Dividing is better than cuttings, Dove. Late winter or early spring is best. French Tarragon is unknown here in Italy despite it sometimes turning up in Sienese cooking. In fact it's supposed to have originated in Siena. Anyway, the only way we can get plants is to have friends bring them from Australia stuffed in a tennis ball tube with the roots wrapped in wet tissue paper.
Don't know what your winters are like but if it doesn't get too freezing cold you can cut it back and cover it with fleece or mulch. It will come back. It's so rare and prized here that I keep it in a pot. In winter it's wrapped in bubble wrap and fleece under cover.
