Resolva Weed Killer Reviews

4.4 out of 5 · Based on 20,000+ verified reviews

After reading some of the reviews my mind was a little muddled on this weedkiller. But at the same time, it has the best reviews out of all the weedkillers available on Amazon. Some people have said that it doesn't quite take 24 hours to see it starting to work, but it honestly did for me. I would highly recommend that you read all the instructions to get the best results. I personally used it at the beginning of the evening on a dry day and checked the weather for the next couple of days to ensure no rain was forecast as this will undo your hard work. I'm pretty sure the cooler condition of the night helped for the weedkiller to take grip of those weeds. The 3 Litre does go very quickly but it really is effective. By the next morning the weeds had began to shrivel and wilt. Not brown which I think everyone is expecting but within a day or 2 they all turned brown and died off. I left it for another week just to make sure they were really dead and lifted them all up and HAVEN'T re-grown since! Couldn't believe my eyes! Result! I like that the trigger spray has 2 different sprays. A fine mist for larger areas/ more troublesome weeds and a more concentrated 'power' spray - I personally used that one for a more concentrated spray on my very stubborn weeds. Now with all the mixed weather, the weeds in my garden have went into over drive. And now I have found something that actually works! I will be buying some more do finish the rest of the garden off. Bottom line - works, read all instructions to get best results and watch those weeds die!

Worked really well on the weeds in my garden. So far they have not shown any signs of regrowth.

Needed something to spot weedkill around patio, path and driveway and this has been the perfect answer. First used for a comprehensive spray around the problem areas and 99% of the weeds had died off within 3-4 days, including dandelions. The connected spray nozzle is great - lets you choose between a direct spray for individual weeds or a wider spray for larger patches of weeds. It now sits in an easily accessible spot in my shed and means I can quickly tackle any pesky weeds that rear their heads. Very simple to use and no mess - perfect!

This may well be my favourite weed killer. I have so many random weeds and plants growing around my garden I spray it in-between the patio, on a random climbing plant and a mud patch near the fence and this keeps those pesky weeds at bay. It's sprays well and has two different concentration one more direct, one abit wider and doesn't seem to leak. It advised not to use on your grass. My garden is more weeds than grass but I obey. I do spray on the really thick weeds and it does seem to keep them at bay. Decent size, decent price.

A very effective weedkiller - particularly for the more stubborn ones such as brambles. It's easy to use and apply but be sure to wear protective gloves and glasses. You can either spray direct from the bottle or, as I do, decant some into a garden sprayer - this has a spray extension so I can reach otherwise unaccessible areas. I find it best to apply it at dusk so it doesn't dry out immediately. Avoid over spraying particularly during windy periods as this stuff will kill everything it touches. Give your sprayer a good clean after use. I have also used this weedkiller in its more cost effective "sachets" guise - which need to be mixed with water. Both types are equally as effective. This ready to use form is easier to use and it's potentially less messy. I suppose, it's horses for courses! Reasonably priced and quick delivery.

I was very unsure of this product at first, thinking it would kill the grass as well. But I thought I would give it a go. So tried it on a small patch of the Lawn where the weeds appear to be growing and taking over. Few days past and I could see the product was starting to work the weeds were turning brown but the grass remained unharmed. So tried the next patch and same thing. In time I will go back to the first patch and start to re seed and hopefully get my lawn back to looking lush. Arrived well packaged and no leaks. On looking at the bottle I still have quite a bit left as you don't have to use loads. However to do the whole lawn I might need another bottle I shall see how it goes.

Part of the Westland Horticulture portfolio, Resolva sits within a wider family of respected gardening brands known across the UK. Westland has built its reputation over more than 30 years by developing products that help gardeners achieve reliable results season after season.

Tackling the Most Persistent Garden Challenge

Left untreated, weeds compete with plants for light, space, water and nutrients, and can quickly spread if allowed to establish. The brand has been developed to offer effective solutions for different situations, whether the goal is clearing weeds from hard surfaces, tackling tougher growth in problem areas or managing broad-leaved weeds in lawns without harming the grass when the correct product is used.

Convenience and Performance

The Resolva range is built around convenience as well as performance. Ready to use sprays make spot treatment simple, while concentrate formats provide flexibility for larger jobs. Products such as Resolva Pro Xtra Tough Weedkiller Ready to Use, Resolva Path & Drive Ready to Use Weedkiller and Resolva Lawn Weedkiller Extra Ready to Use help cover a range of garden needs. This allows gardeners to choose the right solution for the right area rather than relying on a one size fits all approach.

The idea behind Resolva is simple — effective weed control should be straightforward, accessible and suited to real gardens. Whether maintaining a neat patio, keeping driveways clear, protecting the appearance of borders and open spaces or improving the condition of a lawn, the brand offers practical solutions backed by the expertise of one of the UK’s leading horticultural groups.

Frequently Asked Questions

Resolva is a garden weed control brand offering practical solutions for common weed problems around the home. The range includes products for paths, patios, driveways, open areas and lawns, with options designed for different types of weeds and different styles of application.

Resolva is part of Westland Horticulture, a well-established name in the UK gardening market. Westland manages a portfolio of trusted garden brands and has built a strong reputation over more than 30 years for helping gardeners achieve reliable results.

The range includes ready to use weedkillers, concentrates for mixing with water, tough weed control products, path and driveway treatments, and selective lawn weedkillers. This gives gardeners a choice of solutions depending on where the weeds are growing and how they prefer to treat them.

Products such as Resolva Xtra Fast Weedkiller and Resolva Path & Drive Ready to Use Weedkiller are designed for use on hard surfaces where weeds commonly appear. These products are intended to help keep paths, patios and driveways clean, tidy and easier to maintain.

Only lawn-specific products in the range should be used on grass. A product such as Resolva Lawn Weedkiller Extra Ready To Use is intended for lawn use, while non-selective weedkillers such as Resolva Xtra Fast can damage or kill grass and should not be sprayed onto lawns.

Resolva Xtra Fast Weedkiller is designed for fast visible action. It is a glyphosate free formula that works by contact action on exposed green parts of the plant, making it a popular option for gardeners looking for a quick and effective treatment for weeds on hard surfaces and open areas.

Resolva Xtra Fast contains pelargonic acid. This is a naturally occurring fatty acid found as esters in the oil of pelargonium, commonly known as geraniums.

Some products in the range, including Resolva Xtra Fast Weedkiller, are glyphosate free. This makes them a suitable option for gardeners who prefer an alternative approach while still wanting effective visible results.

Visible effects can often be seen within hours on directly treated green growth when using fast acting products such as Resolva Xtra Fast. Full results can vary depending on the type of weed, weather conditions and the maturity of the plant.

Not always. Annual weeds and younger growth may respond quickly, while larger, tougher or perennial weeds may need repeat treatment. Woody parts of plants are not usually affected by contact weedkillers, so persistent weeds can require follow-up applications.

For best results, weedkiller should be applied during the active growing season when weeds are healthy and growing. Calm, dry conditions are usually preferred, and treatment is generally more effective when temperatures are mild to warm and rain is not expected shortly after application.

Different garden areas need different treatments. Hard surface weedkillers are designed for places such as patios and driveways, while lawn weedkillers are formulated for use on grass. Using the correct product helps improve results and reduces the risk of damaging wanted plants.

No. The range is designed for everyday gardeners as well as more experienced users. With convenient ready to use formats and straightforward concentrate options, Resolva products are made to be accessible for anyone looking to keep their garden under control.

Westland Horticulture focuses on helping people succeed in the garden, whether they have a large outdoor space or a small area at home. The company also places strong emphasis on sustainability, including peat reduction, renewable energy use, local sourcing initiatives and a zero-waste-to-landfill approach across its sites.

Gardeners choose Resolva because the brand combines practical performance with ease of use. The range is built to tackle real garden weed problems with targeted products, fast acting solutions and the backing of an established UK horticultural company.
