Dicksonia antarctica - Tasmanian tree fern

The Tasmanian tree fern is a beautiful plant that, with its unique shape, transforms any room or garden into a piece of paradise.
In this article we will explain almost everything about the care of the Tasmanian tree fern.
Where to best place and water the Tasmanian tree fern, and of course all other useful information about the Tasmanian tree fern.

The is a fern from the genus Dicksonia, which grows up to 15 meters high. It is a real jungle plant. It grows a soft stem that very easily releases particles when you pull it. This is also the way it sprays its seeds through the jungle.

It gets long graceful fern branches that roll out from the core of the trunk. It grows these leaves very quickly. Within a few weeks, 5 or more branches longer than a meter can emerge from the core.

The Dicksonia antarctica - Tasmanian tree fern likes a drink of water

For almost all plants, watering is an important part of the plant's survival and growth. The Tasmanian tree fern is certainly no exception! In this chapter, you will find all the necessary information so that you can provide your Tasmanian tree fern with moisture in the right way.

Summer

During the summer it is very important that this plant, when it is outside, is kept well moist. Especially during the warm days it should be watered every day, so that both the root ball and the trunk are well moist. During the less warm days this can sometimes be skipped for a few days. This is so important because otherwise the plant 'drinks' moisture from its leaves, causing it to become dry and eventually die. This should of course be prevented.

Winter

When winter is upon us, the rules are reversed! If the Tasmanian tree fern is outside, it must remain dry so that the moisture does not freeze and damage the plant. The Tasmanian tree fern does not suffer from a dry root ball during this period, it is in a kind of hibernation!
When the plant is kept indoors during the winter it should be kept slightly moist, so not soaking wet (as in summer), but just so that the root ball feels slightly damp.

General rules

In addition to the above guidelines, it is best to follow these rules:

First, give the plant a little water. If the soil is dry within 2 days, it means it needs a little more water. Adjust the amount of water until it still feels slightly moist between 2 and 5 days after watering, and almost dry after 5 days. If it feels very wet after 5 days, wait until it is almost dry and water again, but reduce the amount.

If it has just rained, the tree fern does not need extra moisture, but if it has been dry for a few days, it is high time to water it. So make sure to moisten it regularly, but it does not have to be every day.

Spraying

The Dicksonia has a special requirement of water, namely that the water is poured into the core as well as sprayed over the trunk. And if it is good, some of the water flows to the root ball.

Where is the best place to plant the Dicksonia antarctica - Tasmanian tree fern?

For many plants it is important to determine the right place where it can stand best. A lot or little sun, sheltered from the wind, in the shade at certain sun positions… all this makes a difference for the development of the plant. In this chapter you will find what is best for the - Tasmanian tree fern.

Light

The Tasmanian tree fern is a plant that likes a fair amount of sunlight. It likes to be in full sun or half shade, taking in all the light. Is it indoors? Then it wants a spot near a window or where there is some light. The Tasmanian tree fern requires at least 1 to 3 hours of direct sunlight per day

Wind

Make sure that the Tasmanian tree fern experiences as little wind as possible. Wind can damage the leaves, causing them to die off more quickly. A little wind is not a problem.

Temperature requirements

Minimum temperature during the day: -10 ℃
At night minimum -5 ℃

Repotting, why and when?

Repotting a Tasmanian tree fern whose root ball has grown through has a few advantages. Namely, the plant grows faster when the roots have the space. The plant can also withstand lower temperatures better with a larger root ball. It can then absorb moisture from the soil better and is therefore stronger and more stable.

General rules

When the Tasmanian tree fern has rooted (often every 2-3 years) we recommend repotting it in the spring. If it is always inside, it does not matter. If it is outside, it is not a problem to repot it in the summer, but we advise against it in the autumn and winter, because it will not grow and root optimally then. This can make it somewhat weak, and possibly suffer damage from frost.

When you choose to repot your Tasmanian tree fern, choose a nice pot that is twice the size of the root ball. Place a layer of hydro grains at the bottom of the new pot, for better moisture control. It will thank you for that. Fill this layer with some Mediterranean potting soil. This type of soil ensures that the Tasmanian tree fern roots optimally and is fed. Then you can place the root ball on the ground. Make sure that the top of the root ball is slightly below the edge of the pot. Aim for a difference of 2 to 6 cm. This difference ensures that the water does not run off the root ball when you water it.
Every year you should replace the top layer of soil, because it hardens and 'wears out' in nutrients, due to regular watering and because of the sunlight on the upper edge of the root ball.

Provide the Dicksonia antarctica - Tasmanian tree fern with good nutrition

During the summer and spring periods your Tasmanian tree fern needs to be fed well. Unfortunately, a good soil type is not enough for this. It certainly helps in certain needs of the plant. But to keep the leaves nice and deep green and strong, we recommend supplementing the nutrition with the specialized food [florentus]. Pokon is often recommended by other shops, but we advise against it, because .... Florentus is a product based on natural nutrients from many different sources, a mix of organic, vegetable acids and pure concentrates. It is the perfect 'fertilizer' for plants. Your plant is very grateful for this nutrition and will reward you with shiny deep green leaves and healthy strong roots.
If you want to give your plant that little bit of extra luxury, we also recommend supplementing florentus with [Plant Ultra]. This provides a few extra useful nutrients that the Tasmanian tree fern loves. They are not essential, but do help with root growth and extra health and strength of the palm.

When the leaves change color

The leaves can get black leaf tips. This can mean that too much water has been released. Brown or yellow leaves can mean that too little water is being released. We then recommend checking this and possibly adjusting the watering. We also recommend making the plant a bit more beautiful by simply cutting off the ugly tips with scissors.

It is also possible that the Tasmanian tree fern has been moved from a place with a lot/little light to a place with a different amount of light. This can also cause the leaves to discolour. The new leaves will be more resistant to direct sunlight.

How and when to prune the Dicksonia antarctica - Tasmanian tree fern?

The leaves of the Tasmanian tree fern will eventually wither. If this is the case with a leaf, you can simply cut the stem close to the trunk. It is not a big deal to cut off an entire leaf with the stem of the plant. This is the way the plant forms its trunk.

How can I propagate the Dicksonia antarctica - Tasmanian Tree Fern?

Many plants are easy to propagate by e.g. cuttings or harvesting and planting the seeds. The Tasmanian tree fern only propagates by seed.
