![]() ![]() The leaf tissues will collapse very rapidly after treatment. A brief exposure to the flame will heat the water inside the plant without flames. When using a flame weeder you do not need to actually burn the weeds. Sites where flame weeding may be practical include cracks in driveways, between pavers, or in gravel mulch. ![]() Flame weeding is effective on seedling broadleaf weeds growing in hardscapes but should not be used in areas where flammable mulching materials are present. The limitations, of course, include the expense and availability of labor to do so. Hand weeding frequently is effective for annual weeds but can also control perennial weeds before they become well established. ![]() This is best accomplished with frequent weeding – about every 2 weeks. Remove weeds before they have a chance to establish a large root system and before they go to seed. There will always be some hand weeding in landscape plantings. These weeds will need to be controlled, manually or with postemergence herbicides, before they go to seed. However, even in the best-managed landscapes, some weeds will germinate and establish. Preemergence herbicides may be used to control annual grasses and small-seeded broadleaf weeds. The best alternative is to prevent the weeds from emerging by using mulches and sanitation practices that prevent the introduction and spread of weed seeds. Many options are available to control small broadleaf weeds. ** for more on the toxicology debate, visit our fact sheet on glyphosateĬontrolling Seedling Annual Broadleaf Weeds Without Glyphosate Skip to Controlling Seedling Annual Broadleaf Weeds Without Glyphosate This will result from higher chemical costs, more applications, or higher labor costs. Regardless of the method or product chosen, the cost for removal will be higher than with glyphosate. Perennial weeds, established annual weeds, and grasses are more difficult to control. Seedling annual broadleaf weeds can be easily controlled with other herbicides and herbicidally-active natural products, or even with a hoe or other tool. The question many are asking is: “what can I use instead of glyphosate?” The answer to this question will depend upon the weeds you are trying to control. However, recently the toxicity and environmental safety of glyphosate has been questioned**, And, though the US Environmental Protection Agency continues to maintain that glyphosate does not pose a threat to human health or the environment when used according to directions, many agencies and individuals would prefer an alternative.
