Dennis,

Thanks for your informative reply. Looks like I will just have to hope 
for the best until we get some dry weather. One point you made I had not 
realized or heard before, and that was to begin starting to apply 
Surround before bloom. I had been under the impression to apply it at 
petal fall.
