A few tips if you want to try this:
1. I used a 3-gallon pot because it had to be manageable for me to move throughout the seasons. I used an unfinished trellis (do not use pressure treated wood! You could use any kind of wood stake add long add it's not pressure treated).
2. I used screws to attach the trellis to the bottom of the pot. I'm planning to reinforce to trellis at the soil line (still pondering this).
3. I used a mixture of cactus soil and a potting mix. Pot needs good drainage but the plant likes organic mix.
4. I used burlap strings to tie the cuttings to the trellis. You can use whatever you have as long as it won't hold water for an extended period of time (don't want to rot the cuttings) and don't tie too tight.
Hope this helps, Julie
