If you’re gardening in USDA Zone 7, you’re fortunate to enjoy a moderately temperate climate with relatively mild winters and warm summers. September is a transitional month that brings the start of the fall planting season. With the right choices, you can set the stage for a bountiful autumn harvest or a beautiful late blooming garden.

Vegetables To Plant

September marks an ideal time to plant certain cold-tolerant vegetables. With the hazard of frost still a few weeks away, the following crops not only thrive in this season but will also offer a late harvest before winter sets in.

Kale

Kale is a cold-hardy green that thrives in cooler temperatures. Ideal planting times in Zone 7 are early to mid-September. Kale can withstand temperatures as low as 20°F (-6°C), making it highly suitable for fall gardening. It germinates quickly and can be harvested at various stages, after about 30 days for baby greens or 60 days for mature leaves. Additionally, frost can actually enhance kale’s flavor, making it sweeter and more palatable as the cold sets in.

Spinach

Spinach is another great choice for September planting in Zone 7. Sow seeds directly into well-draining soil approximately 1/2 inch deep. Germination occurs within 5 to 10 days, and spinach can tolerate temperatures down to 20°F (-6°C). Ideally, sow seeds early in September for a late fall harvest. Regular watering is essential, especially as the plants mature, to encourage robust leaf growth without bolting.

Radishes

Radishes are incredibly fast-growing and can be sown in late summer for an early fall harvest. In Zone 7, they can be direct-seeded right up until the first frost. Choose varieties like ‘Cherry Belle’ or ‘French Breakfast’ for a quick turnaround; they mature in about 25 to 30 days. Radishes prefer cooler temperatures and can tolerate light frosts, making them perfect for fall gardens.

Carrots

Late summer signifies the perfect time for planting carrots. Sow seeds in early to mid-September, approximately 1/4 inch deep. Carrots benefit from consistent moisture yet require well-drained soil to thrive. They are resilient, with tolerance down to about 20°F (-6°C). Harvest can start roughly 60 to 75 days after sowing, offering a sweet and crunchy addition to your fall meals.

Broccoli

Broccoli is another cold-hardy vegetable that can be sown or transplanted in late summer for an autumn harvest. Plant seedlings in mid-September for best results, as they typically require 100-150 days from seed to harvest. Broccoli thrives in temperatures between 60°F to 70°F (15°C to 21°C) but has tolerance facing light frosts, particularly when grown in a cold frame or garden cover.

Beets

For vibrant roots and lush greens, beets are an excellent choice to plant in September. These veggies can be sown directly into the soil from early to mid-September and typically take about 50 to 70 days to mature. They are tolerant to cold temperatures and can handle frosts well, making them a resilient crop for fall gardens.

Swiss Chard

Swiss chard provides beautiful, edible foliage and is very easy to grow. In Zone 7, plant Swiss chard seeds directly into the ground as early as the last week of August or early September. Swiss chard is exceptionally tolerant of cold, enduring temperatures well into the 20s°F. It provides a continuous harvest all the way into late fall, as the leaves can be cut multiple times, ensuring ongoing production.

Turnips

Sow turnip seeds directly into the soil in mid to late September for a dependable late fall harvest. Turnips grow quickly and reach maturity in about 45 to 60 days. They thrive in cooler weather and can withstand light frost, making them resilient and easy to grow in the fall. Not only are turnips nutritious, but both the roots and leafy greens can be harvested for your meals.

Mustard Greens

Rich in vitamins A, C, and K, mustard greens can be seeded in September, quickly sprouting in cooler weather. Plant directly in the ground about 1/2 inch deep. With a quick maturity time of 30 to 60 days, these greens thrive in temperatures ranging from 55°F to 75°F (13°C to 24°C) but can tolerate light frosts, adding a spicy kick to salads or stir-fries.

Garlic

Though the ideal planting time for garlic is usually in the fall, planting it in September can provide an excellent head start for a rewarding spring harvest. Cloves should be planted approximately 2 inches deep in well-drained soil. Garlic is not frost-sensitive, and when planted in September, it has ample time to establish roots before winter.

Flowers To Plant

September is also an opportune time to plant various perennial and annual flowers that will bloom through the fall or prepare your garden beautifully for the coming spring. Here are some flowers to consider:

Asters

Asters are quintessential fall perennials celebrated for their vibrant colors. These bloom from late summer into fall and are perfect for planting in September, providing a burst of color as many summer flowers fade away.

Chrysanthemums

Chrysanthemums, or “mums,” are icons of autumn with their dazzling array of colors. Plant them in late summer or early September for best blooms in October and November.
