The last of the tulips are in bloom now and the deer has left them alone. I treated the tulips only twice, but as some got slightly damaged at an early untreated stage, perhaps three times would have been better, but overall this actually went better than I thought and the Trico treatment really does seem to work for a long time and doesn't wash of with rain. For my conditions it doesn't seem necessary to spray every untreated inch of new growth immediately, but of course one need to use good judgment and reapply in a sensible way.
I'll continue treating Martagon lilies until bloom and in fact treated them today together with a few perennials, but this is the logical end of this small trial for the spring bulbs as the season for them is over now. I'll however update if I encounter any problems or as needed. Although I'm very positive for now, time will tell if this is a long term solution or if deer eventually will get used to the spray.
