10 tips for efficient Weed Control

Weedkillers are most effective when the weeds are actively growing, usually between March and September.

1) Weedkillers are most effective when the weeds are actively growing, usually between March and September, when they have an increased surface area with which to absorb the treatment. It is advisable not to use Weedkillers during drought conditions, when weeds are not actively growing. During dry spells, water the area a day or two prior to applying a Weedkiller.

2) Use Weedkillers in still weather conditions to avoid spray drifting onto desirable plants. When using sprays near plants you want to keep, use a large piece of card to protect nearby plants, or cut the top and bottom off a large soft drinks container to form a cylinder over the weed, and spray down on to the encircled weed.

3) If you want to replant an area after clearing weeds, use a Weedkiller with a biodegradable formula that breaks down into natural materials within the soil, such 3 Hour Weedkiller or Glyphosate. These can even be used to clear the vegetable patch before planting or sowing.

4) Crush the stems of Horsetail before applying Weedkiller. This breaks down the waxy surface, helping the Weedkiller to penetrate more easily.

5) If climbing weeds have wound themselves round other plants in your garden, gently unwind the weed stems (taking care not to damage them) and then once they are in a heap on the ground, simply spray with a systemic Weedkiller such as Glyphosate. This ensures maximum coverage of the troublesome weed whilst minimising harm to desirable plants. Alternatively place canes close to weeds such as bindweed, and allow them to climb the canes before spraying.

6) Children and pets need not be excluded from treated areas once the product has dried. All Bayer Garden Weedkillers are registered for home garden use through the UK Regulatory Authority, and in order to achieve registration, they must be suitable to use in and around areas which children and pets may use.

7) For grazing pets e.g. guinea pigs, rabbits or tortoises, it is advisable to keep pets off the grass until the weeds have died. The effects of some Weedkillers can disrupt the distribution of sugars, making once unpalatable weeds palatable and vice versa.

8) Make sure you choose the best formulation and size for the job in hand. Ready to Use formulations are simple and convenient, no need to mix or measure. Choose the 1 litre hand held sprayer for small areas or to target specific weeds. For larger areas, concentrated formulations in pre-measured water soluble sachets are a clean, easy and economical solution when applied with a watering can or sprayer.


9) For best results on lawns, apply a selective Lawn Weedkiller when the soil is moist, during spring or early summer whilst the grass and weeds are actively growing. The most difficult lawn weeds have tiny leaves, so using as fine a spray as possible and allowing the weeds to grow out before treatment makes a big difference. Don't cut the lawn for a few days before and after treatment, to allow maximum penetration of the Weedkiller.

 10) A survey of osteopaths and gardeners discovered hand weeding to be a major cause of back strain. More than one in three gardeners surveyed had suffered from a weeding related 'bad back'. The advice from osteopaths is to kneel down first and use a weedkiller!
