Basal Rot on lilies
On Monday I went to a lily presentation put on by our local gardening club. At the meeting Fusarium and bulb rot was talked about.
Since I had several stalks from bulbs that appeared stunted this year I decided to dig them out to check what was going on. The first bulb appeared fine. But my second one had completely rotted at the basal root. This bulb was Heathers Promise. Another garden club member had the same thing with this Heathers Promise bulb.
On another forum it was suggested that I dig 18" deep and 3 feet around this bulb to remove the soil and the fungi that was present. Lo and behold in this area, I found another rotted bulb, right beside my Heathers Promise. This bulb bloomed but the last flowers seemed to shrivel up rather than open. Now I understand why. So now my 3 ft area just got bigger.
I now have 50 or so lily bulbs to plant, but am very paranoid about putting them in my lily bed. I have stirred up the soil quite a bit by moving things around and planting new.
So I think that I am potting up these new bulbs and making a couple new raised beds next year. I'm also thinking that my lily bed might have to become a new rugosa rose bed.
I've been searching on the net and other plants are susceptible to this fungi as well including daylilies, irises and peonies.
It is kind of scary that this fungi can live in the ground for 4 years without a host. Time will tell if I have eliminated from this bed or spread it around.
