Hello, I collected to 2 semi hardwood cuttings off a mature horse chestnut tree from Garrettstown Woods Kinsale Cork Ireland. They are a bit flexible. Do they have any chance of rooting? Do they need a rooting powder? How do we do it to make them root, do they need a certain humidity, certain heat and would they do best in my greenhouse? That's all from me thank you to all the people who reply to me.

Olwas - As no-one else has replied to you, I'll do what I can.

Firstly, if you've just obtained the 'cutting' (and I don't know how you got it), you may find it difficult to get it to root. All this sort of thing, pruning etc., is best done when the sap is down in the root stock, i.e. in winter when the leaves are off.

Secondly, if it's only a twiggy bit, the way to take it is to hold the main stem and pull the piece you want downwards so that it comes away with what's known as a heel. Any help you give it thereafter will improve its chances so a dip in hormone powder and a month or two in your greenhouse will all help.

As always, give it a try but be prepared for disappointment. If you fail, there's no shortage of the species so you can try again.

go back next month and collect some conkers easier to get them to grow.
