Though this lush palm prefers dryer soil, it loves humidity. Unless you live in a balmy climate, it is best to place a humidity gauge in the same room as your plant. Most often, the fishtail palm tree is used as an indoor plant where the air tends to be dry. The minimum humidity needed for this divine plant is 50%. If it drops any lower, consider using a cool-mist room humidifier or a humidity tray to help maintain a proper balance.

The Caryota mitis needs warm to average temperatures ranging between 65 degrees and 85 degrees. They do not tolerate cold very well and should never be placed near or under a vent. Make sure to use a high-quality potting mix with sand added in to allow water to drain from the pot quickly.

A ratio of 3 to 1 of potting mix and horticultural sand will ensure the right level of water drainage. Never use beach sand because the salt in the sand is harmful to palm trees.

Propagating Fishtail Palm Trees

Being that this is a tree, it can’t be propagated from cuttings like other types of house plants. The fishtail palm tree is grown from seeds that should be planted in the spring or summer season.

Make sure to only plant them just under the soil as opposed to deeply burying them. Fishtail palm tree seeds germinate best when only lightly covered and kept in a moist, warm, fresh potting mix.

To boost efficiency, use a seedling heat mat to keep a steady temperature of about 70 degrees. Once the seeds sprout, you are on your way to new plants. When you are ready to propagate the fishtail palm tree after they sprout, all you have to do is divide the stems that rise from the clumps at the base of the offsets.

After gently separating the clumps, pot the offsets in individual pots. Feed the trees once yearly at the start of summer with a palm specific slow-release fertilizer.

The palm with grow best in a peat-based soil, or you can use a coir-based potting mix with added material. This material will ensure that the plant drains properly and doesn’t develop soggy roots.
