Depart the leaves is the brand new gardening mantra.
It instantly appeals to me greater than getting out a leaf blower or rake, bagging up leaves and discovering someplace to retailer them whereas they break down into leaf mould. (By no means thoughts truly placing them in a automobile and taking them to the native dump!)
Raking leaves was essentially the most boring activity of my childhood. My mom ushered us all out for hours of back-breaking tedium.
But at the moment’s ‘depart the leaves’ marketing campaign on social media means that a lot of this work was pointless. Others counsel, nevertheless, that leaving the leaves may injury your backyard and even your well being.
Having left leaves alone borders for 15+ years with no ill-effects, I’ve finished some extra analysis to see the place we will depart the leaves and the place they’d be higher swept up.
That is my central border. I’ve by no means cleared any leaves away. Most of them rot down by the spring, though a number of are blown onto the garden on dry, windy days.
Can you allow the leaves on borders?
You’ll be able to depart leaves on most borders with none downside. They are going to break down over the winter and by spring, you’ll hardly discover them.
As they break down, they’ll return diet to the soil.
Piles of leaves additionally supply habitats to wildlife. Folks have identified – appropriately – that this contains slugs and snails. But it surely additionally contains slug and snail predators, akin to hedgehogs, frogs, toads, slow-worms and floor beetles.
There are solely two potential issues with leaving leaves on borders.
Firstly, some timber have very thick, huge leaves that take a very long time to interrupt down. The leaves from my Magnolia grandiflora can cowl smaller vegetation, akin to Saxifrage ‘London Delight’. This could deprive them of sunshine, so I do push them off (after I discover).
The highest photograph is my central border in autumn 2022. The image under it reveals that the leaves have decomposed round 3 months later. I did see a number of traces of leaf after I went actually shut up, nevertheless it wasn’t an issue.
Do leaves blow across the backyard should you depart them?
Many individuals see leaves blowing round a metropolis avenue. They assume that leaves on borders will blow across the backyard in the identical approach. However, principally, they don’t.
I’ve examined this in my very own backyard over many winters. (Once I discover leaves on the garden, I can inform the place they’ve come from in keeping with what sort they’re!)
I’ve by no means recognized leaves blow off borders if the leaves are on the again, proper subsequent to a wall or fence. The wind can’t get behind them to blow them round. I’ve even left fairly a excessive pile of leaves in the back of a border and it has stayed there, steadily breaking down.
Nonetheless, in case your border is in the course of the backyard, it’s a lot simpler for leaves to blow round the remainder of the backyard. If in case you have a moist autumn, they’ll principally keep the place they fall, however in dry, sunny climate you’ll get some leaves blowing across the garden, paths or terraces. Not all of the leaves will blow round, however some will.
Can leaves be used as mulch?
Sure, leaves make a wonderful mulch.
There are two faculties of thought. There are those that depart the leaves in borders and even sweep leaves from the garden instantly into borders.
And there are those that advise chopping the leaves up first.
Both is okay (aside from these huge thick leaves, which do want chopping up). The chopped-up leaves will decompose extra shortly and are much less more likely to blow round.
Can leaves be added to the backyard compost bin?
Sure. I’ve typically added leaves to the backyard compost bin. They don’t decompose as shortly as many backyard clippings or uncooked fruit and veg, however that doesn’t must matter.
Except you’re sieving your backyard compost to plant seeds, then having some partially composted ingredient isn’t an issue. You’ll be able to unfold compost on the backyard even when it’s not fully damaged down.
Nonetheless, one efficient approach of including leaves to the compost is to mow the leaves on the garden. Then throw the combined bag of garden clippings and chopped up leaves into the compost bin. It’s an ideal combine and can break down shortly.
Right here’s a very easy information to creating your individual backyard compost.
You can even bag up leaves individually to make leaf mould. This can be a splendidly nutritious mulch in your backyard borders, however I’ve discovered that leaves appear to decompose rather more slowly after they’re all bagged up collectively.
If you will bag up leaves, make certain they’re moist and tear air holes within the luggage. They are going to take not less than 1-2 years to interrupt down.
Can you allow leaves on lawns?
This query causes a whole lot of arguments. Having checked out a lot of them, I can summarise it.
If in case you have a lot of leaves, which lie in a thick layer in your garden, then it is going to take them months to interrupt down. In that point, your garden can be disadvantaged of daylight. This may occasionally trigger naked patches, particularly when you’ve got a lot of the thicker, extra leathery leaves.
Nonetheless, should you solely have a scattering of leaves over your garden, then they’ll break down naturally, including diet to the garden.
The simplest technique to cope with leaves on the garden is to run a mower over them. Use the next setting than you’d in summer season when the grass is rising strongly.
You’ll be able to both throw the leaves and garden clippings into the compost bin, throw it into the borders as a mulch or depart the chopped up leaves the place they’re on the garden. They’ll break up extra shortly than entire leaves will.
In america, the place most of the garden grasses aren’t native, this debate typically veers off into the ‘lawns are unhealthy’ argument.
It’s necessary to keep in mind that there’s a distinction between sustaining a non-native garden in an space that isn’t appropriate for lawns and having a primarily native garden within the UK, the place lawns deplete comparatively few assets and are each sustainable and wildlife-friendly.

Will the leaves trigger unhealthy moulds after they rot down?
Nature doesn’t rake up leaves. It permits them to rot down, returning their diet to the soil.
Leaves rot down on a forest flooring all 12 months spherical. Forests and woods don’t odor unhealthy. And folks aren’t normally warned in opposition to strolling in them due to ‘unhealthy moulds.’
However should you search whether or not leaves trigger unhealthy moulds (molds) on-line, you will see that lots of of warnings, virtually all from america, on the hazards.
Actually moulds, funghi and fallen leaves are an element within the autumn. These can set off allergic reactions, just like these from pollen in summer season. A number of of those allergic reactions and reactions might be extreme.
However I discover it odd that persons are rather more involved about this in america than they’re within the UK.
Are our fallen leaves much less more likely to trigger allergic reactions? Or do some international locations fear extra about leaves than others?
This may occasionally even be a quantity challenge. Should you’ve bought one or two timber of various sorts in your backyard, then you definitely received’t have an enormous variety of leaves at anybody time. But when your property is surrounded by lots of of the identical deciduous timber all shedding their leaves without delay, then leaves will take longer to interrupt down. The funghi that assist break them down could also be round longer.
It could even be value noting that nature doesn’t sweep leaves into an enormous pile, so maybe the stability of funghi and moulds could also be totally different if leaves are in piles slightly than merely left.
And never all ‘moulds’ are unhealthy…
You’re definitely extra more likely to see funghi in autumn, when leaves are falling, however this doesn’t imply that leaving leaves causes all of them. Or that they’re essentially unhealthy.
The Royal Horticultural Society says that almost all varieties of funghi are superb for gardens, serving to vegetation to take up vitamins and useless matter to decompose.
Their newest Wildlife backyard at RHS Wisley has areas the place funghi have intentionally been planted.
There’s extra from the RHS about adopting a extra relaxed perspective to gardening in gardening for biodiversity.
There are a number of damaging funghi, akin to honey fungus and verticilium wilt. However sweeping up your leaves isn’t more likely to make a whole lot of distinction to them, in some way.
However, as with every thing, I feel it’s value taking a person method to this. Is there any scientific analysis finished in your space? Have you ever – or your loved ones – personally skilled issues with leaves within the autumn? What’s proper for one particular person isn’t essentially proper for an additional, and should you do get well being points in autumn, it’s necessary to deal with them.
These funghi have been intentionally launched into the Wildlife Backyard at RHS Wisley.
Are fallen leaves toxic to canine (or different pets)?
As I mentioned in Tips on how to Pet-Proof Your Backyard, about 25% of any backyard is more likely to be poisonous to each people and pets. However most people and pets don’t eat the vegetation.
Plant poisoning is comparatively uncommon, however it’s important to maintain an in depth eye on puppies, kittens and toddlers in a backyard as a normal security measure. You by no means know what they’re going to place of their mouths or what different hurt they might do to themselves.
The PDSA within the US (Folks’s Dispensary For Sick Animals) says that useless leaves are much less more likely to trigger issues that inexperienced leaves.
There are a number of vegetation that are very poisonous, akin to oleander or ricinus. I personally don’t develop both for that motive. However you will note oleander throughout Europe, with a lot of cats and canine sunning themselves in entrance of the bushes.
I’d counsel asking your native vet if there are vegetation in your space that appear to trigger issues with canine or cats consuming the leaves.
Should you get a obscure, normal reply, that most likely means the vet can’t bear in mind particular instances (so there most likely are few or none). In case your vet has handled poisonings as a result of pets consuming fallen leaves or particular vegetation, they’ll say so fairly clearly.
Can you allow leaves on paths?
Don’t depart the leaves on paths or locations the place you stroll. It makes them slippy in wet or icy climate.
However you don’t must take the leaves very far. I simply scoop mine up with leaf scoopers (I at present use these Straeme leaf grabbers) and deposit them within the nearest border (on the again, by the wall!)
Notice that hyperlinks to Amazon are affiliate, see disclosure.
Paths and terraces might be slippy if they’re coated in moist or frozen leaves. A pal of mine says she has additionally slipped whereas strolling on her garden, so that’s one other issue to consider.
Can leaves develop roots?
Leaves can’t regenerate or develop roots. You received’t discover a lot of tree seedlings popping up since you depart leaves in your borders or garden.
Some other issues?
There’s a fantastic Instagrammer Alexis Nicole who says in her video: ‘depart the leaves. They received’t break into your own home and steal all of your wine.’
How refreshing to seek out one thing we will all agree on. I feel we will safely say that’s true for wherever you reside.
The ‘depart the leaves’ marketing campaign is all a part of gardening to help wildlife. It additionally saves time, effort (and even just a little cash) for the gardener, so this one is a ‘win/win!’
However, as with every thing, there’s no ‘one dimension matches all’ recommendation in gardening. Should you’re reluctant that it will be just right for you, maybe strive leaving leaves on one border and see what occurs.
Let me understand how you discover it.
