    Hello and welcome. I believe that your plants got too cold. Plug plants which are tender, such as begonias, need to be kept above 5° and sometimes warmer. There have been some very cold nights and even some chilly days and I think the temperature in the greenhouse fell too low.

    Begonias hate being too wet so that could have been a problem.  I kept begonia plugs in an unheated greenhouse for weeks and they were fine I just didn't water them at all when cold weather was forecast.

    Wet cold is always worse than dry cold - for lots of plants, not just these.

    Is it  also possible you potted into too big a pot? That adds to the problem, as there can be too much soil around small plants/roots, making it hard for them to thrive.

    I got sent a few in a mix (I don't usually grow them) and did the same with identical consequences.  Lots rotted away with (I assume) Botrytis.  I moved the remainder into my conservatory which, although unheated, stays at least 5C above the temperature in the greenhouse at night.  They are beginning to grow very quickly indeed now.
    A trowel in the hand is worth a thousand lost under a bush.
