Do not use residual path and patio weedkillers on paths or drives close to beds or lawns or tree root runs as this can leach Spraying in the evening will be far more effective than spraying during the day as more of the chemical will be absorbed by the foliage Around low-growing shrubs and perennials shield the cultivated plants from the spray until it has dried on the weed Removing horsetail by hand is difficult. Although rhizomes growing near the surface can be forked out, deeper roots will require a lot of excavation. Shallow, occasional weeding is not effective and can make the problem worse, as the plant can regrow from any small pieces left behind. However, removing shoots as soon as they appear above the ground can reduce infestation if carried out over a number of years. Unfortunately, whenwild garlic or crow garlic are found growing amongst other bulbous plants no weedkiller will kill them without also harming or destroying the cultivated plants by absorption through their leaves and roots.

Weed killers are every gardener’s friend. While some of us are better than others at growing shrubs and plants, all of us seem to be able to “grow weeds”. Thankfully, you can rid your lawn, patio, gravel drive, paths, and vegetable patches of these nuisance visitors using a range of highly effective and fast-acting weed-killer products. Tough weedkillers containing glyphosate (e.g. Roundup Tree Stump & Rootkiller, SBM Job Done Tough Weedkiller (soluble sachets only), Doff Maxi Strength Glyphosate Weedkiller or Westland Resolva Xtra Tough Concentrate or for spot treatment use Roundup Gel) can be applied in late summer when growth is strong. Before using, bruise the shoots with a rake to ensure effective penetration The mention of any product, supplier or service does not constitute an endorsement by the Society.

STEP 3: Into each pot sow four broad bean seeds or insert four tomato cuttings (use sideshoots from healthy tomato plants). Water well with clean water. If you suspect a problem with a particular batch of peat-free or peat-reduced compost or manureit is possible to do a simple test for weedkiller residues. This involves germinating plants that are sensitive to herbicide such as tomatoes or beans. How to do thetest

On vacant soil, where there are no herbaceous perennials, bulbs or crops, you can use SBM Job Done Path Weedkiller (ready to use only) and Weedol Pathclear products containing glyphosate/diflufenican to inhibit new shoots Established ground elder can be controlled by spraying with a tough weedkiller containing glyphosate (e.g. Roundup Stump Killer,Doff Weedout Extra Tough Weedkiller or Westland Resolva Pro Xtra Tough Weedkiller) STEP 2: Fill another two clean pots with another brand of growing media or John Innes potting compost as a control (i.e. a standard to compare to) and label.Attempting to dig out the plants often assists their spread as, unless great care is taken, this operation will distribute the tubercles (small tubers). Dig out tubers and young plants before flowering but this may need to be repeated over several seasons Apply the spray in mid-summer when there is lots of leafy growth, then reapply if necessary later in summer

There are many other advantages to using weed killers. For example, you can control what weeds and plants are removed by targeting where you spray and ensuring that any plants that you wish to stay put are not harmed by any chemicals. Removing weeds also allows nearby plants and shrubs to retain much-needed nutrients in the soil, resulting in improved growth and bigger blooms. B&Q sells many types of weed killers, including handy spray bottles, concentrated formulas, and power pump products. The use of bleach or salt to kill weeds on paths and drives is strongly discouraged, as this can cause pollution and damage plants.
