Frequently Asked Questions (FAQs)
1. How do you kill weeds in Southern grass?
For killing weeds in Southern grass, Roundup For Lawns4 is a recommended option. It is a tough weed killer specifically designed for Southern grasses. This product effectively eliminates 93 types of weeds, including dollarweed, dandelion, clover, and yellow nutsedge, while preserving the health of the grass.
2. What weed killer kills everything but grass?
SedgeHammer® Herbicide is a suitable weed killer that targets nutsedge weeds without harming the grass. It comes in a Water Dispersible Granule (WDG) form and needs to be mixed with water for application. While it may take up to 21 days to show results, it is an effective option for controlling nutsedge without damaging the grass.
3. Is bleach or vinegar better for weeds?
Bleach is a potent weed killer that can effectively eliminate mature weeds and prevent new ones from growing. Unlike vinegar, bleach remains in the soil, providing longer-lasting weed control. However, it's important to note that bleach is a more noxious substance compared to vinegar.
4. Does vinegar kill weeds permanently?
Vinegar, being acidic, can kill most broadleaf weeds. However, it primarily affects the leaves and may not reach the root system, leading to potential regrowth. For more long-lasting results, a mixture of 1 cup of table salt with 1 gallon of vinegar can be used, as the salt helps dry out the weed's root system.
5. What kills weeds permanently but not grass?
To kill weeds permanently without harming grass, it is recommended to use a selective herbicide. Selective herbicides target specific weeds while leaving the grass unharmed. It is important to carefully read and follow product labels to ensure proper usage. Non-selective herbicides, on the other hand, can kill any plant they come in contact with, including grass.
6. How do I permanently get rid of weeds in my gravel driveway?
Rock salt can be an effective and natural weed killer for gravel driveways. Simply sprinkle rock salt on the areas with weeds, and over time, it will kill them. However, it's important to note that rock salt can also harm nearby plants, so it should be used with caution and only in areas where you want to eliminate vegetation.
