It's an age old conundrum for so many vegetables. After waiting all season for the fruits of your labor, they disappoint you with bitterness, sourness, toughness or some other uncorrectable malfeasance.
In the case of bitter cucumbers, the culprit it usually stress, and we've had enough of that this summer. Long periods of hot temperatures are the most common cause. There's not much you can do to control the heat, but keeping your cucumbers well watered will help offset the bitterness.
Another factor in bitter cucumbers is lean soil. Cucumbers are heavy feeders and a soil rich in organic matter will go a long way toward producing less stressed, better tasting cukes. If your soil is less than ideal, give your cucumbers a little food every 4-6 weeks.
And finally, look for varieties that are well suited to your area and site and that list non-bitterness as an attribute.
