Caring For Your Cucumber
When Is The Right Time To Fertilize My Cucumber?
You can start fertilizing your cucumber when you see the blossoms first appearing in your plant. When you initially plant the cucumber, you would need to water it adequately. The appearance of blossoms gives you the indication that your plant needs proper fertilization to boost growth.
How Often Should The Cucumber Be Fertilized?
Your cucumber plant’s feeding pattern would depend on the growth stage and the fertilizer you have chosen. There are clear instructions given on the package of the fertilizer, which should be strictly followed. Generally, it is advisable to fertilize your plants every three months.
Keeping a well-maintained gap between each fertilization period gives the soil the chance to grab the nutrients and work its way into the roots. If you give fertilizer to your plants very frequently, then it could do more harm than good. Extra feeding will increase the nutrient quantity in the soil.
Too much of nutrients could suffocate the roots, thereby killing the plant slowly. You should also ensure that your plant receives water abundantly so that the nutrients can mix properly and reach the roots.
Which Fertilizer Will Be Best For My Cucumber?
The nutrient requirement for the proper growth of cucumber is high, but the nutrient kind will vary. Nitrogen is required in a very low amount, where Potassium and phosphorous are needed in high amounts by the plant. When using commercial fertilizers, you need to check the NPK ratio of the fertilizer you are buying.
The NPK ratio is shown in the form of 4-4-4 or 10-10-10, with the first number showing the percentage of Nitrogen, the second number of Phosphorus, and the third number of Potassium. This helps you understand which nutrient content is found more in the fertilizer. Try to choose a fertilizer that has a higher content of P and K than N.
The kind of soil that your cucumber is growing on will also decide which fertilizer would be best for you. Some soil lacks Nitrogen, and for that, you need a fertilizer with slightly higher Nitrogen content. However, the Nitrogen percentage should not be too high as it can damage the plant.
If you also want to use home-made fertilizer, then the best would be well-aged compost. This is a very natural form of fertilizer that would do wonders for your plant.
Is Well-Aged Compost Good for Cucumber?
Well-aged compost is one of the best kinds of fertilizer that you can use for cucumber. This compost contains a Nitrogen content of just 2%, and the release for this is very slow. It takes years for the compost to release the Nitrogen into the soil. One very interesting thing about well-aged compost is that it does not enhance its vegetative growth by reducing fruit growth.
Well-aged compost ensures proper nutrient reserves that can mix with the soil in the long term. You can apply this compost every year or even before you plant the seeds in the soil. This reduces the nutrient buildup in the soil and supplies only what is needed for your plant’s proper growth.
The compost will also provide your soil with Potassium, micronutrients, and phosphorous. It also keeps weeds away from your plant, leading to a proper intake of nutrients from the soil.
Can Cucumbers Be Grown In Containers?
Cucumbers can be grown in containers depending on the variety of the plant. Bush cucumbers are the ones that are generally grown in containers. When choosing to grow your cucumber plant in a container, you should opt for a bigger size. This would allow your plant to breathe and spread out.
If the container is too small, then the plant will not grow to its right size. This may also lead to damage and finally death of the plant. You also need to see that the container you choose can hold a good amount of potting soil. This helps in retaining water for a long time, which will be beneficial for your plant.
Cucumbers need moisture persistently; that is why a too small amount of soil will hold less water, drying out the plant. You also need to ensure that the container you are choosing can be moved around. Cucumber plants need about eight hours of sunlight.
If you do not want to keep them out at all times, you need a portable container. This makes it easy to move your container to direct sunlight each day and move it inside to the designated area once the sunsets. Check the soil’s temperature and the kind of fertilizer that is good for your container grown cucumber.

Frequently Asked Questions
1. Can I Use Eggshells for My Cucumber?
Yes, eggshells can be used for your cucumber plant. Eggshells are a good source of calcium, which is essential for the healthy growth of your plant. Made from calcium carbonate, using eggshells will provide your plant with the much-needed minerals. However, a whole eggshell would not do the job.
You need to grind the eggshells in your grinder and make them into a fine powder. Apply this powder to the soil, and slowly this will be released into the soil. It takes a lot of time for the eggshells to get absorbed by the soil and into the roots. Tilling helps the eggshells to reach the roots properly.
A great thing about eggshells is that they keep slugs away. Slugs are very much attracted to cucumbers and eat them away if proper care is not taken. Eggshells will not only supply necessary minerals to your plants but also keep them safe from slugs. When applied alongside fertilizers, you can see the change that your plant would go through.
2. Should The Leaves Be Removed From The Cucumber Plant?
Removing the healthy part of a plant is ever recommended since that can affect the growth. Some people state that removing the leaves from cucumber plants can lead to a reduction in disease. Furthermore, it also makes it easy for the pollinators to find flowers. Removing leaves is also said to increase the airflow in the plant.
Despite these benefits, it is said not to remove more than one leaf from your cucumber plant at one time. Moreover, try not to pluck any healthy leaves from your cucumber plant. There are small leaves known as suckers that need pruning. Even these should not be done in extreme numbers. Suckers are important for the plant as they support the growth of female flowers.
Frequent pruning is discouraged as it delays harvest and also reduces the production of your plants. That is why experts advise not to remove leaves from your cucumber plant unless absolutely necessary.
3. Why Does My Cucumber Plant Have No Fruits But Many Flowers?
There are many reasons why your cucumber may have many flowers but no fruits. One of the reasons could be the absence of any female flowers. Cucumber plants are said to be monoecious. That means that you will find male as well as female flowers together on the plant. Male flowers do produce pollen; however, they do not produce fruits.
Female flowers are the ones that produce small fruits. They tend to come in singles, while male flowers are found in clusters. If your plant has only male flowers, it could be one main reason for the lack of fruits. This is not something you need to stress about since male flowers tend to appear earlier than female flowers.
Only after the male flowers have blossomed will you see female flowers growing on your plant. Some other reasons for the lack of fruit could be a reduction in pollination or unfavorable temperature that has stopped female flowers and fruits’ growth. Additionally, if your soil has excessive nitrogen content, flowers’ growth, especially female flowers, could reduce.
4. Should The Flowers Be Picked Off The Cucumber Plant?
Picking off male flowers from your cucumber plants is necessary once every week since they can turn your cucumbers bitter. Even if you are planting cucumber for the first time, you can easily differentiate between female and male flowers. Male flowers just have stalks, and female flowers have tiny fruits growing behind their petals.
Male flowers generally stay for a day and then fall off. However, every week you should form a schedule and pluck the male flowers you see on your plant. If the male flowers pollinate your cucumber’s female flowers, then the fruits grown will have a bitter and nasty taste. This is due to Cucurbitacin, which is a bitter element in the seeds.
This process needs to be only done for indoor cucumbers. For outdoor cucumbers, male flowers are not required to be plucked. If you have an outdoor cucumber plant, then the bitter taste could be because of many other reasons and not because of the male flowers.
5. What Happens When I Overwater My Cucumber Plant?
Overwatering any plant is not a good thing. Though many plants require abundant water, you must know when to stop watering them. Cucumber plants that are overwatered will have yellow leaves. This is the most common indication of having overwatered cucumber plants along with the rotting of roots.
When your cucumber plant roots stay submerged in water, they slowly get damaged and absorb the nutrients that contribute to their growth. This slowly damaged every part of your plant and could also kill them if not taken care of. You may see that the leaves of your cucumber plant have turned yellow and are falling off.
When you see this, you need to immediately drain the excess water that has been collected in the base of the plant. Check for a proper drainage system around the roots so that the water can be taken out. If the roots are over-exposed to standing water, then they could rot very quickly.
6. How High Can My Cucumber Climb?
The height of your cucumber plant will depend on the variety of the plant. Some varieties grow very high, about 7 feet, while others may not even be one foot in height. If you are growing the cucumber in any trellis, then knowing the height of your cucumber variety will help you install the trellis according to the same height.
While there are height variations of cucumber plants, they will only grow until the trellis’ height or any other support. In case they do not receive the needed support, they will crawl in the ground and spread on your lawn. Depending on the availability of space, you can opt for two different kinds of cucumbers.
Vine cucumbers can grow between the heights of 3 to 7 feet, depending on what variety you are choosing. On the other hand, bush cucumbers grow only about 2 feet and are best for growing containers.
Cucumbers are a tasty and healthy fruit that also has many other uses. Growing cucumbers in your house can be very beneficial. However, to grow any plant, you need to make sure that they are receiving proper care. Plants are like babies; they require tenderness and care for them to grow strong.
Using proper fertilization is one of the key components of plant growth. Unfertilized plants would not be able to grow the way you want. However, you cannot just choose the first fertilizer that you see. While choosing a fertilizer, you need to see if they are suitable for your plant and deliver the right nutrients.
The fertilizers mentioned in this guide are some of the best options for cucumber plants. There are also many other options in the market that you could opt for. No matter which fertilizer you choose, follow the application instructions properly to not overuse or underuse them.
