So I'm guessing this is your winter time right now? as it's our spring going into summer. I'm going to look more into the weedy options because I am a big fan of caterpillars and flying insects.
what are you using to keep the frost away? normally I cover mine with a mulch and the bottom of the plant with old clothes sometimes works, but I tend to have in the past gotten quite a bit of plant death through the colder months.
someone told me the other day to cut a pop bottle into two and use it as a little mini-greenhouse, I don't know if that's an option for you? :D
