When To Plant Beets In Southern California

If you’re a gardener in Southern California, you know our unique climate is a gift. But it can make planting times a bit confusing. Knowing exactly when to plant beets in Southern California is the key to a sweet, bountiful harvest. This cool-season crop thrives when you get the timing just right, avoiding our hotter months.

Beets are incredibly forgiving and fast-growing. They offer both tasty roots and nutritious greens. With a simple plan, you can enjoy multiple harvests throughout the year. Let’s get your beet planting schedule sorted.

For most of Southern California, the best planting times are during the cool seasons. This means late summer through early spring. The goal is to have beets maturing in cool, not cold or hot, weather.

Here’s the simple breakdown for our region:

Late Summer to Fall Planting (Primary Season): Sow seeds from late August through October. This is often the best time. The soil is still warm, which helps germination, and the cooling air temperatures are perfect for root development. You’ll harvest in fall and early winter.
Winter Planting: In our mild coastal and inland valleys, you can plant successively from November through January. Growth slows in the shortest days, but beets will be ready for a late winter or early spring harvest. Avoid planting in heavy, waterlogged soil if we get a very wet year.
Early Spring Planting: Get seeds in the ground from February to early March. This gives beets time to mature before the heat of late spring and early summer arrives. If a sudden heatwave hits, use shade cloth to protect your spring crop.

Avoid planting from late May through July. Hot soil inhibits germination, and the plants will bolt (go to seed) quickly, resulting in poor root development.

Understanding Your Southern California Microclimate

Our region has several distinct climate zones. Your specific location will fine-tune your planting dates.

Coastal (Los Angeles, San Diego, Orange County coasts): You have the longest, most flexible planting window. You can often grow beets year-round with success, though summer plantings may need partial shade.
Inland Valleys & Mild Deserts (San Fernando Valley, Riverside, parts of San Bernardino): Follow the primary schedule closely. Summers are hot, so stick to fall, winter, and early spring. Frost is rare but possible in some inland areas in December/January.
High Desert & Mountain Areas (Victorville, Palmdale, Big Bear): Your season is shorter. Plant in early spring as soon as soil can be worked and again in late summer for a fall harvest. You must avoid hard freezes.

Choosing the Right Beet Varieties

All beets grow well here, but some are particularly suited. Choose varieties based on your taste and the season.

For Fall/Winter Harvests: Try long-season varieties like ‘Cylindra’ or ‘Lutz Winter Keeper’. They store well in the ground.
For Fast Crops in Spring: Opt for quick-maturing types like ‘Early Wonder’ or ‘Red Ace’. They beat the heat.
For Something Different: Don’t overlook golden beets like ‘Touchstone Gold’ or striped ones like ‘Chioggia’. Their flavor is excellent, and they won’t “bleed” like red beets.

Step-by-Step Planting Guide

Follow these steps for a successful start. Beets prefer to be sown directly in the garden where they will grow.

Prepare the Soil: Beets need loose, well-draining soil. Remove rocks and clumps to a depth of at least 12 inches, as obstacles can cause misshapen roots. Work in 2-3 inches of compost. They prefer a slightly sweet soil, so if your soil is very acidic, a light dusting of wood ash can help.
Sow the Seeds: Plant seeds 1/2 inch deep. Space them about 1 inch apart in rows that are 12 inches apart. Each “seed” is actually a cluster, so you will get multiple seedlings. Don’t worry, we’ll thin them later.
Water Gently: Keep the soil consistently moist but not soggy until seedlings emerge, usually in 5-14 days. Using a light layer of straw or compost mulch after they sprout will help retain moisture.

Thinning is Non-Negotiable

This is the most common mistake new beet growers make. If you don’t thin, you’ll get lots of tops and no usable roots.

When seedlings are about 3-4 inches tall, thin them to stand 3 inches apart.
Snip the extras at the soil line with scissors to avoid disturbing the roots of the keepers. Don’t just pull them.
You can eat the thinnings! The tiny leaves are delicious in salads.

Ongoing Care for a Great Harvest

Beets are low-maintenance, but a few key practices ensure plump, sweet roots.

Watering: Provide consistent, even moisture. Fluctuating dry/wet cycles cause cracked roots and make beets taste bitter. About 1 inch of water per week is a good guide, more during hot, dry spells.
Fertilizing: If you prepared soil with compost, little extra is needed. A light feeding with a balanced, organic fertilizer when roots begin to swell can give them a boost. Avoid high-nitrogen fertilizers, which promote leaf growth at the expense of the root.
Weeding: Keep the area weed-free, especially when plants are young. Weeds compete for nutrients and water. Mulching heavily helps suppress them.
Pest Watch: Beets have few pests. Watch for leaf miners (tunnels in leaves) and aphids. Remove affected leaves or spray aphids with a strong stream of water. Row covers at planting can prevent most pest issues.

Harvesting and Storing Your Beets

You can start harvesting whenever you like!

For Greens: Snip a leaf or two from the outside of several plants once they are 4-6 inches tall. Don’t take all the leaves from one plant.
For Baby Beets: Begin pulling roots when they are about 1 inch in diameter. They are incredibly tender and sweet at this stage.
For Full-Size Beets: Most varieties are ready 50-70 days after planting. They’re best when 2-3 inches in diameter. Gently loosen the soil with a fork and pull them up.

After harvesting, twist off the tops, leaving about an inch of stem. This prevents the roots from “bleeding” out in the pan. Store unwashed beets in a plastic bag in the refrigerator for several weeks. They also can be stored in a cool, humid place like a root cellar, or even left in the ground under mulch for weeks in winter.

Common Problems and Simple Solutions

Even experianced gardeners face issues. Here’s how to troubleshoot.

Seeds Didn’t Germinate: Old seeds or soil that dried out are common culprits. Beet seeds lose viability after a few years. Always keep seed beds moist.
Leafy Tops, Small Roots: This means the plants are too crowded (you didn’t thin enough) or the soil has too much nitrogen.
Woody or Tough Roots: The plants are either over-mature or they experienced uneven watering, especially a dry period followed by heavy watering.
Scabby or Rough Patches on Roots: This is scab, often caused by soil that is too alkaline. Adding compost and ensuring consistent moisture can help prevent it next time.

FAQ: Planting Beets in Southern California

Can I plant beets in the summer in SoCal?
It’s not recommended. High temperatures cause poor germination, bolting, and bitter, small roots. Stick to the cooler months for the best results.

How often should I water my beet plants?
Aim for deep, consistent watering about 2-3 times per week, depending on weather. The goal is 1 inch of water weekly, keeping the soil evenly moist like a wrung-out sponge.

What are the best companion plants for beets?
Beets grow well near bush beans, lettuce, onions, and members of the cabbage family. Avoid planting them too close to pole beans, as they can compete.

Can I grow beets in containers?
Absolutely. Choose a pot at least 12 inches deep and wide. Use a quality potting mix and ensure the container has good drainage. You’ll need to water more frequently than in-ground plants.

Why are my beet leaves turning yellow?
Yellowing lower leaves can be a sign of overwatering or a nitrogen deficiency. Check your soil moisture first. If the soil is soggy, cut back on water. If it’s dry and the plant is stunted, a light nitrogen feed might help.

Getting your beet planting timing correct in Southern California opens the door to an easy and rewarding harvest. By following these simple guidelines for our cool seasons, you’ll be enjoying homegrown, sweet beets from your own garden in no time.
