As a cultivator of the heartleaf philodendron, philodendron Brasil are considered mildly toxic to pets and humans. While philodendron Brasil are not prone to any particular pests or diseases, keep an eye out for some common houseplant pests such as mealybugs, scale, spider mites, and fungus gnats. Regularly inspecting your plants for pests; proactive treatment is the key to preventing infestations.
Light
Philodendron Brasil can survive in a range of lighting conditions but will show its variegation best in bright, indirect light. Low-light conditions will cause the variegation to begin reverting and may result in leggy growth. You should also avoid exposing your philodendron Brasil to prolonged periods of direct sunlight as this can burn the leaves.
Soil
A loamy, well-draining soil mix that is slightly acidic is ideal for this tropical aroid. While philodendron Brasil can survive in a standard indoor potting mix, it will thrive in a mix that is designed for aroids. Try mixing together 1 part potting soil, 1 part perlite, and 1 part orchid bark for a well-draining mixture that your philodendron Brasil will love.
Water
Allow the top 2-3 inches of soil to dry out between waterings and then water well. Philodendron Brasil are sensitive to overwatering and should never be left in soggy soil for extended periods of time.
Temperature and Humidity
Native to the tropical rainforests of South America, philodendron Brasil grow best in warm, humid conditions. That being said, they do well growing indoors in typical household temperature and humidity levels, although providing your Brasil with extra humidity will encourage larger and more vigorous growth. These philodendrons are not cold tolerant and should never be left in temperatures below 55-60 degrees Fahrenheit.
Fertilizer
During the growing season philodendron Brasil benefit from regular applications of a balanced liquid fertilizer, although they will continue to grow well without fertilizer as well. Apply the fertilizer once a month during the spring and summer months, and stop fertilizing altogether in the fall and winter as the plant enters dormancy.
Pruning
Under the right conditions, philodendron Brasil are fast-growers and may require some pruning in order to keep their size manageable indoors. Pruning also helps to encourage fuller growth and larger leaves. Pruning should be done in the spring or early summer while your philodendron Brasil is actively growing. Using a pair of clean, sharp scissors or pruning shears prune any stems that are particularly long or unruly, or have started to grow small leaves. Set the stem cuttings aside—you can use them for propagation.
Propagating Philodendron Brasil
As with many plants in the philodendron genus, philodendron Brasil can be propagated by stem cuttings. Propagating is a great way to start new plants, or create a fuller plant by rooting the cuttings and then planting them back in the original pot. Here is how you can stem propagate your philodendron Brasil in just a few easy steps:
Common Problems With Philodendron Brasil
Philodendron Brasil are low-maintenance plants that are generally problem-free when grown under the right conditions. However, you may notice some of these common problems if something is off with your watering schedule or lighting conditions.
Curling Leaves
Curling leaves are an indication that your plant is not receiving enough water. Ensure that you are watering once the top couple inches of soil have dried out, and avoid letting your plant sit in fully dry soil for too long. Sometimes, if you forgot to water your plant for an extended period of time, the roots of your plant may have dried up meaning it can’t absorb water even when it is watered now. If this is the case, you will need to regrow the roots in order to save your plant, which can be done by following the stem cuttings propagation steps.
Browning Tips
Browning leaf tips can be a result of a couple of different things. Usually, it’s a result of your philodendron being exposed to overly dry conditions. Ensure that you don’t have an air vent blowing directly on the leaves, and consider providing your plant with extra humidity using a pebble tray or humidifier. Browning tips can also be a result of too much direct sunlight which has resulted in burnt leaves. Lastly, browning leaves can be a result of a lack of watering. Ensure that you don’t allow your Brasil to dry out too much between waterings.
