Can you tell me how much safari 20sg to mix per gallon of water for a soil drench? Also, my soil is a homemade gritty mixture that allows water to flow right through, so will this product work effectively if it's just wetting the roots thoroughly, but not sitting there? Also have a large cereus peruvianus cactus that I will be using the soil drench on, so I'm assuming it would have the same instructions as the smaller (probably 1 gallon sized) cacti. Is that correct? I read to treat cacti using instructions of ornamentals, but wanted to confirm first.
To eliminate scale on cacti, it is best to remove the scale using cotton swabs dipped in alcohol to remove as many as possible. This article from the Missouri Botanical Garden has great tips on this and on general cactus and succulent care. They recommend using neem or pyrethrin as a contact spray, so we would recommend Triple Action for this application. The rate for Safari 20 SG for containerized plants as a soil media drench is 1.5 – 3 tsp per gallon of water and 2 lf oz of solution per 4 inches of pot diameter. You can see these details on page 10 of the product label. Since the Safari product label does not list cacti or succulents as tested plants and we do not have experience treating these plants, we recommend consulting with a cacti specialist and/or testing a few plants before treating a large area.
