Sealing your cut ends using Dap.
Dap is widely used for sealing bathtubs but it also works with sealing the end of cuttings, the pictures below is how I use it and have very good results.
Once you make a cut on the mother tree wipe the end with alcohol and then apply dap it should seal the cut and get new growth, remember to cut at and angle so the end does not collect water.
This is the product I use but most of them will work, you can use any colored Dap..
Here are some mid cuts that I wiped down with alcohol and applied Dap.
Here are some cuttings that I applied Electric Liquid tape. This also worked pretty well sealing the ends.
