This 6 foot monster is from seed planted in spring 2014. Kept in a pot until this summer. Now in the ground it has gone crazy! To dig up or not to dig up, that is the question? I'm considering the possibility of mulching it well & leaving in the ground but worried it won't survive a hard frost 😕 Any suggestions or comments from anyone with any experience of these beasts would be most welcome!
You may need to be brave! Monty cut his back and brought it into the greenhouse. Depends where you are as you could cut back and mulch but that doesn't help if it's a wet winter. Your call really do you want it next year for definate? Then I'd cut it back and lift it if you have somewhere to store 🤔🤔😬
Thanks Hayley. I have clay soil, so I think you're right @hayleyaj as it won't like the wet. This will only be my 3rd winter in deepest St Helens. The last 2 have been no colder than about -6C, but I have space in my greenhouse, but I'm figuring on the tuber being humungous so a big pot will be needed! 😀
Jeff, mines clay too. I won't be risking even my std dahlia, let alone a beauty like this!! Just check if you can dry the tuber out for this rather than pot up over winter. As if you can, it's just lots of newspaper in a dark dry spot 🤔🤔😃
Cheers @hayleyaj No flowers yet & no sign of any flower buds either. Had in a pot in the greenhouse in the last 2 winters, so I think I'll stick with that, keeping it on the dry side. I may put it out in a very big tub next spring though. We will see?
