Beets are a versatile, dual-purpose vegetable, offering both a nutritious root and edible greens. Beets thrive in cooler weather, making spring and fall the ideal seasons for their primary growth and harvest. Knowing the practical guidelines for identifying maturity is the best way to ensure optimal flavor and texture from this garden staple.
Determining Harvest Time by Maturity
Most beet varieties reach their horticultural maturity, meaning the roots are ready for harvest, approximately 50 to 70 days after the seeds are sown. This time frame varies based on the specific cultivar, with some faster-growing varieties being ready in as little as 45 days. The goal is to time the planting so that the 50-to-70-day growth period concludes during a period of mild temperatures, as excessive heat can cause the roots to become tough and fibrous. Cooler weather, particularly a light frost in the fall, can actually improve the beet’s flavor by promoting the conversion of starches into sugars.
Gardeners often employ a technique called successive planting, which involves sowing small batches of seeds every two to three weeks. This practice ensures a continuous supply of fresh, tender beets throughout the growing season instead of one large, overwhelming harvest. By staggering the start dates, a gardener can extend the harvest window from early summer right up until the ground freezes in late autumn.
Visual Indicators of Readiness
The most reliable sign of readiness is the physical size of the root, which can be checked by gently brushing away the soil from the top of the plant. Beets are generally considered ready for harvest when their roots have swelled to a diameter between one and three inches. Harvesting within this size range yields the most tender and sweet roots; allowing them to grow larger than three inches often results in a tough, woody texture.
An important visual cue is the emergence of the root’s “shoulder” just above the soil line. When the top portion of the beet is visible, it signals that the root is swelling and approaching the ideal diameter. While healthy, green foliage is necessary for photosynthesis and root development, an excessive amount of yellowing or wilting leaves can indicate that the beet is past its prime or struggling.
Techniques for Harvesting Roots and Greens
Harvesting requires a gentle approach to prevent damage that can lead to color and nutrient loss. Before pulling, loosen the soil around the beet with a garden fork or trowel. Once the soil is loosened, the beet can be grasped at the base of the leaves and gently pulled or twisted out of the ground. Harvesting when the soil is slightly moist makes this process easier and minimizes the risk of breaking the root.
Beet greens can be harvested at any time, even while the root is still developing. To harvest greens selectively, a gardener should only snip one or two outer leaves from each plant, ensuring that the inner leaves remain intact to sustain the root’s growth. After the main root harvest, the greens should be removed immediately, leaving about one inch of the stem attached to the beet root. This small stem stub acts as a seal, which prevents the beet’s internal pigment and moisture from “bleeding” out, preserving its quality.
Post-Harvest Handling and Storage
The first step is trimming the greens, leaving the one-inch stem as a protective barrier. Removing the leaves prevents the root from losing moisture and shriveling, as the greens will continue to draw water from the root if left attached. The roots should then have any excess soil gently brushed off, but they should not be washed unless they are to be used right away, as residual moisture can encourage rot during storage.
For short-term preservation, the unwashed roots can be stored in a plastic bag in the refrigerator’s crisper drawer, where they will keep for approximately two to three weeks. The separate beet greens are highly perishable and should be stored unwashed in a separate plastic bag in the refrigerator, where they will maintain quality for only a few days. For long-term storage, some gardeners pack unwashed beets in a cool, dark, and humid environment, such as a container filled with moist sand or peat moss.
