Transplanting Parsley

We recently purchased a plug of curley parsley from a local grower, it's time to plant up, I have a couple of questions: 1. What size containe do you recommend we have the standard 3 1/2 " square pots available. How many plants should I place in on 3 1/2 " pot ? 2. How do divide the plant, looks to be as many as 5-10 in each cell, whats' the best way to get that long root planted. Any advice would be greatly apreciated.

You would do best not to disturb the plantlets in each plug-just move the whole plug on to your 3 1/2" size pot. If there are 10 plantlets per plug a larger pot might be a good idea.
