Browning leaves

I have a lot of flowers that the leaves get brown on the bottom of the stems. Is this a virus or a mineral
difeiency It does it every year when the weather starts getting hot. It's happened on loose strife, Phlox,
and others.

This is a disease that occurs on some perennials, especially those you mentioned and also on asters. You can treat them with Bayer Advanced Disease Control for Roses, Flowers & Shrubs according to the label directions. If you start treating early, you may be able to prevent the disease. Read and follow the label directions. Keep your plants mulched and watered during the hot summer. Feed them with Plant-tone in the spring and fall.
