How to check the soil of Boston fern
How does the soil feel on the surface?
Touch the soil surface. This plant must never dry out.
- Dry: the surface feels dry and light. Water the plant.
- Damp: the surface feels cool and a little moist. Do not water yet.
- Wet: the surface is soggy, or you see water. Do not water. Check the drainage.
Do not water on a fixed day. Test the soil first. Read the soil check guide.
Soil mix
Use a rich potting soil with peat or coir. Add perlite so the water drains.
Tips for Boston fern
- Fronds that dry and drop mean dry air or dry soil. Water sooner and raise the humidity.
- Keep the plant away from heaters and cold drafts.
- Pale fronds mean too much sun. Move the plant out of direct light.
