The finest indoor plant fertilizers should have a mineral balance to promote strong roots, lush foliage, and attractive blooms.

Choosing the right houseplant fertilizer might be difficult. Although there are some all-purpose liquid plant foods available that are found to produce amazing results for indoor plants. As a result, you must select one that offers the proper mix of micro- and macronutrients required by particular home plants.

This article offers a brief overview of houseplant fertilizers and will help you decide which one is ideal for your potted plants. But before we get into this it's necessary to know why indoor plant requires fertilizing.

Why Do Indoor Plants Require Fertilizer?

Fertilizing houseplants is necessary to supply nutrients for optimum development. Regular feeding fills the potting soil with nutrients required by indoor plants. Indoor plants, unlike outdoor plants, require fertilization because they lack organic materials. Applying fertilizer regularly ensures that your houseplants remain healthy.

Fertilizer is not the same as plant nourishment, according to science. The majority of plants produce their nourishment by absorbing water and carbon dioxide. Plants, on the other hand, require additional nutrients present in the soil, such as nitrogen, phosphorous, and potassium. Fertilizers supply these nutrients to plants.

Plants obtain their nourishment via photosynthesis, which occurs when plants receive energy from light. Plants take carbon dioxide from the atmosphere as well as water from the soil. These react to form sugars, which the plant consumes. Plants, therefore, nourish themselves by producing their food.

Plants, of all, require more than just food to survive. Fertilizing plants on a regular basis ensures that they receive key macronutrients like nitrogen, phosphorus, and potassium, which are sometimes missing in potting soil. Even though plant food is not technically a fertilizer, most people use the terms interchangeably.
