Cucumbers are generally ready to pick about 50 to 70 days after planting, or 8 to 10 days after the first female flowers open. The best time to harvest is when the cucumbers are firm, shiny, and have reached the expected size for their specific variety. Here are general size guidelines for different types:
- Pickling cucumbers: about 2 to 4 inches long
- Gherkins: about 2 inches long
- Slicing cucumbers: 6 to 9 inches long with a dark green color
- Burpless varieties: 6 to 8 inches long
- Armenian cucumbers (a type of prickly cucumber): 8 to 10 inches long
Key signs to pick cucumbers include:
- Firm texture (not soft or mushy)
- Uniform medium to dark green color (avoid yellowing which means overripe)
- Even shape without bulges or odd formations
It's best to harvest cucumbers in the morning when the vines are cool, and daily checking is necessary because cucumbers can quickly go from ripe to overripe. Overripe cucumbers left on the vine too long can develop a bitter flavor. If you notice cucumber leaves turning yellow, it usually means the cucumbers are past their prime and should be picked soon. In summary, monitor the size and color according to the variety you grow, harvest when firm and green before yellowing appears, and do so preferably in the morning for the best flavor and texture.
