Dahlia new shoots

I planted my dahlia tubers in pots in cold greenhouse, and some are beginning to show through the soil.  One in particular has new green shoots approx 4 inches tall.  How tall do they need to be before I pinch the tips off, will doing this help them to bush out?  They are all single flowered dahlias which I believe are more interesting for the bees.

    I've just finished potting up 9 single dahlias all I do is when they have a new pair of leaves I pinch out the top growth

    Also I'd add I've always got mine from wilko but this year I thought I'd pay extra and get better from Thompson and Morgan. Absolutely no difference. Wilko  £1 each been in ground for 4 years never dug up the tubers either

    Have to agree with the Wilco dahlias, I’ve got some, very good.

    I bought mine in the Pound shop and they were beautiful last year. Still in the ground and hopefully they will be as good this year.

    I plant loads of dahlias and find bees love to sleep in the single flower types.  Late evening and early morning the plants look like bee dormitories. They absolutely tickle me.  Have you considered taking some cuttings to increase your stock? I brought mine into the conservatory to bring them on and have been taking cuttings all week. I'll ram as many as possible into the garden and gift the others
  • I am not that greenfingered oooft - I wish I was though.  I know I could be saving a whole lot of money if I could take cuttings of all the plants around our garden. Thanks for the tip and well done  for being so generous with your cuttings, what a lovely gift for a friend.

    My dahlias are still not showing. Got them from Sarah Raven and have lightly covered in compost on sunny windowsill. Should I mist them with water? It has been 3 weeks now and no show yet  :(

    They do need watering like any other plant, put them in a shady spot.
