Growing Instructions
Starting your seeds
You can start Spearmint seeds indoors using a heat mat to encourage germination. Once the seedlings sprout and grow a few sets of leaves, move them outdoors. Keep the soil moist and provide 4–6 hours of sunlight daily. When direct sowing Spearmint seeds, plant them about 1/4 inch deep in well-drained soil, spacing them 12–18 inches apart to give them plenty of room to grow.
Harvesting your seeds
To harvest spearmint snip the stems just above a set of leaves, promoting bushier growth. Use clean scissors or pruning shears to cut the leaves. Frequent harvesting encourages fresh growth and maintains the plant's flavor.
