I had been thinking I could put a pole in the middle of the cage and tie the plant up as it grows, The wire netting around the cage is something I could do to keep the plant and branches in growing upright, thanks.for your mater cages you could wrap the round wire cages in the garden netting. It gives the support. Or you could build a tri-pod with a string from the middle to make the plant grow up. Just shorten the string as needed to keep the plant upright.
