I sprayed my roses with Lime Sulphur and received 11mm of rain on the same day. Should I spray them again?
Some of the roses I sprayed are bare rooted roses planted this season, others are old roses.

Hi Richelle,
How long before it rained? If the spray had a few hours to dry before the rain occured it will be ok. if it was washed off within an hour I would do it again.
