What to consider when buying the Best fertilizer for tomatoes and cucumbers

a) Healthy Nutrients

Tomatoes and fertilizers require fertilizers with less Nitrogen and more phosphorous or Potassium. For instance, the NPK ratio of 6-8-10 and 4-4-4 is suitable to grow tomatoes and cucumbers since nitrogen content doesn’t surpass the other two nutrients.

You should avoid fertilizers that have higher nitrogen content since it will increase the production of vines and foliage but could hinder the crop from producing tomatoes or cucumbers.

b) Organic or Synthetic

There are two types of fertilizers; organic or synthetic, and you should know the best one to go with. Organic fertilizers have nutrients that are sourced from nature like compost poultry manure, bone meal, and worm castings. Besides, no chemicals are used while creating the product.

Synthetic fertilizers contain non-organic ingredients and may still boost harvests and produce healthy plants. Besides, it’s less expensive than other organic fertilizers.

c) Types of Fertilizer (Granular, Liquid, Water soluble)

You should also consider the type of fertilizer to use. It can either be granular, liquid, or water-soluble. The granular fertilizers resemble tiny pellets and release the nutrients gradually to keep plants healthy for some weeks. They are usually mixed in the soil, where they dissolve slowly. The liquids fertilizers are available in a highly concentrated form where you mix with water before using. It’s then sprayed on the plants and rapidly absorbed by the plants. They also wash out of the soil very fast, leading to frequent feedings.

Conversely, water-soluble fertilizers come in either fine granule or powdered form and are made to dissolve in water quickly. You can stir into the water can or use a garden hose to spray across your plants.

d) Right combination of elements (NPK ratio)

You should also consider the combination of elements available in your fertilizer, which is the NPK ratio. The ratio is made of Nitrogen, Phosphorous, and Potassium. Nitrogen helps in foliage growth, phosphorous with flower, root, and fruit production, and Potassium is responsible for building strong stems and the overall health of your tomatoes and cucumbers. For instance, the ratio 4-6-4 implies that there is a 4% of N, 6% of P, and 4% of K.

Even though basic nutrients like Nitrogen may still be available in your soil, they still might not be in the right amount necessary to grow the tomatoes and cucumbers. So, ensure you conduct a soil test to know the PH of your soil.
