Hi Floridagal! Welcome to ATP!
First off .. please delete your email address. It's not a good idea to publish your email address on a public forum. It's easy to do. At the bottom of your post, to the right of the acorn and thumbs up icon you'll see Edit. Just click on that and you can delete your email address then choose save.
As to your question, we need to know what kinds of plants you are referring to as a 'one size fits all' answer just won't do the job.
