| Plug Care | Transplant plugs as soon as possible after arrival to ensure proper establishment. Water thoroughly after planting and maintain consistent moisture until the plants are established. |
| Netting / Staking | Not necessary; plants have sturdy stems that typically do not require support. |
| Temperature Range | Hardy in USDA zones 4-8; tolerates a range of temperatures but prefers moderate climates. |
| Spacing | Space plants 12 inches apart to allow for adequate air circulation and growth. |
| Soil Preference | Prefers well-draining, fertile soils but is adaptable to various soil types, including clay and sandy soils. |
| Day Length | Not daylight sensitive. Thrives in full sun to partial shade, with more flowers produced in sunnier locations. |
| Pinching | Not required; however, pinching back young growth can encourage bushier plants. |
| When to Plant | Transplant plugs outdoors in spring after the last frost or in early fall to allow establishment before winter. |
| Harvesting | Harvest stems when the foliage is mature and the flowers have opened for the longest vase life. |
| Post Harvest Care | To use as a fresh floral filler, cut stems should immediately be placed into a bucket of cool water and left in a cool area to hydrate and condition before use. For drying, hang harvested stems upside down in a cool, dry, and well-ventilated area until completely dry. |
| Diseases / Insects | Generally pest-free; may occasionally encounter leaf spot or powdery mildew. Ensure good air circulation and avoid overhead watering to minimize risk. |
| Bailey's Notes | Clustered Mountain Mint is a versatile and low-maintenance perennial that attracts a variety of pollinators, including bees and butterflies. Its aromatic foliage releases a minty scent when brushed or crushed, adding sensory appeal to floral arrangements. While it prefers moist soils, once established, it can tolerate short periods of drought. Although it's considered a mint and it does spread via rhizomes, it is nowhere near as aggressive as real mint. Regularly dividing the plants every few years in early spring helps maintain vigor and increases your stock. |
