Pick off male cucumber flowers once a week to avoid your cucumbers turning bitter. Most greenhouse cucumber plants produce both male and female flowers – it’s easy to tell the difference as male flowers have simple stalks while female flowers have miniature fruits forming behind the petals.
To avoid a bitter tasting Cucumber, pick off male flowers once a week
If you allow the male flowers to develop and pollinate the female flowers, the fruits that develop will leave you with a nasty aftertaste as the seeds contain a bitter compound called cucurbitacin. So make it a regular job to remove male flowers and keep your fruits seed-free and sweet.
You can avoid the job altogether by choosing modern F1 varieties bred to produce only female flowers, like ‘Carmen’ or ‘Tiffany’. They may cost a little more but they’ll save you a lot of trouble. Avoid mixing them with other cucumber varieties though, or they’ll cross-pollinate and undo your hard work.
Outdoor Cucumbers are fine!
You don’t need to pick off male flowers from outdoor cucumbers, which need to cross-pollinate in order to develop fruit. If these taste bitter, it’s probably down to stress: sudden changes in temperature, erratic watering and lack of feed all turn outdoor cucumbers bitter and occasionally affect indoor ones, too, so keep conditions as even as possible throughout the season.

At higher densities, plants compete for water, nutrients, and sunlight, and the resulting stress can lead to a higher proportion of male flowers. Optimum populations for hand-picked slicing cucumbers are in the range of 24,000 to 26,000 plants per acre.
A: Pinch off the flowers if you want more stem and leaf growth – especially if the plant is young. You can remove flowers on the bottom so the plant will focus more on the top cucumbers (this will also keep cucumbers off the ground).
It's best to cut these off, and allow the plant to focus it's energy on growing a strong root system, with plenty of foliage, and growing to a big enough size to be productive. Allowing your cucumber plants to produce flowers and fruit now can stunt growth, as the plant won't be strong enough.
Both should be left on outdoor varieties, but pinch off the male flowers when they appear on indoor varieties to prevent the fruit from becoming bitter. The flowers are easy to tell apart - the female flower has a swelling beneath it that will become a cucumber.
If you like the older varieties of cucumber, that's great, just remember that even one or two male flowers can turn the crop bitter, so be vigilant. Growing an all-female variety, like cucumber F1 Bella, helps to guard against this problem. The other cause of bitter cucumbers is plant stress.

Cucumber varieties are either monoecious or gynoecious in their flowering patterns. Gynoecious varieties produce only female flowers and have a more concentrated period of fruit production. There are also parthenocarpic varieties that do not need to be pollinated to produce fruit.
If after a month or so plants are still producing only male flowers or very few flowers generally, despite plants looking healthy, then the culprit is likely an imbalance in nutrients. Excess nitrogen will encourage lots of leafy growth at the expense of flowers.
Additionally, cucumber plants require regular fertilization with a balanced nutrient solution, including nitrogen, phosphorus, and potassium, as well as micronutrients such as calcium, magnesium, and iron. Proper plant spacing and trellising are essential for maximizing yields and preventing overcrowding and disease.
The blossoms stay open for about 4 hours and if they do not get pollinated in the time frame that they are open they will not produce a fruit or it will be misshapen do to lack of pollination.
However, if you see the female flowers on your cucumber plants, but they are not "setting" fruit, then the problem may be that you do not have pollinators. In the past several years we have had various problems affecting the honey bee populations. However, bumblebees are good pollinators for these plants.
Depending on who you ask, a healthy cucumber plant can be expected to produce 10 large cukes or 15 small ones within a harvest period of about three weeks.
You see, typical cucumber plants, especially heirloom varieties, contain both male and female flowers, but it's only the females that produce the actual fruit. That's not to say that the males don't have a purpose. They contain pollen that needs to be transferred over to the female flowers.
