How can I determine the cause of bitter cucumbers?
My cucumber harvests were bitter last year and I did not realize at the time that this may actually be caused by environmental factors as I had not grown that particular variety before and just put it down to a bad selection. I have purchased a different variety this year but I guess the principles are still the same. From what information I find on the internet, the bitterness is caused by uneven watering, changes in temperature or being too hot. How do I know for sure which one caused it and how do I protect my cucumber plants from temperature changes when they are outside? Is there a way to keep the plants cool if it becomes too hot?
