I spotted new shoots on greenii, coccineum and Devon Cream over the weekend.

Some new culms do emerge inside the clump but I can't say whether they would necessarily come up where you have thinned out, or if they will necessarily be larger than the ones you removed, but I would give it a go and see what happens next spring.

I don't know about toxicity, but those hairs on the sheaths of Fargesia robusta can be quite an irritant when they stick in your skin. I remember last year when I was removing old spindley culms from the centre of the clump, I got them all stuck in my forearms.

No show from mine yet. At least, not last weekend when I last looked. I will go around and check again tomorrow. Potted H. greenii and cannas in the conservatory are growing away but nothing outside. Plastic bell cloches over hedychium clumps help them into growth sooner. EDIT: I noticed from an old...

They grow from the top of the culm so cutting the tops off should stop them. I don't think that is quite true or at least not the full story. I have taken a broken-off juvenile culm and gradually peeled away the sheaths. Once removed, you can see all the nodes are closely packed together towards th...

for ground cover, I would stick with evergreens ..... there's no point in having pretty flowers for 2 months of the year, and bare soil for 4 months of the year I find a mixture of evergreen and herbacious/deciduous is the best way to go. By sticking with evergreen you eliminate a lot of rewarding ...

I particularly like Colocasia's (formosana), asarums and cautleya. Colocasias are better grown as anuals or at least dug up and stored frost free. there are a couple of hardy varieties that some people have succesfully kept outside. Namely Colocasia fallax and Colocasia gaoligongensis. Not heard mu...

mines only a small garden which is hard landscaped so iam going for a pot garden swings and roundabouts i can move to a warmer spot come winter,the cerifera changes colour with more sun(so i was told) icon_scratch I would forget the swings and roundabouts and buy more palms. Let the kids go to the ...

Yes, it's very easy to remove the unwanted bits though, and you can pot them up to make new plants. It's hardly a rampant invasive. I don't think it warrants a sunken pot.

It's interesting how sunset pictures often get comments like "Wow that could be somewhere tropical". I Think that people often don't realise, or forget that sunsets in this country can be as stunning as anywhere else in the world. The trouble is that we are either too busy to notice them o...

E. bicolor has self seeded for me but Sparkling Burgundy, Zeal Bronze and Pole Evansii never have. I collected the seedlings from around the base of the plant and potted them up until they were bigger, then planted them back out. I've had a couple of 'Sparkling Burgundy' outside, one for 5 years, th...

I would say you can't put a date on it. You have to go by the weather, which obviously can vary up and down the country and also from year to year. Mine would normally probably be unwrapped by now. If it is mild, you need to unwrap to let the air to them because rot can set in and spread to undamage...

I think it looks too smooth for a Cyathea trunk. I would expect some remnant of scales like the pic in the link.
Lots of plants leave leaf scars like that, Philodendron for example.

I have used the plastic cloches on tHedychiums for a couple of years now and it definitely makes a diiference. I can't put a figure on it, but they can languish in the soil until well into the summer if you don't get some heat into the soil, so it greatly improves the chances of flowering before end...

No, they will do it all by themselves.
