Philodendron Subhastatum

Size: Single Plant | 2.5″ Pot Included | Secure Packing

The Philodendron Subhastatum is a beautiful, easy-to-care-for houseplant, known for its green leaves with striking red undersides.

Here’s a comprehensive guide to Philodendron Subhastatum’s care:

1. Light:

• Bright, indirect light is ideal. This promotes faster growth and more vibrant leaf color, especially for any variegation.
• It can tolerate medium light conditions, but growth may be slower.
• Avoid direct sunlight, as it can scorch the leaves.
• Good locations include east or north-facing windows, or a spot near a south or west-facing window with a sheer curtain to filter the light.

2. Watering:

• Allow the top 1-2 inches (2.5-5 cm) of soil to dry out between waterings. You can check this by sticking your finger into the soil.
• It prefers consistently moist soil but not wet or soggy. Overwatering can lead to root rot, which is a common issue for philodendrons.
• Reduce watering frequency during winter when the plant’s growth slows.
• Ensure the pot has drainage holes to prevent water from sitting in the bottom.
• If your plant is drooping, it could be a sign of either over or underwatering, so always check the soil moisture.

3. Humidity:

• Philodendron Subhastatum appreciates average to high humidity, as it’s native to tropical forests.
• Average household humidity is usually sufficient, but occasional misting can help leaves grow larger.
• Placing it near a humidifier or on a pebble tray with water can also boost humidity.

4. Soil:

• Use a loose, well-draining potting mix that is rich in organic matter.
• A good mix might include:
  • Potting soil (40%)
  • Coco peat/peat moss (25-30%)
  • Organic manure/vermicompost (25%)
  • Perlite/pumice (5-20%)
  • Charcoal chips (5%)
• A balanced acidic soil (pH 6-6.5) is beneficial.
• It’s important that the soil drains well to prevent root rot.

5. Temperature:

• Philodendron Subhastatum thrives in warm temperatures, ideally between 18°C to 25°C (64-77°F).
• Avoid sudden temperature fluctuations.

6. Fertilizer:

• Fertilize once or twice a month during the spring and summer (growing season).
• Use a balanced liquid houseplant fertilizer (e.g., 20-20-20 NPK ratio).
• You can also supplement with calcium and magnesium, which are important for healthy leaf development.
• Reduce or stop fertilizing during the fall and winter when growth slows.
• Wait at least one month before fertilizing a newly transplanted or young philodendron.

7. Pruning:

• Pruning isn’t strictly necessary but can be done to maintain the plant’s shape, control its size, or remove leggy growth.
• The best time for pruning is early spring or fall.
• Always remove any yellow or damaged leaves.

8. Repotting:

• Repot your Philodendron Subhastatum every 1-3 years, or when it becomes root-bound and outgrows its current pot.
• The best time to repot is in the spring.
• Choose a pot that is at least 2 inches larger than the current one.

9. Propagation:

• Philodendron Subhastatum is relatively easy to propagate from stem cuttings.
• In water:
  1. Take a healthy stem cutting about 6 inches long with a few leaves, cutting just below a leaf node.
  2. Remove the leaves from the bottom half of the cutting.
  3. Place the cutting in a glass of water, ensuring the nodes are submerged.
  4. Place in a warm spot with bright, indirect light. Change the water if it becomes cloudy.
  5. Roots should appear within a few weeks. Once they are at least an inch long, you can plant the cutting in soil.
• In soil:
  1. Take a similar stem cutting as for water propagation.
  2. Remove leaves from the lower half.
  3. Plant the cutting in a well-draining potting mix, ensuring the nodes are below the soil surface.
  4. Keep the soil evenly moist and provide bright, indirect light.
  5. Gently tug on the cutting after a few weeks; resistance indicates root development. New leaf growth is also a sign of successful rooting.

10. Pests and Diseases:

• Common Pests: Watch out for aphids, mealybugs, spider mites, and scale insects. Inspect your plant regularly, especially the undersides of leaves. Treat with insecticidal soap, neem oil, or by manually removing pests.
• Common Diseases:
  • Root Rot: Primarily caused by overwatering. Symptoms include yellowing leaves, mushy roots, and wilting. If detected, remove the plant, trim affected roots, and repot in fresh, well-draining soil.
  • Leaf Spot Diseases: Can be bacterial or fungal, appearing as brown or black spots on leaves. Ensure good air circulation and avoid overwatering.
  • Nutrient Deficiencies: Yellowing leaves can indicate a lack of magnesium or iron.
• Good air circulation and proper watering practices are key to preventing most diseases.

By following these care guidelines, your Philodendron Subhastatum should thrive and bring a touch of tropical beauty to your home.
