Knowledge Base

We have years of experience in producing and sourcing some of the finest topsoils and with this experience comes knowledge, so we thought we would share this knowledge with you in the form of our knowledge base.  

Below are several articles we have put together to help you understand and make the most of your topsoil and garden.


A great combination: Turf and topsoil together produce the ultimate luxurious lawn

Harness the health-boosting properties that screened topsoil can bring to your lawn, and give your grass a helping hand. We stock some of the best blends of topsoil to improve drainage, increase soil fertility, manage pH and assist with the development of plants at all stages of growth. If your turf health is a concern, lawn topsoil from The Topsoil Shop can revitalise your lawn and create a more healthful, durable and hardy lawn. Topsoil is an amazing product that’s produced according to carefully-researched, tried and tested formulae for maximum effectiveness.

How can a screened topsoil bulk bag help restore the greenness of your lawn? By sprinkling a light layer of our screened topsoil onto areas of struggling growth you can increase fertility and help your lawn recover from, or prepare for, bad weather. With careful timing you can help build up resistance in your grass to poor weather conditions, as well as restoring underperforming patches when coming out of the colder months.


Helping recover your lawn: topsoil & soil improvers can be the difference between good and great lawns

Turf is an amazing substance- a deceptively complex system of microorganisms, developing and growing. Turf can come under stress under difficult weather conditions or when covered, for example by standing water, snow or fallen leaves. This can lead to many garden owners’ worst nightmare: a patchy, uneven and off-colour lawn. Unfortunately many don’t explore the potential of turf and topsoil to boost growth and help their lawns recover. If your lawn is suffering from poor drainage, fertility or growth, careful scarification followed by sprinkling a very fine, light layer of screened topsoil over your grass is a tried and tested way of improving water drainage and preventing lasting harm. Equally effective for helping new seeds take root in patchy areas of your lawn, the fertility and water management properties of topsoil can help improve both the thickness and overall health of your grass. What’s more, you only need a small amount to make a huge difference- making this a great job to add to your list when you’ve a topsoil bulk bag coming to develop your allotment or borders.

Check out our range of composts, turf & topsoil supplies, or contact our team, to learn more about the ways you can give your garden a boost with soil improvers.



Around this time of year, the sights and smells of summer gardens begin to pose a real temptation those whose gardens might only contain paving slabs. But for the enthusiastic amateurs seeking to transform their outdoors into a prospering flower garden, there are some realities to come to terms with: one of which is weeding.


What’s lurking beneath the surface of your garden?

Weeding might seem like a constant uphill struggle for gardeners, but it actually becomes easier over time. There will always be weeding to- especially annual weeds, the seeds for which can creep into your garden over the year, but on the whole weeding is a cumulative effort- as you continue to diminish the size and strength of perennial weeds, your weeding efforts will become easier. Perennial weeds spread through deep & often complex root systems that allow them to survive for years beneath the ground. You’ll need to commit to years of monitoring and digging before you finally eliminate them- it’s all about causing as much damage to the root network as possible, because as long as the fronds remain beneath the surface, the weed itself will return again and again.


Weeding or mulching?

The two means of fighting weeds- weeding (extraction) or mulching, are equally popular with gardeners seeking to reduce the prominence of weeds in their garden or allotment. In truth the two methods are not so separate- as effective mulching must be followed by some degree of weed extraction. Yet if your garden is suffering from a particularly heavy infestation of weeds, mulching can be a low-effort way to reduce them, limit their growth and spread and make for much easier removal. Simply cover the area between your plants, either with compost, grass clippings or leaves, to keep sunlight from reaching the weeds below. This will stifle weed growth and reduce water loss from the soil, and the organic matter should decompose into the soil. Ensure you leave the developed plants you wish to keep clearly exposed- the mulch will fertilise them, kill weeds and insulate them during colder months. Bear in mind that while this procedure increases fertility, h if that’s your main goal you could also consider top dressing or even plant food water additives. The other method of mulching involves a less sightly strategy- covering the weed-affected area with cardboard or black plastic sheeting to completely deprive the plants beneath of sunlight. In time they’ll shrivel and die, allowing for much easier removal. Unlike mulching with organic matter this approach cuts off the plants beneath completely from water as well as sunlight, which understandably causes a degree of trauma to the soil and won’t insulate as well- so ensure you time your choice of which form of mulching to use according to the weather.  

While regular gardens and lawns might benefit from weed killers and additional chemical additives, those growing fruit and veg might prefer a more organic approach that kills weeds and stifles any spread of plants into undesirable areas of border or allotment- this is something organic mulch does very well, and in addition it offers a wide range of drainage, fertility and insulation control qualities.

By comparison weeding is a simpler task- you can pluck the weeds out by hand (always satisfying when successfully ousting a particularly unsightly specimen) or using tools like a fork, hoe, trowel, scissors or even a specialist purpose-built weed remover to uproot them. In the cases of annual weeds, lightly hoeing the area removed the stems from the roots and allows the dead heads to be removed easily, raked away or simply left to rot into the soil. With perennial weeds a more rigorous approach, aimed at removing the roots entirely from the soil, is needed to prevent the plant from regrowing or spreading. Lots of specialist tools are available for this task, although a simple garden fork is often the most popular.

Weeding with a fork, hand fork or trowel should be undertaken every day, or as often as possible to keep weeds down and should be across your garden- as any area where weeds can flourish can lead to spread across the rest of your garden. If you compost, remember to separate annual weeds from perennials, as the latter can take over your garden or even compost heap, are hard to extract and should be disposed of.

We decided to test out B&Q’s foray into apps- the new Outdoor Assistant, which claims you can identify plants or weeds and get advice on gardening techniques.

B&Q recently conducted research that claimed while more Brits are gardening than ever, 10% are guilty of mistaking flowers for weeds, while 15% allowed weeds to grow thinking they were flowers. Helpfully they have introduced a new app for those unsure whether they’re weeding a border or demolishing grandma’s prize orchid.

Free to download and advertised as ‘Shazam for plants’ the app sets itself an ambitious task- using image-recognition software to identify any plant the user photographs. While other, similar apps are available, the promising mission statement and corporate brand made us decide to take this one for a test drive.

We found the app simple and functional, without unnecessary bells and whistles- which proved to be vital, as we ventured further into the garden it began to struggle with speed and connectivity. Several searches crashed or had to be abandoned after taking too long to load- leading to a series of searches being conducted on clippings inside with the benefit of WiFi.

Overall the accuracy was distinctly average, and while it didn’t seem the app promised to provide encyclopedic knowledge- in providing a selection of possible matches it came across as aware of its fallibility- correctly identifying 6 of the 12 plants certainly highlighted that work is still needed. Assuming that the majority of users are drawn in by the claimed ability to identify plants, we certainly hoped for more precise results.

Seeming to function better in well-lit conditions, it scored 4 for 6 in the first, border-based testing, correctly identifying primrose, tulip, daffodils and hyacinths- admittedly probably the easier end of the spectrum. Somewhat unfairly we decided to test it on strawberries’ distinctive leaves, which perhaps understandably was unsuccessful.

On the second, cloudier attempt (weeds, shrubs and pot plants) connectivity proved a huge problem, as did the gravel setting on which many of the weeds were situating- completely confounding it. The zoom required for a suitable picture produced blurry images that again failed to register and required several attempts- several had to be pulled up in order to be captured to the app’s satisfaction- though many of these still proved incorrect. It did however correctly ID an anemone and a particularly tricky Japonica- for a total of 2 for 6, slightly disappointingly. Eventually it crashed mid-way through a search- a fairly inauspicious ending to our experimenting. Admittedly there is an option to save a picture for searching later- though this seems like a fairly impractical measure for countering a poor internet connection in the garden.

Some observations:

-If you have gravel, don’t expect miracles. Gravel seemed to totally flummox the software, probably due to the variety of colours and textures interfering with the image recognition technology.

-If you have slow internet, you might be better off with a book. Despite an increase in urban gardening, many of those who garden aren’t fortunate enough to be situated in 4G hotspots- something that proved rather tedious during our time trialing Outdoor Assistant.  

-An option to retrieve previous searches would be ideal.

-Though ostensibly a plant-identifying app, there’s an awful lot of shopping options built in below the surface.

-British weather seems, as usual, to stop play. The app contains a marvellous gallery of high definition stock-style images, all showing crisp and lovely plants in full bloom in thoroughly Mediterranean weather. Perhaps predictably then, it seemed to struggle to find a match for some of our markedly less luscious offerings- particularly a fuzzy close up of shaded flowering broccoli as dianthus- which could lead to some interesting border choices from less experienced gardeners.

 Digital Gardening

Increasing numbers of Britons are gardening alongside using social media- with 24.3 million posts using the hashtag #garden in March alone. The RHS, meanwhile, has announced a £27 million investment in raising awareness of the positive effects of gardening- meaning that gardening could be about to take off as millions seek the therapeutic effects of ‘getting back to nature’, the RHS Claims. In the context of the decline of gardening and gardens, apps like Outdoor Assistant present an innovative, engaging and thoroughly 21st century solution to gardening illiteracy. Unfortunately there seem to be some problems that need ironing out- and while the idea certainly merits more development, there’s a lot of gardening books that can do the same job more reliably. 





We all seem to enjoy starting the year with a bit of a health kick. Of course, this doesn’t always last- but the same principle works for your garden, and if you stay the course a little extra attention in spring can help your lawn hit new highs all year through.

Once you dig the mower out of the shed, get yourself up and running with a light mow that leaves plenty of length on your lawn to promote hearty growth.

There’s more to setting your lawn up for the spring than a quick trim, though- consider scarification and aeration to improve drainage during those spring showers, and remove moss. But to give your lawn even more of a helping hand, make the most of the spring growing conditions with a top dressing with our specialist top dressing top soil. This will improve drainage, fertility and general lawn health throughout the year and help develop a thick, luscious lawn- and regular top dressing gives the soil structure itself a fertility boost that will benefit your lawn for the months ahead. Top dressing also helps level the lawn, creating a more even and fertile platform for even growth and that perfect smooth appearance.

Many gardeners how include top dressing in their springtime lawn care routine, due to the thorough boost it gives and how easily it can provide a thicker lawn in conjunction with overseeding- the best way to fill in any patches left by digging out weeds and moss that have sprung up during the winter period. has everything you need to make sure your garden gets off to a perfect start this spring- whether you’re keeping your lawn in pristine condition or growing veg in an allotment, we have something to help you get the most from your efforts.



The Plant Risk Register has been updated for 2017.


Responsible gardening means understanding invasive species and diseases- be sure to know the risks and regulations new for 2017. The Plant Risk Register was updated in January to cover the most recent concerns regarding plant and tree diseases.

In the latest updates to the register now includes some new risks, including

    Texas Phoenix Palm Decline – a phytoplasma disease killing palm trees in the USA

•    Acalolepta sejuncta – Asian longhorn beetle which attacks trees

•   Crisicoccus pini – Kuwana mealybug, a pest of pines recently introduced to Italy

•    Monilinia polystroma – Asiatic brown rot

•    Fusarium oxysporum f. sp. Cubense: a fungal infection effecting bananas.

While some of these may sound slightly exotic for the majority of UK gardeners, there are a number of extant risks that have been reassessed in the 2017 update. These include Candidatus Phytoplasma mali, cause of Apple Proliferation Disease in apple trees, now subject to increased monitoring and regulations following reports of increased spread inside Europe. Another serious disease is Candidatus Phytoplasma pyri, a cause of Pear decline that could potentially be a serious risk to the country’s perry orchards, and viewed as low risk but carrying the highest impact if allowed to spread to orchards. The Iris Yellow Spot Virus, a danger to onion crops, is considered a likely danger farmers and gardeners will have to deal with in 2017.

The spread of disease is something all gardeners need to be familiar with- as if allowed to spread to farms or to other vulnerable areas, they can have serious repercussions. By identifying and removing plants that carry infectious diseases, we can ensure our gardens don’t contribute to the spread of invasive or dangerous plant species, diseases or pests.

Gardeners everywhere rely on topsoil to support their gardens and allotments. But what’s actually in bought topsoil?


Nitrogen is a great plant fertiliser in low concentrations. All plants rely on nitrogen for healthy stems and leaves- so getting a steady, healthy supply is a perfect start for your plants. Plants require more nitrogen than any other nutrient, and for general health and growth you should consider nitrogen the main ingredient. However too much can cause serious harm to your plants- so make sure you water frequently and follow guidelines if adding any extra.  


Magnesium is vital for photosynthesis, and without it leaves will begin to wilt and die. Magnesium shortages often occur in tomato plants, where more erinaceous-friendly potassium feeds interfere with magnesium uptake.


Potassium is not just great for humans, it can help plants develop healthy fruits & leaves, by promoting water uptake, stimulating enzyme production, and boosting synthesis. Plants can’t thrive without a plentiful source of potassium, and will grow to be stunted, discoloured and less resilient than normal.


Unlike the other ingredients, phosphorus is beneficial for root formation, and though uncommon, in heavy rain it does happen. Without healthy roots, the plant will develop slowly, off-colour and vulnerable to bad weather.

If you’re considering using topsoil to boost your plants, these nutrients should be on the list of ingredients. The Topsoil Shop is the UK’s best bulk topsoil delivery service, combining affordable, great quality topsoil with an easy online ordering & local home delivery network to make it easier than ever to help your plants thrive. 


Know Your Topsoil

It can be hard to know which the best topsoil is for you- and if you don’t know your soil you may struggle to get your plants to thrive. The truth is, most people aren’t that interested in the science of soil- but it has a lot of very special qualities you can’t see. Most people are surprised to learn that fertile soil is a finite, non-renewable resource and won’t be around forever. And with 1.2-2 billion tonnes of food intensively farmed each year –around 50% more than is eaten- we may soon be hearing more about the decline of our fertile soil resources. Aside from news of impending doom & gloom, however, why should you take the time to learn about the miracle of natural topsoil?

Topsoil is vital to the growth of plants and, therefore, humans! But it normally only occurs naturally on the top few inches of the ground. It can go down to a few feet at most.

Most importantly, topsoil is teeming with life! This is what gives it its rich, deep, dark colour. Decaying matter and microorganisms also provide its odour and miraculous growing properties. When it occurs naturally, topsoil is home to more organic activity than the rest of the earth! In fact, the next time you’re in the garden, grab a handful- you’ll be holding more living organisms in your hand than there are people on the entire planet! Yet all topsoil is roughly half air and water (its water absorption properties are miraculous- one acre could hold almost ten MILLION litres of water) and 95% non-organic material. Despite being only 5% organic, topsoil is the product- and in many ways the basis for- all biological activity that’s ever taken place on earth. Centuries of plant and animal organisms dying & decomposing goes into producing every centimetre of topsoil. Yet industrial farming and other bad production practices are reducing available topsoil at an unsustainable rate. That’s why increasingly the agriscience has been taking steps to reduce the damage to topsoil, such as more and more advanced composts and soil improvers.

The great advantage of using bought topsoil is that you can tailor your choices to improving the soil fertility profile in your garden. Scientists have identified over ten thousand different types of local topsoil in Europe alone, and each type of soil can favour certain plants. Using bought topsoil, instead of relying on compost and local earth, can allow you to grow a wider variety of the species you choose.

The Topsoil Shop is a leading supplier of high quality bulk & bagged topsoil across the UK. We have depots across the country to ensure fast & hassle-free delivery of fertile, freshly dug topsoil. See our depot locations here.

Mulch Ado About Nothing (or Chicken Soup for the Soil)*


Restore vibrancy to your soil with some life-giving mulch! A healthy layer of mulch is probably the best favour you can do for your soil this Spring- and definitely the cheapest. Readily available from our shop or easy to prepare at home (provided you know your garden and its soil type there’s no excuse not to get the most out your garden in 2016 with some mulch!

February is the perfect time to consider your garden’s needs for the coming year, and though it may not feel like it, now is the time to think of the summer that’s just around the corner, and prepare our allotments and gardens for the warmer, drying months that will pose challenges of their own. All this because, for our plants at least, the rain of the last couple of months may soon be missed.   Unfortunately our climate limits how many projects we can undertake for another month or so, but if you want to take a positive step now toward a better garden this year, consider preparing and laying out some late-winter mulch to seal up your soil through the dry summer. Now, spring mulching is sometimes a contentious issue. There are those who feel mulch is best used to insulate your soil against the winter cold, and should be laid out in the autumn to warm the soil. Mulch decomposes, which leaks nutrients into your soil and can even generate a tiny amount of heat- which is just what your trees and perennials are after through the winter. However it’s been suggested that mulching in spring can act to seal entire beds, too, this time against moisture loss. A long dry summer (now replete with increasingly common hosepipe bans) can ruin your soil and turn your beautiful beds into dehydrated deserts! A healthy couple of inches of mulch now can trap in that moisture (one thing we have plenty of) and stops a hot summer from crisping your plants.  Not only this, but of course mulching will the preserve the fertility of your topsoil, and even tops it up, just as it does in winter. So if your soil is prone to letting your plants down for nutrients, or if you remember last summers’ dusty dryness, top up a 5cm layer of mulch over your entire bed and feel sure that some of the winter rain we’ve enjoyed so much of recently, won’t up and disappear as soon as we hit the hot months.

A new year is upon us. Perhaps it is one of your aims for this upcoming year, or indeed your new year’s resolution, to get out in the garden or greenhouse and start growing your own plants, fruits and vegetables. There is no time like the present. Although some people are sceptical of the ability to grow quality produce in the UK over winter, there is plenty opportunity to grow successfully in January.

If you have a backlog of winter tasks that remained incomplete, January is the ideal time to finish such jobs before the worst of the cold weather arrives in February. It is not typically the time of year to be growing outside but there are plenty of vegetables that can be grown in January with a view to sowing in autumn. This includes Aubergines; cabbages; carrots; cauliflowers; leeks and onions to name but a few.

If you have a frost free greenhouse you can grow lots. Plants and vegetables that are more typically cultivated in warmer months can flourish in a greenhouse environment. Sweet peas are a seasonal favourite to grow at this time of year and they can be started in gentle heat now as one of the first things that you attempt to grow in 2016.

You can also consider growing Pansies in a greenhouse with the view to moving them outside when summer arrives to create a glorious, colourful display in the sunshine. Similarly, Lobelia can be grown and moved across to hanging baskets and containers at a later date to give a bright and summery show.

All you need for successful growing is a good quality soil full of nutrients. You can do without chemical fertilizers and sprays. If you get a high quality soil they will not be necessary. The cash saved by buying excellent sterilized topsoil can instead be spent on plants and pots.

Multipurpose compost should be sufficient for your growing needs but if you really want top results for growing vegetables then opt for specially formulated vegetable compost. A good soil mix for growing in greenhouses is a half and half mixture of rich garden loam and compost.



Using quality topsoil in your garden, such as the organic topsoil available from Topsoil Shop, is a vital component of plant growth. There are many reasons for this, with the most prevalent being that it contains the highest concentration of micro-organisms and organic matter, making it the area of soil where the vast majority of biological activity happens. As a result, this is where a plant will have most of its roots bedded in order to ensure that it gains as many vital nutrients as possible. However, there is a considerable environmental issue known as topsoil erosion which is severely threatening the amount of good quality topsoil in the world.

Topsoil erosion is the process of the topsoil layer degrading due to it being washed or blown away, and can also caused by a number of conventional farming practices, given that yearly ploughing and replanting of soil is actively encouraged. There is a serious concern amongst experts that given the current rate of deterioration, the amount of quality topsoil left in the world will only last around 60 years. This is because an inch of topsoil can take anywhere between 500-1000 years to form naturally. Chemical farming processes are known to remove large amounts of carbon from the soil, making it less nutrient-rich and damaging its structural integrity, which also results in less water being absorbed by the soil. This could lead to a situation wherein more food is required due to an increasing global population, and yet we may not be able to produce enough due to reduced levels of soil productivity.

There are numerous different solutions which have been proposed, including moving to more widespread organic farming techniques, and by adopting no-till farming (where there is a reduced the amount of soil disturbance).
