Understanding Boston Fern Plant Growth Stages:
A Comprehensive Guide

Updated: May 8, 2023

Boston ferns are one of the most popular houseplants, thanks to their beautiful, lush foliage and easy-to-care-for nature. However, if you want to keep your Boston fern healthy and thriving, it’s important to understand the different growth stages that your plant will go through. In this comprehensive guide, we’ll walk you through each stage of Boston fern plant growth, from planting to maturity, and provide tips for caring for your fern at every step of the way.

Stage 1: Planting Your Boston Fern

The first stage of Boston fern growth starts with planting. When you bring home a new Boston fern, it’s important to choose a location that provides the right amount of light and humidity. Boston ferns prefer bright, indirect light and high humidity levels. They also like well-draining soil that’s rich in organic matter. When planting your fern, be sure to choose a pot that’s slightly larger than the root ball so that there’s room for the roots to grow.

Stage 2: Early Growth

During the early growth stage, your Boston fern will start to establish its roots in its new pot. It’s important to keep the soil moist but not waterlogged during this stage. Overwatering can lead to root rot, which can be fatal for your plant. As your fern starts to grow new fronds, you may notice that they’re smaller and less lush than mature fronds. This is normal and nothing to worry about.

Stage 3: Mature Growth

Once your Boston fern has established itself in its new pot, it will enter the mature growth stage. During this stage, you’ll notice that your fern is producing larger and more lush fronds. You may also notice that your plant is starting to produce spores on the undersides of its fronds. These spores are a sign that your plant is healthy and thriving.

Stage 4: Maintenance

Once your Boston fern reaches maturity, it’s important to maintain it properly to keep it healthy and thriving. This includes regular watering (but not overwatering), fertilizing, and pruning. It’s also important to keep an eye out for pests and diseases, which can quickly take hold if not caught early.

Tips for Caring for Your Boston Fern at Every Stage

  • Water regularly: Boston ferns like moist soil but not waterlogged soil. Water once a week or when the top inch of soil feels dry to the touch.
  • Provide high humidity: Boston ferns prefer high humidity levels. You can increase humidity by misting your plant regularly or placing a tray of water near it.
  • Use well-draining soil: Boston ferns like soil that drains well but retains moisture. A mix of peat moss, perlite, and vermiculite works well.
  • Fertilize regularly: Use a balanced fertilizer every month during the growing season (spring and summer).
  • Prune regularly: Prune dead or yellowing fronds to encourage new growth.
  • Watch for pests: Spider mites and mealybugs are common pests that can attack Boston ferns. Treat infestations promptly with insecticidal soap.
