When To Plant Beets In Missouri

If you’re planning your garden in the Show-Me State, knowing when to plant beets in Missouri is the key to a sweet, crunchy harvest. Getting the timing right means you’ll enjoy tender roots and delicious greens from your own backyard.

Beets are a fantastic crop for Missouri gardeners. They’re relatively easy to grow, tolerate cooler weather, and give you two harvests in one—the roots and the leafy tops. This guide will walk you through the best planting windows for spring and fall, along with simple tips for success.

Missouri’s climate, with its distinct seasons, allows for two main beet planting periods: spring and fall. The goal is to grow beets during the cooler parts of the year, as hot summer temperatures can make them tough and bitter.

Spring Planting Window

For a spring harvest, you need to get your seeds in the ground early. Beet seeds can germinate in cool soil, and the seedlings can handle a light frost.

Best Time to Sow: Plant your beet seeds directly in the garden 2 to 4 weeks before your last average spring frost date.
Date Range: This typically falls between mid-March and mid-April across Missouri. In southern zones, you can start as early as late February. In northern areas, aim for early to mid-April.
Soil Check: The soil should be workable—not frozen or a muddy clump. If you can squeeze a handful and it crumbles easily, it’s ready.

Fall Planting Window

Fall is often the best time for growing beets in Missouri. The cooling temperatures create ideal conditions for developing sweet, tender roots.

Best Time to Sow: Plant your seeds about 8 to 10 weeks before your first average fall frost date.
Date Range: This usually means planting from late July through late August. A succesful fall crop can often be harvested right up until the ground freezes.
Heat Consideration: For late summer planting, provide some afternoon shade or use a light mulch to keep the soil cooler for germination.

Understanding Missouri’s Growing Zones

Missouri spans USDA hardiness zones 5b to 7a. This affects your exact planting dates:

Zone 5 (North Missouri): Last spring frost around April 20-30. First fall frost around October 10-20. Plant spring beets in early April. Plant fall beets in early August.
Zone 6 (Central Missouri): Last spring frost around April 10-20. First fall frost around October 17-27. Plant spring beets in late March to early April. Plant fall beets in mid-August.
Zone 7 (South Missouri): Last spring frost around April 1-10. First fall frost around October 25 – November 5. Plant spring beets in mid-March. Plant fall beets in late August.

How to Plant Beets for Success

Following a few simple steps at planting time will give your beets a strong start.

1. Choose the Right Location

Beets need full sun, at least 6 hours of direct sunlight daily. They prefer loose, well-draining soil. If your soil is heavy clay, amend it with compost to improve texture. Remove rocks and clumps, as they can cause misshapen roots.

2. Prepare Your Soil

Beets are moderate feeders. Work in a 2-inch layer of compost or well-rotted manure before planting. Avoid high-nitrogen fertilizers, which promote leafy tops at the expense of root development. A soil pH between 6.0 and 7.0 is ideal.

3. Sowing Seeds Correctly

Beet “seeds” are actually small fruit clusters that contain multiple seeds. This is why you often get several seedlings from one planting.

Make a shallow furrow about 1/2 inch deep.
Sow seeds 1 inch apart. You can space rows 12 to 18 inches apart.
Cover lightly with soil and pat down gently.
Water thoroughly but gently to avoid washing seeds away.

4. Early Care and Thinning

Keep the soil consistently moist for germination, which takes 5 to 14 days. Once seedlings are 3 to 4 inches tall, you must thin them. This is crucial for good root size.

Thin seedlings to stand 3 to 4 inches apart. You can eat the thinned greens in salads!
Mulch around plants to retain moisture and suppress weeds.
Water regularly, providing about 1 inch of water per week if rain is lacking.

Tips for a Extended Harvest

You don’t have to plant all your beets at once. For a continuous supply, practice succession planting.

In spring, sow a new batch of seeds every 2 to 3 weeks until late spring.
In fall, you can make two sowings: one in late July and another in mid-August.
Some varieties, like ‘Early Wonder’, mature faster (50 days) than others like ‘Cylindra’ (60 days). Staggering varieties also spreads out your harvest.

Common Problems and Simple Solutions

Even with good timing, a few issues can pop up. Here’s how to handle them.

Slow or Poor Germination

Old seeds or crusted soil can cause this. Soak seeds in water for 12-24 hours before planting to soften the seed coat. After sowing, cover the row with a damp burlap sack or board to retain moisture; remove it as soon as sprouts appear.

Leaf Miners or Flea Beetles

These pests can damage the foliage. Use floating row covers to protect young plants. For leaf miners, pick off and destroy affected leaves. Healthy plants can usually outgrow minor pest damage.

Small or Woody Roots

This is often caused by overcrowding (not thinning), irregular watering, or planting too late in warm weather. Stick to your planting schedule, thin diligently, and keep the water consistent.

Harvesting and Storing Your Beets

You can start harvesting beet greens when they are young and tender. For the roots, they are ready when they are about 1.5 to 3 inches in diameter, depending on the variety.

Loosen the soil with a garden fork and gently pull up the plant.
For storage, twist off the tops, leaving about an inch of stem. Don’t cut the tail root.
Store unwashed beets in a plastic bag in the refrigerator crisper for several weeks. For long-term storage, they can be kept in a cool, humid root cellar.

Frequently Asked Questions (FAQ)

Can you plant beets in the summer in Missouri?

It’s not generally recommended. Summer heat stresses the plants, leading to poor root development and a bitter flavor. Focus on spring and fall plantings for the best results.

What are the best beet varieties for Missouri?

Many do well! Reliable choices include ‘Detroit Dark Red’ (great all-purpose), ‘Golden’ (doesn’t bleed), ‘Chioggia’ (candy-striped interior), and ‘Lutz Green Leaf’ (good for storage).

How long do beets take to grow?

Most beet varieties are ready to harvest 50 to 70 days after planting the seeds. You can check their size by brushing aside soil at the shoulder of the root.

Can I start beets indoors?

It’s possible but tricky, as beets don’t like their roots disturbed. Direct sowing is almost always the better and easier method for home gardeners.

By following these timing guidelines and care tips, you’ll be well on your way to a plentiful beet harvest. Remember, the secret is in the cool weather. With a little planning for spring and fall, you can enjoy homegrown beets for much of the year. There’s nothing quite like the taste of a beet you’ve grown yourself, pulled fresh from Missouri soil.
