Step-by-Step Guide to Sowing Giant Sweet Essential Lemon Balm Seeds

Indoor Sowing

1. Prepare Containers: Fill seed trays or small pots with fine, well-draining seed compost.
2. Sowing the Seeds: Lightly press seeds onto the surface of the compost and cover with a thin layer of compost or vermiculite (no more than 1/8 inch).
3. Germination Conditions: Maintain a temperature of 18–21°C (65–70°F). Place in a bright location, such as a sunny windowsill or under grow lights.
4. Watering: Mist gently to keep the compost moist but avoid waterlogging.
5. Germination Time: Seeds typically germinate within 10–15 days under ideal conditions.

Outdoor Sowing

1. Soil Preparation: Choose a sunny or partially shaded spot with well-drained soil. Loosen the soil and enrich it with organic matter or compost.
2. Sowing the Seeds: Scatter seeds thinly over the prepared soil and cover lightly with a fine layer of soil.
3. Watering: Water gently after sowing to help the seeds settle and keep the soil moist during germination.
4. Thinning: Once seedlings are 2–3 inches tall, thin them to 18–24 inches apart to allow room for bushy growth.

Caring for Giant Sweet Essential Lemon Balm Plants

• Watering: Water regularly, keeping the soil evenly moist but not waterlogged. Established plants are relatively drought-tolerant but benefit from consistent moisture.
• Sunlight: Lemon balm thrives in full sun but can tolerate partial shade.
• Fertilising: Generally, lemon balm grows well without additional fertiliser. In poor soil, a light application of balanced herb fertiliser can be applied sparingly.
• Pruning: Regularly pinch off the tips of the plant to encourage branching and prevent legginess. This also delays flowering and extends leaf production.
• Pest Management: Lemon balm is generally pest-resistant but watch for aphids or leaf miners. If necessary, remove affected leaves and apply organic pest control methods.

Harvesting and Using Giant Sweet Essential Lemon Balm

• When to Harvest: Begin harvesting leaves once the plant reaches about 6 inches in height. For the best flavour and aroma, harvest in the morning before the heat of the day.
• Drying Leaves: Harvest before the plant flowers for the most potent leaves. Hang small bunches upside down in a cool, dark, dry place or use a dehydrator to preserve their fragrance.
• Culinary Uses: Use fresh or dried leaves to add a citrusy tang to teas, salads, marinades, and sauces. Lemon balm also works well in herbal remedies for its calming properties.
