|we have a problem with sandburs. our sod lawn in the back yard ends 40ft. out from the house, which is where the property line ends. however there is a right of way that we maintain(mow) that was never seeded or covered with sod, another 30ft. farther back to the canal . all that is growing there are sand burs. our dogs won't even venture out there. what can we do to rid ourselves of this problem, short of putting sod down on property that is not realy ours?
There are sprays that prevent the sandburs from sprouting and growing into plants. These preemergence products must be applied before the plants emerge in the early spring. Your County Extension Office can suggest specific products and timing of applications. There are also postemergence weed killers that are either general killers or selective for grasses.
The only other approach is to water and fertlize the area as grassburs thrive in poor, droughty, sandy soils. Then you would need to mow it regularly too. Probably not a good option.
Thanks for the question. Please stop in again soon!
