to be honest I wouldnt use a propagator for rose seeds. I would sow the and leave the pot outside in a sheltered spot. but others may have had experience of growing rose from seed.

Take Seaburn's advice on your rose seeds and good luck!

You might like to have a look at the RHS Propagation book - it has lots of information on the temperatures that different seeds need. Otherwise, when you buy any packets of seeds, it gives you the temp. needed on the back.

to seaburn girl thanks for your advice but it states on the seed advice that they must be kept at a constant heat of 20-22c for germination to take place,it mentions to grow in vermiculite but does,nt give any quantities or if this is to be mixed with any particular compost so any further advice will be very gratefull thanks again brivin

I've just read my Propagation book on rose seeds - they need stratification before you sow them. So you'll need to put them in the fridge for a few weeks - in a damp paper towel inside a plastic bag.

Then sow them in a 50/50 mix of vermiculite and sterile potting compost. (You could sow them and place the whole tray in the fridge if it's convenient)

Place the tray outside in a frost-free position and don't let the medium dry out. There is nothing about the high temps you have found. They'll take about 6 weeks to germinate.
