Perfect for ANY Garden:

  • Basil is perfect for urban gardening, window boxes, garden containers, and areas of little space. It is also great in traditional gardens, raised garden beds, and even indoors.

Harvested All Summer:

  • Basil can be harvested all summer. The more you harvest basil the more it will grow.

THESE Could Harm Your Basil

Disease:

  • Basil is one of the most disease-prone herbs. Expect blight, fungus, and rot to affect your plant in the later summer months.

Frost:

  • If the weather drops below 35 degrees Fahrenheit expect your basil to not grow, become stunted, and die. This means you should grow your herb well after the last frost and harvest before the first frost of the fall.
