Growing Chicory for Roots
Chicory, known for its deep taproots and bitter-tasting leaves, is a plant that rewards the gardener with a variety of uses including as a coffee substitute. Growing chicory for its roots involves careful planning, appropriate maintenance, and strategic harvesting to ensure a successful crop.
Planning and Planting
When planting chicory for its roots, selecting the right site and time are crucial. The plant prefers a full sun location with well-draining soil. It is advisable to begin with quality seeds, planting them in the spring after the threat of frost has passed. For optimal growth, the seeds should be sown at a depth of around 1/4 to 1/2 inch with spacing of about 6-8 inches between plants. This allows each chicory plant enough space to develop robust roots.
Maintenance and Care
Once seeds have germinated, maintenance includes regular watering to keep the soil evenly moist, but not waterlogged. Overwatering or poor drainage can lead to root rot. Mulching can help retain soil moisture and control weeds, which compete for nutrients. Thinning young chicory plants can prevent overcrowding and promote healthier root development.
Harvesting and Regrowth Strategies
To harvest the roots, one should wait until the foliage is mature (usually when leaves reach 12-18 inches in height). For a consistent supply, chicory can be harvested progressively. One popular method is to dig out the entire plant, carefully removing it from the soil to keep the taproot intact. After harvesting, the root can be cut, leaving a small portion above ground, and replanted to encourage regrowth, potentially yielding a more tender crop the following season. For continued use, the roots may also be stored in a cool, dry place until ready for replanting or use.
Cultivating Chicory for Greens
Cultivating chicory for greens involves selecting the right varieties, understanding blanching techniques, and knowing when to harvest the leaves and flowers for optimal flavor and texture.
Selecting Varieties for Leaves
When cultivating chicory for its greens, one should choose varieties known for their leaf production. Witloof, also known as Belgian endive, is highly prized for its blanched heads. For those who prefer loose-leaf varieties, curly endive and Italian dandelion are excellent choices. Both are known for their robust flavor profile, with Italian dandelion offering longer, slightly bitter leaves. Sweet and sugarloaf types are valued for their less bitter, sweeter tasting leaves, making them a popular option for fresh salads.
Blanching Techniques
Blanching is a crucial process to reduce bitterness and produce tender, pale greens, often found in witloof chicory. To blanch, one can cover the plant with a dark, opaque material or by heaping soil around the base of the plant, ensuring that light is prevented from reaching the leaves for about two weeks before the intended harvest. This process leads to blanched leaves that are milder in flavor and desirable in culinary applications.
Harvesting Leaves and Flowers
The leaves of the chicory plant are typically ready to harvest when they reach a height of 12 to 18 inches. For maximizing flavor and tenderness, it is advised to harvest in the morning when the leaves are crisp and full of moisture. Chicory flowers, which present brilliant blue blossoms, can be plucked as soon as they open and add a decorative touch to dishes. However, the primary focus for leaf production is often the foliage rather than the flowers.
