    Features of Philodendron Acutatum Schott

    What makes this particular plant so special? For starters, its petioles are obtusely flattened adaxially, which means they are flat on one side and rounded on the other. The leaf blades are medium green, sub coriaceous and semi-glossy, making them a great addition to any indoor space.

    The name “Philodendron” comes from the Greek words “philo” and “dendron,” which mean “loving” and “tree,” respectively. This is a fitting name for a plant that has thrived in trees in its natural habitat.

    Speaking of natural habitat, it’s important to note that the conditions in which a plant grows are crucial to its survival. While there are no difficult plants, recreating the conditions of a tropical plant’s natural environment can be challenging.

    Natural Conditions

    In their original environment, most plants are not found on the ground, but instead, they grow on trees or other structures. These plants thrive in the moist environment of rainforests, and they need plenty of water for survival. However, they also enjoy drying time in between downpours. When we grow these types of plants indoors, we often label them as “low-light” plants. However, it’s important to note that even the brightest artificial light can’t compare to the natural shade found in the forest. Additionally, young plants will often seek out shade in order to climb onto a sturdy structure, like a tree trunk. This is because the higher levels of the forest have more sunlight.

    It’s difficult to create these exact conditions in our homes, but we can try our best to emulate them for the health and wellbeing of our plants.

    How to care for Philodendron Acutatum

    Tropical plants, like most Philodendrons, have adapted to living in various conditions, including various climates and light conditions. However, bringing one of these plants home requires some effort to make sure they thrive in your environment. Just because a plant is resilient doesn’t mean it can handle any conditions thrown it’s way.

    So, how can you take care of Philodendron Acutatum Schott? Here are some tips:

    Light requirement for

    Philodendron Acutatum needs bright but indirect light. Direct sunlight can scorch the leaves, while too little light can cause stunted growth.

    It is highly recommend investing in grow lights, especially during the winter when natural sunlight is scarce. This will provide your plants with the necessary light to grow and flourish. While window sills may work during spring and summer, it’s important to note that direct sunlight can be harmful to some plants.


    what temperature Philodendron Acutatum needs to grow healthy and strong?

    In general, it’s better to keep the temperatures slightly cooler than to overheat your Philodendron Acutatum. However, the advice of 17-27 degrees is just a broad generalization that might not be suitable for your plant’s specific needs. To find out about the ideal temperature for your Philodendron Acutatum, it’s best to read about its geographical range and preferences.

    Understandably, it’s impossible to provide significant temperature differences within the home environment. But you can make subtle changes to ensure that your plant has better-growing conditions. For instance, a slightly cooler room, a glass cabinet, a terrarium, or a windowsill in a warm and humid bathroom are all varied “environments” that you can consider for your Philodendron Acutatum.

    Watering requirement for Acutatum Philodendron

    Are you struggling to figure out when to water your Philodendron Acutatum plant? Well, you might have been told to water it when the top two centimeters of the medium are dry. However, we believe this advice can be risky because there are various mediums and growing conditions.The amount of water, how and when you water your plant cannot be a one-size-fits-all solution. It all depends on the medium, age, size of your plant, and the pot’s size and material. In essence, you have to monitor and understand your plants to know the right watering schedule.

    Philodendron Acutatum plants need water regularly, and they love to be watered or showered often. But, they don’t enjoy having “wet feet” or sitting in a puddle.

    Remember, the watering schedule is closely related to the medium you use in the first place. So, take your time, observe your plant, and learn its needs to keep it hydrated and happy.


    Repotting your Philodendron Acutatum is essential for its growth and health. You should repot it every two years or so to provide enough space for its roots to spread and to replenish nutrients. Here’s what you need to do to repot your plant:

    Step 1: Choose the Right Pot

    Choose a pot that is a few inches wider and deeper than the previous one. Additionally, choose a well-draining container to avoid potential root rot. Terra-cotta or ceramic pots are the best options because they provide airflow and drainage. Still, any container with drainage holes will suffice.

    Step 2: Fill the Pot with Soil

    To repot, start by filling a third of the pot with peaty potting soil. This soil retains moisture, which is essential for your Philodendron Acutatum.

    Step 3: Anchor the Stem

    Set up a stake for the stem to climb up and anchor it gently. This step is important to avoid damage or potential breakage, especially if your plant’s stem is already growing in a certain direction.

    Step 4: Place the Roots and Fill the Pot

    Carefully put the roots into the pot and fill the remaining space with potting soil. Ensure that you do not cover the stems with soil, as it can lead to rot. Instead, pack the soil securely in the stake area and use plant ties to attach the stem to the stake.

    Humidity requirement

    Philodendron Acutatum came from rainforests, and as you can imagine, high humidity is essential to their well-being. While some plants may be able to survive in lower humidity levels, we’re talking about optimal conditions here.

    One way to increase humidity is through misting and showering. Yes, you read that right – showering! Plants absorb nutrients and water through their leaf blades, not just their roots. In their natural environment, these plants are used to frequent rains and being completely soaked in water before drying in the wind again. If you’re not a fan of misting, a shower once in a while will also do the trick and help remove dust and mineral residue.

    TIP: A humidifier, pebble tray, or misting can help recreate the tropical environment it thrives in.


    Fertilizing your Philodendron Acutatum is important as it helps it grow and thrive.There are many fertilizers available in the market but experimenting and adjusting your fertilization practices is the best way to care for your plant.

    One important piece of advice is to foliar feed your plant. This is how plants receive their nutrients in nature. Foliar feeding involves using special fertilizers to spray your plants with.

    It is also important to check and adjust the pH levels of your watering and fertilizing solution to ensure that your plant is receiving the right amount of nutrients.

    You should also check and adjust TDS and EC of your watering and fertilizing solution to help enhance your plant’s growth.

    Using a good and proven base root fertilizer is also important. You can also consider using additives to improve your plant’s overall health.

    Perfect Soil

    One factor that can make or break your plant’s growth is the type of substrate or medium used. In particular, there is a debate between organic and inorganic substrates. For those using a passive hydroponic system like ourselves, inorganic substrates tend to react better with the system. However, that doesn’t mean non-organic substrates can’t be effective. With proper care and a well-planned fertilizing schedule, non-organic substrates can provide almost full control over plant growth and even pest control.

    What is non-organic media?

    In simple terms, non-organic media refers to a variety of inorganic materials that are used as growing mediums for plants.

    lava stones, pumice, perlite

    Some of the most common non-organic media include perlite, lava stones, and pumice. These materials are lightweight and porous, which makes them an excellent choice for hydroponic gardening and other forms of indoor cultivation. They provide good aeration and drainage, which aids in the oxygenation of plant roots and prevents waterlogging.


    Another popular non-organic medium is vermiculite, which is a natural mineral that is used to improve soil texture and moisture retention. It is also commonly used in seed-starting mixes and as a top dressing for container plants.

    Expanded clay aggregate

    This non-organic medium is widely used in hydroponics systems. It is made from fired clay and has a unique structure that promotes excellent drainage and aeration. It is pH-neutral and does not decompose, making it a popular choice for long-term growth.

    Mineral wool

    This is a synthetic material that is derived from rock and has excellent insulation properties. It is widely used in hydroponic growing as it helps to regulate temperature and humidity levels within the growing environment. It is also highly absorbent and provides good aeration.

    Polyurethane foam

    One more non-organic medium that is commonly used in hydroponic gardens. It is lightweight, porous, and provides excellent insulation. It is also moisture-resistant, making it ideal for use in humid environments.

    expanded polypropylene balls or flakes

    They are lightweight and highly porous, making them an excellent choice for hydroponic farming. They are also chemically inert, which means they won’t affect the pH levels of the nutrient solution.

    The main purpose of a growing medium is to provide a place for plant roots to anchor while also retaining moisture. Potting mixes and soils usually come pre-charged with nutrients and amendments. They can be considered the opposite of an inert medium.

    When it comes to aroids, having a well-draining and quick-drying medium is essential. Good air circulation is also key to preventing moisture build-up. If the media is too tightly packed or kept constantly wet, it can spell disaster for most plants.

    If you currently have a potting mix that has proven successful in promoting fast growth for your plants, it’s best to continue using it. Homes vary in their environmental conditions, and each person may have their own methods for growing and propagating plants. It’s crucial to experiment and determine what works best in your specific environment, and to strive to provide your plants with the optimal conditions based on what you’re capable of providing.


    Pruning philodendron

    To keep your Philodendron Acutatum looking good, trim any long aerial roots. You can choose to cut them or tuck them back into the pot. Don’t worry about them damaging surfaces in your home. If you trim the stems and leaves, they will grow back even better. You can even use the cuttings to start a new plant.


    Would you like to propagate your Philodendron Acutatum? It’s easy! You can do it through stem cuttings or air layering.

    For stem cuttings, find a stem with a node, aerial root, and at least two leaves. Cut the stem with a clean, sharp pruning shear, then sprinkle ground cinnamon on the cut to prevent disease. Place the cutting in a glass of water and change the water every so often until roots grow. Once roots appear, transfer the cutting to a pot with fresh soil.

    If you prefer air layering, find a stem with a node or a leaf with a short aerial root. Make a small notch below the root, then wrap sphagnum moss around the stem. Moisten the moss with water and cover it with plastic wrap. Wait a few months for roots to grow, then cut the stem below the roots and transfer to a pot with fresh soil.

    Is Philodendron Acutatum Toxic to Pets?

    It’s worth noting that Philodendron Acutatum leaves can cause discomfort if ingested by pets or young children. It’s best to keep the plant away from them.

    Common Issues with Philodendron Acutatum

    Philodendron Acutatum is generally an effortless plant to tend to, but it may encounter some issues. Below are some of the common issues that it may face and how to handle each situation.


    Mealybugs, thrips, scale insects, spider mites, and aphids might invade and damage the Philodendron Acutatum plant. However, wiping the leaves with a damp sponge or paper towel can stop them. If you notice these pests on the plant, spray it with water or use insecticidal soap to wash the leaves. This will keep the plant healthy and pests away.

    Browning Tips

    If the edges of the plant’s leaves turn brown, it is a sign that the soil may be too dry, or it needs more watering. Remove and discard the affected leaves. If there is a yellow ring around the brown areas, it could be due to fungal growth. Remove the affected leaves and let the plant dry out before watering it again since overwatering or keeping the soil too damp may have caused the fungus.

    Yellow Leaves or Light Brown Spots

    Yellow leaves may indicate that the soil is dry. The oldest leaves on the plant are typically affected first. Remove and discard the affected leaves. Check the soil and give the plant a good watering if it has turned bone dry. If you spot dry, crispy spots on the leaves, also check the soil.

    Wilting, Curling, or Drooping Leaves

    Wilting leaves may result from water problems, and the plant could be either overwatered or underwatered. If the first few inches of soil are dry, it is likely that the plant is underwatered. Curling leaves are caused by low humidity, and placing the plant near a humidifier can solve the problem. In extreme cases, assessing the roots may be required. Overwatering the plant could result in root rot, in which case cleaning up the roots, pruning out the rotten parts, and repotting the plant with fresh soil may be necessary.
