3 How often to fertilize cucumbers in containers?
Regular fertilization is considered one of the good things you can do to ensure providing the right and needed amount of nutrients in the soil for your cucumbers in containers. First, you need to know that it depends on two things: 1) type of fertilizer (granular, liquid, or spikes). 2) Speed of melting and absorption (slow/fast release).
When you choose granular fertilizer with slow release, you are obliged to apply this fertilizer for your cucumbers in a container for just once or twice per year. This is due to the fact of the speed of fertilizing breaking and releasing.
The main job for this type is to release small doses of nutrients in balanced quantities during a long period of time. Applying it once or twice should be enough.
Meanwhile, when you choose liquid fertilizer with fast/quick release, you are obliged to apply this type frequently more than the slow type. Liquid fertilizer is particularized to be absorbed quickly in the soil because it is mixed up with water, also the quick release will allow your plant to benefit from the fertilizer in the fastest way possible.
Taking those two factors, liquid fertilizer with fast release should be applied once in a week along the growing season.
As you can see, there is no guide book for how often you should apply fertilizer on your cucumbers in containers. Equally important to this, choosing the right and best fertilizer for your plant will be condemned to certain facts.

4 How to Pick the Best Fertilizer for Cucumbers in containers.
Before we dig into which kind of fertilizer is best for your cucumbers in a container, there are some cornerstone facts about fertilizers and your plant altogether.
Cucumber is treated and grown as a vegetable despite the fact that it is a fruit. That means your cucumber will need nutrients just like what tomatoes need. This is considered a great thing because there are a lot of good fertilizers to choose from.
Moreover, cucumber plants prefer the fertilizers that contain phosphorus and potassium quantities more than nitrogen.
For further explanation, let’s learn what NPK refers to in every fertilizer package.
N: refer to nitrogen percentage.
P: refer to phosphorus percentage.
K: refer to potassium percentage.
Nitrogen is a necessary nutrient to any kind of plant, but when it comes to cucumber case, it has to be the least percentage between the other two. Let’s take an example just for references. A 3-4-4 NPK fertilizer is good for cucumbers, but a 7-3-5 NPK is not a good choice because nitrogen is higher than both phosphorus and potassium.
Furthermore, fertilizer price is another factor that enters the equation along with the kind of fertilizer ingredients whether it is organic or not, safe or dangerous for kids…
To choose the best fertilizer for cucumber in container you must consider:
- NPK references (must suit cucumber plant)
- Slow/fast release.
- Organic/ not organic (safe or dangerous).
- Price of fertilizer.

5 How to Add Fertilizer to Cucumbers in container:
Many times, I get frustrated with all these types of fertilizers and I ask myself: “how in the hell I’m going to l add this fertilizer to my cucumber plant!!” I sit in my place and I think, “This plant is like a baby, it is so annoying.”
Then, a spike of energy came to my head when I took a deep breath. I remembered my mother when she was planting when I was so young, she was always saying, “hey boy, any plant needs feeding just like you. You must feed it even before it see the first light, and you must feed it when it open her colored eyes”
When I remembered this, I also remembered the taste of the fruits she grew back then, wonderfully tasty and sweet.
In fact, any given plant including cucumber need to add them fertilizer in couple of crucial times which they are:
- Before planting or just after planting.
- When your plant starts blooming.
But how actually do you add fertilizer in cucumber plants? Well, it depends on the fertilizer type:
o If it is granular fertilizer: add the recommended amount in the package (usually 1 tablespoon) and mix it with the soil before or after just planting, then water it. Fertilize again when your cucumber produces flowers by the same amount.
o If it is water solution fertilizer: mix the recommended amount with water and add it to your cucumber plant, you must be aware that this kind is vulnerable against rain, so it is best to apply it during sunny days only. Apply it frequently once in a week because this type will be absorbed from the plant quickly, if you have chosen a slow time release, then a couple applications should be enough.
In brief, the cucumber fertilization process is an important process your plant needs in many growth stages. This is due to the fact that cucumbers need nutrients before planting, during the growing, and before producing fruits. The importance of this process can give you either great fruits when applied vs. unpleasant and small fruits when not applied.
In addition, the time of applying fertilizer to your cucumber must be done when you notice: small fruits, yellow leaves, and after transplanting.
Equally important, you should apply the fertilizer to your cucumber twice a year if it is slow release. And weekly applications if you are using fast release, this type must be applied on sunny days only.
Moreover, the best fertilizers for cucumbers in containers should hold these specifications: less nitrogen, organic, safe for kids, plenty of nutrients, and of course don’t consume a lot of money.
