Yes, Fertilome Over the Top II can be used over cactus/suculents.
Fertilome Over the Top II is a grass killer so it will bermudagrass and tall fescue grass.
Bermuda would be considered a grassy weed, so you need a product that is geared towards grassy weeds and not broadleaf weeds. We want to be clear that bermuda can be suppressed, but it is VERY difficult to kill completely. It will take multiple treatments to finally kill it. But Fusilade II is usually the go to product for this issue.
This is directly off of the product label:
Apply 0.07-0.14 oz/1000 sq. ft. (3-6 oz./A) along with 0.25% v/v (1/2 pt./25 gals.) of a nonionic surfactant. Application should be made every 28 days when the grass weeds are actively growing. The higher rates may result in temporary discolorization of the desirable turf with recovery in 10-14 days. Do not apply to desirable turf which is under stress. For best results, make applications in spring and fall and avoid treatments during July and August.
Complete control of undesirable grass may take 1-2 growing seasons.
We also recommend calling your local county extension office as they usually know the optimum times for spraying lawns in your area.
Fertilome Over the Top II is specially designed to kill grasses and grasses only and can be sprayed over the top of ground covers, flowers and ornamentals without harming them.
Fertilome Over the Top II Grass Killer per manufacturer is safe to use around Christmas Trees. Be sure to review the product label before application.
Fertilome Over the Top II Grass Killer is not labeled to treat for Cheat Grass. A better option would be Grass Out Max.
Actually neither the product label for the Hi-Yield Grass Killer or the Southern Ag Vantage Grass give instructions for using on a turf. Hi Yield states on the product label that only Red Fescue, Chewings Fescue, Hard Fescue, and Dichondra Turfs are also tolerant to this product. Both the Hi-Yield version and the Fertilome Over the Top II Grass Killer are meant to be used over the top of vegetables, gardens, trees, shrubs, ornamentals and ground covers only. Products should be used as directed on their respective product label and we would not advise of off label applications.
