Hi,
hoping someone can help as my pride and joy is about to keel over I think! On of my Cordyline Australis is around 7ft high with trunk diameter of around 18/19 inches and was I belive firmly planted in. This has been sound sound for around 3 years but lately I have noticed its starting to lean and I fear the roots are being stressed due to this, yesterday I took a good look and its baffling me how its staying upright, thats how much its leaning.

What are my options to fix this?

1 - Use strapping of some sort to try and pull back ot to at least offer support and minimise further damage? If so can I buy in the UK?

2 - Look to buy some sort of stake again to offer support, but wonder if this could do more damage

3 - Dig down [missing roots!] and replant the tree upright. I dont favour this option as could potentially kill the root system..

Any other ideas appreciated and thankyou for reading
