The Asiatic Lilly That I Have In Containers The Leaves Have Started To Turn Brown And Black. Some Of The Flowers Have Also Started

Question

to have translucent spots. One container some of the flowers I had to cut the stems down because the had also started to turn bla ck. The black and brown leaves started turning at the top of the plant and went down the stem. There were two that started at the bottom and worked up the stem. This is the second year that I have had Asiatic Lillies in containers and I do not remember the plants from the previous year doing this. The containers have drainage and the plants were fertilizerd earlier. I also checked for bugs/pests but did not find anything. I thought that may have had a fungus so I did try baking soda/ water mixture that I had read about treating lilies with. After I sprayed the plants with the compound I don’t think it hurt or helped them.

Answer 1

I see what appears to be two or three issues, separately.

I notice what appears to be severe overwatering symptoms and bacterial damage. Also, likely, overfeeding has compounded the damage.

You will need to treat with a fungicide/bactericide, and correct watering habits. Cut back any growth that is heavily infected.

Make sure to water, only, when the soil is completely dry down to about 3 or 4 inches in that type of soil.
