Can Fertilome Natural Guard Horticultural Oil RTS be used while a plant is just starting to bloom?

Satsuma and meyer lemon are in bloom stage now.

Answer:

The product label states Fertilome Natural Guard Horticultural Oil RTS is a dormant and growing season insect spray, so the product should be safe to be applied when lemons are in bloom. Keep in mind that this is an oil, so it could kill pollinators such as bees if you spray them with the product. For this reason, we recommend being careful when treating around blooming plants.
