You say it is a new home for you. Have you been there long enough for glyphosate to work? The weather has only warmed up recently. It is no use applying it unless the weed is actively growing. It then takes some time to work. Not days.
Do not use the stuff you get in garden shops or centres. You need agricultural Roundup. Expensive, but if you have a bad infestation it will be an investment. Ensure you dilute it according to instructiions, and give it time to work.
