Basil Seeds,
Lime

Lime basil is a warm-weather herb that should be planted after all risk of frost has passed and nighttime temperatures consistently stay above 50 F. This typically means planting in late spring or early summer, depending on your region. If you're uncertain about your frost-free dates, check out our blog post, 'Our Experts Answer Questions, Share Resources.' The best temperature for optimal growth is 70-85 F.

Basil Lime seeds indoors 4 to 6 weeks before your last expected frost date. Sow seeds 1/4 inch deep in a well-draining seed-starting mix and keep the soil consistently moist. Place the seed trays in a warm location with temperatures between 70 to 85°F. Seeds will germinate in 6 to 10 days. Transplant outdoors when the weather is suitable, spacing 8 to 12 inches apart. In long-summer areas, you can also direct sow outdoors, later thinning to the proper spacing.

Water at the base of the plant to keep the foliage dry and prevent fungal issues. Apply mulch to retain soil moisture and suppress weeds. Fertilize the plants with a balanced, organic fertilizer every 2 to 4 weeks for better growth. Regularly pinch off flowers as soon as they appear to encourage the plant to focus on leaf production. Lime basil is well-suited for container gardening and can also be planted alongside companion plants such as tomatoes to repel pests and enhance flavor. Harvest frequently to keep the plant productive and bushy.

• Flower heads mature progressively from the bottom of the stem to the top.
• When the bottom seed head starts to turn brown, the stem can be cut and allowed to dry away from direct sun in a well-ventilated area.
• Rub dried raceme over a fine wire mesh and winnow off the chaff.
• Place chaff in a bowl and carefully swirl contents around. Seeds will gather at the bottom of the bowl.
• Tip the bowl so that the chaff can be discarded and blow the rest out carefully.
