Mulch ado

There are two types of jobs in the garden: those that require a great deal of careful thought in either the planning or the execution, and those that require little or no brain power at all. Mulching is the latter kind, which one might categorise as ‘drudgery’ or ‘simple pleasure’ depending on your mood, the state of your back muscles, and the prevailing weather. Personally I place mulching in the simple pleasure category: a perfect job for the end of the year when one’s brain is saying ‘no more’; a somewhat mindless task that feels virtuous, requires no decision making, and has a pleasing aesthetic result. You can listen to music or an instructive podcast while mulching, or ruminate on higher thoughts.

For those who have never indulged in the pleasant occupation of mulching a garden and are wondering what on earth I am talking about, mulching is the application of organic matter to the surface of the soil in order to protect the soil from erosion, raise the temperature of the soil, and aid water retention. It replaces the organic matter lost through digging, and is taken down by earthworms to act as a food source for the soil microbiome, ultimately providing nutrients to the roots of your plants. Adding organic matter to the soil will help to break up a heavy clay soil, and equally help to bind a sandy, dry soil. It also buries weed seeds, and certain mulches can make life harder for slugs.

In the wild, nutrients are returned to the soil through a combination of leaf-fall, dying plant material, animal excrement, and animal carcasses (both large animals and tiny insects). However, in our gardens we tend to harvest or tidy up and remove fallen leaves, plant material and animal waste. The ecosystem of the average garden is greatly limited and impoverished in the name of tidiness, and therefore we are obliged to add back to the soil what we take away.


There are various good organic mulches that can be used: farmyard or horse manure is ideal, but it must be well rotted. Others include green waste from the council, finely shredded bark, garden compost, leaf mould, shredded seaweed, composted bracken or sheep’s wool, and commercial products such as Strulch. It pains me to say that plastic sheeting and weed control membranes such as Mypex also come under the category of mulch, though the onomatopoeia is a damp squib when applied to these rustling, unnatural and most unsquelchy of items. Though sheeting can protect large areas from soil erosion, they clearly do not supply nutrients to the soil, and are frankly far less satisfying to apply or gaze at and what is gardening for if not for satisfaction and gazing?


I am lucky in being able to source small quantities of horse manure from Emily, my grandmother’s horse. It’s always well rotted, but contains a lot of nettle seeds, and I can’t bring back enough for the whole garden. So as an early Christmas gift to myself, I ordered eight sacks of organic enriched manure from Garden Solutions, a local company that sells a variety of mulches and soil enrichers (their website is here). It duly appeared in my front garden as though delivered by Santa Claus, and the following Saturday I leaped eagerly from bed and got to work. First using a hand cultivator to gently break up the soil surface and dislodge any weeds, I then applied double handfuls of the lovely mulch and spread it over the surface of the soil in between the plants, about two inches thick. There is no simpler pleasure than the handling of dark, rich organic matter in one’s bare hands, especially if the sun is shining and it’s almost Christmas.

It is said that a clay soil should be mulched in spring, and a sandy soil should be mulched in autumn, but in fact a mulch can be applied to any soil at any time of year. The reason I apply mine in December is a combination of factors. The bulbs are all in, but have not come up yet and so do not get in the way. Rather, they come up through the mulch about a month later. Take my word for it that trying to apply a mulch around bulbs that have already sprouted is a challenge, especially where those dratted flopping allium leaves are concerned. In December there is not a lot else to do in the garden anyway, the bare soil exposed by plant die-back looks bare and vulnerable to heavy rains, and a clean, dark mulch is the perfect foil for the virginal white flowers of my beloved snowdrops and Helleborus niger.

The soil in our front garden is dry and poor due to the proximity of the street trees and also due to the privet hedge, which is the main reason that I redesigned the front garden with its path around the edges. This is how the garden looked before I mulched it:



And below is the garden after mulching and a tidy-up. As you can see, the soil is now much darker, which will help with heat retention. And if you can just about see the hellebores below the Sorbus cashmiriana you might get an idea of how nice they look against the darkness of the mulch.


Now that the brick maze is finished,  I am looking forward to writing a post all about the design and execution. In fact, this would have been the post you’d be reading now, except I’m writing this from Derbyshire and all my ‘before’ photos are on a hard drive 300 miles away in Edinburgh, so it will have to wait. Meanwhile, I am off outside to feed Emily her breakfast, with a mind to many more satisfying manure-spreading operations in Decembers for years to come.

  1. Garden Solutions is my supplier of choice as well – love that they come and drop off the bags whether you’re there or not. Your brick maze is beautiful! Where are you getting the bricks from? I’m hoping to start edging some of my beds with bricks and maybe even put down a path or two, but collecting bricks from skips is slow going

    1. Yes, GS are fabulous. Such helpful people to deal with – huge range of products, prompt responses to emails, and a very effective delivery service. I feel lucky to be so local to them. My bricks are bog-standard B&Q pavers, 40p a pop. I would have loved reclaimed ones, but they tend to be expensive, and I needed something a bit more uniform. There’s a reclamation yard out near Broxburn which sells bricks. I’ve not been there myself but could be worth a try. Not the cheapest, though. You’re welcome to the nine and a half bricks that I’ve got left if that’s any use!

    1. Thank you – very glad to have inspired some mulching action in far-flung corners of the globe! It’s hard to get it in among the plants if they’re in growth. Most things die right back here in winter, a moment I enjoy almost as much as the exuberant flourishing in summer.

  2. I like your design and look forward to reading all about it. I agree that mulching can be a very satisfying simple task especially if it is a warm winter’s day with lovely sunshine.

      1. We’ve also had lovely days to be outside but a lot of nights already with frost which is unusual here. We are predicted to have minus 6 on Friday night!

  3. I prune, he chips, I mulch. Here I want to shield the earth from too much sun, and encourage the sand to be kinder to my plants.
    Brick maze is lovely. And that soft turquoise pot!

  4. Looking forward to reading more about how the brick maze came about Joanna and to find out what you will plant within it. Well rotted horse manure is excellent when you can get hold of it and even better if you know the producer first hand! Here I have bags of leaf mould ready to mulch my snowdrop border although the bulbs are already through and in some cases flowering.

    1. Ah, leaf mould is quite the most precious stuff! For logistical reasons (storage problems) I can’t really collect it in large enough quantities here, so I envy your ability to mulch an entire border with it. A snowdrop border is a wonderful thing – I expect you’re looking forward to enjoying them as they come out over the next months. One day I get round to planting some early snowdrops so that I can have some to enjoy before my bog standard G.nivalis come out in February.

  5. Mulching takes on a slightly different aspect here, I think, because we mulch in an effort to keep the soil temperature down in the summer and to try to keep it damp as best we can. It’s a bit difficult just now as we are experiencing a heat wave…no temps below 36 C for the foreseeable future and definitely no rain. Your maze looks very effective, and the plants within it very snug.

    1. Goodness – I wouldn’t know how to cope with temperatures like that. Mulching must be an absolute necessity in conditions like those. But isn’t it amazing how the same single solution (mulching) can ameliorate quite opposite problems (dry soil, wet soil, clay, sand etc).

  6. Oh I was thrilled to see this, Joanna – the outcome of all your planning! It looks so effective and especially so for a front garden like yours. I look forward to reading more about it and seeing it in its full glory in the growing season. I too had been getting some manure from a friend, but realised that nettles were appearing in the garden so bought a bulk bag this year

    1. Thank you Cathy – I am glad you think it looks all right! I need to work on the planting design a bit more. Obviously it is a bit bare in winter, and looks good in spring, but summer and autumn weren’t quite up to scratch so I’m looking forward to improving it this year.

  7. Oh how I wish I had an Emily. I envy you your Emily mulch maker. What a sweet face she has too.
    I will look forward to reading about the maze making. It looks so neat and tidy with a fresh coat of mulch.
