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 really placing them in a automotive and taking them to the native dump!)
Raking leaves was essentially the most boring process of my childhood. My mom ushered us all out for hours of back-breaking tedium.
But in the present day’s ‘depart the leaves’ marketing campaign on social media means that a lot of this work was pointless. Others recommend, nonetheless, that leaving the leaves might injury your backyard and even your well being.
Having left leaves by myself borders for 15+ years with no ill-effects, I’ve performed some extra analysis to see the place we are able to depart the leaves and the place they might 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 just a few are blown onto the garden on dry, windy days.
Can you permit the leaves on borders?
You’ll be able to depart leaves on most borders with none drawback. 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 provide habitats to wildlife. Folks have identified – accurately – that this contains slugs and snails. However it 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, massive leaves that take a very long time to interrupt down. The leaves from my Magnolia grandiflora can cowl smaller crops, akin to Saxifrage ‘London Satisfaction’. This might deprive them of sunshine, so I do push them off (once I discover).
The highest picture is my central border in autumn 2022. The image under it reveals that the leaves have decomposed round 3 months later. I did see just a few traces of leaf once I went actually shut up, nevertheless it wasn’t an issue.
Do leaves blow across the backyard when you depart them?
Many individuals see leaves blowing round a metropolis road. They assume that leaves on borders will blow across the backyard in the identical means. However, largely, they don’t.
I’ve examined this in my very own backyard over many winters. (After I discover leaves on the garden, I can inform the place they’ve come from in keeping with what kind they’re!)
I’ve by no means identified 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 behind a border and it has stayed there, step by step breaking down.
Nonetheless, in case your border is in the midst of the backyard, it’s a lot simpler for leaves to blow round the remainder of the backyard. In case you have a moist autumn, they’ll largely keep the place they fall, however in dry, sunny climate you’re going to 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 colleges of thought. There are those that depart the leaves in borders and even sweep leaves from the garden straight into borders.
And there are those that advise chopping the leaves up first.
Both is ok (apart from these massive thick leaves, which do want chopping up). The chopped-up leaves will decompose extra rapidly and are much less more likely to blow round.
Can leaves be added to the backyard compost bin?
Sure. I’ve usually added leaves to the backyard compost bin. They don’t decompose as rapidly as many backyard clippings or uncooked fruit and veg, however that doesn’t need to matter.
Until 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 means of including leaves to the compost is to mow the leaves on the garden. Then throw the blended bag of garden clippings and chopped up leaves into the compost bin. It’s an ideal combine and can break down rapidly.
Right here’s a very easy information to creating your personal backyard compost.
You can even bag up leaves individually to make leaf mould. It is a splendidly nutritious mulch to your backyard borders, however I’ve discovered that leaves appear to decompose way more slowly after they’re all bagged up collectively.
If you’re going to bag up leaves, be sure they’re moist and tear air holes within the luggage. They are going to take at the least 1-2 years to interrupt down.
Can you permit leaves on lawns?
This query causes plenty of arguments. Having checked out a lot of them, I can summarise it.
In case you have numerous leaves, which lie in a thick layer in your garden, then it’ll take them months to interrupt down. In that point, your garden can be disadvantaged of daylight. This will trigger naked patches, particularly if in case you have numerous the thicker, extra leathery leaves.
Nonetheless, when you solely have a scattering of leaves over your garden, then they may break down naturally, including diet to the garden.
The best technique to take care of leaves on the garden is to run a mower over them. Use the next setting than you’d in summer time 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 rapidly than entire leaves will.
In america, the place most of the garden grasses aren’t native, this debate usually veers off into the ‘lawns are unhealthy’ argument.
It’s vital 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 dissipate comparatively few assets and are each sustainable and wildlife-friendly.
Yow will discover out extra about an easy-care sustainable garden right here.
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 ground all 12 months spherical. Forests and woods don’t scent unhealthy. And folks aren’t normally warned towards strolling in them due to ‘unhealthy moulds.’
However when you search whether or not leaves trigger unhealthy moulds (molds) on-line, you’ll discover a whole lot of warnings, nearly all from america, on the risks.
Actually moulds, funghi and fallen leaves are an element within the autumn. These can set off allergy symptoms, much like these from pollen in summer time. Just a few of those allergy symptoms and reactions will be extreme.
However I discover it odd that persons are way more involved about this in america than they’re within the UK.
Are our fallen leaves much less more likely to trigger allergy symptoms? Or do some international locations fear extra about leaves than others?
This will even be a quantity concern. When you’ve obtained one or two timber of various sorts in your backyard, you then gained’t have an enormous variety of leaves at anyone time. But when your property is surrounded by a whole lot of the identical deciduous timber all dropping 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 might even be price noting that nature doesn’t sweep leaves into an enormous pile, so maybe the steadiness of funghi and moulds could also be completely different if leaves are in piles somewhat than merely left.
And never all ‘moulds’ are unhealthy…
You’re actually 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 the majority sorts of funghi are excellent for gardens, serving to crops 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 just a few damaging funghi, akin to honey fungus and verticilium wilt. However sweeping up your leaves isn’t more likely to make plenty of distinction to them, somehow.
However, as with the whole lot, I believe it’s price taking a person method to this. Is there any scientific analysis performed 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 one more, and when you do get well being points in autumn, it’s vital to deal with them.
These funghi have been intentionally launched into the Wildlife Backyard at RHS Wisley.
Are fallen leaves toxic to canines (or different pets)?
As I mentioned in How you can 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 crops.
Plant poisoning is comparatively uncommon, however it’s critical to maintain an in depth eye on puppies, kittens and toddlers in a backyard as a basic security measure. You by no means know what they’re going to place of their mouths or what different hurt they may 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 just a few crops that are very poisonous, akin to oleander or ricinus. I personally don’t develop both for that cause. However you will note oleander throughout Europe, with numerous cats and canines sunning themselves in entrance of the bushes.
I’d recommend asking your native vet if there are crops in your space that appear to trigger issues with canines or cats consuming the leaves.
When you get a imprecise, basic reply, that most likely means the vet can’t keep in mind particular instances (so there most likely are few or none). In case your vet has handled poisonings attributable to pets consuming fallen leaves or particular crops, they’ll say so fairly clearly.
Can you permit 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 the moment 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 will be slippy if they’re coated in moist or frozen leaves. A good friend of mine says she has additionally slipped whereas strolling on her garden, so that’s one other issue to take note of.
Can leaves develop roots?
Leaves can’t regenerate or develop roots. You gained’t discover numerous tree seedlings popping up since you depart leaves in your borders or garden.
Every other issues?
There’s a great Instagrammer Alexis Nicole who says in her video: ‘depart the leaves. They gained’t break into your home and steal all of your wine.’
How refreshing to seek out one thing we are able to all agree on. I believe we are able to safely say that’s true for wherever you reside.
The ‘depart the leaves’ marketing campaign is all a part of gardening to assist wildlife. It additionally saves time, effort (and even a bit of cash) for the gardener, so this one is a ‘win/win!’
However, as with the whole lot, there’s no ‘one dimension matches all’ recommendation in gardening. When you’re reluctant that this may be just right for you, maybe strive leaving leaves on one border and see what occurs.
Let me know the way you discover it.
