I have some splendid Diascia Personata plants, bought from Bodnant Gardens. All through the summer they have had an abundance of beautiful flowers and are at least 4ft tall. I took some cuttings from them in September (late I know) and they are growing slowly in a pot on my kitchen window sill. I want to know: Should I be cultivating them indoors or maybe in my garage where there is a window? Should I nip off the growing tips at the top of the cutting to encourage them to bulk up or just leave them alone? They look quite fragile at the moment and I would hate to lose them. Any advice would be appreciated.
I think this Diascia is relatively hardy so you should be able to overwinter the original plants (I found a reference they are ok down to -10C.) As for the cuttings, this article may help:
I would not put them in the garage. 1 window is not enough light. The plants outside will probably survive. You could put a little fleece around them on really cold nights and try to keep them dry. Assuming you do not have a greenhouse I would keep the cuttings indoor in as cool and light a place as you have got.
I had to googlethat one, never heard of them. Lovely. Do you reckon they'd be Ok in a cold GH Bob, if dry, when the temp goes down to -13C. It doesn't do that every year but it does happen
Thanks everyone. My original plants did survive through the last winter, without any help from me, so I'm hopeful they will survive again. (Thanks for the advice about putting a little fleece round them punkdoc.) I was eager to have some healthy cuttings so that I can have some more plants in the garden next year. I've never seen this variety of Diascia in garden centres before or since.
I'm going to try putting the cuttings in my porch. It is double-glazed and fairly bright. It has no direct heat but is obviously warmer than outside.
I'm appealing for help with my Diascia Personata cuttings again. I now have two small pots with healthy cuttings growing. The problem is, they are quite spindly and tall. They are currently about 8 to 10 inches and I've had to support one of them with a little stake to stop it falling over. Would it work if I pinch off the tops to encourage them to fatten up lower down? The plant I took the cuttings off is really tall, but the stems are fat and strong so they stay upright. My little cuttings are not going to be able to support their own weight, especially if they grow any taller. I am new to this cuttings lark, so any advice would be appreciated.
I've grown this plant for some years and my experience with over-wintering cuttings reflects yours. Keep pinching out the stronger stems to stop the plants getting too leggy in the dark days of winter. Cut out weak stems altogether. Harden off in a cold frame in March, plant out in April in favourable weather and they'll be flowering in May!
