Thyme is an herb with antibacterial, antioxidant, and anti-inflammatory properties. It is often used for respiratory treatments, and it boosts the immune system and fights infections. How to plant: Plant thyme in a location that gets full sunlight with well-drained soil. Ensure the soil isn't too wet and allow space for the plants to grow. Germination Time: Thyme seeds usually germinate in 14-21 days. Plant the seeds indoors or outdoors in late spring after the risk of frost has passed.
