One of the best tools that you have as gardeners to help us figure out your gardening schedule is the USDA zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

A way of determining when it's a good idea to plant bacopa is to consult the USDA zone info for Kelso.

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 are one of those plants that can tolerate a tiny bit of cold weather which means that you can get them planted just a bit earlier than plants that are more sensitive to the cold.

The earliest that you can plant bacopa in Kelso 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. You probably don't want to wait any later than that or else your bacopa may not have a chance to really do well. If you are starting your bacopa indoors then you might be able to get away with starting them a little bit earlier.

Last Frost Date

The average date of last frost is March 15 in Kelso. In the coldest months of winter you should expect an average low temperature of 15°F.

Always keep in mind that the actual date of last frost is just an average because it is based on the USDA zone info for Kelso and it can change quite a bit from year to year. Half of the time in Kelso last frost occurs after March 15 so just be sure to be ready to cover your bacopa if you have one of those late frosts.
