Blue Star Fern Care Guide and Plant Profile

The Blue Star Fern, Phlebodium aureum, is a unique plant in the fern family. Its ability to survive in lower light with less humidity makes it a great houseplant candidate.

This fern often grows on the sides of trees in the South American rainforests. This plant has long curly thick fronds that are blue green in color.

This fern is not as finicky as many of the ferns you will find. It can handle lower light and does not need excessive amounts of humidity.

This is a simple plant to care for. However, there are a few common problems that people often run into with these plants.

Browning, black, or purple leaves can often be caused by excess water sitting in the crown of the plant. Because they are sensitive to getting their leaves and crown wet, make sure you water just the soil and not the foliage of the plant. Bottom watering is a great way to water this plant.

Browning tips is often caused by infrequent watering schedules or a lack of water. Keep your fern on a regular watering schedule to avoid brown tipped leaves.

  1. Blue star ferns prefer well draining soil. The roots will rot quickly if they sit in moist soil.
  2. A mix of potting mix, orchid bark, and perlite will keep the roots happiest.
  3. Make sure your pot has drainage at the bottom. Do not use a pot with no drainage hole for this plant.
  4. A heavy soil potting mix is not recommended for Blue Star Fern plants.

Pot Size and Type:

  1. The blue star fern plant can grow in many different kinds of pots, I like to plant mine in ceramic pots with a drainage hole.

  1. Water your blue star fern plant when the soil is dry at least an inch down. Ferns prefer a moist soil. This plant may drop leaves if it dries out too much
  2. Watering is best done on a regular schedule so the plant is not over or under watered. Both can cause stress on the plant.
  3. The recommendation for watering is every 1-2 weeks.
  4. In dormant winter months reduce watering to when the soil is dry.
  5. Never let this plant get wet feet. heavy wet soils encourage root rot and fungus gnats.

  5. To minimize the possibility of pests be sure to check all nursery plants before bringing them home.
  6. Quarantine all new plants until you are sure no pests live in them.

How to Propagate:

Rhizome Division:

The easiest way to propagate a mature blue star fer plant is to divide it when it is time for a repotting.

  1. Gently un-pot your mature blue star fern.
  2. You will see separations of the stems into groups growing out of bulb shaped rhizomes.
  3. Gently separate the rhizomes and attached roots from the mother plant. You may have to cut the roots if they are deeply entangled but try not to. Rather gently work the roots away from each other until the rhizomes are separated.propagating zz plant-succulent soil mix
  4. Repot both the new division and the mother plant.
  5. As you will see in the video there may be several rhizomes growing together in your plant.
  6. You can divide the plant into as many small plants as you wish and repot them into several pots.
