Lush green grass growing in a lawn is undeniably lovely, but the same grass creeping into your flower beds can be one of the most stubborn weeds you encounter. In addition to perennial turf grasses that can escape lawns and invade gardens, there are several weedy annual and perennial grasses, such as crabgrass, that can be ongoing enemies for a gardener. Weed grasses require special attention to eradicate from the garden, especially so you don't harm nearby flowers or shrubs.


Preventing Grass in Flower Beds


You can try to kill grass in flower beds, but if you can keep grass out of unwanted areas in the first place, your job becomes much easier. If you’ve ever tried pulling grass out by the roots and getting every last bit out, then you know it’s not just difficult but nearly impossible. One good strategy for prevention is to use a barrier between beds and the lawn. Landscaping bricks or plastic barriers that you sink a few inches into the ground can really help keep grass at bay. Keep an eye on the edges and pull any grass you see creeping its way into the bed.


Are Herbicides the Only Way to Make Grass Go Away?



While there are specially formulated herbicides that can kill only the grass that is ruining your garden without affecting your plants, most people are leery of the safety of chemicals.


Not only are they worried about losing their flowers but they don’t want to expose chemicals to small children and animals that frequent the outdoors.


If you are interested in using an herbicide make sure you check it out thoroughly before applying it to your flower bed. Do research online, check reactions from other gardeners, and talk to a knowledgeable person at your local gardening center who can guide you in the right direction.


Using Boiling Water in Your Flower Beds



Boiling water is very effective at killing grass and weeds, and it’s pretty effortless too! Here’s how: 

Boil water and pour it onto the grass that you want to kill. This method is indiscriminate, so don’t let the boiling water touch any other plants.



Watch the grass, as it should turn yellow and die.



The roots may be unaffected with just one round of boiling water, so repeat this process two days after the initial treatment.
