Growing lemon verbena from seed can be a bit challenging and time-consuming compared to starting with a small plant. However, it is not impossible and can be a rewarding experience for those who are patient and dedicated to the process.
To start growing lemon verbena from seed, you will need to obtain fresh seeds from a reliable source. It is important to note that lemon verbena seeds have a relatively low germination rate, so it is recommended to sow more seeds than you actually need to increase your chances of success.
Before sowing the seeds, prepare a seed-starting tray or small pots with a well-draining potting mix. You can improve the soil’s drainage by adding perlite or vermiculite to the mix. Moisten the soil slightly before sowing the seeds.
Gently press the lemon verbena seeds into the soil, but do not cover them completely as they require light to germinate. Place the tray or pots in a warm and bright location, such as a sunny windowsill or under grow lights.
Maintain consistent moisture in the soil by misting it regularly or using a bottom watering method. Avoid overwatering, as excessive moisture can lead to damping off or root rot. It is crucial to keep the soil moist but not waterlogged.
Germination of lemon verbena seeds can be slow and sporadic, taking anywhere from 2 weeks to several months. Be patient and continue to provide the seeds with the appropriate conditions for growth.
Once the seedlings have emerged, ensure they receive ample sunlight or provide artificial grow lights to promote healthy growth. As the seedlings grow, thin them out to allow proper spacing between plants. This will prevent overcrowding and promote good air circulation, reducing the risk of diseases.
Transplant the seedlings into larger pots or the garden when they have developed a few sets of true leaves and the weather has warmed up. Lemon verbena prefers full sun, so choose a location that receives at least 6-8 hours of direct sunlight daily.
When transplanting, ensure the soil in the new location has been amended with compost to improve its fertility and drainage. Avoid heavy clay or overly wet soils, as they can lead to root rot. If necessary, consider adding organic matter or sand to improve the soil texture.
Regularly water the lemon verbena plants, providing enough moisture to keep the soil evenly moist but not waterlogged. Mulching around the base of the plants can help retain moisture and suppress weed growth.
Prune the lemon verbena plants regularly to promote bushier growth and to harvest the fragrant leaves for culinary or aromatic purposes. Pinch off the tips of the stems to encourage branching and remove any dead or damaged foliage.
In colder regions, lemon verbena may not survive the winter outdoors. Consider bringing potted plants indoors or take cuttings to propagate new plants for the following year.
While growing lemon verbena from seed may be more challenging and time-consuming than starting with a small plant, it is certainly possible with patience and proper care. However, for those looking for an easier and quicker option, starting with a small plant is recommended.
