What Nutrients Do Cucumbers Need?
Cucumbers are a refreshing and healthy addition to any diet, but they do have specific dietary needs in order to thrive. Cucumbers are especially high in water content, so they need plenty of moisture to stay hydrated. In terms of nutrients, cucumbers need nitrogen, potassium, and phosphorus for proper growth. Nitrogen is essential for leaf and stem growth, potassium helps with fruit production, and phosphorus aids in root development.
Without these key nutrients, cucumbers will not grow properly and will likely produce small, misshapen fruits. Luckily, cucumbers are relatively easy to care for, and as long as they are given the proper attention and nutrients, they will continue to grow healthy and delicious fruits year after year. So, let’s see how to make that happen and how to properly choose a fertilizer for cucumbers!
The Best Fertilizer for Cucumbers
When choosing a fertilizer for cucumbers, it is important to select one that is high in phosphorus and potassium. Additionally, cucumbers prefer a slightly acidic soil, so a fertilizer with a slightly lower pH can be beneficial. The best cucumber fertilizers are 2-5-3 or 5-10-10, preferably high in minerals like zinc, magnesium or calcium.
Manure is an excellent choice to fertilize cucumber plants, but it is important to age it before using it in the garden. Fresh manure can actually damage plant roots and should be avoided. Compost is another organic fertilizer that can provide cucumbers with the nutrients they need while also helping to improve soil structure. For best results, mix compost into the soil before planting and apply additional compost around the base of plants every few weeks.
What’s the Best NPK Ratio for Cucumbers?
There are three primary nutrients that all plants need: nitrogen (N), phosphorus (P), and potassium (K). These are typically expressed as an NPK ratio on fertilizer labels. For cucumbers, the ideal NPK ratio is 5-10-10. This means that the fertilizer is 5% nitrogen, 10% phosphorus, and 10% potassium. This combination of nutrients will encourage strong growth and bountiful fruit production. You should avoid vegetable fertilizers with a high nitrogen ratio. Nitrogen promotes leaf growth, and your cucumber plant will end up with more leaves than fruit.
Liquid vs. Granular Cucumber Fertilizers
Is 10-10-10 Fertilizer Good to Grow Cucumbers?
Is 10-10-10 fertilizer good for cucumbers? It’s not a bad one. For cucumbers, a slightly higher percentage of potassium is ideal. This will help your cucumbers to produce more fruit, resulting in a healthier plant. If you are using a 10-10-10 fertilizer, simply add a little extra potassium (e.g., banana peels) to ensure that your cucumbers get the nutrients they need.

What Not to Fertilize Your Cucumber Plant With
It’s very popular to reuse kitchen scraps or other house waste as fertilizers in your garden. And while we believe it’s fantastic, we also know it’s not a very good idea while growing cucumbers. Some common household items, such as coffee grounds and eggshells, can actually harm cucumber plants. Coffee grounds can make the soil too acidic for cucumbers, and eggshells can raise the pH levels too high. Therefore, you should avoid both of these as fertilizers for cucumbers.
