Tina talks about how much taller asters grow when they are in your garden as opposed to the ones in the garden center.
Native Asters put on quite a show this time of year. Seen along roadsides across the northeastern part of the country asters provide a bold pop of color When other plants and perennials begin to fade into the landscape. They are a staple in many perennial gardens and borders, with clusters of star daisy like flowers. Colors range from white, pink to hues of lavender purple and are at the forefront of fall gardens right along side mums, cabbage and winter pansies.
Aster novae-angliae also known as New England aster and novae-belgii, New York asters are North American natives hardy to zones 4-8 and commonly found in your local garden center typically beginning in late August through the fall. They are a key food source for pollinators and wildlife alike. Late blooming flowers, like asters provide a viable food source necessary to supply much needed energy for pollinators like the monarch butterfly and hummingbirds as they migrate southward. They are also a pollen source for bees as well, especially honey bees.
In their natural habitat they look different than what you see in local garden centers. When grown commercially they are typically pruned twice during the summer months to encourage branching to maintain a certain height ranging from six to twelve inches to fourteen inches at the most. Wild asters can grow up to six feet in height without pruning. They flower effortlessly with a minimum of six hours of direct sunlight and are right at home in container gardens as they are growing in garden beds. Caring for asters are simple and similar to garden mums. The key is to plant asters in early fall to establish a healthy root system. They prefer full sun to partial shade. If grown in shady area of the garden plants tend to be leggy and will need to be staked. Asters are also drought tolerant and do best in well drained soil and can be susceptible to root rot if planted in heavy wet soil. First year plants don’t need to be fertilized heavily, once they are established begin fertilizing in early spring. Add organic compost around the base of the plants and use a balanced fertilizer monthly. Overall plants are relatively maintenance free and are seldom bothered by pests. Powdery mildew can occur but is no real threat to the plant. Spraying an organic fungicide early in the season can help prevent it.
Fall is a season of new beginnings, the days are shorter and the temperatures cooler. The landscape becomes bursting with rich colors of burgundy red, gold, purple and yellow. Hardy mums are front and center of the fall garden along with pumpkins and gourds. Whether you grow them as seasonal annuals or perennials that come back in the garden every year mums give your landscape a pop of color from September to November. If you find them to be a bit fussy and a challenge look no further we have the answers.
Mums are an easy to grow low-maintenance plant that grows equally well in garden beds and mixed containers. They are drought resistant and relatively pest free. Planting mums in the garden is a great way to add late season color to your landscape. They continually bloom for weeks at a time and prefer at least 6 hours of direct sunlight per day. Preparing the soil for mums requires adding quality compost to the existing garden beds. Improving the condition of heavy dense soil improves growing conditions for the plants. Mums prefer well-drained soil.
Watering mums can be a challenge. The most common problem is overwatering. As mentioned above garden Mums are drought tolerant. Overwatering can lead to leaves wilting, which can be mistaken for being too dry. This is common problem for those who have outdoor irrigation in place. If this has happened to you take a hands off approach, meaning ‘back off’ of regularly or daily watering. As the daylight decreases and nights turn cooler plants are not drying out as quickly as they do in a garden during the summer months. If you are growing Mums in containers allow the soil to dry thoroughly. Physically checking the soil daily with your hand is helpful. If the pot or container feels light in weight and the soil feels dry then proceed with watering. Avoid the mums drying and wilting. Letting them go too dry too long will diminish the blooms and color.
Fertilize mums in mixed container gardens using Jack’s Classic blossom booster 10-30-20 or All -Purpose 20-20-20. Plants in the garden should be planted using Espoma Bio-Tone Starter Fertilizer the first year. Then fertilize monthly the second year of growth from May to August.
Hardy mums can tolerate the frosty cool nights in the fall and can easily be overwintered for the next season. The key to successfully overwintering mums is to plant early. Planting in early fall allows the plants to become established before winter. Once a hard frost occurs stems and leaves will turn black. Cut plant back leaving an inch to one and a half inches above the ground and cover with mulch. Garden Mums can grow naturally to heights of 12-48 inches. To keep plants compact and encourage more branching pinch back plant tips twice during the summer months. First pinching occurs in June. When plant has grown 6-8 inches pinch tops off each branch about 2 inches. Pinch again in July, 2 inches off each branch from the new growth. This will strengthen plants and encourage blooming.
Falls rich display of colorful garden mums are unmistakable and a welcome sight after a long hot summer.
