Origin and History

Philodendron lacerum

Philodendron Lacerum shares a dense history. Heinrich Wilhelm Schott explained the species scientifically first in 1829. As its name suggests, the origins of this plant can be traced down to the genus Philodendron.

It is a purely epiphyte exotic plant that loves to grow in tropical or sub-tropical areas, where moisture remains compacted in the air. It belongs to the Araceae family and can be looked up in the deep forests of South America, including Jamaica, Costa Rica, and Panama.

It is known for its foliage since the leaves spread out so that it gives an elephant ear shape, which is how it got its common name, i.e., elephant ear plant and toothed Philodendron.

Philodendron Lacerum Care Guide


Your Philodendron Lacerum is versatile when it comes to its light requirements. It can tolerate well in all types of lights, which is how it is perfect for keeping indoors and outdoors; since it is a tropical plant, damp low lights or bright indirect sunlight suits it well.

However, it is crucial to know the light requirements of your particular Philodendron before the purchase to ensure it doesn’t get too little or too much light. Try to avoid sudden changes concerning light to prevent sunburns or withering.

A window receiving damped sunlight will be a good option for your plant. Avoid exposing it to direct sunlight, as it can burn the leaves. Also, don’t place it in too low light. It will make the plant leggy.

I like to use a grow light for my Philodendron Lacerum. I find that it helps the plant to grow faster and stay healthier.

If you live in an area that doesn’t get much sunlight during the winter, then a grow light can be a great way to ensure your Philodendron receives the light it needs.


A tropical plant like Philodendron Lacerum stays healthy if you provide ample, rich organic soil to complement its growth. If the soil is too moist or too dry, it could stunt the plant’s growth and may result in root rot.

Therefore, a good potting mix with parts of peat moss, perlite, and bark will do the trick just fine. Also, ensure the pot has drainage holes at the bottom to avoid water-logging.

I often use a bit of charcoal to help with drainage and to keep the potting mix fresh. The peat moss is suitable for holding moisture well and is also rich in nutrients. The perlite helps with drainage and aeration, while the bark provides structure.

Quality soil helps keep air circulation while allowing excess water to drain through the pot. Considering its growth pattern, you can also place a mossy pole or burlap for the plant to climb over it.


Philodendron Lacerum requires moderate watering for its nourishment. You may need to water them more frequently in dry seasons than in moist ones.

Fill up the pot with adequate water and see if the water is draining from the pot’s end. Make sure to aerial water roots as well if present. Always check the soil before watering the plant to ensure it is dry at least 1-2 inches from the top.

Overwatering the plant might cause the roots to lose their absorption rate. Interestingly, Philodendron Lacerum can occasionally survive dry seasons, too, so you might not have to worry too much about watering it.


Philodendron Lacerum enjoys being fed with liquid fertilizers. Use organic and diluted fertilizer once every month during its active growing sessions in summers and springs.

Your plant may not require frequent fertilization during winters or falls; once every two to three months will be good enough.

Also, commercial fertilizers are often harsh and may damage the roots if given an overdose. Be mindful of diluting the feeding and water your plants before supplementing them.


Toothed philodendrons flourish well in warm and humid temperatures. If kept indoors, keep the temperature of the room between 55°F to 80°F or 18°C to 26°C.

However, if it is outdoors, ensure it isn’t too hot or dry. Keep them away from the direct scorching sun in hot seasons or ventilation systems such as air conditioners or doors during winters.

Extreme lower temperatures can hinder the plant from growing. You can enjoy healthy and stunning green foliage all year if the temperatures are proper.


Tropical plants usually thrive in moist and humid environments. For these toothed philodendrons to grow more quickly, you need to maintain an ideal humidity of around 55-65%.

It isn’t a big hustle unless you live in an arid area. Even then, you might only need to occasionally mist your plant three to four days a week or keep a shallow tray filled with water and stones below the pot to maintain ideal humidity.

You can also consider buying a humidifier as per your choice. Once again, if the plants are wilting, consider keeping them near the washing area or kitchen, where those areas are more humid.


Philodendron Lacerum care is a low-maintenance plant. You don’t need to prune it often. However, if you are keeping it indoors, you might need to prune it to keep the plant compact and in shape since it can grow up to 15 feet taller.

Otherwise, the plants rarely require trimming and happily cling to the poles or burlap. Moreover, if you see any dead, infected, or dried leaves, you need to prune them to avoid damaging the nearby fellow leaves and petioles.


Philodendron Lacerum needs space to spread its roots freely for better growth. Each year, as the plants get taller and healthier, the roots might get squeezed in and start outgrowing at the bottom of the pot.

In addition, the nutrients and minerals in the soil might be depleted by the end of each year. That is an indication for you to begin repotting. Spring is an ideal season to start repotting as the plant grows actively.

You can use a pot size inches wider and longer than the existing one. Carefully detach the roots and place them in the new pot with fresh potting soil, ideally with a blend of potassium, magnesium, nitrogen, and phosphorus.

Also, don’t forget to put little holes at the bottom of the container to ensure sufficient drainage and aeration.

Propagating the Lacerum

Try propagating if you are already impressed by your plant and want to bring another into the house.

It is a more effortless and cost-friendly way to create a beautiful plant, just like your previous one! Stem cutting is the best way to propagate your toothed Philodendron.

In early spring, cut a small piece of the stem along with its leaf and place it in a clear container filled with water.

Change the water daily with the clean one to ensure it stays decontaminated. In two to three weeks, the roots will begin to sprout, and then you can safely transfer them into a new pot. Your new healthy gorgeous-looking plant will be ready to bloom.

Pet Safety/Toxicity

Philodendron Lacerum, just like its fellow mates, has high toxicity levels. Relax! You only need to consume a sufficient amount of leaves or stems to experience any severe side effects.

However, pets are small, and thus they are prone to get poisonous if they ingest large amounts of the plant. They may experience nausea, vomiting, diarrhea, and weakness, i.e. gastrointestinal problems since it contains oxalate calcium crystals.

In case of ingestion, take your pet to a veterinarian immediately. Also, keep your pets away from Philodendron Lacerum plants as a preventative measure.
