Just wanted to share a way kewl Web site that has full explanations
of dividing perennials according to root type.

Site has good videos to illustrate explanations.

If anybody happens to go there, I have a Q.

The "divide according to woody roots" section includes Lavender.

But when I went to the section about in which season to
divide, it included Lavender among the "advise not to
divide".

Your wisdom? This is So Calif coastal.

TIA
