For several years, I have planted tuberous begonias in the pots on the north side of my house and they have performed very well. In fact the large blooms have been perfect as I come and go from my house. This was not the case this year. The plants started out looking great during the month of June, but July took its toll. They developed powdery mildew and some rot caused by the heat. Last night it was time to rip them out and replace them with some ferns. There is still a lot of summer left. If a few of your plants are not looking good as was my case, they can easily been replaced.
