Grow healthy ferns: understand their characteristics and needs
Nephrolepis exaltata, known as the Boston fern, is native to tropical and subtropical regions. It is characterized by its long, arching, and dense, deep green fronds.

To thrive, the fern requires indirect ambient light, constant humidity and temperate temperatures, imitating the conditions of the tropical forests from which it originates.
Common watering mistakes: excess, deficiency, and their consequences
One of the most common problems in Boston fern care is improper watering. Both excess and lack of water can cause irreparable damage.:
- Excess irrigation: This usually causes leaves to turn yellow or soft, the plant to look weak, and the roots to rot. The substrate remains soggy and may even smell unpleasant.
- Lack of irrigation: The tips and edges of the fronds become dry or brown, and the plant loses turgidity or volume.
To EVITED these problems, Water only when the surface layer of the substrate is dry to the touch and never leave water standing in the saucer under the pot. Use water at room temperature and preferably chlorine-free. Remember that the plant needs less water in winter.
Environmental humidity: the key to success and its most common mistakes
To increase ambient humidity:
- Spray the fronds with lime-free water every 2-3 days, especially during dry seasons or with heating/air conditioning.
- Group several plants together to create a humid microclimate around it.
- Place the pot on a tray with pebbles and water (without the bottom directly touching the water).
- Use a room humidifier if the environment is very dry.
Excess humidity is also a problemIf you see water droplets on the leaves, fungus, or a bad smell, ventilate the space better and avoid spraying if the environment is already very humid.
Lighting: Common Mistakes and How to Fix Them
