A native of Australia, the Kimberly queen fern boasts majestic sword-shaped fronds that make it an excellent houseplant. This lush evergreen plant tends to grow quite densely and rapidly. It’s suitable for growing either indoors or outdoors as long as you can meet its needs. Similar to other types of fern, the Kimberly queen species requires adequate levels of humidity and soil moisture. It’s not exactly a low-maintenance plant but it’s worth considering for household environments due to the graceful beauty of its foliage.

The vibrant green fronds of this fern provide a tropical touch to any outdoor living area. For this reason, the Kimberly queen fern is often grown in a container to decorate the patio. It can look great by itself as a specimen plant but it’s also recommended in larger arrangements together with other shade-loving plants. If you’re interested in growing the Kimberly queen fern, check out the essential care requirements of the plant.

1. Light

Medium light with sufficient humidity is ideal for the Kimberly queen fern. It’s recommended to plant it outside only if you live in USDA hardiness zones 9 to 11. Select an appropriate spot in the garden where the plant can enjoy good afternoon shade. It’s recommended to keep ferns under tall trees because their canopy gives excellent sunlight protection.




Considering the delicate nature of the green fronds, it’s just as important to protect the plant from direct sunlight indoors as it is outdoors. Try to find a place in your house where the fern can take advantage of sufficient indirect light.

2. Water

Consistent levels of moisture are essential to allow the Kimberly queen fern to flourish. The plant needs regular watering to prevent the soil from drying completely and leave the roots unable to absorb moisture. It’s particularly important to maintain watering consistency when the plant is still in its initial growth stages.




Once fully established, the Kimberly queen fern’s root system becomes strong enough to withstand more difficult growing conditions. Be careful not to overwater this plant because it can die if it becomes waterlogged. Keep in mind other life-supporting factors such as light and temperature and adjust the watering routine accordingly to make sure the soil stays adequately moist.

3. Soil

Soil Requirements Kimberly Queen Fern

Soil reinforced with peat, perlite, or compost can be more beneficial to Kimberly queen ferns compared to standard potting mixes. This is due to the importance of features such as proper drainage and reliable moisture retention. Considering the natural environment of this plant – the forest floor – it’s recommended to opt for rich soils that can hold a balanced amount of water to allow the fern to thrive.



4. Temperature

The optimal temperature range for this type of fern is somewhere between 60 to 75 degrees Fahrenheit. It can sit comfortably in most indoor environments. Low winter temperatures are not easily tolerated by the fern and it won’t survive frost. This is why the plant should be brought indoors in colder climates during the winter season.

5. Humidity

Whereas other plants can manage just fine in multiple humidity conditions, the Kimberly queen fern is more strict because it requires high humidity. The lush color and pleasant texture qualities of the fronds will be severely affected by dry air. Therefore, it’s critical to maintain adequate levels of humidity.




Indoor ferns are kept healthy with the help of a humidifier while avoiding places close to drafts both cold and hot. Check out this compact humidifier on Amazon that works great for indoor plants. Another solution for increasing humidity is using a water tray that surrounds the plant. Don’t keep the fern close to heaters or fireplaces.

6. Fertilizer

Regular fertilization can help the development of the fern’s dense foliage. It’s mostly important to use a balanced fertilizer during periods of active growth. Consider using a water-soluble fertilizer for both container-grown ferns as well as plants that grow directly in the ground. Too much fertilizer can be damaging, especially when used in the colder times of the year.

7. Propagation

Propagation for Kimberly Queen Fern

Plant division is the simplest method to use for propagating the Kimberly queen fern. You will need to separate the root ball into more pieces that can be then planted individually. Place the divided clusters in their own pots with the same type of soil mix. Eliminate air pockets in the soil and water regularly to encourage new growth.




Shaded places work best for successful propagations. You will also need to keep the planted clusters extra-warm in the initial developmental stages. This can be achieved with the help of a plastic bag cover that simulates a greenhouse environment and accelerates growth.

8. Pruning

Kimberly queen ferns are fairly low-maintenance when it comes to pruning. The green fronds will naturally grow in an elegant shape so pruning isn’t necessary. Houseplants in the spring can be trimmed to remove dead or diseased foliage that appeared in the winter. Make sure the pruning shears are sterilized with rubbing alcohol after each cut.

9. Potting

When selecting a suitable pot for your Kimberly queen fern, try to avoid very large models. All that excess soil can retain too much moisture even if the pot features good drainage holes. This might lead to serious root problems such as rotting. Take into account the size of the fern’s root ball when deciding on a fitting pot. Add small pebbles to the bottom of the pot for more efficient moisture drainage.

10. Common Problems

As long as you meet the growing requirements of this fern, it’s very unlikely for it to be affected by many diseases or pests. Root rot is the only dangerous problem that appears when you overwater the plant. Kimberly queen ferns grown outdoors aren’t particularly susceptible to pests. Indoor plants tend to be more affected by common damaging insects such as mealybugs or spider mites. Infestations are best treated with reliable remedies such as Neem oil spray or insecticidal soap.
