I've tried rooting a red passie from a friend but couldn't get it to root.
What is your best method?
rooting passifloras
I need to watch this thread as I'm having terrible luck as well!
Try "air grafting", an approach your friend will need to accommodate, but what are friends for, right? All you're going to do is put a small clump of soil on one stem of her passi for a couple weeks.
Start with some very light soil --take it from one of summer's annuals now passed, or mix half peat moss, half perlite or vermiculte. You will only need about a cupful or so. Add to the cupful a pinch of dry moisture-absorbent crystals --not too much.
From a store-bought-vegetable bag --the slightly porous type, in which celery, carrots, romaine are sold-- cut a 4" x 8" rectangle.
Find a couple of wire ties, or some velcro tape.
You 'll need some rooting hormone (eg, RooToneF).
Take everything over to your friend's plant.
Pick a leaf/blossom node on the plant that is 3-5 nodes in from the end of a strong shoot. Gently pluck all the leaves/blossom stems from the node, then with a fingernail or a butter knife gently scrape the surface of the stem above and below the node, right up to the node. All you need to do is expose a slightly greener, slightly moist surface --be careful not to crush the stem.
Dust the scraped node with your rooting powder. Now wrap the 4x8 porous plastic-wrap piece around below the node, with the 4 inch edge along the stem, the 8 inch going around. Overlap the ends by 1 inch, twist/gather the material around the stem and secure tightly with one of your wire ties or tape. You've now created the bottom of the "bag" that will hold a small clump of soil around the powdered node.
Now you just need to fill the bag carefully and tie the top. Straighten out the material around and above the node, so you can first slide a bit of soil below the node, then cover the node with some more.
Moisten the soil thoroughly, squeeze it dry between your hands, like packing a snowball. take about a third of it, and squeeze it into a flat cake about 2" x 2". Slide or shove this hunk of soil into the "bag", under the node. Do the same again on top. Wrap the bag around the set up and squeezethe two hunks together around the stem. Carefully open up the bag and add more soil if necessary, re-wrap, re-squeeze, tie off tightly at the top.
The clump should hold enough moisture to get the node rooting. If you have cleverly left the seam of the bag opening upward, an occasional dribble of water into there will ensure that.
Check it in a week or two. If you don't see roots through the plastic wrap, open the bag from the top and explore into the soil. If nothing's going on, well, sorry, we tried. If you find they've started, just slowly, re-wrap and let 'em go another week or till the roots just hold together the soil clump.
When you reach that point, clip the rooted stem off (BELOW the node --don't laugh, it's happened otherwise), and plant in your desired location.
Go for it, good luck, fill us in on results.
