Hi Penny.
What kind of exotic plant do you have?
Plastic should be fine as long as its white/transparent and does not touch the plant (use stakes or a trellis).
Some exotic plants probably won't survive winter even with mulch and wind protection (at least not one as cold as last winter - shudder! ) - for instance if it's cannas then you stand a better chance by digging up the bulbs and storing them in a dry/dark/cold place. |
