What must a fertilizer contain?

To properly feed the plants and help them develop, a fertilizer should contain Nitrogen, Phosphorus and Potassium. These substances promote foliage, root and flower (or fruit) formation, respectively. The catch is that if you want beautiful flowers, the solution should contain more Phosphorus. Additionally, the bottle won’t only contain these 3 components, but the highest concentration is of 10% of each when compared to the whole quantity.

Why are there more types?

Visiting the garden center, you’ll notice several types of plant food: foliar, organic liquid, solid, and others. Each of these types address a different need and preference. They also have a different concentration, when it comes to the substances they provide to the plants. Some of them are specially formulated for specific types of plants, for not all of them need the same amount of substances.

Fertilizers are usually applied at the root of the plant, however sometimes you might need to use a foliar fertilizer. This one gets sprayed on the plants’ leaves, but it’s not always enough and not all plants like it. The foliar flower fertilizer quickly addresses a potassium deficiency. Chemical fertilizers are good for ornamental plants and bushes.

Based on how they were obtained, there are chemical and organic fertilizers as well. You might want to choose a natural product if you need to use it on edible plants. Even on non-edible plants, the organic one might be a better choice because they have more benefits than any other type of plant food. For instance, there’s no risk of burning the plant, and beneficial insects will thrive as well.

A major difference between the organic and the chemical fertilizers is the release time. The former is a slow nutrient releaser while the later releases the nutrients faster. The organic one might be best used outdoors though indoor application is also possible.

Are there any risks?

Just like with any other product, there are risks involved with all fertilizers. The organic ones might smell appetizing to your pets, despite it smelling bad to you. The chemical fertilizers when applied in a high quantity or concentration can burn the plant instead.

Is there an absolute best such product?

Most likely the best product is the one created specifically for the type of plants you have. Buying specific blooming fertilizers for each flower or shrubs could be too expensive, and if money is not something you can spare, an all purpose one will do the job just fine. An organic one might be a good option of you are forgetful as you don’t need to use it as often as the chemical one.
