One of the first steps you take when you are estimating your gardening schedule is find your USDA Zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

In Honolulu you can determine when to plant gherkins by using the USDA zone info.

Planting Calendar for Gherkins

Frost tolerance for gherkins:	Not tolerant of frost.
When to plant:	After the last frost when the weather gets warmer.

It's not a good idea to plant gherkins until after the last frost because they are not cold tolerant.

The earliest that you can plant gherkins in Honolulu is January. However, you really should wait until February if you don't want to take any chances.

The last month that you can plant gherkins and expect a good harvest is probably November. If you wait any later than that and your gherkins may not have a chance to fully mature. If you are starting your gherkins indoors then you might be able to get away with starting them a few weeks earlier.
