You are most welcome. The book Plants From Test Tubes is a fabulous reference book and well worth every penny. I am struggling to get through some of it since I do not have any kind of science background (not even high school science) so I loose a lot of time looking up definitions and concepts while reading. I am just an avid back yard hobbyist that spends her summers gardening and her winters dreaming of gardening.
I am supposed to be cutting back on my gardening...
but that makes me unhappy. I decided instead to focus more on the things I really enjoy like winter sowing, propagation and passing along my love of gardening to younger or newer gardeners that show an interest. The empty nest thing has provided a lot of opportunity to lean in to what I enjoy most.
