anchoring down trellis in high winds?

N. Arizona winds high right now. Lady Banks roses heavy on trellis, nearly blows down. tried anchoring stakes, doesn't work. Trellis is cemented into the ground. How can I brace the trellis so it stays upright.

It does not sound very well cemented if it is blowing over.

You may need to:
  • dig up the cement,
  • install some vertical pieces of lumber or thick bamboo,
  • add a crossbar to produce a frame,
  • pour new cement,
  • wait for it to cure, and then
  • attach the trellis to the inside of the frame.
Another option is to intercept that wind with some tall hedges or a wind turbine before it reaches the trellis.
