Before planting it is a good idea to find your USDA Zone info to estimate your garden schedule. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

A way of figuring out when it's the best time to plant snapdragons is to use the USDA zone info for Zone 6a.

The last month that you can plant snapdragons and expect a good harvest is probably September. If you wait any later than that and your snapdragons may not have a chance to fully mature. Starting your snapdragons indoors is a great way to get them started a couple of weeks earlier.
