I've some tubers bought and some saved. Should tubers be planted now and kept indoors then? The destructions which came with the bought dahlias says plant in April?

Zoomer-you can plant in April in the garden -but it is a bit dodgy-much better to start them on now -then transfer to the green house-then plant out at the beginning of May or so.

They need to be not to wet- but warm to get get going

I put mine in some shallow compost in the house Geoff looked like they already had little nibbs of sprouts on them. Depnding on how many shoots they get I may take cuttings (do you know if its best to dip them in hormone rooting powder?). Also whats the growth difference or stage difference of a cutting as opposed to a seedling?

sotongeoff

Because of the larger leaf area you could say the cutting would be stronger-but because it is putting on roots before it puts on growth does that make the seedling stronger that has little leaf growth or roots??

Honestly -I don't know-someone will though-they all seem to catch up in the end

I haven't used rooting powder for years on anything-if you have some then use it-it can't do any harm

I put my dahlia tubers in trays on compost that is just damp and mist them two or three times a day. They need a bit more warmth, though, than just frost-free. They soon shoot and will then tolerate lower temperatures.

I read somewhere recently about planting dahlia tubers in a heated propagator so maybe that's a clue that they do better if they're warmer.

Geoff. Haven't started mine off yet but checked them today, they've been kept in damp compost over winter, they look healthy, a couple have shoots and I've two tubers bought in February from the GC. 

I plan to grow them in a trough, reading your reply, would it be ok to plant them in a trough in April and move the trough into the shed if there's a frost.

Space is limited indoors as veg seedlings take priority although at present there are few, by the end of April the back bedroom will look like an oasis

Zooms-can you put the trough in the greenhouse to give them a bit of warmth and protection in the first instance?

No probs, can put them in the GH

I placed mine in a tray of compost, not to firm, and dampened. They have been in the house in warmth since & not a sign of any movement. I suppose I am being a bit impatient

Mine neither dave but I shall wait

I have read that they can take upto a month to sprout

Bunny ...
maybe if I sing to them they will do something

They tend to make root first -then sprout

I don't think they are going to do anything

I stored all my tubers in a box pushed under a wardrobe so to keep them in the dark. They all survived and 2 weeks ago I potted them all up and I now have shoots about 4 inches tall. I usually put the whole tuber in a pot of damp compost but leave the old stem sticking out.

Why not sow some dahlia seeds as a back up. I was going to start sowing my Dahlia seeds from a seed swap at the end of the month. They flower the same time as plants grown from tubers and you get a huge tuber at the end of the summer.

I just haven't managed to get any tubers to grow the following year after being stored over winter. Hoping for better results this year.
