Pesto Besto is the most amazing seed basil you've ever seen. This is truly a game-changing plant-it is the most downy mildew resistant seed grown Italian sweet basil. This large, vigorous plant produces a high yield of usable, deliciously aromatic leaves. The more you harvest, the better it grows. Harvest sprays of leaves by cutting stems just above 2 new sprouting lateral branches to get lush regrowth. For best flavor and leaf production, harvest and or pinch regularly to promote fresh tender growth. Sow seeds indoors 1/2 in. D 6-weeks before your local frost-free date. Seeds should germinate in 5-days to 10-days at 70°F. Keep soil moist. Transplant outdoors when night temperatures are above 65°F.
