England Aster Plant Finder – https://plantfinder.mobot.org/PlantFinderDetails.aspx?taxonid=292654&isprofile=1&basic=new%20england%20aster

We’re excited to continue our Plant of the Month feature and highlight plants that bring beauty, seasonal interest, and benefits to Indiana gardens.

September Garden Task

HOME (Indoor plants and activities)

Houseplants love being outdoors for the summer but the time to bring them indoors is fast approaching. September (like March) is a transition moth for the seasons and for our weather. Look for widely varying temperatures, moisture and wind. Prepare houseplants to come back in the house as overnight temps begin falling into the high 50’s. It will be necessary for houseplants to be cleaned up a little, pruned back and given a systemic pesticide so you are not bringing in any insects with your plants. Most garden centers carry a systemic made for houseplants. If you are bringing in annual geraniums for the winter, they should be cut back by at least half, so they don’t get leggy over the winter. If you have houseplants indoors, consider purchasing small houseplant lights to accommodate small clusters of plants around the house. Make sure your houseplants are pet friendly. If you have new plants coming in the house for the first time, check online and make sure you have nothing that will harm your pets. ASPCA list: https://www.aspca.org/pet-care/aspca-poison-control/toxic-and-non-toxic-plants

YARD (Lawns, woody ornamentals and fruits)

This summer was hard for the ornamentals in the garden. Even if you were not directly affected by the recent storms, get outside and look at all of your trees and shrubs carefully. I recommend taking photos to keep a record of your landscape in case you have a problem in the future. This will help you notice if there has been a change if you happen to be a more indoor type person.

Now is the time to think about fertilizing your lawn and laying down weed killer. September is the best time to work on your cool season grass lawn (Kentucky Blue) Here is information from Purdue Turfgrass Dept. Early to mid-September is the most important time to fertilize cool-season turfgrasses like creeping bentgrass, Kentucky bluegrass, perennial ryegrass, and tall or fine fescue. September fertilization is crucial on all turf areas regardless if it is a lawn, athletic field, or golf course green, tee or fairway. Fertilization in mid-September encourages the production of new tillers and/or rhizomes and stolons that will increase the density of a turf. Fertilization in September also encourages rooting and production of storage products that will help the plant survive the stresses of winter and next year’s growing season. Once the temperatures start to cool in the first week or two of September, most turf areas should be fertilized with 1 lb. N/1000 sq ft using a fertilizer with 25-50% of the nitrogen as slow release (sulfur or polymer-coated urea, urea formaldehyde, or natural organics). More fertilizer information is available in https://www.extension.purdue.edu/extmedia/AY/AY-22-W.pdf.

GARDEN (Flowers, vegetables and small fruits)

Keep the garden well-watered during dry weather and free of weeds, insects and disease. Weeding in early September before weeds form seeds is a good way to prevent weeds for next year. If you are interested in planting mums in the garden, do it as early as possible. One way to know that a mum is hardy and will regrow in spring is to look for tiny leaves around the bottom of the flower stems. Those basal leaves are the leaves for next spring. Plant early in September so mums can get well rooted in the garden and regrow in spring.

Plan on not cleaning up the garden so meticulously in fall. Plan on leaving stems up of native plants especially coneflowers and other natives for the next year. Stems that are left standing for a second summer and that are dry are the stems that native bees Need to nest in. Here is more information of the practice and what native bees need. https://beelab.umn.edu/create-nesting-habitat

Crop of the Month: Tillage Radish

As August arrives, the growing season is still thriving, but many gardeners are beginning to think ahead to fall and prepare their soil for future crops. This makes it the perfect time to highlight this month’s featured cover crop in Urban Ag Chronicles. Each month, we highlight a cover crop by sharing its scientific and common names, crop type, key benefits, and helpful growing information to support healthy soils and productive growing spaces.

For August, we are featuring Tillage Radish (Raphanus sativus), also known as Daikon Radish. This fast-growing brassica cover crop is valued for its ability to improve soil structure, capture nutrients, and prepare garden spaces for future growing seasons.

Tillage Radish develops a large taproot that can help break through compacted soil layers, creating pathways that improve soil aeration, water infiltration, and root growth for future crops. As the radish roots decompose, they add organic matter back into the soil and help support soil organisms that contribute to a healthy growing environment.

In addition to improving soil structure, Tillage Radish helps capture and hold nutrients that might otherwise be lost from the soil. The deep root system acts like a “nutrient sponge,” absorbing available nutrients and releasing them back into the soil as the plant residue breaks down. This makes it a valuable cover crop option for improving soil fertility and supporting future plant growth.

Tillage Radish is typically planted in late summer or early fall and performs best in full sun and well-drained soil. For Indiana growers, late summer planting allows the radish to establish before colder temperatures slow growth. When incorporated into a cover crop plan, Tillage Radish can help reduce erosion, suppress weeds, and improve overall soil health.

Did You Know?
Tillage Radish is sometimes called a “bio-drill” because its large taproot naturally creates channels in the soil, allowing air, water, and future plant roots to move more easily through compacted areas.

Local Resources

The Times of Northwest Indiana is collecting information on local food resources throughout the Region to build a public directory of food pantries, meal programs, and assistance services.
