Early Dahlia

Hi, can anyone advise. I have started my Dahlias and they are growing so fast I may have started too soon.  Am I ok to cut away the longer stems and encourage new shoots. Thanks, Pottingmad

  • I think it depends whereabouts in the country you are and whether the risk of frost has passed...

  • In South Yorkshire. They are still in plant pots. Removed from conservatory and now in outdoor mini greenhouse 

  • I'm sure there'll be someone along in a minute who can advise you on your specific conditions image

    No idea about greenhouses as I don't have one!

    Pinch out the stems, it will make them more bushy and more flowers. If the stem isn't hollow they can be used as cutting. 

    I would bring the dahlia back indoors at night if they is any chance of frost.

  • Thank you. How would you take a cutting and root/plant.

    Just pop it in some damp multipurpose compost and place in a propagator / seal it in a sandwich bag etc and leave on a bright windowsill not direct sunlight though . Should take a few weeks to root.
