10 Best Fertilisers UK 2022 | Westland, Miracle-Gro and More

First up, we have this organic, all-purpose manure that is specially formulated to ensure that your garden plants flourish. How does it do this? Well, that's down to the competently blended rich nutrients found inside. On another note, you'll also be getting 80 litres for the price, which is quite a steal. 

There is one downside, though – the NPK is not stated. While this isn't uncommon, when buying such a large amount, you'll want to make sure it's got the goods. Still, if you're looking for quantity at a competitive price, it might be worth the punt. 

This liquid plant feed from Grow Mate has some serious benefits. For example, the company say that induces up to 400% more flowering and fruiting! Not only that, but it will also increase soil fertility, therefore, establishing a healthy living microcosm in the root region. 

Also, due to the formula being completely organic, it's safe for curious pets and use around children. However, owing to the fact it's all-natural, it has quite a strong smell that can stick around for up to 12 hours. Something to be aware of if you're using it for indoor houseplants! 

The big selling point of this product is that not only does it fertilise your lawn, but it also contains a weedkiller, meaning you don't have to worry about any buttercups, dandelions or daisies getting in the way of your perfect lawn. It's not as multi-purpose as some, but it will perform its job very well. 

This fertiliser from Growth Technology is specially formulated to increase the health, growth and flowering of your indoor plants. It's a precise, premium quality option that has all the nutrients needed for optimal plant happiness. As with most liquids, it just needs mixing with water – around 5 ml should do the trick. 

Although suitable for all houseplants, it does work especially well with particular types, many of which most of us have at home, such as ferns, palms, poinsettias, cacti and succulents. The only downside is that you'll need to be patient. While the nutrients may be fast-acting, the additional growth can take time to yield. 

Miracle-Gro is one of the nation's most trusted brands when it comes to gardening products, and they always offer good value. Our first recommendation is this all-purpose soluble plant food that's suitable for both outdoor and indoor plants. This fast-acting food needs to be replenished once every two weeks. 

The company states that its formula will grow your plants twice as big as those who've had no food, which is a pretty decent return for such a cheap product! Be careful, though, as it means it will also grow your weeds twice as big, so you'll want to make sure that the garden is meticulously pruned first. 

While we're unable to confirm or deny whether this is, in fact, the original plant food, what we can tell you is that it's known for working like a treat and leaving plants greener and more vibrant. We can see why it would, too – just check out the relatively high NPK ratings. 

Even with the generous dose of the three essential nutrients, however, it's a total bargain, and easy to stock up with online. If you're looking to give all the potted greenery in your life a helping hand without breaking the bank, then Baby Bio will be more than capable of providing that service. 

If you're looking to really bulk up the growth of your flowers, fruit or veg, then Richard Jackson's Premium Plant Food is the one for you. This has a whopping percentage of additional nutrients and is essentially the equivalent of giving (healthy!) steroids to your plants. 

With that in mind, it's not surprising that this award-winning formula has sold over a million packets and is a go-to for tens of thousands of gardeners. It's a little expensive, which is why it doesn't quite make our top three, but if you've got the money, you won't be disappointed. 

If you want to stick to your organic principles, then of all the choices in our ranking, we would opt for this from Westland. This not only prolongs flowering and fruiting but will also help produce a greater yield, which could make your garden pop just that little bit more. 

The formula is available in many different package sizes from 1.5 kg all the way up to 10 kg, which is handy as it means you don't have to commit to it straight away and can test it first. Our top recommendation if you have pets or just want to keep it natural. 

This is another of Miracle-Gro's top products, which still promises twice the growth but is even simpler to use. Plus, it's supposed to show visibly better plants in just seven days, which is extremely quick!

Moreover, the formula – as stated – is all-purpose, so you'll only need to buy one bottle and it'll work with all of your potted or bedded plants, flowers and vegetables. A final appealing factor is that although this is a chemical formula, it's not dangerous to children or pets. 

Taking our number one spot is another of Westland's products, but this time it's their Growmore. The main reason it got the headline billing is because of the consistency of the NPK, meaning that it will be compatible with a range of different plants. Not only that, but it will build your soil fertility too. 

To feed your greenery, the instructions state you should use around 35 g every 4 to 6 weeks and sprinkle around the areas you wish to grow before watering. It's also not too expensive, achieving an excellent quality to price ratio. Great for all around the garden!
