Q.How can I get synchronous flowering in Cyclamen?
I grow lots of Autumn- flowering cyclamen for sale at charity fairs but am always disappointed in the variability of flowering. How can I get the flowers to come together to give a display like the garden centre cyclamens?

Here is how we achieve uniformity in the U.S.
Cloning should be used to its utmost potential. If you find a plant that grows well, and flowers reliably, then this will be a perfect specimen to start. This will be a process spanning 1 to 3 years, depending on how many cuttings that you take and how many make it after that. Once an entire generation of this specimen is obtained, then it will be much easier to take cuttings from many plants, since they will all be the exact same genetic set.
The way to achieve cloning of this species will be to use ONLY tubers from the target plant or divisions of same plant. Any seeds let to grow from these will not be true to type. It is a very careful and selective process. Mostly a game of patience.
Giving them the perfect environment will be the only other factor once you have an equal genetic set established. This article will give you an idea of what they require: https://www.gardeningknowhow.com/houseplants/cyclamen/cyclamen-care.htm
