If you’re planning your Oklahoma garden, knowing when to plant beets is key to a great harvest. This guide covers the best planting times for beets in our state, helping you get your timing just right.
Beets are a fantastic crop for Oklahoma. They handle our climate well and give you both tasty roots and nutritious greens. With two main planting seasons, you can enjoy them for much of the year.
When to Plant Beets in Oklahoma – Best Planting Times for
The ideal times to plant beets in Oklahoma are during the cool seasons of spring and fall. Beet seeds germinate best in soil temperatures between 50°F and 85°F. They grow sweetest roots when they mature in cool weather.
Spring Planting Schedule
For a spring harvest, you need to get your seeds in the ground early. The goal is to have beets mature before the intense summer heat arrives, which can make them woody and bitter.
- Optimal Window: Plant from mid-February through late March.
- Southern Oklahoma: You can start as early as late January if the winter is mild.
- Northern Oklahoma: Aim for early to mid-March to avoid a late freeze.
- Pro Tip: Use a soil thermometer. Once soil is workable and around 45°F, you can sow.
Fall Planting Schedule
Fall is often the easiest and most productive time for growing beets in Oklahoma. The cooling temperatures are perfect for sweet, tender roots.
- Optimal Window: Plant from mid-August through early October.
- Key Calculation: Count back 6 to 8 weeks from your first average fall frost date. This gives beets enough time to size up.
- Statewide Frost Dates: First frost typically occurs between late October (north) and mid-November (south).
Understanding Your Oklahoma Growing Zone
Oklahoma spans zones 6a to 8a. This affects your exact planting dates. Check your zone to fine-tune your schedule.
- Zones 6a & 6b (North): Spring plant mid-March. Fall plant early August.
- Zone 7a & 7b (Central): Spring plant early March. Fall plant late August.
- Zone 8a (South): Spring plant late February. Fall plant mid-September.
Step-by-Step Planting Guide
Follow these steps for success from seed to harvest.
1. Preparing Your Soil
Beets need loose, well-draining soil. Hard, compacted clay will cause misshapen roots.
- Work the soil to a depth of at least 8-10 inches.
- Mix in 2-3 inches of compost or aged manure.
- Remove rocks and clumps to allow roots to expand easily.
- Aim for a slightly sweet soil pH of 6.0 to 7.0.
2. How to Sow Beet Seeds
Beet “seeds” are actually dried fruit clusters containing multiple seeds. This means you’ll often get several seedlings from one planting.
- Create rows about 12-18 inches apart.
- Plant seeds 1/2 inch deep.
- Place a seed cluster every 1-2 inches.
- Cover lightly with soil and pat down gently.
- Water thoroughly but softly to avoid washing seeds away.
3. Thinning Your Seedlings
This is a crucial step many gardeners skip. Overcrowded beets won’t form good roots.
- When seedlings are 3-4 inches tall, thin them.
- Use scissors to snip off extras at the soil line. This avoids disturbing the roots of the keepers.
- Leave the strongest seedlings spaced 3-4 inches apart.
- Don’t throw away the thinnings—they make excellent salad greens!
Essential Care Tips for Oklahoma Beets
Watering Wisely
Consistent moisture is vital, especially during root development. Inconsistent watering leads to cracked or tough beets.
- Provide 1 inch of water per week from rainfall or irrigation.
- Water deeply to encourage deep roots.
- Use mulch! A 2-inch layer of straw or shredded leaves keeps soil cool, retains moisture, and suppresses weeds.
Fertilizing for Success
Beets are moderate feeders. To much nitrogen gives you huge leaves but tiny roots.
- At planting, use a balanced organic fertilizer (like a 5-5-5).
- Side-dress with a low-nitrogen, phosphorus-rich fertilizer when roots begin to swell.
- Avoid fresh manure, as it can cause forked roots.
Pest and Disease Management
Beets have few serious problems, but stay vigilant.
- Leaf Miners: Look for squiggly white lines on leaves. Remove affected leaves.
- Flea Beetles: They create small holes in leaves. Use row covers as a barrier.
- Cercospora Leaf Spot: Shows as small brown spots with purple edges. Ensure good air circulation and avoid overhead watering.
Harvesting and Storing Your Bounty
You can start harvesting beets when they are the size of a golf ball. These “baby beets” are incredibly tender.
- For full-sized roots, harvest when they are 1.5 to 3 inches in diameter (check the seed packet for variety specifics).
- Loosen the soil with a fork and gently pull them up.
- Don’t forget the greens! Harvest a few leaves from each plant while they’re growing, but leave enough to support the root.
- For storage, twist off the tops, leaving about an inch of stem. Store unwashed roots in a cool, humid place like your refrigerator crisper drawer.
Recommended Beet Varieties for Oklahoma
Some varieties perform exceptionally well in our conditions.
- Detroit Dark Red: A reliable, classic variety with excellent flavor.
- Chioggia: Beautiful red and white interior rings. Tolerates heat fairly well.
- Golden Beet: Sweet, doesn’t bleed, and its greens are less prone to leaf spot.
- Cylindra: Long, cylindrical roots are perfect for slicing and can be planted closer together.
FAQ: Planting Beets in Oklahoma
Can I plant beets in the summer in Oklahoma?
It’s not recommended. Summer heat stresses the plants, causing poor root development and bitterness. For a summer harvest, you would need to plant very early in spring.
How long do beets take to grow?
Most beet varieties are ready for harvest 50 to 70 days after planting. You can always pick them earlier for smaller, more tender beets.
Can I grow beets in containers?
Absolutely. Choose a pot at least 12 inches deep. Use a quality potting mix and ensure it has good drainage. Varieties like ‘Little Ball’ are well-suited for containers.
Why are my beet roots small but leaves huge?
This usually indicates to much nitrogen in the soil or overcrowding. Next time, use a balanced fertilizer and remember to thin your seedlings properly.
Can I do succession planting with beets?
Yes! To extend your harvest, sow a new short row every 2-3 weeks during your spring or fall planting windows. This gives you a continuous supply instead of one giant harvest.
By following these timing and care guidelines, you’ll be well on your way to a succesful beet crop. The key is working with Oklahoma’s seasons, not against them. With a little planning, you can enjoy homegrown beets from your own garden for months.
