What should I do if I water my Australian tree fern too much or too little?
Overwatered Australian tree fern
Despite how much it loves water, it is possible to overwater the Australian tree fern. This is most likely to happen if you leave your plant sitting in a pool of water or use a planter that doesn’t have drainage holes. Either of those conditions will be too wet and will prevent the roots from being able to take up nutrients and moisture. Too much moisture in the soil can also allow fungal or bacterial diseases to develop.
Wilted and yellow leaves are the initial symptoms of overwatering. Over time, the stems may droop and fall over, or begin to feel soft and mushy. However, be sure to check for other causes if you suspect your Australian tree fern is overwatered, since other issues can look similar and it’s difficult to give this plant too much water.
Underwatered Australian tree fern
Vigilance is required to keep this plant wet enough, unless you’re using a self-watering planter, meaning that many fern owners inadvertently let their plant get too dry now and then. In dry conditions, this plant can change in appearance seemingly overnight, from lush and green to brown and crispy.
In extreme cases, the plant may dry up so thoroughly that it seems there are no living fronds left. But it may still be possible to save the plant if some of the roots are still healthy. Cut off all of the dry and dead stems, then water thoroughly and return the plant to its usual location. Unless the roots are all dead, this plant can be surprisingly resilient and start putting out new fronds. It may take several months to grow back to the size it was before, but this is possible if you provide proper care in that time.

How can I water my Australian tree fern properly?
Your Australian tree fern prefers consistently moist soil that mimics its native enironment, which could mean watering as often as every one or two days. This is a plant that should not be allowed to dry out. Once the top layer of soil begins to feel even slightly dry, it’s time to water again. And don’t just give it a few drops of water: soak the soil completely until water drains out from the bottom of the pot. After the excess water has drained out, dump it so the pot isn’t sitting in a puddle. This is the best method to ensure that soil never gets too dry.

What should I consider when watering my Australian tree fern?
The amount of humidity in the air around your Australian tree fern will influence how often you need to water it. Higher humidity in the air means less frequent watering, as evaporation is slower. Keeping this plant near a heating or cooling vent will cause it to dry out quickly, so choose a location that is protected from any type of draft. They prefer dappled and indirect sunlight and temperatures between 55-80 degrees F (13-27 degrees C) meaning that keeping these ferns in a warm and sunny spot windowsill could cause them to get dehydrated quickly.
Rainwater or distilled water is great for this plant if you have access to it, although tap water in most places also works fine. Certain minerals and chemicals in tap water can cause brown leaf tips, especially since Australian tree fern has very thin and delicate leaves.
Small pots can cause issues for Australian tree fern , because they only hold a small amount of potting medium and can dry out more quickly. It is best to allow this plant more space in the pot than many other houseplants.
Consider using a self-watering planter for Australian tree fern. This type of pot uses a wicking system that allows the soil to continuously soak up water from a central reservoir, meaning that the moisture level in the soil stays consistently moist. Not only does this type of pot keep you from having to constantly water your fern, but it is also quite beneficial for the roots to have a constant supply of water instead of going from dry to wet and then back again.

Name story

Australian tree fern
The genus name of the Dicksonia antarctica honors British botanist James Dickson (1738-1822); the species epithet likely refers to the fact that the plant is found in the southern hemisphere, closer to the south pole. The australian tree fern is also sometimes called 'soft tree fern’ because the trunk is covered in soft-looking, fibrous hairs.

Trivia and Interesting Facts

The ‘trunk’ of this tree fern is actually the decaying remains of earlier frond growth; it can grow up to nearly 15 m tall, but more commonly reaches heights of 1.8 to 6 m. It has earned the Royal Horticultural Society's Award of Garden Merit.

Indoor plants require adequate lighting for optimal growth. When natural sunlight is insufficient, particularly in winter or in less sunny spaces, artificial lights offer a vital solution, promoting faster, healthier growth.
1. Choose the right type of artificial light: LED lights are a popular choice for indoor plant lighting because they can be customized to provide the specific wavelengths of light that your plants need.
Full sun plants need 30-50W/sq ft of artificial light, partial sun plants need 20-30W/sq ft, and full shade plants need 10-20W/sq ft.
2. Determine the appropriate distance: Place the light source 12-36 inches above the plant to mimic natural sunlight.
3. Determine the duration: Mimic the length of natural daylight hours for your plant species. most plants need 8-12 hours of light per day.
Important Symptoms
Symptoms of Insufficient Light in %s
Australian tree fern thrives in shady environments and can tolerate low light. Although symptoms of light deficiency may not be readily apparent, it's important to provide adequate light to ensure optimal growth and health.
View more
(Symptom details and solutions)
Small leaves
New leaves may grow smaller in size compared to the previous ones once they have matured.
Leggy or sparse growth
The spaces between leaves or stems of your Australian tree fern may become longer, resulting in a thin and stretched-out appearance. This can make the plant look sparse and weak, and it may easily break or lean due to its own weight.
Faster leaf drop
When plants are exposed to low light conditions, they tend to shed older leaves early to conserve resources. Within a limited time, these resources can be utilized to grow new leaves until the plant's energy reserves are depleted.
Slower or no new growth
Australian tree fern enters a survival mode when light conditions are poor, which leads to a halt in leaf production. As a result, the plant's growth becomes delayed or stops altogether.
Lighter-colored new leaves
Insufficient sunlight can cause leaves to develop irregular color patterns or appear pale. This indicates a lack of chlorophyll and essential nutrients.
Solutions
1. To optimize plant growth, shift them to increasingly sunnier spots each week until they receive 3-6 hours of direct sunlight daily, enabling gradual adaptation to changing light conditions.2. To provide additional light for your plant, consider using artificial light if it's large or not easily movable. Keep a desk or ceiling lamp on for at least 8 hours daily, or invest in professional plant grow lights for ample light.
Symptoms of Excessive light in %s
Australian tree fern prefers shade and is sensitive to direct sunlight. Due to their intolerance to sun exposure, they easily develop symptoms of sunburn, making proper shading essential for their well-being.
View more
(Symptom details and solutions)
Chlorosis
Chlorosis is a condition where the plant's leaves lose their green color and turn yellow. This is due to the breakdown of chlorophyll from excessive sunlight, which negatively affects the plant's ability to photosynthesize.
Sunscald
Sunscald occurs when the plant's leaves or stems are damaged by intense sunlight exposure. It appears as pale, bleached, or necrotic areas on the plant tissue and can reduce the plant's overall health.
Leaf Curling
Leaf curling is a symptom where leaves curl or twist under extreme sunlight conditions. This is a defense mechanism used by the plant to reduce its surface area exposed to sunlight, minimizing water loss and damage.
Wilting
Wilting occurs when a plant loses turgor pressure and its leaves and stems begin to droop. Overexposure to sunlight can cause wilting by increasing the plant's water loss through transpiration, making it difficult for the plant to maintain adequate hydration.
Leaf Scorching
Leaf scorching is a symptom characterized by the appearance of brown, dry, and crispy edges or patches on leaves due to excessive sunlight. This can lead to a reduction in photosynthetic capacity and overall plant health.
Solutions
1. Move your plant to the optimal position where it can receive abundant sunlight but also have some shade. An east-facing window is an ideal choice as the morning sunlight is gentler. This way, your plant can enjoy ample sunlight while reducing the risk of sunburn.2. It is recommended to trim off any completely dehydrated or withered parts of the plant.

Essentials
Australian tree fern is originally found in a temperate environment, where temperatures range from 59 to 95 °F (15 to 35 ℃). It thrives in these conditions and may require seasonal adjustments if kept in cooler or warmer climates.
Regional wintering strategies
Australian tree fern has strong cold resistance, so special frost protection measures are usually not necessary during winter. However, if the winter temperatures are expected to drop below {Limit_growth_temperature}, it is still important to provide cold protection. This can be achieved by covering the plant with materials such as soil or straw. Before the first freeze in autumn, it is recommended to water the plant abundantly, ensuring the soil remains moist and enters a frozen state. This helps prevent drought and water scarcity for the plant during winter and early spring.
Important Symptoms
Symptoms of Low Temperature in Australian tree fern
Australian tree fern is cold-tolerant and thrives best when the temperature is above {Suitable_growth_temperature_min}. During winter, it should be kept above {Tolerable_growing_temperature_min}. When the temperature falls below {Limit_growth_temperature}, although there may not be any noticeable changes during winter, there may be a decrease in sprouting or even no sprouting during springtime.
Solutions
In spring, remove any parts that have failed to sprout.
Symptoms of High Temperature in Australian tree fern
During summer, Australian tree fern should be kept below {Suitable_growth_temperature_max}. When the temperature exceeds {Tolerable_growing_temperature_max}, the leaves of the plant may become lighter in color, prone to curling, and more susceptible to sunburn.
Solutions
Trim away the sunburned and dried-up parts. Move the plant to a location that provides shade from the midday and afternoon sun, or use a shade cloth to create shade. Water the plant in the morning and evening to keep the soil moist.
