Give Your Garden A Boost With Coffee Grounds

If you love coffee and love your garden, then you may have considered combining the two. Opinion on whether coffee grounds can help or hinder your garden is split. We take a look at the pros and cons, and how you can best utilise your used coffee grounds to make your garden flourish.

If you love coffee and love your garden, then you may have considered combining the two. Opinion on whether coffee grounds can help or hinder your garden is split. We take a look at the pros and cons, and how you can best utilise your used coffee grounds to make your garden flourish.

As compost

If you have a compost pile or bin in your garden, adding coffee grounds will add an array of nutrients. The grounds contain 1.45 nitrogen as well as calcium, magnesium and potassium, so they will help make your compost especially nutritious for your garden. It is important that you produce a balanced compost to ensure that it breaks down sufficiently, without smelling. The recommended ratio is 2-3 parts brown (leaves, paper, card etc) to one part green waste (food waste, grass clippings, coffee grounds etc).

As fertiliser

Worries that coffee grounds are acidic can be set aside; they actually have a near neutral pH. Coffee grounds make a good fertiliser either sprinkled on the top or layered into the first inch or so of the soil to provide a nitrogen boost. Alternatively, you can soak the grounds in water overnight and use the resulting brew as a liquid fertiliser.

As pest control

Four-legged and no-legged pests are reported to hate coffee grounds. Slugs and snails struggle to navigate the abrasive barrier and cats apparently detest the smell. Theoretically, a ring of coffee grounds around susceptible plants will keep these uninvited guests away.

As worm feed

Just like humans, worms are caffeine lovers. If you have a worm bin, add a modest amount of coffee each week - be wary of the mild acidity and don’t add too much. Even if you don’t have a worm bin, adding coffee to your soil will encourage worms in your garden.

As a pH reducer

Unused coffee has a pH of around 5, coffee grounds are probably more like 6. If you have acid-loving plants such as lily of the valley, blueberries, carrots, hydrangeas, and rhododendrons, they may well benefit from a nice cup of fresh coffee! Be aware that tomatoes react badly to coffee, so avoid using it if you have tomatoes growing nearby.

As always, there are some counter arguments to the use of coffee grounds in your garden. Some studies showed poorer growth when coffee grounds are used. If in doubt, go cautiously; if you have ten runner bean plants that are being attacked by slugs and snails, give one a protective barrier and see how it fares before liberally covering the rest.

A professional or experienced gardener will be able to call upon years of experience on the ground (literally). If you want to give your garden the very best start, it may be worth getting a gardener in.

Looking for more landscaping & gardening advice?

Find clear, practical answers to common landscaping & gardening questions, helping homeowners understand everyday issues, know what checks they can carry out safely, and when it is best to contact a qualified professional.

  • Do I need a professional to design and landscape my garden?

    For simple stuff - planting, basic lawn care, a few raised beds - you can often manage it yourself. For anything involving hard landscaping, drainage, retaining walls, or changing ground levels, get a professional involved.

    Badly built retaining walls and poor drainage cause expensive problems. A landscaper will also know which materials will actually work for your soil and conditions.

  • What is the difference between a landscaper and a gardener?

    A gardener looks after your garden on an ongoing basis - mowing, pruning, planting, general upkeep. A landscaper creates the garden in the first place - patios, paths, fencing, decking, drainage, planting schemes, the whole structure. Some people do both, but they're distinct skill sets.

    If you want the garden transformed rather than maintained, a landscaper is who you need.

  • How do I get rid of an overgrown garden?

    It's often more work than it looks. Beyond cutting things back, there may be significant root systems to clear, possibly invasive species to deal with (Japanese knotweed needs specialist handling), and ground prep before any replanting can happen.

    For anything seriously overgrown, professional clearance is going to be faster, more thorough, and safer than tackling it yourself.

  • What time of year is best for garden landscaping work?

    Hard landscaping - patios, paths, decking, fencing - can happen most of the year, though very wet or frozen ground causes delays. Planting is best in spring or autumn when things establish more easily.

    If you're planning something big, book a landscaper in late winter for spring work - good ones fill up fast once the season gets going.

  • What should I do if I have Japanese knotweed in my garden?

    Take it seriously. It can damage buildings and hard surfaces, and some mortgage lenders won't lend on properties where it's present and unmanaged. You're not legally required to remove it as long as it stays within your boundary, but you are responsible for stopping it from spreading to neighbouring land.

    It needs specialist treatment - either chemical treatment over multiple growing seasons, or excavation and licensed disposal. Don't compost it or put it in your general garden waste.

  • What are the benefits of artificial grass?

    The obvious one: no mowing. It stays looking decent all year and doesn't turn to mud in winter, which is a real plus for households with kids or dogs. Modern artificial grass is much more realistic than it used to be and holds its colour well. Worth knowing though: it gets noticeably hot in direct sun, needs occasional brushing, and is made from plastic that can't currently be recycled at end of life.

    It's a great fit for a low-maintenance, practical space - less so if the environmental benefits of a real lawn matter to you.

  • How can I make my garden low-maintenance?

    Cut down the amount of lawn first - it needs more regular attention than almost anything else. Swapping sections for hard landscaping or planted beds with ground-cover plants makes a real difference.

    Pick plants that suit your soil and aspect - ones that are happy where they are will largely look after themselves once established.

    A thick bark mulch layer keeps weeds down and holds moisture. A drip irrigation system on a timer removes another regular task. A good landscaper can design a scheme specifically around low maintenance rather than just what looks attractive.

  • Do I need planning permission for decking, a pergola, or a garden room?

    Decking is usually fine under Permitted Development as long as it's no more than 30cm above ground and doesn't cover more than half the garden. Open pergolas are generally okay - but start enclosing them with a roof and sides and they get treated differently.

    Garden rooms are classed as outbuildings: permitted if single-storey, within size limits, not used as living accommodation, and set back properly from boundaries. Listed buildings are a different matter - any structure nearby needs listed building consent. If you're not sure, a quick inquiry to your local planning authority will give you a clear answer before you spend anything.
