One of the best tools that you have as gardeners to help us estimate 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.

It's a good idea to estimate when it's possible to plant painted tongues by checking out the USDA zone info for Humboldt.

Planting Calendar for Painted Tongues

Frost tolerance for painted tongues:	Not tolerant of frost.
When to plant:	After the last frost has passed.

It's probably a bad idea to plant painted tongues until after the last frost has passed because they are not cold tolerant.

The earliest that you can plant painted tongues in Humboldt is April. However, you really should wait until May if you don't want to take any chances.

The last month that you can plant painted tongues and expect a good harvest is probably August. Any later than that and your painted tongues may not have a chance to fully mature. If you are starting your painted tongues indoors then you might be able to get away with starting them a couple of weeks earlier.
