Materials & Supplies

To successfully grow and maintain your Boston fern, you’ll need the following items:

1. Boston Fern Plant: Purchase a healthy specimen from a reputable garden center or nursery.
2. Potting Container: Choose a pot with drainage holes that’s 2-4 inches larger than the root ball.
3. Hanging Basket (optional): Perfect for displaying the cascading fronds.
4. Potting Medium: Use a peat-based potting mix with added perlite for drainage.
5. Humidity Tray: A shallow tray filled with pebbles and water.
6. Spray Bottle: For misting the fronds.
7. Watering Can: Preferably with a narrow spout for controlled watering.
8. Plant Scissors or Shears: For trimming and removing dead fronds.
9. Liquid Fertilizer: Choose a balanced, water-soluble fertilizer (10-10-10).
10. Plant Saucer: To catch excess water if not using a humidity tray.
11. Plant Hanger (optional): If you prefer to hang your fern.
12. Humidifier (optional but recommended): To maintain proper humidity levels.

Timing / Growing Schedule

Boston ferns are perennial houseplants that can be purchased and grown year-round. However, timing certain care activities properly will help ensure your plant thrives:

Initial Growth Period: After purchasing, allow 2-3 weeks for your fern to adjust to its new environment before repotting.

Active Growing Season: Spring and summer (March-August) is when Boston ferns experience their most vigorous growth. This is the best time for repotting, division, and fertilization.

Dormancy Period: Growth slows during fall and winter (September-February). Reduce watering and hold off on fertilizer during this period.

Maintenance Schedule:
– Daily: Check humidity and moisture levels
– Weekly: Thorough watering and misting (3-4 times)
– Monthly: Fertilizing (during growing season only)
– Annually: Repotting (typically in spring)

Unlike seasonal garden plants, Boston ferns don’t have a definite “harvest” time they’re grown for their ornamental value year-round.

Step-by-Step Instructions

1. Selecting the Perfect Location

Find a spot with bright, indirect light. The ideal location is near an east or north-facing window where your Boston fern will receive morning light but be protected from harsh afternoon sun. Avoid direct sunlight, which can scorch the delicate fronds.

Pro Tip: If your home lacks sufficient natural light, consider supplementing with a grow light positioned 1-2 feet above the plant.

2. Potting Your Fern

1. Select a pot with drainage holes that’s 2-4 inches larger than the root ball.
2. Place a layer of peat-based potting mix in the bottom of the pot.
3. Remove the fern from its nursery container gently by turning it sideways and tapping the edges.
4. Place the fern in the new pot, ensuring it sits at the same depth as before.
5. Fill in around the root ball with fresh potting mix, leaving about an inch of space at the top.
6. Water thoroughly until water drains from the bottom.

Pro Tip: Add a layer of activated charcoal at the bottom of the pot to prevent soil souring and root rot.

3. Watering Routine

Boston ferns need consistently moist, but not soggy-soil.

1. Check soil moisture by inserting your finger about an inch into the soil. If it feels dry, it’s time to water.
2. Water thoroughly, allowing water to flow through the drainage holes.
3. Empty the drainage tray after watering to prevent standing water.
4. During active growth (spring/summer), water when the top inch of soil feels dry.
5. In dormant periods (fall/winter), allow the top two inches to dry before watering.

Pro Tip: Use room temperature water, as cold water can shock the root system. Rainwater or filtered water is preferable to tap water, which may contain chemicals that can build up in the soil.

4. Maintaining Proper Humidity

Proper boston fern care requires high humidity levels (50-80%).

1. Mist the fronds 3-4 times weekly with room temperature water.
2. Place the pot on a humidity tray filled with pebbles and water.
3. Group your fern with other plants to create a microclimate with higher humidity.
4. Consider running a humidifier nearby, especially during winter when indoor air is drier.

Pro Tip: Take your fern to the bathroom occasionally when showering; the steam provides an excellent humidity boost.

5. Fertilizing Schedule

1. During active growing season (March-August), apply a balanced liquid fertilizer diluted to half the recommended strength.
2. Fertilize monthly during this period.
3. Stop fertilizing completely during fall and winter months.
4. Resume fertilizing in early spring when new growth appears.

Pro Tip: Over-fertilizing can burn the roots and fronds, so err on the side of under-fertilizing rather than over-fertilizing.

6. Pruning and Maintenance

1. Regularly remove any brown or yellowing fronds by cutting them at the base with clean scissors.
2. Shape the plant by trimming any overly long fronds.
3. Remove any debris that accumulates in the center of the plant.
4. Every few months, gently shake or brush the fronds to remove dust.

Pro Tip: Use a soft paintbrush to dust the fronds if they become dusty, as this helps the plant photosynthesize efficiently.
