Seed Sowing & Growing Notes
Start seed indoors in trays 6 weeks before last frost; transplant out after all danger of frost has passed. Basil is very sensitive to cold; wait until the weather has warmed to transplant out.
Harvesting/Vase Life
Harvest when stems begin to toughen, or as soon as flowers begin to form. Be sure to cut during the coolest part of the day to minimize wilting. Immediately after harvest, dip the bottom few inches of the stems in boiling water for 7 to 10 seconds, or use Quick Dip, then place into cool water. Expect a vase life of 7 to 10 days.
