Fertilizing Houseplants: Why It’s Important and How to Do It

Fertilizing houseplants is a crucial part of plant care. It helps to ensure that your plants have the nutrients they need to grow and thrive. Houseplants grown in pots have a limited supply of nutrients. Over time, the nutrients in the potting mix are depleted, and the plants need to be fertilized to replenish them.

Here are some of the benefits of fertilizing indoor plants:

• Promotes healthy growth and development. The right fertilizer provides plants with the essential nutrients they need to grow new leaves, stems, and roots. It also helps to improve plant size and vigor.
• Increases flowering and fruiting. Fertilizers can help plants to produce more flowers and fruit. It can also improve the quality and size of blooms.
• Improves plant resistance to pests and diseases. Well-fertilized plants are healthier and more resilient, making them less susceptible to pests and diseases.
• Extends plant life. Fertilizer helps plants to stay healthy and productive for longer periods of time.

There are two main types of fertilizer

Organic vs Inorganic Fertilizer

Organic fertilizers come from plants and animals, such as manure, compost, and bone meal. Inorganic fertilizers are made from synthetic chemicals. Both can be effective, but organic fertilizers are generally considered to be better for the environment. We will talk more about Organic and Inorganic also known a synthetic fertilizer below.

Organic or Synthetic? Which should you use?

Organic fertilizers and Synthetic Fertilizers are both used to provide plants with the nutrients they need to grow and thrive. However, there are some key differences between the two types of fertilizers.

Organic fertilizers are derived from natural sources, such as plant and animal materials. They are typically slower-acting than synthetic fertilizers, but they can improve the overall health and fertility of the soil over time. Organic fertilizers also help to promote beneficial soil microbes, which can improve plant health and resistance to pests and diseases.

Synthetic fertilizers are manufactured from chemical compounds. They are typically faster-acting than organic fertilizers, and they can provide plants with a quick boost of nutrients. However, synthetic fertilizers can also damage the soil and pollute groundwater if they are overused.

Here is a table comparing organic and synthetic fertilizers:

Characteristic	Organic fertilizers	Synthetic fertilizers
Origin	Natural	Chemical
Speed of release	Slow-acting	Fast-acting
Effect on soil	Improves soil health and fertility	Can damage soil if overused
Effect on plant health	Promotes healthy growth and resistance to pests and diseases	Can provide a quick boost of nutrients
Environmental impact	Low	High if overused

When to fertilize houseplants

The best time to fertilize houseplants is during the growing season, which is typically early spring to fall. During this time, the plants are actively growing and require more nutrients. During the winter months your Monstera might be growing as quickly so diluting your fertilizer down during this time is important.

How to fertilize houseplants

There are a few different ways to fertilize houseplants. The most common method is to use a liquid fertilizer. Liquid fertilizers are diluted with water and applied to the soil around the plant. Another method is to use a slow-release fertilizer. Slow-release fertilizers are applied to the soil and gradually release nutrients over time.

Here are some tips for fertilizing houseplants:

• Always follow the directions on the fertilizer label. Over-fertilizing can damage or kill plants.
• Water your plants before fertilizing. This will help to prevent root burn.
• Apply fertilizer to the soil around the plant, avoiding the leaves and stems.
• Water your plants after fertilizing to help distribute the nutrients throughout the soil.

If you are unsure about how often to fertilize your houseplants or how much fertilizer to apply, it is always best to err on the side of caution and use less fertilizer than you think is necessary.​

The N-P-K ratio is and How it Relates to Fertilizing:

NPK stands for nitrogen, phosphorus, and potassium. These are the three macronutrients that plants need in the largest quantities.

• Nitrogen is essential for plant growth and development. It helps plants to produce new leaves, stems, and roots.
• Phosphorus is important for root development and flowering. It also helps plants to absorb other nutrients.
• Potassium is necessary for cell growth and development. It also helps plants to resist pests and diseases.

NPK fertilizers are a common type of fertilizer that contains all three of these macronutrients. The numbers on the fertilizer label indicate the percentage of nitrogen, phosphorus, and potassium in the fertilizer. For example, a fertilizer with an NPK ratio of 10-10-10 contains 10% nitrogen, 10% phosphorus, and 10% potassium.

NPK fertilizers are available in a variety of forms, including liquid fertilizers, granular fertilizers, and slow-release fertilizers. We will go into more detail about fertilizer forms below. The best type of NPK fertilizer to use will depend on the type of plants you are growing and the needs of your soil.

Fertilizers can also be classified by their form

• Liquid fertilizers: These fertilizers are dissolved in water and applied to the soil or leaves of plants.
• Granular fertilizer: These fertilizers are in the form of small pellets that are applied to the top of the soil.
• Slow-release fertilizers: These fertilizers release nutrients slowly over time. They are often in the form of granules or tablets that are applied to the soil.

Which is the best fertilizer for Monstera depends on your individual needs and preferences. If you are looking for a fertilizer that will improve the long-term health of your soil and plants, then an organic fertilizer is a good choice. However if you are looking for a fertilizer that will provide your plants with a quick boost of nutrients, then a synthetic fertilizer may be a better option. Using a combination of both is a great way to get the best of both.

Homemade Fertilizers and How to make your own!

Here are some recipes for homemade fertilizers that you can make using common household ingredients:

Coffee grounds fertilizer

Coffee grounds are a good source of nitrogen, which is essential for plant growth. To make coffee grounds fertilizer, simply add a handful of coffee grounds to the soil around your plants. You can also water your plants with coffee grounds tea, which is made by soaking coffee grounds in water for a few hours.

Banana peel fertilizer

Banana peels are a good source of potassium, which is important for plant flowering and fruiting. To make banana peel fertilizer, dry banana peels in the oven at low heat until they are crispy. Then, grind the banana peels into a powder and add it to the soil around your plants.

Epsom salt fertilizer

Epsom salt contains magnesium, which is important for plant chlorophyll production. To make Epsom salt fertilizer, dissolve one tablespoon of Epsom salt in a gallon of water. Apply the Epsom salt solution to the soil around your plants every two weeks.

Fish emulsion fertilizer

Fish emulsion is a liquid fertilizer that is made from fish waste. It is a good source of nitrogen, phosphorus, and potassium. To use fish emulsion fertilizer, dilute it with water according to the package directions and water your plants with the diluted solution. Beware of using this fertilizer right before company comes over. The smell tends to linger for a few days.

Compost tea

Compost tea is a liquid fertilizer that is made from compost. It is a good source of all the essential nutrients that plants need. To make compost tea, steep compost in water for a few days. Then, strain the compost tea and apply it to your plants.

Worm Castings

Worm castings are the excrement of earthworms. They are a natural fertilizer that is rich in nutrients and beneficial microbes. Worm castings are dark brown or black in color and have a crumbly texture. They are odorless and easy to use.

You can also mix and match these ingredients to create your own custom fertilizer blends. 

For example, you could mix coffee grounds, banana peel powder, and Epsom salt to create a fertilizer high in nitrogen, potassium, and magnesium.

It is important to note that homemade fertilizers can vary in strength and potency. It is always best to start with a diluted solution.

The best fertilizers for monstera deliciosa are those high in nitrogen and potassium. Nitrogen is essential for leaf growth, while potassium helps to promote strong roots and stems.

Here are some specific fertilizer recommendations:

• Balanced liquid fertilizer: A balanced liquid fertilizer with an NPK ratio of 10-10-10 or 20-20-20 is a good option for monstera deliciosa plants. You can dilute the fertilizer to half-strength and apply it every two weeks during the growing season.
• Slow-release fertilizer: A slow-release fertilizer with an NPK ratio of 12-6-6 or 14-14-14 is another good option for monstera deliciosa plants. You can apply slow-release fertilizer once every three months.
• Organic fertilizer: Organic fertilizers, such as compost tea or fish emulsion, are also good options for monstera deliciosa plants. Apply organic fertilizers every two weeks during the growing season.

Fertilizing issues are one of the most common problems that houseplant owners face. Too much fertilizer, too little fertilizer, or the wrong kind of fertilizer can all damage your plants.

How to apply Fertilizers

There are two main ways to apply fertilizer to your plants: foliar feeding and soil fertilization.

Foliar feeding is the application of fertilizer directly to the leaves of a plant. This is a quick way to get nutrients into the plant, but it is important to note that not all fertilizers are suitable for foliar feeding. Be sure to read the label carefully to make sure that the fertilizer you are using is safe to apply to the leaves of your plant.

Soil fertilization is the application of fertilizer to the soil around the roots of a plant. This is a more traditional method of fertilization, and it is generally more effective than foliar feeding. However, it is important to note that it can take longer for the nutrients to reach the plant when they are applied to the soil.

Here are some specific tips for foliar feeding:

• Dilute the fertilizer to half strength. This will help to prevent leaf burn.
• Apply the fertilizer to the underside of the leaves. This is where the plant’s stomata are located, and where the nutrients will be absorbed most easily.
• Avoid applying fertilizer in direct sunlight. This can also cause leaf burn.

Here are some specific tips for soil fertilization:

• Apply the fertilizer to the soil around the base of the plant. Avoid applying fertilizer directly to the stem of the plant.
• Gently water the fertilizer into the soil. This will help to distribute the nutrients throughout the soil.
• Fertilize your plants regularly during the growing season. However, reduce or stop fertilizing during the dormant season.

Here are some of the most common fertilizing issues with Monstera:

• Fertilizer burn: This is caused by using too much fertilizer, or by using a fertilizer that is too strong. Symptoms of fertilizer burn include browning leaf margins, leaf scorch, and leaf drop.
• Nutrient deficiency: This is caused by not fertilizing enough, or by using a fertilizer that does not contain the nutrients that your plant needs. Symptoms of nutrient deficiency vary depending on the nutrient that is missing but can include yellowing leaves, stunted growth, and poor flowering.
• Salt buildup: This can occur when you use water-soluble fertilizers that contain high levels of salts. Symptoms of salt buildup include white crusty deposits on the soil surface, browning leaf margins, and leaf drop. Flush your plant with water every few months to remove buildup.

If you suspect that your plant has a fertilizing issue, you can take the following steps:

• Identify the problem. Is the plant over-fertilized, under-fertilized, or suffering from salt buildup?
• Take corrective action. If the plant is over-fertilized, flush it with water and reduce or stop fertilizing. If the plant is under-fertilized, start fertilizing with a balanced fertilizer. If the plant is suffering from salt buildup, flush it with water more frequently.
• Be patient. It may take some time for your plant to recover from a fertilizing issue.
