Bee balm (Monarda species) is a versatile North American perennial prized for its aromatic foliage and unique, colorful flowers. This plant is a member of the mint family (Lamiaceae) and is commonly used in medicinal teas, as a culinary spice, and for ornamental beauty. Determining the best time to harvest depends on which part of the plant you intend to use and what properties you wish to maximize.
Harvesting Leaves for Peak Potency
Bee balm leaves should be harvested before the plant begins to flower for maximum flavor and potency. This timing is crucial because the concentration of aromatic essential oils, such as thymol, is highest just prior to the bloom cycle. Once the plant expends energy producing flowers, the oil content within the leaves declines.
A practical indicator for peak leaf potency is when the plant reaches 12 to 18 inches tall, or when flower buds have formed but have not yet opened or shown color. Harvesting at this stage ensures the strongest flavor profile, often resembling a blend of oregano and mint. Collect the foliage in the morning after the dew has evaporated but before the intense heat causes volatile oils to dissipate.
Timing the Harvest for Flowers
When harvesting the flowers, the timing shifts to the plant’s full bloom period. Unlike the leaves, flowers are best collected when they are fully open, vibrant, and visually appealing. This usually occurs during mid to late summer, depending on the region and the specific variety.
The flowers are sought after primarily for their appearance and subtle flavor, making them excellent for culinary garnishes, colorful herbal teas, or for infusing into tinctures. Harvesting at peak bloom ensures maximum color retention and visual appeal after drying. Select the freshest, most vibrant heads, leaving any faded or browning blooms on the plant.
Proper Cutting Techniques to Encourage Regrowth
Successful harvesting involves a specific cutting technique that promotes the plant’s health and encourages a second flush of growth. Treating the harvest as pruning is the most effective approach for maintaining a robust perennial. Always use sharp, clean shears or scissors to make clean cuts that minimize damage to the stem tissue.
The cut should be made just above a leaf node, the point on the stem where leaves are attached. Cutting above this node stimulates dormant buds to break, causing the stem to branch out and produce new growth. Leave at least one-third to one-half of the original plant height intact to ensure enough foliage remains for continued photosynthesis.
Removing too much of the plant can stress it and inhibit its ability to recover and regrow. This method, sometimes called a “Chelsea Chop,” helps maintain a compact, bushy form and can lead to a second, smaller round of flowering later in the season. Consistent, selective harvesting provides a continuous supply of herbs and improves air circulation, reducing the plant’s susceptibility to powdery mildew.
Drying and Storing Bee Balm
After harvesting, proper drying and storage are necessary to preserve the herb’s color, flavor, and aromatic compounds. The primary condition for drying is a cool, dark, and well-ventilated environment, ideally around 70°F. This helps prevent the degradation of essential oils caused by direct sunlight without compromising herbal quality.
One common method involves gathering stems into small bunches and hanging them upside down in a sheltered location until the leaves become brittle. Alternatively, strip the leaves and flowers from the stems and spread them in a single layer on fine-mesh screens, or use a food dehydrator set to a low, herb-specific temperature. The herb is fully dry when the leaves crumble easily when rubbed between your fingers.
Once the material is completely dry (which can take one to three weeks depending on humidity), transfer it to airtight containers. Glass jars or opaque containers are preferred to protect the contents from light exposure, which causes the herb to lose potency. Stored correctly in a cool, dark pantry, dried bee balm retains its strength and flavor for 12 to 18 months.
