One of my two french lavenders died. I tried transplanting them to a bigger pot because they've grown so big. I gave one a bit of a shake to loosen the roots as advised by my online research on how to transplant lavenders...and it didn't like it.
Lesson #8. When transplanting lavender, take it as is and don't attempt to loosen the roots because they are super sensitive they'll die.
This weekend I'm going to try to grow them from cuttings.
