If you are looking for the best vegetables to grow in missouri fall, you have come to the right place. The cool autumn weather in Missouri is perfect for many veggies that actually taste sweeter after a light frost. This guide will help you pick the right crops and get them in the ground at the right time.
Fall gardening in Missouri is a bit different than spring. You need to think about first frost dates, which vary from early October in the north to late October in the south. The key is to plant early enough so your veggies can mature before the really cold weather hits. Let’s look at what grows best and how to make your fall garden a success.
Best Vegetables To Grow In Missouri Fall
When you think about fall veggies, think about crops that love cool weather. These plants do not mind a little chill and some even get better after a frost. Here are the top picks for your Missouri fall garden.
Broccoli And Cauliflower
Broccoli and cauliflower are stars of the fall garden. They need about 60 to 80 days to mature, so you should plant them in late July or early August. The cool fall weather helps them form tight, tasty heads. You can start seeds indoors or buy transplants from a garden center.
These plants like rich soil and plenty of water. Mulch around them to keep the soil cool and moist. Watch out for cabbage worms, which can be a problem in early fall. Use row covers to protect your plants from pests and light frosts.
Planting Tips For Broccoli And Cauliflower
- Plant in full sun with well-drained soil
- Space plants 18 to 24 inches apart
- Water deeply once a week
- Harvest when heads are firm and tight
Leafy Greens Like Spinach And Kale
Spinach and kale are super easy to grow in the fall. They can handle light frosts and even taste better after a cold snap. Spinach matures in about 40 to 50 days, while kale takes a bit longer. Plant them in late August or early September for a steady harvest.
You can pick the outer leaves of kale as the plant grows, giving you fresh greens for weeks. Spinach grows quickly and you can harvest the whole plant or just the outer leaves. Both are packed with vitamins and are great in salads or cooked dishes.
Growing Leafy Greens
- Prepare soil with compost or aged manure
- Sow seeds 1/2 inch deep and 2 inches apart
- Thin seedlings to 6 inches apart
- Water regularly to keep soil moist
- Harvest leaves when they are 4 to 6 inches tall
Root Vegetables Like Carrots And Beets
Carrots and beets are perfect for fall because they store well in the ground. They need about 60 to 70 days to mature. Plant them in early August so they have time to grow before the ground freezes. The cool weather makes them sweeter and more tender.
Carrots need loose, sandy soil to grow straight. Beets are more forgiving and can handle heavier soil. Both crops benefit from a thick layer of mulch to protect them from temperature swings. You can leave them in the ground after the first frost and harvest as needed.
Tips For Root Vegetables
- Plant seeds directly in the garden
- Thin carrots to 2 inches apart
- Thin beets to 3 inches apart
- Keep soil evenly moist for best growth
Brassicas Like Cabbage And Brussels Sprouts
Cabbage and Brussels sprouts are classic fall crops. Cabbage matures in about 70 to 80 days, while Brussels sprouts take longer, up to 100 days. Plant them in mid-summer for a fall harvest. The cold weather actually improves the flavor of Brussels sprouts.
These plants need plenty of space and nutrients. Use a balanced fertilizer when planting and side-dress with compost mid-season. Watch for aphids and caterpillars. Row covers can help keep pests away and extend your growing season.
Caring For Brassicas
- Plant in fertile, well-drained soil
- Space cabbage 12 to 18 inches apart
- Space Brussels sprouts 24 inches apart
- Water consistently to prevent splitting
- Harvest cabbage when heads are firm
- Pick Brussels sprouts from the bottom up
Peas And Beans
Peas and some beans can be grown in the fall, but you need to choose the right varieties. Snow peas and sugar snap peas are good choices because they mature quickly, in about 50 to 60 days. Plant them in early August for a fall harvest.
Bush beans can also work if you plant them by mid-August. They need warm soil to germinate, but the cooler weather later on helps the pods develop. Keep the soil moist and pick pods regularly to encourage more growth.
Growing Peas And Beans In Fall
- Choose quick-maturing varieties
- Plant seeds 1 inch deep and 2 inches apart
- Provide support for climbing peas
- Water at the base to prevent disease
When To Plant Fall Vegetables In Missouri
Timing is everything for a successful fall garden. You need to know your first frost date and count backwards from there. In northern Missouri, the first frost is usually around October 10. In central Missouri, it is around October 20. In southern Missouri, it is around October 30.
Most fall vegetables need 60 to 80 days to mature. So, if you live in the north, you should plant by early August. In the south, you have until mid-August or even late August for quick crops. Always check the seed packet for days to maturity and add a week or two for safety.
Using A Fall Planting Calendar
A fall planting calendar can help you stay on track. Here is a simple guide based on Missouri’s average frost dates.
- Late July: Plant broccoli, cauliflower, cabbage, Brussels sprouts
- Early August: Plant carrots, beets, peas, bush beans
- Mid-August: Plant spinach, kale, lettuce, radishes
- Late August: Plant turnips, Swiss chard, mustard greens
Remember that these dates are averages. You can push the planting a bit later if you use row covers or cold frames to protect your plants from early frosts.
Preparing Your Soil For Fall Vegetables
Good soil is the foundation of a great garden. After your summer crops are done, you need to refresh the soil for fall planting. Remove any old plants and weeds. Add a 2 to 3 inch layer of compost or well-rotted manure and work it into the top 6 inches of soil.
Fall vegetables need plenty of nitrogen for leafy growth and phosphorus for root development. A balanced fertilizer like 10-10-10 can help. Test your soil pH and aim for a range of 6.0 to 7.0. Most vegetables grow best in slightly acidic to neutral soil.
Improving Drainage And Structure
Missouri soil can be heavy clay in some areas. If your soil drains poorly, consider building raised beds. They warm up faster in the fall and provide better drainage. You can also add organic matter like leaf mold or peat moss to improve soil structure.
Mulch is your friend in the fall garden. It helps keep the soil cool, retains moisture, and suppresses weeds. Use straw, shredded leaves, or grass clippings. Apply a 2 to 3 inch layer around your plants after they are established.
Watering And Fertilizing Fall Crops
Fall weather in Missouri can be unpredictable. Some years are dry, while others are wet. Water your fall vegetables deeply once a week if there is no rain. The soil should be moist but not waterlogged. Overwatering can lead to root rot and other diseases.
Fertilize your crops lightly every 3 to 4 weeks. Use a liquid fertilizer or side-dress with compost. Leafy greens need more nitrogen, while root crops need more phosphorus. Follow the instructions on the fertilizer package to avoid burning your plants.
Dealing With Pests And Diseases
Fall gardens have fewer pests than spring gardens, but you still need to watch out. Aphids, cabbage worms, and slugs can be problems. Check your plants regularly and remove any pests by hand. Use insecticidal soap for aphids and diatomaceous earth for slugs.
Diseases like powdery mildew and downy mildew can occur in cool, wet weather. Space your plants properly to allow good air circulation. Water at the base of the plants to keep the leaves dry. Remove any infected leaves immediately to prevent the disease from spreading.
Extending Your Fall Growing Season
You can keep your fall garden going longer with a few simple tools. Row covers are lightweight fabric that protects plants from frost and pests. They let in light and water while keeping the cold out. You can use them on hoops or directly on the plants.
Cold frames are another option. They are like mini greenhouses that trap heat from the sun. You can build one with old windows and lumber or buy a kit. Cold frames can extend your season by 4 to 6 weeks, allowing you to harvest fresh vegetables into December.
Using Mulch For Frost Protection
A thick layer of mulch can protect root vegetables from freezing. After the first frost, cover your carrots, beets, and parsnips with 6 to 8 inches of straw or leaves. You can then harvest them as needed throughout the winter. The mulch keeps the ground from freezing solid.
For leafy greens, use a floating row cover. It adds a few degrees of warmth and can protect plants down to 28°F. Remove the cover during the day if temperatures rise above 50°F to prevent overheating.
Harvesting And Storing Fall Vegetables
Harvest your fall vegetables at the right time for the best flavor. Broccoli and cauliflower should be picked when the heads are tight and before they start to flower. Cabbage is ready when the heads are firm and solid. Leafy greens can be harvested as soon as the leaves are large enough to eat.
Root vegetables like carrots and beets can be left in the ground for weeks after they mature. They actually get sweeter after a light frost. Just cover them with mulch to prevent freezing. You can also store them in a cool, dark place like a root cellar or basement.
Storing Tips For Fall Crops
- Remove tops from root vegetables before storing
- Store carrots and beets in damp sand or sawdust
- Keep leafy greens in the refrigerator in a plastic bag
- Store cabbage and Brussels sprouts in a cool, humid place
Common Mistakes To Avoid
Even experienced gardeners make mistakes with fall gardens. Here are some common ones to watch out for.
- Planting too late: Count back from your first frost date
- Using too much nitrogen: It can cause lush leaves but poor roots
- Ignoring pests: Fall pests can still damage your crops
- Overwatering: Cool weather means less evaporation
- Not mulching: Mulch helps regulate soil temperature
By avoiding these mistakes, you can have a productive fall garden that provides fresh vegetables well into the winter.
