Philodendron cordatum Care
Philodendron cordatum is a low-maintenance plant that is well-suited for beginners and experienced plant keepers alike. To keep your plant healthy and thriving, follow these care guidelines:
Light
This plant prefers bright, indirect light, but it can tolerate lower light conditions. To prevent the leaves from scorching, it’s advisable to keep it away from direct sunlight.
Soil
This plant requires a well-draining, peat-based potting mix. A good soil mixture is a combination of peat moss and perlite in the ratio of 2:1.
Water
Overwatering should be avoided, as it can result in root rot. Underwatering is less harmful to the plant than overwatering, so it is preferable to err on the side of caution and avoid overwatering.
Temperature
For optimal growth, it’s best to maintain temperatures between 65°F and 80°Fahrenheit when cultivating this plant. Sudden temperature fluctuations should be avoided, and it’s important to protect from cold drafts.
Humidity
This plant prefers moderate humidity levels, but it can tolerate lower humidity conditions. If you notice the leaves becoming dry or developing brown tips, consider increasing humidity by placing the plant on a tray of water and pebbles, using a humidifier, or misting the leaves with water.
Fertilizer
Feed with a balanced liquid fertilizer diluted to half strength every month during the growing season (spring and summer). In fall and winter, reduce fertilizing frequency to every 6-8 weeks.
Pruning and Training
Regular pruning can help maintain the desired shape and size of your Philodendron cordatum. Trim back any excessively long or leggy vines, as well as any yellowing or damaged leaves. You can also train your plant to grow up a moss pole, trellis, or other support structure by attaching the vines gently with plant ties.
Potting and Repotting Philodendron cordatum
Repot every 2-3 years or when the plant becomes root-bound. To prevent waterlogging, it’s important to select a pot that is one size larger than the current one and has drainage holes.
How to Repot (Step-by-Step)
Propagating Philodendron cordatum
Philodendron cordatum is easily propagated through stem cuttings. The best time to propagate is during late spring or early summer.
Propagating by Stem Cuttings (Step-by-Step)
- Select a stem that is healthy and has at least one leaf and a visible node, which is a small bump where a leaf or root can emerge.
- Using clean, sharp scissors or pruning shears, cut the stem about an inch below the node.
- Eliminate any leaves from the lower section of the cutting, ensuring to leave at least one or two leaves at the top.
- Place the cutting in a jar of water, making sure at least one node is submerged.
- Wait for roots to develop, which typically takes 2-4 weeks.
- Once roots are about 1-2 inches long, transplant the cutting.
- Keep the soil moderately moist and expose the cutting to bright, indirect light.
Toxicity
Philodendron cordatum, like other members of the Philodendron genus, contains calcium oxalate crystals. These crystals can be toxic to humans and pets if ingested. When chewed or swallowed, the calcium oxalate crystals can cause irritation, burning, and swelling of the mouth, lips, tongue, throat, and gastrointestinal tract.
In some cases, ingestion may also result in vomiting and diarrhea.
NOTE: This page is not intended as a substitute for veterinary advice. The toxicity of an ingested substance varies depending on the amount ingested, the animal’s weight, and its sensitivity to specific allergens. Contact your veterinarian or local animal poison control center immediately if you think your pet may have ingested a toxic substance.
Common Problems
Pests
Philodendron cordatum can be susceptible to common pests like spider mites, mealybugs, and aphids. Inspect your plant regularly and treat any infestations with insecticidal soap, neem oil, or a systemic pesticide.
Yellowing Leaves
Yellowing leaves can be indicate overwatering or poor drainage. Ensure that your plant’s soil is consistently moist but not waterlogged, and that the pot has drainage holes.
Drooping Leaves
Drooping leaves can result from underwatering. Check the soil moisture and water your plant if dry.
AVOID
- Overwatering
- Placing under harsh sunlight
- Using poorly drained potting mediums
- Fertilizing during dormancy
