Nothing fancy for me as well for my two vines. With our mild winters, they can be left outdoors.
My Mandevilla uses tomato stakes and is such an escape artist, it has now managed to twine some vine in one of my hanging containers. But I know it will slow down in growth come winter time, so I will have to do some pruning.
My Passie uses those wooden trellis commonly found at Home Depot, it is in its first year here, so I want to observe first how it endures our long dry months, so far it did well. Now heading into the cooler period to winter, will see how it goes once the wet winter weather returns and occasional hard freeze warnings during winter.
