Firstly, I am a inexperienced gardener with regards to plants. So if anyone can give me some advice please make it simple so even I can understand. Thank you.
I have 30 Dahlias in individual 20cm (8'') pots. I bought them as bedding plants from a supermarket & I have a great display from them all Summer long.
Two days ago I read an article - Daily Mail - by Monty Don; 'How to make your Dahlias last forever'. He said it should be possible, after the first frost, to cut the plants down to ground level, cover them in a mulch & leave them insitu. in the garden throughout the Winter.
I intend following this advice but bringing pots under my car port which is always a few degrees warmer than outside. However, the MD article mentioned Dahlias tubers. My plants were bought as bedding plants, they were not tubers. I need the following advice;
1 - Are there two types of Dahlias? One with tubers that can be overwintered & one without that can't?
2 - Or, do the non- tuber Dahlias develop tubers as they grow?
Forgive the naivety but it seems silly to me to try & overwinter something that will die anyway.
I hope I have explained this correctly.
Dahlia experts please help!
