One of the first steps you take when you are figuring out 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.

The USDA zone info for Zone 1a can be read to estimate when it's a good idea to plant bacopa.

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.

You can plant bacopa just a tiny bit earlier in the year because they are one of those plants that can tolerate a tiny bit of cold weather.

The earliest that you can plant bacopa in Zone 1a is June. However, you really should wait until July if you don't want to take any chances.

The last month that you can plant bacopa and expect a good harvest is probably July. You probably don't want to wait any later than that or else your bacopa may not have a chance to grow to maturity. You can get started a little bit earlier by starting your bacopa indoors.

Last Frost Date

The average date of last frost is June 15 in Zone 1a. It might get as low as -60°F during the coldest months of winter.

Remember that the actual date of last frost is an average because it is based on the USDA zone info for Zone 1a and it is different every year. Half of the time in Zone 1a it frosts late in the year after June 15 so make sure that you are ready to cover your bacopa in the event of a surprise late frost.
