It's probably a bad idea to plant gherkins until after the last frost has passed because they do not do well in cold weather.

The earliest that you can plant gherkins in Highland 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 gherkins and expect a good harvest is probably September. You probably don't want to wait any later than that or else your gherkins may not have a chance to grow to maturity. You can get started a few weeks earlier by starting your gherkins indoors.
