As the sweltering heat of summer begins to wane and the cool autumn breeze sweeps across the plains of Oklahoma, avid gardeners begin to shift their focus towards fall gardening. This often-overlooked season offers countless opportunities for bountiful harvests, vibrant colors, and beautiful landscapes. If you’re wondering what to plant in a fall garden in Oklahoma, you’re in for a delightful surprise. Not only can you extend your growing season, but you can also enjoy a variety of crops and ornamental plants that thrive during this time of year.
Understanding Oklahoma’s Fall Climate
Oklahoma’s climate is characterized by hot summers and mild to cool autumns. When planning your fall garden, understanding your USDA hardiness zone is crucial. Most of Oklahoma falls within zones 6a to 7b, which means that the first frost generally arrives between mid-October and mid-November. This mild climate allows for a diverse array of plants, even in the fall.
Fall gardening in Oklahoma also provides a chance to take advantage of the region’s varied soil types. Oklahomans may deal with clay, sandy, or loamy soils, and knowing how to amend these can significantly impact your garden’s productivity.
Essential Crops to Plant in Your Fall Garden
Fall gardening primarily focuses on crops that can handle cooler temperatures and shorter days as winter approaches. Here are some of the best options for a fall garden in Oklahoma:
Cool-Weather Vegetables
These crops thrive in cooler temperatures, allowing you to enjoy fresh, home-grown produce even as the leaves start to change color.
1. Leafy Greens
Leafy greens are among the easiest and most rewarding crops to grow in the fall. Varieties to consider include:
- Spinach
- Kale
- Swiss Chard
- Mustard Greens
These greens are packed with vitamins and minerals, and they can withstand frost, making them perfect for late-season harvests.
2. Root Vegetables
Root vegetables are hardy, nutritious, and ideal for fall planting. They also store well, allowing you to enjoy them long after the harvest. Some of the best options include:
- Carrots
- Beets
- Turnips

These crops can often be sown directly into the ground as late as early September in Oklahoma.
3. Brassicas
Consider incorporating members of the brassica family, such as:
- Broccoli
- Cauliflower
- Cabbage
These plants thrive in cooler temperatures and can be started as transplants or sown directly into the soil.
Herbs for Fall Planting
Herbs are wonderful companions in any garden and can be grown in fall for a fresh, flavorful addition to your cooking. Consider planting:
- Cilantro
- Parsley
- Chives
- Thyme
These herbs can often survive mild frosts and continue to thrive until the temperatures drop significantly.
Ornamental Plants to Brighten Your Garden
Creating a vibrant and visually appealing garden doesn’t have to stop with vegetables. Fall is an excellent time to introduce ornamental plants, adding beauty and interest to your landscape.
Pansies and Violas
These cheerful flowers can provide stunning color to your fall garden. They flourish in cooler temperatures and go dormant during extreme cold but return in spring, providing a great return on investment.
Chrysanthemums
Chrysanthemums, or “mums,” are iconic fall flowers that can provide a striking burst of color in shades of yellow, orange, red, and purple. They thrive in well-drained soil and can beautifully complement the colors of autumn.
Ornamental Grasses
Planting ornamental grasses, such as Miscanthus or Panicum, can add height and texture to your garden. They offer beautiful plumes that sway gracefully in the fall breeze and can provide winter interest after the growing season ends.
Timing Your Plantings
Timing is critical in fall gardening. For most crops, you’ll want to plan your planting to ensure that they have enough time to mature before the first frost. As a general rule:
- Leafy greens and root vegetables can be planted from mid-August to late September.
- Brassicas are best sown as seedlings or transplants towards the end of summer and into early fall.
- Ornamental plants can typically be planted in September and October, giving them time to establish before winter.
Always keep an eye on the local weather, as Oklahoma can experience variable weather patterns that may impact planting schedules.
Soil Preparation and Care
To maximize the success of your fall garden, proper soil preparation is vital. Here are some steps to follow:
1. Soil Testing
Before planting, conducting a soil test can provide valuable insights into the nutrient content and pH level. The Oklahoma Cooperative Extension Service offers testing services that can guide you in making necessary amendments.
2. Amend the Soil
Incorporate organic matter like compost or well-rotted manure to improve soil fertility and structure. For nitrogen-rich crops, consider adding blood meal or fish emulsion as a nutrient boost.
3. Mulching
Applying a layer of mulch around your plants helps retain moisture and regulate soil temperatures. This is particularly important as the air cools down but the soil may still remain warm.
4. Watering Wisely
Maintaining consistent moisture is crucial, especially as you plant new seeds. However, avoid overwatering, as cool weather can lead to root rot in poorly drained soils. A good rule of thumb is to aim for about one inch of water per week, depending on rainfall.
Managing Pests and Diseases
Fall gardens can be susceptible to various pests and diseases. Here are some tips to ensure that your garden stays healthy and productive.
1. Monitor for Pests
Common pests like aphids, cabbage worms, and cutworms can quickly decimate your fall crops. Inspect your plants regularly and consider natural pest controls, such as neem oil or insecticidal soap, for prevention.
2. Crop Rotation
Practicing crop rotation helps keep pests at bay and reduces disease pressure. Try not to plant the same family of crops in the same spot year after year.
3. Disease Resistant Varieties
Whenever possible, choose disease-resistant varieties of plants are crucial when it comes to cultivating a healthy garden. Look for these on seed packets or plant labels.

What are the best vegetables to plant in the fall in Oklahoma?
The best vegetables to plant in the fall in Oklahoma include hardy crops such as broccoli, kale, carrots, and turnips. These vegetables thrive in cooler temperatures and can often be harvested into the winter months. Additionally, greens like spinach and lettuce can also be sown in the fall, as they prefer the milder conditions to grow.
When selecting vegetables, consider your specific hardiness zone within Oklahoma. Most areas fall into USDA zones 6 to 7, which allows for a diverse range of fall crops. It’s important to check the seed packets or local gardening resources for specific planting dates to ensure a successful harvest.
When should I start planting my fall garden in Oklahoma?
In Oklahoma, the best time to start planting your fall garden typically ranges from late July to early September. The exact timing can vary depending on the average first frost date for your specific area. Generally, aim to have your fall crops started at least six to eight weeks before the first expected frost to give them adequate time to mature.
To determine the best planting dates, consult local gardening resources or extension services that provide frost date information for your region. By planting at the right time, you can maximize your chances of a bountiful fall harvest.
How do I prepare my garden soil for fall planting?
Preparing your garden soil for fall planting involves several important steps to ensure it is nutrient-rich and well-aerated. Start by clearing any remaining summer crops or weeds from your garden bed. Once cleared, till the soil to a depth of about 12 inches to enhance aeration. This will help the roots of fall plants to penetrate the soil more easily.
Next, consider adding organic matter to enrich the soil. You can mix in compost, well-rotted manure, or other organic amendments to improve soil fertility. This addition will help retain moisture and provide essential nutrients for your fall crops.
Can I use the same garden space for fall crops as I did for summer crops?
Yes, you can use the same garden space for fall crops that you did for summer crops, but it’s important to consider crop rotation principles. Rotating your crops helps to prevent the buildup of pests and diseases in the soil. For example, if you planted tomatoes in a particular spot during the summer, it’s wise to plant a different type of vegetable, such as brassicas or leafy greens, in that same area for fall.
Also, consider the nutrient requirements of the crops you plan to plant. Some fall vegetables, like legumes, can actually help naturally replenish nitrogen in the soil. By rotating your crops and practicing good garden management, you can keep your soil healthy and productive throughout the growing seasons.
What pests should I watch for in a fall garden in Oklahoma?
In Oklahoma’s fall gardens, common pests to watch for include aphids, cabbage worms, and squash bugs. Aphids can infest a variety of leafy greens and soft-stemmed vegetables, sucking the sap from the plants and potentially transmitting diseases. Cabbage worms can be particularly problematic for brassicas like broccoli and kale, as they feed on the leaves, causing significant damage.
To manage these pests, regularly inspect your plants for signs of infestation. Hand-picking or using organic insecticidal soap can be effective methods for controlling pests without harming beneficial insects. Ensuring proper spacing between plants can also improve air circulation, reducing the likelihood of pest-related issues.
What kind of care do fall garden plants need?
Fall garden plants require diligent care, particularly with respect to watering and mulching. As temperatures drop, it may be easy to overlook watering, but it’s essential to keep the soil consistently moist, especially for newly sown seeds or transplanted seedlings. Regularly check the soil moisture, and make adjustments based on rainfall or temperature fluctuations.
Additionally, applying mulch around your fall crops can provide several benefits. Mulch helps to retain soil moisture, suppress weeds, and moderate soil temperature. This protective layer can be particularly useful during unexpected warm spells that can stress cool-weather plants. Regular monitoring and care throughout the fall growing season will contribute to a healthy and productive harvest.
How can I extend the growing season in my fall garden?
To extend the growing season in your fall garden, consider using row covers or cold frames. These protective structures can trap heat and create a microclimate that allows your plants to thrive in cooler weather. Row covers are lightweight fabrics that can be draped over plants, while cold frames are rigid structures that can house plants and provide additional growing warmth.
Additionally, selecting frost-resistant varieties can also help you maximize your harvest. Some plants, such as certain types of kale and spinach, are known for their ability to withstand cooler temperatures. By combining protective measures with the right crop choices, you can enjoy fresh produce from your garden well into the late fall and early winter months.
