Hi. I have been growing tricyrtis for about 5 years. I have about 6 different kinds. I recently received some Latiofolia that aren't doing so well. They are planted in the same garden as my other toads. Within a relatively short period of time after receipt of my plants they are dying. They "mush" on the leaves and ultimately the whole plant lays down and mushes up. There is still a root system but no life in the plant. I treated for grubs and other like insects thinking this may be the problem since I did see some over the past month. They are gone and my Latiofolia are still dying one by one. They are in well drained soil and well shaded.
