As the summer season comes to an end, many gardeners in Southeastern Ontario may be wondering if it’s still possible to plant flowers in September and enjoy a bountiful harvest until the first frost. The good news is that there are several varieties of flowers that thrive in the later part of the season, adding beauty and color to your garden well into autumn. In this blog post, we will explore some of the best flowers to plant in September, discuss whether soil amendments are necessary, and highlight an example of a flower that can be planted in the fall to overwinter and bloom early the following year. How much do we love late season Blooms.
Late Season Flower Varieties
While the options for planting flowers in September may be more limited compared to the spring or early summer, there are still several varieties that perform exceptionally well in the cooler temperatures of autumn. Here are some flowers that you can consider planting to extend your blooming season:
a) Chrysanthemums: Known for their vibrant colors and abundant blooms, chrysanthemums are a popular choice for fall gardens. With their long-lasting flowers, they can provide a stunning display until the first frost.
b) Asters: Asters are hardy perennials that produce daisy-like flowers in various shades of purple, pink, and white. They are ideal for adding late-season color to your garden and are often visited by bees and butterflies.
c) Rudbeckia: Also known as Black-eyed Susans, these cheerful flowers feature golden-yellow petals with a dark center. They bloom well into the fall and are excellent for attracting pollinators.
d) Sedum: Sedums are drought-tolerant plants that offer succulent-like foliage and clusters of star-shaped flowers. They come in a range of colors, including pink, red, and white, and can withstand cooler temperatures.
Soil Amendments for Late Season Planting
When planting flowers in September, it’s important to assess the condition of your soil and make any necessary amendments to ensure optimal growth. While some flowers may not require significant adjustments, others may benefit from specific amendments. Here are some general guidelines to consider:
a) Soil Testing: Conduct a soil test to determine its pH level and nutrient content. This will help identify any deficiencies or imbalances that need to be addressed.
b) Organic Matter: Incorporate compost or well-rotted manure into the soil to improve its structure, drainage, and nutrient availability. This will provide a healthy growing environment for your late-season flowers.
c) Mulching: Apply a layer of organic mulch around the base of your plants to conserve moisture, suppress weed growth, and regulate soil temperature. This can be particularly beneficial as temperatures start to drop in the fall.
Overwintering and Early Season Bloom Example
One example of a flower that can be planted in the fall to overwinter and bloom early in the following year is the tulip. By planting tulip bulbs in September, you can allow them to establish their root system during the cooler months. The cold temperatures of winter trigger their dormancy period, and come spring, the bulbs will be ready to burst into color.
Candy, an experienced flower farmer in Southeastern Ontario, shares her success with planting tulips in the fall. She explains that by selecting early-blooming tulip varieties, such as ‘Red Emperor’ or ‘Apricot Beauty,’ she can enjoy beautiful tulips as early as April or May. This not only adds a splash of color to her garden but also allows her to have early blooms for market sales, providing a competitive advantage.
Planting and Care Tips:
To ensure the success of your September planting, consider the following tips:
– Site Selection: Choose a location in your garden that receives full or partial sun, as most flowering plants thrive in these conditions. Ensure the area has well-draining soil to prevent waterlogging.
– Soil Preparation: Prepare the soil by removing any weeds and incorporating organic matter like compost or well-rotted manure. This will improve soil fertility and drainage, providing a healthy environment for your flowers.
– Planting Depth and Spacing: Follow the specific planting instructions for each flower variety, as planting depths and spacing requirements can vary. Providing adequate space between plants allows for proper air circulation and reduces the risk of disease.
– Watering and Mulching: Water your newly planted flowers regularly, especially during dry spells, to establish strong root systems. Applying a layer of organic mulch around the plants helps retain moisture, suppresses weed growth, and insulates the soil.
– Pest and Disease Management: Monitor your plants regularly for signs of pests or diseases. Implement integrated pest management techniques, such as handpicking pests, using organic sprays, or introducing beneficial insects, to maintain a healthy garden ecosystem.
Conclusion
While the gardening season may be winding down in September, there are still plenty of opportunities to plant flowers that will thrive until the first frost in Southeastern Ontario. By choosing late-season varieties like chrysanthemums, asters, rudbeckia, and sedum, you can extend the beauty of your garden well into autumn. Remember to assess your soil and make necessary amendments to provide the best growing conditions for your flowers. Additionally, consider experimenting with overwintering bulbs, such as tulips, to enjoy early blooms in the following year. With careful planning and attention, you can transform your cut flower garden into a thriving business, delighting customers with fresh and vibrant blooms throughout the entire growing season
