This is my first shot at taking cuttings of any sort. Recently Monty demonstrated taking penstemon cuttings on GW and at the end said, "Put the pots somewhere warm." I was going to put them in my polycarbonate cold growhouse as I don't have a greenhouse. Will they root in there, up in North Yorkshire? Should I put polythene bags over the pots? Do I need to mist them as Monty said? Should I mix grit in with the MPC?
One other slightly related question. I have so many small used plastic pots of varying sizes and I've often wondered whether a 3"/9cm pot refers to the base or top diameter measurement. There again, there are deep ones and shallow ones with the same base measurement. How deep a pot do I need for cuttings?
Sorry for so many questions. I only want to do what's best for my little ones!
