I am planning to plant borage clumps between my tomatoes and zuchinni plants. Hoping that will help repel the pests and give pretty blue color as well. Not sure about spacing and reseeding issues.
Since it's an annual that reseeds well, does that mean that by end of season, it will spread through my tomatoes and zuchinni? Does it tend toward invasiveness?
How close does the borage need to be to the tomato or squash to be an effective pest repellent?
Anything other experience to share about borage?
