Thank you for this advice. In NH, too. Just applied your Castor Oil mix around my potatoe beds. Fingers crossed!
I watched your other video about castor oil application twice! This past winter the voles decimated my hostas and Japanese forest grass.. so upsetting! So this fall I'll be thoroughly drenching all my beds with this formula. I'm hoping a hose end sprayer will be effective enough, but if not, I'll get the injector. Thanks for your good advice.
Same. I’ll try this too. Good luck!
Yes! Love to see new NHHosta videos.
Watched both videos. Thanks for the information! I’ll be taking the advice.
May I ask how you settled on this particular concentration of Castor Oil to be effective?
Which model Dosatron(?) injector did you use in this video? I suspect that this and other general specifications for this and/or a similar injector will be very helpful for me and other interested viewers.
Is Castor Oil and detergent safe for vegetable gardens?
It’s February, and I just discovered vole’s throughout my garden. Can I apply it now? The soil is soggy after our PNW freeze then rain.
Can I use the same mixture to get squirrels away? They are destroying my garden and persimmon fruits.
Can you use the castor oil mixture on vegetables?
I watched your other video in which you recommended a 1:1 ratio of dish soap to castor oil in one gallon of water. (time stamp 2:48)l. Here it's different. (1-2 c castor oil:1/3 c detergent: 5 gal water) (time stamp 4:59). I'm a home gardener so won't be investing in this fancy system. Will the soap oil combo damage the plants. Looks here like you are spraying it on the plants as well as the soil.
Where did you get the injector
I would like to know if anyone has used a chemical injector system to apply the soap/castor oil solution through a hunter sprinkler system? I would like to do this I have the critters all over my property I am leary and cautious that my sprinkler valves or heads would get damaged?
there are companies that sell it. look up fertigation.
