Before planting it is a good idea to find your USDA Zone info to estimate your garden schedule. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

In Ottawa you can figure out when to plant bacopa by referring to the USDA zone info.

Planting Calendar for Bacopa

Frost tolerance for bacopa:	Tolerant of a very small amount of frost.
When to plant:	Up to 3 weeks before last frost.

Bacopa tend to make it in a tiny bit of cold which means that you can plant them just a tiny bit earlier in the year than other frost tender plants.

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

The last month that you can plant bacopa and expect a good harvest is probably August. If you wait any later than that and your bacopa may not have a chance to really do well. Starting your bacopa indoors is a great way to get them started a little bit earlier.

Last Frost Date
