The Best Fertilizer for Monstera Adansonii

Monstera Adansonii is a gorgeous, fenestrated tropical plant that is also known as the Swiss cheese plant. Monsteras are popular indoor plants, loved by many all over the world. 

Monstera Adansonii Characteristics

 The Adansonii is a fast-growing vining plant that can reach up to 30 feet in length in its natural habitat, but it is typically grown as a potted plant indoors. Many do not reach 30 feet indoors, but with the right care I bet they could! They are one of many tropical plants that climb using aerial roots. These aerial roots allow them to climb any surface they choose, even buildings!

Although Monstera is easy to care for, it needs regular fertilization to meet its nutritional needs.

Monstera Adansonii is relatively easy to grow which makes it an awesome choice for beginner plant parents. It prefers bright, indirect light and moist soil. It is also relatively pest and disease resistant.

The most effective way to choose the best fertilizer for Monstera Adansonii is to gain a deeper understanding of fertilizers in general, and I can help you with that!

Let’s start with the different forms of fertilizers

Organic granular fertilizer: These fertilizers are slow-release, which means they release nutrients over time, preventing nutrient burn. A balanced fertilizer with an NPK ratio of 10-10-10 or 20-20-20 is a good option. Apply every 6-8 weeks during the growing season.

Slow-release fertilizer sticks: These pre-measured sticks are easy to use and provide a steady supply of nutrients for several months. Apply once every 2-3 months during the growing season.

Water-soluble or liquid fertilizer: These fertilizers are quick-acting and can be used to give your Monstera Adansonii a boost of nutrients. Dilute the fertilizer to half-strength and apply every 2-4 weeks during the growing season.

Compost or worm castings: These organic amendments provide a slow release of nutrients and improve soil health. Top-dress your Monstera adansonii with a layer of compost or worm castings every few months.

Here are some additional tips for fertilizing Monstera Adansonii:

• Do not fertilize at full strength during the winter when the plant is dormant.
• Fertilize less often if your Monstera Adansonii is young or pot-bound.
• Watch for signs of nutrient deficiency, such as yellowing leaves.
• Avoid over-fertilizing, as it can cause fertilizer burn.

What is NPK and why you need to know about it:

NPK stands for nitrogen (N), phosphorus (P), and potassium (K), which are the three primary macronutrients essential for plant growth. 

These nutrients are often listed on fertilizer labels in a specific ratio, such as 10-10-10 or 20-20-20. The numbers represent the percentage of each nutrient in the fertilizer by weight.

• Nitrogen (N): Nitrogen is crucial for leaf growth and development. It promotes lush green foliage and helps plants absorb other nutrients.
• Phosphorus (P): Phosphorus is essential for root growth and development. It also plays a role in flower and fruit formation.
• Potassium (K): Potassium strengthens plant stems and roots, making them more resistant to diseases and environmental stresses. It also helps regulate water balance in plants.

The specific NPK ratio of a fertilizer depends on the type of plant you are growing and its stage of development. For instance, leafy greens like lettuce and kale require more nitrogen, while flowering plants like tomatoes and peppers need more phosphorus.

Here’s a general guideline for NPK ratios based on plant type:

• Leafy greens: 20-10-10 or 25-8-9
• Flowering plants: 10-20-10 or 12-24-12
• Fruiting plants: 15-15-15 or 17-17-17
• Fruit trees: 10-10-10 or 12-12-12

When selecting a fertilizer, consider the specific needs of your plants and the overall health of your soil. Always follow the application instructions on the fertilizer label to avoid over-fertilizing, which can damage plants.

Synthetic Fertilizers VS Organic Fertilizers

Synthetic and organic fertilizers are both used to provide plants with essential nutrients, but they differ in their origin, composition, and effects on the environment.

Origin

• Synthetic fertilizers: Also known as inorganic fertilizers, these are manufactured from chemicals and minerals. They are typically produced in industrial settings and involve chemical processes.
• Organic fertilizers: Derived from natural sources, such as plant and animal waste, compost, and manure. They are often produced through composting or other methods that involve the breakdown of organic materials.

Composition

• Synthetic fertilizers: Contain specific nutrients in precise ratios, typically nitrogen (N), phosphorus (P), and potassium (K). They are often concentrated and readily available for plant uptake.
• Organic fertilizers: Contain a variety of nutrients, including N, P, and K, but may also contain micronutrients and other beneficial compounds. They release nutrients slowly over time, as they are broken down by soil organisms.

Effects on the environment

• Synthetic fertilizers: Can have potential environmental impacts, such as nutrient runoff into waterways, which can lead to algal blooms and oxygen depletion. They may also contribute to soil acidification.
• Organic fertilizers: Generally considered more environmentally friendly as they promote soil health, improve soil structure, and increase microbial activity. They are less likely to cause nutrient runoff or soil acidification.

Suitability for different plants

• Synthetic fertilizers: Suitable for plants that require a quick boost of nutrients, especially during the growing season. They can be particularly effective for crops and fast-growing plants.
• Organic fertilizers: Suitable for plants that prefer a slow and steady release of nutrients and thrive in healthy soil conditions. They are often preferred for organic gardening and for plants that are sensitive to salt buildup.

Synthetic fertilizers offer a quick and concentrated source of nutrients, while organic fertilizers promote long-term soil health and provide a more gradual nutrient release. 

The choice between synthetic and organic fertilizers depends on various factors, including plant type, soil conditions, environmental considerations, and personal preferences.

When is the best time to begin fertilizing your monstera? Now is a great time but if you want to wait to formulate a fertilizer plan you can wait until early spring when the plant is in active growth. 

Different Fertilizer options

Balanced liquid fertilizer: A balanced liquid fertilizer with an NPK ratio of 10-10-10 or 20-20-20 is a good all-purpose fertilizer for Monstera adansonii. Dilute the fertilizer to half strength and apply it every 2-4 weeks during the growing season.

Fish emulsion fertilizer: Fish emulsion fertilizer is a natural and organic fertilizer that is rich in nitrogen and phosphorus. It is a good choice for Monstera adansonii that are showing signs of nutrient deficiency, such as yellowing leaves. Mix fish emulsion fertilizer with water according to the instructions on the label and apply it every 4-6 weeks during the growing season.

Slow-release granular fertilizer: Slow-release granular fertilizer is a convenient option that provides nutrients to your Monstera adansonii over time. The best time to apply slow-release granular fertilizer is every 3-6 months during the growing season.

Compost or worm castings: Compost and worm castings are organic amendments that provide a slow and steady release of nutrients to your Monstera adansonii. They also help to improve soil structure and drainage. Top-dress your Monstera adansonii with compost or worm castings every few months.

Here are some additional tips for fertilizing Monstera adansonii:

• Do not use a full dose of fertilizer on your Monstera adansonii during the winter months when it is no in active growth.
• Fertilize less often if your Monstera adansonii is young or pot-bound.
• Watch for signs of nutrient deficiency, such as yellowing or browning leaves, before fertilizing.

Liquid Fertilizer VS Granular Fertilizer

Liquid and granular fertilizers are both effective ways to provide plants with essential nutrients, but they have different properties and applications.

Liquid fertilizer

• Appearance and application: Liquid fertilizer is a concentrated solution of nutrients dissolved in water. It is typically applied through a hose attachment or watering can.
• Nutrient release: Liquid fertilizer provides nutrients quickly and efficiently, making it ideal for situations where a quick boost of nutrients is needed.
• Convenience: Liquid fertilizer is easy to apply and can be mixed with water to adjust the nutrient concentration.
• Shelf life: Liquid fertilizer typically has a shorter shelf life than granular fertilizer.

Granular fertilizer

• Appearance and application: Granular fertilizer is made up of small, dry pellets that contain concentrated nutrients. It is typically spread over the soil surface and watered in.
• Nutrient release: Granular fertilizer releases nutrients slowly over time, making it a good choice for long-term nutrient supply.
• Cost-effectiveness: Granular fertilizer is often more cost-effective than liquid fertilizer, especially when purchased in bulk.
• Storage: Granular fertilizer has a longer shelf life than liquid fertilizer.

Choosing the right fertilizer

The best type of fertilizer for your plants depends on several factors, including the type of plants, the time of year, and your personal preferences. 

Here are some general guidelines:

• Use liquid fertilizer for plants that need a quick boost of nutrients or that are sensitive to salt buildup.
• Use granular fertilizer for plants that need a long-term supply of nutrients or that are not sensitive to salt buildup.
• Always follow the instructions on the fertilizer label to avoid over-fertilizing.

How to make your own Fertilizer

Making your own fertilizer is a great way to save money, reduce waste, and give your plants a boost of nutrients.

How to Grow Monstera Adansonii:

Lighting

Monstera adansonii prefers bright, indirect light. Place it near a window, but avoid direct sunlight, which can scorch the leaves. If you don’t have a bright window, you can supplement it with a grow light.

Watering

Water your Monstera adansonii when the top inch of soil is dry to the touch. Water thoroughly until water runs out of the drainage holes. Do not let the plant sit in water, this can lead to root rot.

Humidity

Monstera adansonii likes humidity. Mist the leaves regularly, especially during the winter when the air is dry. You can also place the pot on a pebble tray filled with water or add in a humidifier for higher and consistent humidity.

Maintaining consistent humidity for houseplants is essential for their health, as many tropical and subtropical plants come from humid environments.

5 Ways to increase humidity around your houseplants:

1. Grouping plants: Place your plants together to create a microclimate with higher humidity. As plants transpire, they release moisture into the surrounding air, increasing the overall humidity level.
2. Pebble trays: Fill a shallow tray with pebbles or gravel and place your plants on top. Pour water into the tray until the pebbles are partially submerged. The water will evaporate, increasing humidity around the plants.
3. Misting: Regularly mist your plants with a spray bottle filled with room-temperature water. Misting directly onto the leaves and around the plant will provide a quick boost of humidity.
4. Humidifier: Invest in a room humidifier to increase the overall humidity level in your home. Place the humidifier near your plants to ensure they receive adequate moisture.
5. Place plants in humid rooms: Consider placing your plants in naturally humid rooms, such as bathrooms or kitchens, where moisture is more prevalent.

Soil

Monstera adansonii prefers a well-draining potting mix. You can use a commercial potting mix made for tropical plants or make your own by mixing equal parts potting soil, perlite, and peat moss.

Pruning

Prune your Monstera adansonii to control its size and shape. You can also prune to remove any yellow or damaged leaves.

Pests and diseases
