One of the first steps you take when you are estimating your gardening schedule is find your USDA Zone info. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

In Boone you can estimate when it's the best time to plant lavender by looking at the USDA zone info.

Planting Calendar for Lavender

Since lavender do well in moderate cold you can plant them a little bit earlier in the year than other plants that might not handle the cold.

The earliest that you can plant lavender in Boone is February. However, you really should wait until March if you don't want to take any chances.

The last month that you can plant lavender and expect a good harvest is probably September. You probably don't want to wait any later than that or else your lavender may not have a chance to grow to maturity. Starting your lavender indoors is a great way to get them started a few weeks earlier.
