Just called a friend who has been growing one for years; she said she does her heaviest butchering in the spring, but if it is too large in the fall, she hacks away! I know she cuts off quite a bit as it is a fast grower.

Thanks Phyllis!!!

I know this is a REALLY old thread but I’m having trouble finding good info on overwintering Mona lavender. I’m in Zone 5...do I have to bring it in? I do have a sunroom, but I planted it in a bed not realizing it might not winter well. Should I risk transplanting it to a pot (it’s also pretty big) or is the bigger risk making it go through an Ohio winter outside?

Alyson - Mona Lavender is not hardy in Zone 5. You can transplant it into a pot to bring indoors, or you can propagate by rooting cuttings either in water or soil.

You should look in to what kind of Lavender is growing at the lavender labyrinth in Michigan... if theirs overwinters, it should overwinter in other northern states too I would venture.

I have no knowledge about moving lavender indoors for the winter. Sorry.

Mona Lavender is not a Lavender but Plectranthus, with beautiful lavender colored flowers.

I have one I've overwintered for a couple of years. I put mine in our garage, which is heated to 40-50 degrees I live in Michigan, about zone 5 1/2 where I live. I don't water it either until about March. Then prune and water. Mine is huge too, but I let it be what it is until early spring since I have the room. If I brought it in the house I would cut it back a bit in fall too. They really are a beautiful plant, just loaded with blossoms a couple of times a year, not so much in the hot hot weather though. Mine is still in bloom in the garage in late November.
