This year for the first time, the cucumbers from my garden are bitter. What is causing this.

[The Independent Gardener]

Probably caused by uneven water availability though unbalanced soil nutrients could also have caused the problem. A high level of humus will help keep water in the soil where the roots can find it. Add compost to your soil and/or mulch with an organic material like grass clippings.
