@debs69 Really easy. You can either break them off and put into a small pot with compost &provided you keep them in a north or west facing window, not in the sun & keep them moist they will root.This layering method is practically 100% successful. Fill little pot with compost.Put baby spider in and make a little u shaped wire to anchor it down into the soil.Look closely I have anchored the stem with green plastic coated wire cut into hairpin shape. Don't keep it in greenhouse too hot. Cool house
@llsonRootsProject Yes you can do strawberries although I find it easier just to cut of the babies & put them in compost. This is not really layering it's just propagating. I layer all kinds of shrubs. The most successful have been Rhododendrons Azaleas Potentillas Cotoneaster but any springy shrub is worth experimenting with. Find a low down branch and ease it flat onto the ground. Mound some soil over it and put a wire u shape on to pin it down or sometimes I just put a stone to secure it.
@llsonRootsProject contd. As long as the branch is in contact with the soil it's fine. Sometimes people put a slit in the branch to encourage roots but I've never needed to do that.Leave it & don't disturb it looking for roots. You'll recognise when it's growing & then you sever it from the main plant & pot up. To find out more Google Propagating plants by layering and this will give you more info. I'm just passing on my personal experiences. Good luck
