Why Are Your Cucumbers Round

Sometimes, you get to your garden or even at the grocery store and you see cucumbers with the unusual shape unlike the regular long thin ones.

This keeps you bothered because you’ve put in the work to grow your cucumber plants. You are also in the expectation of harvesting the type of cucumbers you want.

Let’s take a look at the reasons why cucumbers become round and deformed.

1.    Shortage Of Nutrients

A situation whereby there’s a shortage of nutrients available to cucumbers can be unpleasant to the plants. This can lead to the cucumber becoming round, stout, or short. And then you keep wondering and asking; why are my cucumbers round?

Cucumbers require lots of nutrients while growing. Before planting your cucumber, prepare the soil first by mixing compost and organic mulch in the soil. Do this a few weeks ahead of planting your cucumbers.

This will help in making the necessary nutrients available for the plants. However, you can first add little or no fertilizer to the soil if it’s fertile.  Once you notice a kind of abnormal growth or unusual changes about your cucumbers, like yellowing, get a fertilizer with an NPK of 5-5-10.

The plants need lots of phosphorus, potassium, and even more, nitrogen to be healthy again.

2.    Lack Of Water – Why Are My Cucumbers Round

Water in the right proportion is a necessity for cucumber plants for healthy growth. This means not watering your cucumber plants well can affect the growth of the cucumbers. This will result in a low harvest and deformed cucumbers.

Lack of water also leads to wilting of the plants in the sun due to dehydration. The solution is for you to water your plants once or twice every week, depending on the condition of the soil, if it’s wet or not.

Make sure you always check for soil dryness in order to know when it needs watering.

In fact, water the plants more if it is dry. This way, they get to have enough water for themselves but endeavor not to over-water the plants.

3.    The Environment Of The Plants

Another factor that can affect the looks of cucumbers is the environment where they are being planted. The soil for growing cucumbers must be well-draining. This helps to foster aeration, draining, and circulation of water in the soil.

Another factor to look out for is the temperature. If the temperature is below 50 degrees Fahrenheit and no form of light is available to the plants, their growth will be stunted. Furthermore, a high temperature around 95 degrees Fahrenheit and above is a no-no for these plants. This will reduce pollination, thereby resulting in lower plant yield, fruit size, shape, and quality.

4.    Poor Pollination – Why Are My Cucumbers Round

The main cause that can be attributed to underdeveloped or deformed cucumbers is pollination. The cucumbers won’t develop well or will have stunted growth if the flowers are not pollinated fully. On the same plant, there are cucumber cultivars with male and female flowers.

To transfer the pollen in them, they need pollinators. Hence, lack of pollinators like bees, hummingbirds, and butterflies, in the garden, may lead to ineffectiveness of the pollination process. In order to have more pollinators come to your cucumber garden, grow plants that have much pollen and nectar.

Furthermore, adopt more natural and eco-friendly methods of preventing the rampaging of pests in your garden. Like handpicking, shielding, and setting traps. Do this instead of the use of pesticides. This is because pesticides will kill the pollinating insects also.

Tips For Growing Better And Healthy Cucumbers

The following cucumber growing tips will help you in growing healthy cucumbers and harvesting quality cucumbers in your garden:

  • You can start your cucumbers with seeds indoors. Start them indoors three to four weeks ahead of the time you will be transplanting them in the ground.
  • Make sure the temperature of the soil is above 70 degrees Fahrenheit before you transplant the seedlings directly or plant the seeds in the ground.
  • If you’re planting the seeds directly, plant the seeds with the space of at least 36 inches apart.
  • Cucumber plants prefer loose well-draining soil. Hence, don’t choose a location with hard soil and small planting space.

  • The best soil to plant your cucumbers in is light and lovely sandy soil.
  • For clay soil, mix peat or compost in the soil for better soil.
  • Add more compost to the soil once you notice the appearance of new shoots. This helps the buds to grow more.
  • The habitat where your cucumber plants are grown must have good drainage. This will help the plants not to get rotten because the surrounding won’t get waterlogged. Hence, water gets to drain quickly.
