Carefully wrap the moss in the plastic, because i used Press-and Seal it sticks to itself so this part becomes very easy.
Once the soaked moss is wrapped tightly in its plastic wrap case i used string to tie the top and bottom of the package to help keep the moisture inside through next few months.
Notice that i tied bows and did not tie knots. Last year i tied knots. When i got ready to take the wrappings off the cuttings - i could hardly get the knots out because the branch kept growing and tightened up through out the summer. My suggestion to you is no knots!
I am done for now - there is nothing that i can do until around Labor Day. Last year i checked one "package" every month to see how it was doing, to see if it was staying moist. To my surprise it did stay moist through the whole Summer. There was no activity until the weather started to cool off - here in zone 7b that's around late August or September. Once i saw roots, i clipped the branch below the new grown roots, and planted them into recycled black pots. This was one of the most successful projects i have tried unlike rooting clippings, or rooting in water.
This is definitely the way to go!
Of the 12 that I started last year one died on the bush, and one died after i planted them up. That's a good success rate compared to zero plants that survived as clippings. I hope this inspires some of you to try this easy method, i love it! As soon as school lets out in 16 days i'll be trying crepe myrtles.
