Blue Star Fern Care Guide Step by Step:

Watering Requirement:

Understanding the watering needs of blue fern plants is crucial for the overall health of ferns. Blue fern loves the moist soil whether you are growing indoors or outdoors. Soil should have moisture all the time but make sure that you do not over water. Only water when you see the upper surface slightly dry. It is also important that the pot has proper drainage holes otherwise it can cause root rot.

Light Requirement of Blue Fern Plant:

Phlebodium grows successfully in bright but not direct sunlight light. If you place the fern in direct sunlight it can scorch the fronds and also disturb the health and color. Select the area where the fern receives bright and indirect sunlight. As compared to the other ferns the blue star fern has the quality to survive on low light levels this is why blue fern is most preferred and successful in indoor growing.

If you see any change in the color of the fronds then it is possible that your fern is receiving very low or very high light levels.

Best Soil for Phlebodium Aureum

Blue fern like to grow in well-draining and loose soil. Phlebodium belongs to tropical and subtropical regions so it needs consistent moisture in soil. You can choose 60 percent peat moss, 20 % perlite, and 20% orchid bark or you can adjust accordingly. Peat moss will hold the moisture, perlite will make the soil well-draining and prevent waterlogging, and orchid bark will promote aeration in the soil.

Humidity Level

Blue fern needs a high level of humidity for successful growth because it belongs to the tropical region. The minimum humidity requirement of blue star fern is 50%. You can use a humidifier to meet humidity requirements or misting can also help to maintain moisture, especially in winter when we use heaters in the house the humidity level drops. The dry and warm air in the home damages the blue fern.

In winter you can place a pot or tray of water in the room for a moisture boost. We recommend you use a humidifier rather than misting. Symptoms for low levels of humidity are brown tips of leaves.  


It is not necessary to fertilize blue fern plant but if you want to use fertilizer to support healthy growth you can use liquid balanced fertilizer with the ratio of 10-10-10. Use fertilizer after every 8 weeks in the growing season.

Do not fertilize when the blue fern is in a dormancy period which is usually from November to February. Only fertilize in the growing season. Read the instructions and dosage on the fertilizer pack properly so that you do not over-fertilize.

Pests and Diseases

The common pests and diseases that can affect are mealy bugs, spider mites, scale insects, and leaf spots. Misting can help in the initial stage to deter the pests but if pests are not controlled you can use neem oil or insecticidal soap. Overwatering be the main cause of pests and disease attack on blue fern.

Propagation of blue star fern

There are two methods by which propagation can be done.

  1. Spore propagation
  2. Division propagation

The best and easiest method to propagate is the division method. Select the mature and healthy plant that has formed a dense clump of rhizomes. Water the fern two days before division this will make the soil pliable. Carefully remove the plant from its pot without damaging its roots. Identify the rhizomes and separate them by using a sharp knife or by hand.

Plant them in separate pots and water them properly. Make sure that the soil remains moist and place the plants where they get indirect or filtered sunlight.

Common Issues of Blue Star Fern

  • Yellowing Fronds

This can be a symptom of overwatering, lack of nutrients, and direct sunlight exposure. Pests and diseases attack on the plant can also cause yellowing fronds. Firstly, only water when you feel the soil dry on touching and the pot must have drainage holes. Overwatering is normally the main cause of yellowing fronds.

Secondly, if your plant receives too much direct sunlight then you should change the place. Lack of nutrient-causing yellowing fronds is not common.

In the dormancy period, the older fronds turn into yellow color before shedding which is normal.

  • Wilting

Wilting can be a sign of several issues but the main issue that causes wilting is under watering and pest attack. Keep the soil moist to avoid wilting. Inspect the plant thoroughly if you find any pest attack take the necessary steps.
