Do Boston ferns need big pots?

Answered by Jason Smith

When it comes to potting and repotting Boston ferns, one of the key considerations is the size of the pot. Boston ferns generally prefer to be slightly pot-bound, meaning they like their roots to be snug in the pot. However, as the plant grows, it will eventually outgrow its current pot and need to be repotted into a larger one.

In terms of selecting a pot size for your Boston fern, it’s generally recommended to choose a pot that is slightly larger than the plant’s root ball. This allows for some room for the roots to spread out and grow, while still maintaining a somewhat snug fit. A good rule of thumb is to size up your pot by about 2 inches in diameter.

For example, if your Boston fern has a root ball that measures 6 inches in diameter, you could choose a pot that is approximately 8 inches in diameter. This will give the roots some additional space to grow without overwhelming the plant.

It’s worth noting that Boston ferns have shallow root systems, so depth is not as important as the overall width of the pot. As long as the pot is wide enough to accommodate the root ball and allow for some growth, your Boston fern should be happy.

When it comes time to repot your Boston fern, there are a few steps you can follow to ensure a successful transition. First, gently remove the plant from its current pot, being careful not to damage the delicate fronds. Gently loosen the roots and remove any dead or rotting material.

Next, place a layer of fresh potting soil in the bottom of the new pot. This will provide a nutrient-rich base for the fern to grow in. Position the fern in the center of the pot, making sure the root ball is level with the top of the pot.

Fill in around the roots with additional potting soil, gently pressing it down to eliminate any air pockets. Be careful not to bury the crown of the plant, as this can lead to rot. Water the newly potted fern thoroughly, allowing any excess water to drain out of the bottom of the pot.

After repotting, it’s important to keep a close eye on your Boston fern and monitor its moisture levels. The larger pot size may mean that the soil takes longer to dry out, so be mindful not to overwater. Boston ferns prefer consistently moist soil, but they don’t like to sit in waterlogged conditions.

While Boston ferns prefer to be slightly pot-bound, they will eventually need to be repotted into a larger pot as they grow. When selecting a pot size, choose one that is slightly larger than the plant’s root ball, or size up by about 2 inches in diameter. Follow proper repotting techniques to ensure a successful transition for your Boston fern.
