I’m giving a talk next month about reproducing plants asexually and am working on images for the slide deck. Figured I may as well share some of the images here too as it might help some folks who are interested in doing this. Questions and feedback are encouraged and appreciated, they’ll help to make the presentation even more informative.

    Thinking about propagating some wild black raspberry I have in my yard - when would you recommend cutting canes, and should I root them before planting out? I’ve seen people store dormant canes over winter and plant out in the spring, what are the advantages/disadvantages there?

      I’m in the process of cutting my black raspberries now - they’re the ones pictured. My preference is to “tip layer” them, essentially leaving long canes with the tips pinned to the ground in early spring for cutting free around now. I leave other canes for fruit with a “heading cut” to force the side branches where the fruit forms.

      I like fall planting better, but I’ll qualify that with “for temperate climate areas”. For New England in particular autumn is when insect pressure decreases, precipitation is a bit more regular, and temperatures are kinder to plants. Plus there’s additional time in the ground for the plant to establish, and it’s my belief that the warmer soil temperatures relative to air temperatures helps to drive root growth even while the aboveground sections are dormant.
