When can I plant Cucumbers in Zone 1b

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

A common way of making a decision about when it's the best time to plant cucumbers is to examine the USDA zone info for Zone 1b.
