To suppress the spread of prickers in your lawn, you can either use organic or chemical-based solutions. Removal timing, weather, and soil type can affect pricker removal effectiveness.
If you're eco-conscious, there are natural ways to remove prickers. You can do it manually using a garden tool, gloves, and patience. You can also use salt and baking soda mixture or apple cider vinegar to dehydrate the weeds. Dispose of the weeds after removing or apply remedies until they die.
Apply a pre-emergent herbicide before seed development in soil temperatures above 52°F. For Texas, apply herbicide on April 1 or March 1 in southern areas and reapply every six weeks until September. Use post-emergent herbicides like MMSA and DMSA if prickers persist.
Herbicides are a last resort for prickers. Pre- and post-emergent herbicides are recommended. Selective types won't harm grass, while non-selective herbicides kill all plants. Pre-emergent types prevent grass growth longer. Before buying herbicide, read the label or ask NPIC.
Healthy and dense grass can prevent the growth of prickers on your lawn. Ensure that your grass is well-fed with fertilizer and receives enough water every week. Mowing the grass slightly higher can also block the sunlight from the weeds.
