In an ideal world, woody plants like the ones you mention will have at least 4 weeks in the ground before first frost. Your plants need time to prepare for winter. I have little hesitation about planting the oregano and lavender as they tolerate cold weather better than rosemary. Overwinter the rosemary indoors as it doesn't tolerate temps below 30 F. Rosemary does much better than the other 2 when grown in containers and indoors. They all need fast-draining soil. If your soil is heavy clay, you will need to amend it with coarse sand, small pebbles or perlite. Soil should dry out, almost completely, between waterings. They are native to semi-desert regions and are used to sandy soil, lots of sun and sparse water. The roots may rot in rich loam.
