Caring Tips for Austral Gem Fern

The difficulty level of caring for these plants is quite low, but ensure that all the basic necessities are provided to the plant for healthy and strong growth. We have provided you with the 6 basic requirements that must be fulfilled for your Gem fern ideal growth.


Water requirements for this plant are low, as they can thrive under dry conditions well. We recommend you water the plant only if the upper layer of the soil feels dry.

Please make sure that you do not overwater the plant, as water staying in the soil for too long can leave the plant susceptible to diseases. The size of the pot, lighting, and temperature should also be kept under consideration before watering your plant.

If the temperatures are high and the lighting is bright, you should water it more often, but make sure that you do not leave the plant soaking in water.


These plants prefer a well-drained potting mix, but they can also flourish in a commercial potting mix too. Make sure that the soil you use has PH below 7, as Austral gem Ferns love to grow in rich, acidic soil.


Austral gem ferns require medium to bright lighting conditions but do not place them directly under the open sun. These plants can live under low light conditions, but their growth will be negatively affected.

We recommend you place them under a window where indirect bright sunlight reaches the plant.


Average home temperature between 60 to 80 degrees Fahrenheit is ideal for these plants to grow well; however, keeping them in an environment too cold can cause the leaves of the plant to wilt and die in no time.


Use fertilizer once a month between April and September. We advise you to use a good quality houseplant fertilizer of half strength to boost the growth in the growing season.

Please do not feed the plant in the winter season as the plant becomes inactive, and fertilizer would only negatively affect your plant. Too much feeding can cause the tips of the leaves to turn brown.


A 50 to 60 percent humidity level is commonly seen in most of our houses, which is acceptable for the plant as it can thrive in such conditions. Make sure that you keep the soil and the air around the plant moist.
