Bedding plants

I'm absolutely rubbish at growing geraniums,  busy lizzy or begonias so I usually buy some in.  Being a bit tight fisted I look for bargains in mini plugs and bring them on in the gh.  Year after year I've gone against my better judgement and bought from T&M or VM each time ending up in an argument over late delivery,  poor  quality,  etc.  Yes they replace and yes they refund, but it's getting beyond a joke.   My question is, next year, where can I get reasonably priced mini plug bedding plants that are reliable.  I've said to myself I will not use T&M again.

Why not pot up one or two of each in the autumn and keep them indoors over the winter, then take cuttings in the spring? Geraniums, impatiens, and begonias all need only minimal care over winter to keep them ticking over, and cuttings grow so easily from all three.

Sounds like a plan. Thanks Moth
