Also, should soil be dry, wet or? The leaves on my 2 of my rose bushes have holes throughout the leaves and dont know when I should spray it on, before sun up or after sundown. I also need to know can the soil be wet or should it be dry? Please advise and my leaves are being eaten up quite quickly.
Bonide All Seasons Horticultural Spray Oil is applied to the plant itself not the soil, so the soil moisture is not a concern. You apply in the early morning or late evening when temperatures are lower, never during the heat of the day.
