I potted up some begonia tubers in compost and lightly covered them in soil in the middle of April. Then I put them in my greenhouse and when there was no sign of any growth, moved them into the house. I have been waiting patiently for them to sprout, but only one out of twelve has shown any signs of growth. They are now back in the greenhouse, as I now have a new heater there. Will this help? Is there anything else I can do to bring them on? Thanks Janette

Were they very dry when you bought them, e.g., from a supermarket, which might slow them down?

I agree with Geoff - it's not that long yet, give them a chance.
