Q.Growing Wild Strawberry plants
How & where do you keep these over Wintertime in a hanging pot ? And will they come back ?
The health of your plants may be effected by their storage during the winter.
Container plants are vulnerable to cold and freezing temperatures in containers and should be stored in a garage or someplace similiar.
