Dahlia Tubers

I've just received my delivery of Dahlia Tubers and all of the instructions say to plant in spring once the soil has warmed. As we have a cold snap forecast for the coming weeks, can I store my tubers in the shed (cold but dry) for a few weeks?  The tubers are soil free and in great condition so don't want to risk losing them.

Cold but dry is fine.

Hope that helps.

Should still be ok to do IMHO.

Which compost?

Any general multi purpose compost will be fine.

in the summer water it well but do not water log it, as a feed use baby bio around once every 10 to 14 days or so.

Avoid strong direct sunlight at all times. ( they do not like it )

in the winter reduce watering and stop feeding.

Avoid placing the plant anywhere near heat sources such as radiators and heating systems, where the temperatures change fast.

Ideal temperatures for this plant are between 60 and 70 F.

I hope that helps.

As most Osteospermums can only be considered half hardy, it's always best to propagate new plants by taking cuttings each year. This is preferable to over-wintering large plants.
