Q.keep Iguanas from eating my flowers and herbs
How do I keep Iguanas from eating my flowers and herbs… loves the basil. We are in a Marina and do not have the option of removing sidewalks or putting up fences from preventing a large iguana from eating our flowers and herbs… especially the basil. Is there any type of plant (like marigolds) we can plant that will keep them away? Will a plastic owl keep them out?

I have not been able to find any plants that deter Iguana.
Here are a few links for you.
