Q.What\’s The Disease Of My Gladioli?

Zone 6 | Turagrong added on November 20, 2020 | Answered

Corms of my gladioli have these spots on them. One type is small (but sometimes larger), circular and black, the other type is brown, larger and without specific shape. Both can be easily shucked and healthy corm skin is formed under them. The black ones seem to grow deeper into the corm, one of the brown ones had mold in the middle of it. Thank you very much

There are several bacterial and fungal infections that will attack these bulbs, unfortunately. You may require a microscope to ID them properly.

Using a fungicide before storage can help prevent this in the future. You can treat with a fungicide, now, and still plant it, but I would plant it separately and monitor the health of the plant and soil, carefully.

Here is an article that will help you to store corms:
