One of the best tools that you have as gardeners to help us determine your gardening schedule is the 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 first opportunity to plant gherkins in Zone 1a should be figured out by referring to the USDA zone info.

Planting Calendar for Gherkins

Frost tolerance for gherkins:	Not tolerant of frost.
When to plant:	After all chance of frost has passed.

Gherkins do not do well in cold weather which means that you have to wait until it warms up after the last frost when the weather gets warmer before you can plant them.

The earliest that you can plant gherkins 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 gherkins and expect a good harvest is probably July. Any later than that and your gherkins may not have a chance to really do well. If you are starting your gherkins indoors then you might be able to get away with starting them a couple of weeks earlier.

Last Frost Date

The average date of last frost is June 15 in Zone 1a. In the coldest months of winter you should expect an average low temperature of -60°F.

Always keep in mind that USDA zone info for Zone 1a is just an average and the actual date of last frost is different every year. Half of the time in Zone 1a last frost occurs after June 15 so make sure that you are ready to cover your gherkins if you have a late frost.
