How do you kill the grass in your flower bed without killing the flowers?

Answer 1

Check with your local flower nursery. The product is call Preen I believe. It is made just for this but I think you have to use it in the spring. Ahh here it is:

Weeds germinate in the spring, summer, and fall. Preen Garden Weed Preventer should be used during each of these seasons to prevent weeds and can be reapplied every 8 to 12 weeks. The rate at which Preen Garden Weed Preventer biodegrades in the soil and loses its effectiveness will depend on temperature, soil type, and moisture conditions of the soil. Preen Garden Weed Preventer will need to be reapplied more often in hot, humid conditions.



If you have weeds in your garden, remove the weeds by pulling or hoeing them, or use an all-purpose weed killer of your choice.


Sprinkle Preen Garden Weed Preventer evenly over the soil surface at the rate of 1 oz. per 10 sq. ft., being sure to keep granules away from plant roots and foliage. It is critical to apply Preen Garden Weed Preventer at the correct rate and to uniformly spread it across the soil surface because weeds will grow if the Preen Garden Weed Preventer granule is underapplied in an area.
Apply Preen Garden Weed Preventer using the built-in applicator on the canister or a hand-operated spreader. If applying by hand, wear gloves.
Water or lightly rake the Preen Garden Weed Preventer granules into the top 1 to 2 inches of the soil. Preen Garden Weed Preventer will not be effective if it is too deep in the soil. Sunlight will cause the Preen Garden Weed Preventer chemical to photodegrade and lose its strength. If you choose to water Preen Garden Weed Preventer in, the active ingredient will be below the soil surface while the remaining particles may remain on the surface and will eventually disintegrate.
While Preen Garden Weed Preventer will not harm your plants if it comes in contact with them for a short period of time, always wash or brush off stray granules from plant foliage to minimize damage or discoloration that could be caused by long term direct contact with the Preen Garden Weed Preventer chemical.
Please note that Preen Garden Weed Preventer can stain porous surfaces such as concrete, stone, vinyl, flooring, clothing, and shoes if Preen Garden Weed Preventer is not swept off these surfaces or if Preen Garden Weed Preventer becomes wet on these surfaces.

Easy, just weed regularly. When I prepare my garden for shows I use a flat paint scraper (sturdy blade) to keep the edges of the lawn perfect at the same time I pull all grass runners out of the beds - if you do this fairly regularly it will pay off. The more expensive option is to place a barrier between the lawn and the beds. There are some really nice options and I would visit the larger nurseries to get prices and products. Please avoid any type of herbicide as you may damage your plants.

it's true: regular weeding is the best way. many people make the mistake of letting them go to seed before weeding. an ounce of prevention is worth a pound of cure here; if you always get to them before they go to seed, you will have that much less to contend with next time. and mulch. mulch is good for your plants and an excellent weed preventative in that it stops the seeds from getting to the soil.
