Best Container Size for Boston Fern
If you have brought the plant from a nursery, transfer it to a container that’s one size bigger than the old one. While re-potting, use a pot that’s a size bigger than the root ball of the plant. Make sure the container has a drainage hole at the bottom.
Requirements For Growing Boston Fern
This gorgeous fern favors bright, indirect light—avoid placing the plant in too much shade as it can make the fronds dull and sparse. Also, an excessive amount of sunlight can bake the fronds.
Note: Ensure you are not growing the plant in direct sunlight.
The plant does best in rich,well-draining, and loamy soil. While growing in containers, use peat-based potting mix. You can also make your own growing media with the help of our article here.
Keep the soil slightly moist but do not overwater the plant. Dry soil can make the fronds dry, and they will drop off. The best method to follow is to keep an eye on the topsoil—when it feels dry to touch, water the plant till it comes out of the drainage hole of the pot.
When the plant is in dormancy during the fall and winter months, reduce the watering.
This fern likes mild temperatures ranging between 60-75 F (15– 24 C ). The plant cannot withstand extreme heat or cold. Avoid exposing the plant below 50 F (10 C).
Boston fern prefers humidity levels above 70-80 percent. You can boost the humidity by keeping the pot on a tray filled with pebbles and water. Mist the plant regularly.
Boston Fern Care
If you have used a high-quality and rich potting mix, then you don’t have to fertilize the plant for the first 3-4 months. Post that, use balanced liquid fertilizer, diluted to a half-strength, once every 6 to 10 weeks (frequency depends on the growing condition).
Avoid feeding in the late fall and winter months.
When roots are oozing out of the soil, then it’s time to re-pot. One more sign is stunted growth. Start repotting during spring—go for one size bigger pot than the old one. Also, use a fresh potting mix.
Pests and Diseases
Keep a close eye on scales, mealybugs, and aphids. They can be handpicked or taken care of by using a neem oil solution or an insecticidal soap. To keep most of the diseases at bay, make sure that you are never overwatering the plant.
