Is Free or homemade weedkiller effective?
When and where should I spray? Glyphosate at a concentration of 360g/litre is a powerful herbicide which works very efficiently in all areas including gardens. Points to note are: • When spraying around roses and other plants please make sure you do NOT get spray onto the foliage of desirable plants as it will destroy them. This is a NON-selective herbicide. • You can spray an area BEFORE cultivating as well as straight after sowing when the seeds have not yet germinated. This is not a PRE-EMERGENCE spray and will only effect plant tissue through absorption. • Re-seeding of lawns can be done by spraying of the old lawn, leaving it for a week, and then re-sowing with new grass seed. This gives the spray time to act. • Some weeds are harder to kill than others. Brambles and thistles at early stages of development will need a much higher concentration of spray than grasses. This can be either by spraying longer or by spraying with a higher concentration. • Adding detergent like washing up
