Taking dahlia cuttings. A friend very kindly sent me a Sarah Raven collection of eight dahlias & I've got them in pots in the spare room at the moment. The growing instructions say to pinch out the tips of the main shoot and to reduce the shoots to five. Please could someone tell me how tall they should be before I pinch them and reduce the shoots? I'd like to try growing the shoots as cuttings. As the photo shows, some are growing much faster than others, though all have good roots. Oh , and if the roots are coming through the bottom of the pots ( they are!) will it damage the plants if I have to break some of the roots to get them out of the pots when it comes to planting them in the garden. Though gawd knows where! I have no space!
