Boston Fern Green Plant

The Boston Fern (Nephrolepis exaltata ‘Bostoniensis’) is a lush, classic indoor plant known for its graceful, arching fronds. It’s a bit finicky but thrives beautifully once you understand its needs.

🌱 Boston Fern Indoor Care Guide

1. Light

• Needs: Bright, indirect light — ideally near an east- or north-facing window.
• Avoid: Direct sunlight (can scorch leaves) and dark corners (leads to sparse growth).
• Tip: Filter harsh light with a sheer curtain if placed near a sunny window.

2. Temperature & Humidity

• Ideal Temperature: 60–75°F (16–24°C).
• Avoid: Cold drafts, AC vents, or heat sources — Boston ferns are sensitive to temperature swings.
• Humidity: High humidity (≥ 50%) is essential!
  • Use a humidifier, pebble tray, or place in a bathroom with bright light.
  • Mist daily in dry climates (especially in winter).

3. Watering

• Keep soil: Consistently moist, never soggy or bone dry.
• Check soil: Water when the top ½–1 inch feels dry.
• Best method: Water thoroughly until it drains out of the bottom, then empty saucer.
• Tip: Reduce watering slightly in winter, but never let soil dry completely.

4. Soil

• Type: Light, rich, well-draining mix.
  • Mix 2 parts peat moss or coco coir, 1 part perlite, 1 part pine bark or compost.
• pH: Slightly acidic (5.0–6.5).

5. Fertilizer

• When: Every 4 weeks during spring and summer.
• Type: Diluted balanced liquid fertilizer (e.g., 10-10-10) at half strength.
• Winter: Stop fertilizing when growth slows.

6. Pruning

• Remove yellow or brown fronds regularly.
• Trim back old, dry fronds to encourage fresh growth.
• Use clean scissors and prune in spring if it looks overgrown.

7. Repotting

• When: Every 1–2 years, in spring.
• Signs: Roots poking out of drainage holes, fronds yellowing, or slow growth.
• How: Move to a pot just 1–2 inches larger. Avoid oversized pots (they stay too wet).
