Basil Seeds,
Purple Ball

Purple Ball basil is a warm-season herb that should be planted only after the danger of frost has passed. Typically, this means late spring to early summer, depending on your local climate. Basil grows best in temperatures between 70-85 F. To identify the best planting time, consult your local area's frost dates.

Start Purple Ball basil seeds indoors 4 to 6 weeks before the last frost date in your area. Sow seeds 1/4 inch deep in a well-draining seed-starting mix and keep the soil evenly moist. Germination takes about 6 to 10 days. When transplanting, space plants 6 to 8 inches apart in nutrient-rich, well-draining soil. If sowing directly outdoors, wait until the soil temperature has warmed to at least 60°F. Thin seedlings after germination to ensure proper spacing and airflow.

This variety requires consistent watering, but be careful to avoid overwatering, as it dislikes soggy soil. Water at the base of the plant to prevent fungal issues and keep the leaves dry. Adding mulch around the plant helps retain moisture and prevent weeds. To maintain its compact, spherical shape, prune or pinch back stems regularly. For the best flavor and freshness, harvest leaves mid-morning, after the dew has dried but before the heat of the day.

• 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.
