If you are like most gardeners, you are probably wondering why your cucumbers are turning out white. This is not an uncommon problem, but there are several things that can cause it. In this blog post, we will discuss the most common causes of white cucumbers and how to fix them. Stay tuned for more information!
The finer points of growing cucumbers
Many people who are new to growing cucumbers may encounter a problem when the fruits begin to turn white. Do not immediately throw away such a fruit, because it is allowed to eat, but the problem is certainly worth investigating. The causes of white cucumbers can be various factors, which we will talk about in our blog article and tell you how to fix it.
Reasons why cucumbers turn white
Check the seeds of planted cucumbers
It may seem absurd, but sometimes it happens that when planting, a gardener may forget what variety of cucumbers he planted. After all, there are very popular and sought-after types of white fruit in the sale of cucumber seeds, which explains the color of the cucumbers as they mature. Some types of cucumbers begin to turn white toward maturity, so they confuse people and make them think the fruit is gone.
It is also important to buy seeds only from proven horticultural stores. If you buy seeds from hand, some producers may be unscrupulous and instead of a certain type of seed, give you others. Or the producer could save money and cross-pollinate cucumbers, which in the end and will give an unclear and unknown variety, giving in the end the white color of the fruit.
Cucumber powdery mildew is one of the most common diseases of cucumbers. It is a type of fungus that thrives in warm, humid conditions. The powdery mildew fungus affects the leaves and stems of cucumbers, causing them to turn white. This disease can spread quickly, so it’s important to take action as soon as you notice the signs.
If it is infected, the fruit feels like it is covered in flour. The plaque can be dense or barely visible, where it all depends on the degree of infestation and the development of the fungus. If you are sure that the cucumbers are infested with powdery mildew, you need to dilute one tablespoon of baking soda with one gallon of water and spray the cucumbers twice a week.
From now on, make sure that the cucumbers are in good growing conditions. This is ventilation and moderate watering.
Another name for the disease is cotton rot. It is a fungus that quickly affects cucumbers. In such a case, a dense white foam resembling cotton forms on the fruits of cucumbers. This problem usually occurs on one side or end of the fruit. It occurs because of excessive moisture and abundant watering. Also due to lack of air. Therefore, it is important to plant cucumbers properly, so that they are provided with quality ventilation. To get rid of the fungus will help treat the fruit with a chemical fungicide, which can be purchased at a gardening store.
Overwatering cucumbers can lead not only to fungal diseases, but also to a loss of important elements. If you water cucumbers too much, they will stop getting enough phosphorus from the soil, so they will gradually lose their green color and become white. Solve the problem by checking the soil for phosphorus content, if it appears to be in the soil is not enough, then it is time to reduce the watering of cucumbers by half, and the soil itself is abundantly fertilized with phosphorus.
The lack of light
Lack of sunlight is the main reason why cucumbers are white. Cucumbers grow low to the ground and do not get much sunlight. This can cause the cucumber to have a pale color. If your vegetable garden is in shade, get your cucumbers used to growing on a trellis. This way they can get enough light and won’t turn white.
If you can’t put a trellis in the vegetable garden, then trim the foliage from the trees surrounding the vegetable garden to let more sunlight into the cucumbers.
Shock during a transplant
Transplanting can cause your cucumbers to turn white. This can happen if you planted your cucumber seedlings too deep or if you damaged the roots during transplanting. Also, if you planted cucumber seeds indoors and then transplanted into soil outside, its leaves can begin to turn white. This process will pass with time and the cucumber will adjust. You need to observe the planting for 2 weeks. If the white color doesn’t go away, then there is another problem.
Root rot occurs due to two causes: improper and too abundant watering in the first most popular case, and in the second – it is damage to the roots when replanting the cucumber.
In the first case, you need to be careful and strict about watering cucumbers, checking the weather forecast, taking into account the type of soil and more. In the second case, you need to be very careful to transplant cucumbers, or seedlings from the room, so as not to damage the roots. If the roots are damaged, the fruit can no longer be helped.
Can I eat white cucumbers?
Yes, you can eat white cucumbers! In fact, they are just as nutritious as green cucumbers. The only difference is that white cucumbers have a milder flavor and delicate skin. So if you’re looking for a cucumber that’s easy to bite and has a delicate flavor, white cucumbers are good for you. But in some cases, these cucumbers can be bland and tasteless, depending on your luck. It is strictly forbidden to eat white cucumbers if they are affected by fungal diseases. In this case, you can easily be poisoned.
