Help, is my tree fern dead

13 years ago

I purchased a dicksonia tree fern last year and planted it amongst my fern garden - this is a shaded area and only gets the last of the late afternoon sun for a very short period of time. I took some advice regarding what to do with my fern over the cold period and it may perhaps have been the wrong advice. I cut the frons and then covered the trunk to protect it from the frost & snow. Unfortunately there seems to be no sign of new frons - have I killed my fern or should I be patient in the hope that they will eventually appear?

I would appreciate some guidance regarding our 5-6 feet Dicksonia Antartica which we feared had died over the last, very mild, winter. Every year it has been protected with straw and fleece and has survived some very harsh winters. Ironically when uncovered this year whilst I could see the silky brown hairs no fronds appeared and around June time we decided that Gary, as he was known, was no longer living.

He was given a new role in the garden as host to some solar lights however much to our surprise, in late July, a frond appeared. He now has four or five very weak fronds; the longest is only around nine inches. When purchased some eight years ago his fronds were magnificent but over the years they have deteriorated in thickness and length. I believe this to be as a result of him being kept in full light over that period. I have now moved him to a more sheltered position and I plan to provide some shading before next summer.

Should I treat him as in previous years, covering him from November to April? Can I ever expect Gary to regain his looks or will small fronds be the norm?

Would appreciate any advice regarding this. Many thanks in advance.

Do you have anywhere warmer? Perhaps with more sun? Tree ferns are often left fully exposed on sunny hillsides after logging and do just fine, even after being battered by logging equipment. Or along roadsides. They're pretty resilient, normally.

The main part that needs protection is the crown, which is where the new fronds/fiddleheads begin. You'll know it's still alive when you see bumps covered in silky brown 'hair' coming from the crown. In at least one species they may also come from the trunk. Now that summer has tentatively begun just keep an eye on the plant. It could well respond to the warmer weather.

I'm wondering about cutting back the fronds for winter. D fibrosa usually has old dead fronds hanging over the trunk to provide protection from various hazards (not least of which are stray seeds which start growing on the trunk.) If they were left on and bubble wrap added. If the previous season's fronds were tied together at the top, like you do with cauliflowers, then there would be something to start the season with, perhaps.

They're evergreen. Fronds die off, maybe several if there's a drought running, but they don't usually drop the lot. They can come back after fire or being stripped by equipment. They can stand being the only stems left upright - although they clearly do better with more shelter and humidity. When they're tall enough to have a trunk then the crown shows above the surrounding bush, particulary in regenerating cutover or a revegetating area after weather events have caused slips. Fairly tough.

While it's little - could you make it a shelter as you would for establishing a lemon tree? Something sturdy enough to take the weight of any snow, or strong winds. Wrapped with sacking/hessian, or fleece. With horticultural plastic and fleece over the top. Then it could keep its fronds.

ive have had my tree fern for several years now and it appears to have suffered through the winter period, instead of being its usual silky brown hair in the centre ther appears to be a deep layer of smelly mould, I have tried to scrape the mould away but it soon re appears. i was wondering if by cutting off the top part of the tree would help??? I`m devastated that this has happened to one of my special plants as I did cover and protect it through the winter months. Please help regards Caroline.

I really feel sorry for you, and I know that it isn't always possible to be there when a tree company schedules their appointments so you can intervene if necessary and it's possible that wouldn't be appreciated anyway. Also, companies like that doing the same job to two different customers may have one complain enough wasn't taken off and the next say too much. It has to be spelled out even if that takes drawing diagrams, and not left to their discretion. How they prune and trim (assuming they knew what they were doing) may vary with the desired outcome. It has only been rather recently that a tree care company has even been available with any type of certification in our area. We used one, and I got the impression that the only employee we saw who had a grip on the tree situation was the one who came to give us the initial estimate who then gave directions to the crew and, who were not nearly as experienced. IOW the promise and the delivery were two different things. Happens with a lot of trades, like when I had a g'house wired and had to stop a couple of apprentices mid-stream because they were clueless and the only crew on the job. We are on our third tree company now and it's a good fit. We have major trees here and it's an on-going issue to keep them in good order or suffer the consequences. I don't trust a new one until they've done minor work and I can see them in action. The owner of the one we use is here through the whole job and he is a good balance of experience, training and reasonable cost. If you only have occasional use for such a service, then it's your job to check credentials. Your trees are a big investment, as you have found out and not easily replaced or repaired. Never base it on cost alone or the first number you see in a phone book.

Pipdog, I have over a dozen of these as hedges and two as trees. They grow fast in our climate if given water, and they recover well from butchering. I'm sorry the ends of the branches got cut off, that's going to cause the ends of the branches to sprout out many shoots, which can make the ends of the branches too heavy. Here's what I would do, in addition to giving it water. When you see the new growth at the tips of the branches and all along the length of the branches, make sure that growth is somewhat balanced. If you can get on a ladder and pinch off or rub off unwanted fuzz/sprouts to allow the tree to send energy into chosen sprouts that would be ideal. You can consider this an opportunity to remake the tree into a shape you like. If necessary, you can get an arborist out in the spring to choose which baby branchlets to save and which to trim off. They may charge the minimum, since there will be no real waste to dispose of. It is best to do this in the spring, since our summers are too hot for pruning most trees. Good luck, and if you think the guys in the Tree forum are bad, for God's sake stay away from the Landscape forum. Renee

It sounds like it didn't make it- but you could wait another week before pulling it to see if you see leaves. Mine, here in Il, are all blooming, so it makes me think that it's dead. Luckily, it's not too expensive to replace. 3 of my rose bushes didn't make it as well. :0(

Tree Ferns - The Secret Tree Fern Fertilizer?

There are many different species of tree fern that come from all sorts of different habitats. Do you have an ID for yours? Some tree ferns drop their fronds soon after they dry off. Some retain the dead fronds for quite a while. As long as there's plenty of good fronds in the crown of the plant it does no harm to cut off the ones that are dying and looking bad. As long as they have plenty of water some tree ferns can cope with full sun. But that's not all species. If you don't know the ID then stick with keeping it out of direct sunlight, or in filtered sun at most. Remember that indoors the air get's quite dry so the plant will appreciate a bit of misting.

Winter kill, followed by fermentation of the dead sap. Sorry, but they're dead, and have been so since the December freeze. The severe winter has caused a massive wipe-out of tree ferns across most of Britain (so you're not alone, if that's any consolation).

Karl - is there any way you could provide a 'canopy' to give your fern some winter shelter? Something evergreen, for preference. Pines, eucalypts, Pittosporum, Knightia, tall-ish Hebes.

Or, if they're too big for your garden space, some sort of attractive arch, or bush house/fernery which lets in the light, and that you could cover with wire mesh plus ag plastic for the winter.

If you go for the fernery notion remember that the roots are fairly shallow rooted and can cut short the careers of thirsty plants. I find that mollis azaleas, Aspidistra, mother of thousands Saxifrage, Dicentra, plus stray ferns such as Davallia, will all cope with life under the pungas. Hostas not so well.

If your fern is tall enough - you can also use the trunk for epiphytes and wannabes such as Gibasis, zygocactus, and Davallia.
