avoid pest/bugs? Hey I went to a flea market yesterday and saw some Natchez blackberry plants and Triple Crowned something plants for sale. But the stem (no leaves on it b/c it's cold) is purple on some of them in spots? Is that a good thing or a bad thing b/c the plants I see in pictures are green stemmed.

Second question is once I buy one or two (I hear two is better to do than one) how do I keep pests away? Those bugs that eat up the fruit?

3rd question, do these kinds regrow or do they hvae to have a stem cut off and planted so it re-roots? (I don't know how to do this by the way, it's confusing)

thanks
