have rooted a few by cuttings in the later part of summer, but lost a few cuttings also. i am trying by seed today, but some of the seeds are dried up like a prune. do have some seeds that are pretty sturdy almost like a popcorn seed. does anyone recommend anything special to do for seed before i plant them?
Here is how one of our DG VERY informed members does it:
Seed germination can be tricky. I have had best results NOT presoaking the seeds. They draw up water too readily, and will rot easily, if pre-soaked.
I usually start with moistened soil-less mix, and then squeeze it as hard as I can, to get all the water out. The moisture that is left in the soil-less mix, is now just right (barely moist and a bit on the dry side).
Put the soil-less mix in a container with seeds, and cover. Remove and sow, as they germinate. Germination is erratic. Seeds may germinate at different intervals over a period of about a month. Some may germinate in as little as one week, and others may take up to a month.
I have also successfully Propagated this by layering. Layering is actually the fastest and easiest way to propagate this vine.
