Title: Problems with winecups in Taylor, TX
Answered by: Barbara Medford

QUESTION:

I live in Taylor in Williamson County, Tx,. I have wine cups growing. They are lush and blooming, but I am now noticing what looks like spores forming under the leaves and the plants seem to be suffering from it. Do you know what this could be? Baking soda mix with liquid soap a possible remedy? This is their 2nd year in the garden. Rock on with all the help you provide gardeners!

ANSWER:

There are 4 plants native to Central Texas with "winecup" as one of their common names. Since you mention this is the second year for your plants, we are going to say it is the perennial Callirhoe involucrata (purple poppymallow). We are puzzled by the presence of the spots, but our webpage on this plant mentions that it is susceptible to rust during wet seasons, which we are not having right now in Central Texas but have done earlier in the year. We also noted that it must be in well-drained soil. Since it is somewhat a trailing plant, we think the moisture of the soil might be the first suspect, causing rust or perhaps a little mildew. We have also heard complaints about the numbers of snails and slugs that are around this year, also because of the moisture, but that doesn't sound like slug damage. As long as your plants appear healthy and are blooming, we wouldn't worry too much. Avoid over-watering and try to improve the air circulation around your plants, perhaps with some shredded hardwood mulch beneath the plants to get them off the soil.
