Ground cherry seed saving
This year one of my interests is saving seed. Last year I grew some ground cherries and really liked them. So this year I will be growing them again, but would like to save some seed.
I know that none of my neighbors are growing them, but I'm concerned about cross contamination from other plants. Since they are cousins of tomatoes and tomatillos, can they cross with these cousins? Do I need to ensure that they are far enough from my tomatoes so they don't cross?
Thanks in advance.
