Lemon Verbena Plugs - Key Growing Information
SOWING: Transplant (recommended): If you will be selling the herbs in containers with a relatively quick turnaround (a month or two), 4" diameter pots are a popular option. Plant one plug per pot and grow on in a protected environment until the plants become established. Water and fertilize as needed. For larger containers, plant one to three plugs per 12" diameter pot. If you will be transplanting to the field, space plants 18" apart.
INSECT PESTS AND DISEASES: Perennial herbs are typically hardy, easy to grow plants that have few problems with insects and disease. Foliar and root diseases can be prevented with adequate air flow and well-drained soil. If foliar disease or pest problems occur, treat the plants with an appropriate fungicide, such as OxiDate®, or insecticide, such as Pyganic®. Be sure to follow the application instructions indicated for herbs.
LIGHT PREFERENCE: Sun.
SOIL REQUIREMENTS: Well-drained soil that is neutral to slightly acidic (pH of 6.1-7.0). Prior to planting, check your soil pH and adjust if necessary. Loosen the soil and work in compost or a balanced fertilizer. It is best to make sure that your planting area is weed-free prior to transplanting. Control weeds after transplanting with shallow cultivation or mulch.
PLANT HEIGHT: 24-48".
PLANT SPACING: 18".

HARVEST: Wait until the plants are well established prior to harvesting significant amounts. To avoid stressing the plants when harvesting large quantities, keep them well-watered, use sharp sterilized shears, and harvest in the early morning.
