Name: tarev San Joaquin County, CA (Zone 9b) Give PEACE a chance!
My mandevilla is such a climber so I have it on a tomato cage/trellis:
This grid cube serves both as a plant stand and trellis for my Hoya carnosa 'Krimson Queen', other smaller plants are either hanging there too or just using it as a plant stand. Since this hoya can take our winter cold temps, it stays on the patio outdoors year round.
My Hoya kerrii variegata came with its loop trellis, which I just kept as is. I have added a stick for the vine to loop around, since the vine is thicker and tougher to loop around. Then I have the container sitting on a metal chair plant stand. I placed the metal chair at the lowest portion of the grid cube for added bottom support. When winter comes in, Hoya kerrii variegata will be placed indoors beside my orchid pole near a west facing window. I initially wanted to use the grid cube too as a trellis for this Hoya, but i realized it will be difficult to remove it if I have to move the plant indoors for winter, so I kept it as is on its loop trellis.
