Trunk of our Tasmanian Tree Fern has a lime green coating and is not sending out new fronds. What is it, and remedies?
Tasmanian tree ferns are generally quite hardy as long as they are in Zone 9-11; I would suggest taking a scraping from the trunk to your local extension service. This article will give you more information about tree ferns: http://www.kew.org/science-conservation/plants-fungi/dicksonia-antarctica-australian-tree-fern
How can I treat my tree ferns? Since the hard winter they have orange looking slime in the top. What can I try, if anything, to revive them?
It sounds like you have a slime mold, which is feeding of decaying parts of the plant. Clean it off and treat the plant with fungicide. Since it feeds off decaying plant matter, this means the tree fern, at the very least, has damage. If it is still alive, it may recover, but will need a careful eye on it to look for pests and disease that are prone to attack sick plants.
I have 2 Filicium decipiens (Japanese fern trees). One of them is turning yellow while the other is beautiful and green. What's wrong? What do I do to save my tree?
Chlorosis (yellowing) is common in these plants and is often the result of an iron deficiency, but may be attributed to unseasonably cooler temps as well. Here is more information: https://www.gardeningknowhow.com/plant-problems/environmental/leaf-chlorosis-and-iron.htm
We have like a fern in our garden but it grows like a tree. This plant is from the garden next door - from the root. It's a real problem. The more I cut it and a drop of rain and sun hits, it's up a foot in height. We just keep cutting but does no good at all. The leaves are pretty big and they unfold.
The neighbors plant or tree must be sending out runners that have decided to pop out in your yard.
You can trim back the invasive plant and dab the cut stem with a herbicide. Do this carefully so that it does not kill anything else in your yard.
How high can Australian fern trees grow?
According to my research, they can grow up to 49 feet high. For more information, please visit the following link:
What type of compost should I use for a Tree Fern, please? Standard ericaeous or is there a specific type?
Most types of compost are just fine, a loamy-based ericaceous compost is great.
Hi My problem is with our very healthy treeferns. We live in Olinda in the Dandenong Ranges and the parrots love to break off the fronds from the treeferns making them look terrible! Mainly they break them half way down the frond. Each winter they destroy the ten healthy thick ferns, making them thin and sparse for summer. This has happened for the past two winters. I am sure they are nesting but I dont see any nests in the middle of the treeferns and they dont carry off the broken off fronds as they are all on the ground. Is there something I can do to discourage these birds from doing this? Thanks.
My research shows netting the plants is the most recommended.
Other ideas are balloons and even hang old cd's from the plants.
