I’ve tried a number of ways to try and maximise the productivity of my plants in terms of propagating from leaf-cuttings.
A recent trial of dividing individual leaves in half by cutting down the central vein of the leaf and planting both halves has proved extremely effective! The last time I tried this I got 18 new plants from 10 leaves (one leaf wasn’t up to it but that happens to best of us!).
A couple of things to remember – use a sharp knife or scalpel and ensure that you end up with equal amounts of vein and stem material for each half.
I also ensured that the leaf halves were sat quite deep in the compost so that the base of the leaf itself was just in the compost by a half a centimeter or so.
