HOW DO I WATER A TREE FERN

JANE: The trunks of tree ferns are actually a root mass, so the best technique for irrigating is to apply water up and down the trunk. Don’t make the mistake of watering into the crown of the tree fern – water tends to collect here and can cause the crown and new growth to rot out.

WHY IS MY PASSIONFRUIT FLOWERING BUT NOT FRUITING

JERRY: There are three things that could contribute to this fairly common complaint

  1. 1. Too much nitrogen – fertilisers high in nitrogen promote lush, healthy foliage growth, but will inhibit the formation of flowers and fruit
  2. 2. Add a pollen partner – Passionfruit pollination and fruit yield is increased by having more than one plant present. Passionfruits are able to recognise their own pollen, so if they receive pollen from another passionfruit, you will get more fruit.
  3. 3. Regular Irrigation – Passionfruits resent irregular watering schedules or changes to watering frequency, and will often respond to these changes by failing to set fruit. Consistent watering and moisture levels are paramount to happy, healthy, productive passionfruit.
CAN I COLLECT SEEDS FROM MY LOCAL BUSHLAND

CLARENCE: Plant materials, including seeds, can not be removed from bushland areas without a permit.  Removal of any plant materials and seeds from these spaces deprives fauna of habitat and food sources, and can seriously impact floral diversity. 

HOW SHOULD I STORE MY PUMPKIN

SOPHIE: If you grow pumpkins, you can certainly store them for longer than you may realise. Allow the pumpkin vine to die off naturally and then harvest your pumpkins, ensuring you leave at least 10cm of stalk attached to the fruit.  Only store pumpkins that aren’t damaged or injured, and store in a cool, dark place.  Ensure the pumpkins are not touching each other when stored, and check them weekly to make sure nothing has gone rotten.  Thick skinned varieties of pumpkin can be stored for around 12 months (sometimes longer) whereas the thinner-skinned varieties must be consumed earlier than that.

How to Grow and Care for Australian Tree Fern

Contrary to its name, the Australian tree fern (Cyathea cooperi, also known as Sphaeropteris cooperi) is actually more tree than fern. Typically, when we think of ferns, we envision plants such as the painted ferns (Athyrium niponicum) or autumn ferns (Dryopteris erythrosora) , which achieve a mature height of about 18 to 24 inches.

But, in its native habitat of Australia, a tree fern can grow up to 50 feet tall. This tropical plant is easily too tall for most indoor growing situations except for large conservatories and greenhouses. Still, if your space and environment allow, it can be a beautiful addition to your landscape.

Characterized by lacy, feathery fronds that grow from 10 to 20 feet in length and a hair-like, scale-covered trunk, the fast-growing, evergreen Australian tree fern can bring an exotic touch to any garden. It's best planted in the early spring and prefers warm temperatures and partial shade year-round.

Native Area Australia
Toxicity Not toxic to humans or animals

Watch Now: How to Grow and Care for an Australian Tree Fern

Australian Tree Fern Care

Australian tree ferns thrive in mid-elevation tropical environments where they can sometimes be found growing in great, prehistoric forests swathed in tepid mist. The key to growing a healthy Australian tree fern is to provide it with dappled sunlight or shade, ample humidity, and consistently moist soil. these plants are tolerant of salty winds near coastlines, but they do not tolerate salty soil conditions.

The trunk of the Australian tree fern starts out as a low, wide clump and spreads as much as six feet in a year before growing upward into a single slender trunk covered in glossy, ginger-brown hairs. The fronds are broad, bright green with triangular lacy leaves; they do not change color in the fall, and do not bear flowers or fruit. 

The Australian tree fern is one of the most commonly-seen tree ferns in the tropics, but unless you live in Australia or a similar region, you might have to go out of your way to purchase one. They're mostly grown as large, potted ornamentals in the United States and, when they are grown outdoors, are found mainly in public gardens and arboretums in tropical or semi-tropical zones. The plant has naturalized itself in Hawaii, where it's regarded as invasive due to its fast growth and prolific self-propagation via its spores.

Light

Although Australian tree ferns are shade-loving plants in general, they can also thrive in partial sun or dappled sun locations where they receive six hours of light a day. Keep in mind that the more direct sunlight the plant receives, the more likely it is that you'll need to increase your watering schedule.

Soil

Australian tree ferns can tolerate a variety of soil conditions including sand, loam, and clay. That being said, they will thrive best in a moist, loamy mixture that is rich but well-draining with a neutral to acidic pH level. It's also recommended that you add a layer of mulch around the tree, which will add more nutrients to the soil and act as a barrier to seal in moisture (particularly during very hot weather).

Water

Keep the soil moist at all times. Australian tree ferns are not drought-tolerant and need weekly watering. In extremely dry weather conditions, their need for moisture and humidity is extremely important. Avoid watering the crown directly because it can cause rot—instead, water the trunk and ensure the soil is consistently moist.

Temperature and Humidity

Australian tree ferns like a consistently warm and humid environment with temperatures ranging from 65 to 80 degrees Fahrenheit. Australian tree ferns do not acclimate well to rapid changes in humidity or temperature, which can result in browning fronds. In colder areas, you can grow the fern in a container, which gives you the flexibility to move it indoors for the fall and winter once temperatures drop too low.

Fertilizer

During the growing season, feed your Australian tree fern monthly with a liquid fertilizer. Larger specimens are heavier feeders and might require feeding every other week year-round. For the amount of fertilizer to use, follow the instructions on the fertilizer label.

Types of Australian Tree Ferns

About 1,000 different kinds of tree ferns are found in tropical or subtropical settings.

  • 'Brentwood' is a cultivar that grows faster than most tree ferns and is larger with darker green fronds than the species.
  • The New Zealand or Tasmanian tree fern is closely related, but the species is actually Dicksonia antarctica, and it tends to have a narrower crown than the Australian tree fern (but has similar requirements).

Propagating Australian Tree Fern

Australian tree fern can only be propagated from spores. You cannot propagate this tree fern vegetatively from cuttings.

  1. Collect the spores from a mature frond onto a piece of paper.
  2. In a heatproof bowl, pour boiling water over soilless potting medium to sterilize it and remove any pathogens, which can affect germination. Let the potting mix drain and cool completely before filling it into a four-inch pot.
  3. Sprinkle the spores on the potting mix and cover it with a plastic dome or bag.
  4. Place the pot in a location with a consistent temperature of around 68 degrees Fahrenheit and indirect light.
  5. Keep it moist at all times, The spores will take 2 to 6 weeks to germinate.

Potting and Repotting Australian Tree Ferns

An Australian tree fern will grow rapidly, so make sure you plant it somewhere in your landscape where it has room to grow and expand. If you're growing your tree fern in a container, repot it annually into a larger pot (with fresh soil). Because the tree fern is susceptible to root rot, make sure the container has large drainage holes. Plastic pots don't dry out as fast as clay pots so they are generally more suitable for this type of fern that needs to be kept moist at all times.

When the plant reaches the maximum size allowed by the growing space, stop repotting to slow down its growth. Eventually, it will likely outgrow both the pot and the room.

Overwintering

The Australian tree fern is a fairly hardy tree fern that can tolerate occasional low winter temperatures of 20 degrees Fahrenheit in temperature zones USDA 8 through 11. But to protect the fronds from cold damage, it is best planted in a sheltered spot such as the side of the house that is protected from strong winds.

In addition, the roots of Australian fern grown in containers can be damaged in the winter due to their lack of insulation. Winterizing the container by wrapping it with bubble wrap gives it extra protection.

Common Pests & Plant Diseases

While the Australian tree fern doesn't have any major issues with diseases or pests, it can occasionally get mites or mealybugs. The first treatment recommendation is to spray the infestation with strong streams of water; if that doesn't work, treat the plant with neem oil or an insecticide until all signs of infestation have gone.

To check if your plant is getting enough water, place your finger in the soil near the top of the soil ball, and then gently press down on the top of the soil ball. If it feels dry and hard to press down, it's time to give your fern some more water. The best way to water your fern is to use a spray bottle or spray bottle, as too much water can cause root rot and mold growth. Before pouring water, it must be thoroughly absorbed into the soil. This should be done daily until new leaves appear on the plant. After that, you can reduce the frequency of watering to once every two weeks or so. You can also use an automated system that waters your plant on its own. It's important to remember that when your fern has enough water, its leaves will begin to curl downward rather than expand upward.

Conclusion
In conclusion, one way to ensure that your tree fern stays healthy all year round is to provide it with adequate water throughout its life cycle. To do this effectively, just make sure your fern gets enough sunlight during the winter. However, if your tree fern decides not to go outside in the winter, you should provide it with enough supplemental light before spring arrives. Then, as soon as spring comes, provide the fern with light for the whole day. You can do this by placing the light directly above the fern. After all, your tree fern will be able to do without additional lighting all year round.

Do tree ferns need a lot of water?

General watering of tree ferns. If possible, water your tree fern with a cold bucket or hose every week from late spring to fall.

Can you fly over the ferns?

Over-watering causes yellowing and wilting of the leaves, which can eventually lead to root rot and fungal diseases, especially if the pot is in water. Too little water causes wilting. You can also increase the humidity around the fern by placing the pots in a pebble-lined tray.

How often do I water my tree fern?

Water generously daily or as often as possible when new leaves appear. It is important to continue watering the trunk for at least 6 months after planting.

Are potted wood ferns good?

Growing in Containers Tree ferns can be grown in containers, outdoors or in a large greenhouse or conservatory. They need bright, filtered light and moderate moisture and should be planted in Lehmericace compost with about 20% potting soil, no peat added for extra humus.

Why is my tree fern dying?

If some of the leaves of your tree fern have turned brown, this indicates that they may have been sunburned or the plant has not received enough moisture. If the area where you planted the tree ferns is too hot, you may need to move them to a more comfortable location.

Why do fern leaves turn brown?

You may see brown crowns on garden ferns if the soil gets too dry. If it seems dry, pour it slowly and deeply. Stop watering when the water runs off rather than sinking into the soil. If your fern has brown tips due to too low humidity, it's best to choose a different plant for the space.

How long do tree ferns live?

The half-life of leaves in Hawaii was six months (Durand and Goldstein, 2001a). In general, C. cooperi grows faster, has a higher photosynthesis rate, higher leaf area mass (AML), and produces more leaves than native Hawaiian ferns (Durand and Goldstein, 2001a, b).

Do you cut trees?

Leaves should be left on the plant if not dead and then cut off. Green leaves continue to produce food for the plant. Removing them before they die will reduce the amount of forage produced, resulting in shorter and fewer leaves the next season.

Should I prune dead fern leaves?

To improve their appearance, remove brown or yellow leaves from indoor ferns. Trimming those dead leaves will also improve air circulation around the plant, which will help reduce fungus or mold problems.
