Overwintering Perennial Herbs
Hi, everyone! We know it may be too soon to ask but we wanted to be prepared. How can we overwinter perennial herbs within zone 9/10 where the winters are quite mild? Specifically, sage/rosemary/lemon balm/tarragon. All grown outside in the garden as of spring this year.
Do we have to cut the plant down to a stalk or leave it as is? Do we water it once a week in the winter? Cover it with mulch? Any advice would be appreciated. Many thanks, guys! :-)
