The Silver Sword Philodendron (Philodendron hastatum) is a beautiful, easy-to-care-for houseplant with striking silver-toned leaves. Here’s a care guide to help you keep your plant thriving:

1. Light

• Ideal Light: Bright, indirect light.
• Tolerates: Low light but growth may slow down and the leaves may lose their vibrant silver color.
• Avoid: Direct sunlight as it can scorch the leaves.

2. Watering

• Watering Frequency: Water when the top 1-2 inches of soil are dry.
• Avoid Overwatering: Let the soil dry out a bit between waterings to prevent root rot.
• Best Practice: Water thoroughly until excess water drains from the bottom of the pot. Make sure the pot has drainage holes.

3. Humidity

• Ideal Humidity: Prefers high humidity (50% or higher), but can tolerate average levels.
• Boosting Humidity: Use a humidity tray, humidifier, or mist the leaves occasionally if the air is dry.

4. Temperature

• Ideal Range: 60-85°F (15-29°C).
• Avoid: Drafts, sudden temperature changes, and cold temperatures (below 50°F or 10°C).

5. Soil

• Soil Type: Well-draining, peat-based potting mix. A mix for aroids or a general-purpose indoor potting mix works well.
• Good Drainage: Ensure the soil is loose and airy, which helps prevent water retention.

6. Fertilizing

• Fertilizer: Use a balanced, water-soluble fertilizer diluted to half strength.
• Frequency: Fertilize every 4-6 weeks during the growing season (spring to fall). Reduce or stop during winter when the plant is not actively growing.

7. Repotting

• When to Repot: Every 1-2 years or when the plant becomes root-bound.
• Pot Size: Choose a pot that’s 1-2 inches larger than the current one to avoid too much excess soil, which can retain too much moisture.

8. Pruning

• Pruning: Regularly trim any dead or damaged leaves to keep the plant looking tidy. You can also trim back leggy stems to encourage bushier growth.
• Propagation: The Silver Sword Philodendron can be propagated by stem cuttings in water or soil.

9. Pests and Problems

• Common Pests: Aphids, spider mites, scale, and mealybugs.
• Check regularly for signs of pests or fungal issues. If pests are present, treat with insecticidal soap or wipe down the leaves with a damp cloth.
• Yellowing Leaves: Could indicate overwatering or poor drainage.
• Brown Leaf Tips: This could be a sign of dry air, underwatering, or too much direct sunlight.
