- Tiffany T.Verified BuyerRated 1 out of 5 stars4/22/26Poor germination
I've never had such a low germination rate on kale EVER. Where I live, once you get it started it's like a weed. It never dies and just grows into a tree. I have zero kale plants in my new garden because I bought my seeds from BI this time instead of a competitor.
