How to Feed Indoor Plants

Indoor plants are a fantastic way to bring nature into your home. They are not only aesthetically pleasing but also help purify the air. However, to keep your indoor plants healthy and thriving, it is necessary to provide them with proper nutrition. In this article, we will explore some tips on how to feed indoor plants.

Understanding the Nutritional Needs of Indoor Plants

Plants need food to grow and thrive, just like humans. However, indoor plants have different nutritional needs than outdoor plants. Indoor plants rely on their owners to provide them with the necessary nutrients, water, and sunlight. Understanding the nutritional needs of indoor plants is the first step in feeding them properly.


Plants require macronutrients, which are nutrients that they need in large quantities. The three primary macronutrients that indoor plants need are nitrogen (N), phosphorus (P), and potassium (K). Nitrogen helps plants grow stems and leaves, phosphorus aids in root development and flower production, and potassium helps with overall plant health and disease resistance.


In addition to macronutrients, plants also require micronutrients, which are nutrients that they need in smaller quantities. Micronutrients include magnesium, calcium, iron, and zinc, among others. These nutrients are essential for plant growth and development.

Choosing the Right Fertilizer

Choosing the right fertilizer is crucial to feeding your indoor plants properly. There are many different types of fertilizers available, and it can be overwhelming to choose the right one. The three primary types of fertilizers are liquid, granular, and organic.

A key takeaway from this text is that it is important to understand the nutritional needs of indoor plants and choose the right fertilizer to feed them properly. It is also crucial to follow the proper steps when feeding indoor plants and to monitor their growth to avoid overfeeding or underfeeding. Additionally, different plants have different nutritional needs, so it’s essential to research and understand the specific requirements of each plant.

Liquid Fertilizers

Liquid fertilizers are fast-acting and are absorbed by the plant quickly. They are easy to use and are often applied directly to the soil. However, liquid fertilizers can be expensive and need to be applied more frequently than other types of fertilizers.

Granular Fertilizers

Granular fertilizers are slow-release and provide a steady supply of nutrients to the plant over time. They are easy to apply and require less maintenance than liquid fertilizers. However, granular fertilizers can be more expensive than other types of fertilizers and can be difficult to apply evenly.

Organic Fertilizers

Organic fertilizers are made from natural materials and are often less expensive than other types of fertilizers. They provide a slow-release of nutrients to the plant and improve soil quality over time. However, organic fertilizers can be difficult to find and may not provide as many nutrients as other types of fertilizers.

How to Feed Your Indoor Plants

Feeding your indoor plants is a straightforward process, but it is essential to do it correctly. Overfeeding or underfeeding your plants can lead to poor growth and even death. Here are the steps to follow when feeding your indoor plants.

Step 1: Choose the Right Fertilizer

Choose a fertilizer that is appropriate for your indoor plant’s needs. Look for a fertilizer that is specifically designed for indoor plants and provides the necessary nutrients.

Step 2: Dilute the Fertilizer

Follow the instructions on the fertilizer packaging to dilute the fertilizer properly. Overdosing your plant with fertilizer can lead to nutrient burn and damage to the roots.

Step 3: Water Your Plant

Water your plant thoroughly before applying the fertilizer. This will help the plant absorb the fertilizer more effectively.

Step 4: Apply the Fertilizer

Apply the fertilizer according to the instructions on the packaging. Be careful not to get any fertilizer on the leaves or stems of the plant, as this can cause damage.

Step 5: Monitor Your Plant

Monitor your plant for signs of overfeeding or underfeeding. Yellowing leaves, stunted growth, and brown leaf tips are all signs that your plant may not be getting the right nutrients.

Tips for Feeding Indoor Plants

Feeding your indoor plants is not a one-size-fits-all process. Different plants have different nutritional needs, and it is essential to understand your plant’s specific requirements. Here are some tips for feeding your indoor plants:

Know Your Plant

Make sure to research your plant’s specific nutritional needs. Different plants require different types and amounts of nutrients, and it is essential to provide them with the right fertilizer.

Feed Your Plants Regularly

Indoor plants need to be fed regularly to stay healthy. Make sure to follow a regular feeding schedule and adjust it as needed based on your plant’s growth and development.

Use High-Quality Fertilizer

Using high-quality fertilizer will ensure that your plants receive the necessary nutrients. Look for fertilizers that are specifically designed for indoor plants and are high in macronutrients and micronutrients.

Don’t Overfeed Your Plants

Overfeeding your plants can lead to nutrient burn and damage to the roots. Make sure to follow the instructions on the fertilizer packaging and dilute the fertilizer properly.

Use Water-Soluble Fertilizer

Water-soluble fertilizers are easy to apply and are absorbed by the plant quickly. They are ideal for plants that require frequent feeding.

FAQs for feeding indoor plants

How often should I feed my indoor plants?

The frequency of feeding your indoor plants depends on various factors like the type of plant, the season, the pot size, and the soil type. Generally, indoor plants should be fed once every two to four weeks during the growing season (spring and summer), while once a month feeding is enough for dormant plants in fall and winter. Over-fertilizing can lead to burnt roots or foliage, so be sure to follow the instructions on the plant food package and avoid overdoing it.

What nutrients do indoor plants need?

Indoor plants require three primary macronutrients (nitrogen, phosphorus, and potassium) and secondary macronutrients (calcium, magnesium, and sulfur) to grow well. Nitrogen helps in the development of foliage, phosphorus helps in flower and fruit development, and potassium aids in overall growth and strength. Additionally, plants need micronutrients like iron, manganese, and zinc that are also present in commercial fertilizers.

Can I use compost to fertilize indoor plants?

Yes, compost is a great source of natural nutrients for indoor plants. You can make compost at home using kitchen scraps and other organic materials or buy it from a garden center. Compost releases nutrients slowly over time, providing a steady supply of essential nutrients. Mix one-third part of compost with two-thirds part of potting mix for best results.

Should I feed my indoor plants in winter?

Most indoor plants go dormant in winter, and their growth slows down. Therefore, feeding your plants in winter should be done sparingly, if at all. Too much fertilizer can lead to root rot or weaken the plant during dormancy. If you want to feed them, we recommend using a diluted solution with half-strength fertilizer and reducing frequency to once a month.

Is it possible to over-fertilize indoor plants?

Yes, over-fertilizing indoor plants can do more harm than good. Too much fertilizer can cause root burn, leaf scorching, wilting, or even death. The buildup of excessive salts can also damage the soil structure, affecting plant growth. Therefore, it is crucial to follow the instructions on the plant food package, including the amount and frequency of application.
