Basil Seeds,
Lemon

Start Lemon basil seeds indoors 4-6 weeks before the last frost date in your area, then transplant them into the garden once all danger of frost has passed and the soil has warmed up. In regions with mild winters or long growing seasons, seeds can be directly sown outdoors after the last frost date. Proper timing is very important, as Lemon Basil prefers warm conditions and won’t survive cold temperatures.

To start Lemon basil indoors, sow seeds 1/4 inch deep in seed trays filled with light, well-draining seed-starting mix. Maintain soil temperatures between 70 to 85°F for germination. Set out seedlings at any size, when warm conditions have arrived. Space them 8 to 12 inches apart in the garden to ensure adequate airflow. Harden off seedlings to prevent transplant shock. Keep soil consistently moist during germination and early growth.

Water regularly to keep the soil evenly moist but not soggy, as overwatering can lead to root rot. Pinch off the top leaves frequently to prevent the plant from flowering (bolting), which can reduce flavor and leaf production. Pests like aphids and whiteflies can be managed with organic pest control methods, such as neem oil or insecticidal soap. Companion planting with tomatoes or peppers can also deter pests naturally.

• 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.
