Hello Sir
All weeds can be controlled without weedkillers, but persistent or deep rooted weeds may be very difficult to eradicate. Ongoing control is likely to be necessary.
Follow the below steps:
Hoeing: For maximum effectiveness, choose a dry day with a light wind, so that the seedlings will dry out on the surface of the bed rather than re-rooting into moist soil.
Hand-pulling or hand-weeding with a fork: Perennial weeds should be dug out with as much root as possible, using a hand or border fork. Hand weeding is easiest on lighter soils and should only be attempted where it will not disturb the roots of garden plants. Further pulling may be necessary with persistent weeds such as bindweed or couch grass where small root sections left behind can re-grow into new plants.
Weed knife and other weeding tools: A weed knife has a hooked end and is a useful tool for weeding between paving slabs and along path edging.
Repeated cutting: In large weedy areas, repeated cutting to ground level over several years will weaken and even kill some weeds. This is usually done with a strimmer or sickle-type weeder.
