Patricia from Dunkirk, Maryland writes,

Can Bayer Advanced All-in-one Rose & Flower Care be used in a hose end sprayer for flowerbeds?

What if you want to mix it in a dial of fluid ounce sprayer? Can you do that? If so, what is the measurement of concentrate that I should put in the sprayer before attaching it to a hose and turning the hose on? I don't want to harm my flowers and I want the concentrate to be effective. I have quite a few flower beds that contain all different varieties of flowers and roses.


The Bayer Advanced All-in-one Rose & Flower Care is made to use as a soil drench, not as a foliage spray which is why the manufacturer does not recommend using the product in hose end sprayers. If you do choose to use the product in a hose end sprayer you must make sure you can properly calibrate the sprayer to only dispense the amount of product per gallon of water that is recommended for your use and you should only use the flowerbed dosing as you will also be spraying the plant leaves:

2 fl. oz. (4 TBSP) in 2 gallons of water treats 12 sq. ft.
