| Hi Viv,
I have read that multifloral Phals like equestris and stuartiana and hybrids made from
them are more susceptible to bud blast. Could be genetics. Also as Mike pointed out,
humidity can be a problem that causes blasting as well. I just was discussing this topic
with one of our local growers last week and he told me that low humidity is one of the
attributing factors to them blasting. Moving them from one location where the humidity
was higher to another location could possibly cause it.
