Best Plant Food in the UK

Richard Jackson Flower Power Premium Plant Food will allow you to sustain the largest gardens. The 1.5-kilogramme tub will give you 1350 litres (~300 watering cans) of feed.

Setting volume aside, this product works on all plants, indoors and outdoors, including green (foliage) plants. You will not have to purchase separate feeds to nourish roses, azaleas, orchids, tomatoes, the product feeds all flowers, fruits, and vegetables.

Its multi-nutrient formula is packing extra-high potash levels, improving the crops' flavour and making the plants more resilient against pests, temperature fluctuations, and the elements. Even through the harshest winters, this solution makes sure the plants survive.

Now, probably because the blend contains countless premium nutrients, seaweed extracts, bio-stimulants, and a wetting agent, the solution takes more time to absorb than most plant feeds. Also, that might be the case because the product is using granules. Besides that, not unlike most products like that, these granules should be used between March and September.

To give you the gist, Richard Jackson Flower Power Premium Plant Food will let you grow more fruits, vegetables, and flowers than you could before.

Miracle-Gro All-Purpose Concentrated Liquid Plant Food does not perform miracles. Instead, the product works thanks to its thorough, well-balanced formula.

Using Humifirst® fertiliser that's packing more organic matter than most fertilisers, the solution produces excellent results. The improved formula will be stimulating growth and yield, accelerating root formation, and increasing the plants' resistance against environmental stresses.

To add more, the formula's slow-release approach feeds the plants evenly, so you will not have to re-feed them every few days. Generally speaking, the product's effect lasts two weeks but you'll start seeing visible results after one.

You can use this product from March to September, feeding any plant, from flowers to fruits and vegetables, indoors and outdoors. Even the bottle here is pretty great, made from recyclable materials except that the cap can make pouring somewhat challenging but, with time, you'll start getting used to it.

All things considered, Miracle-Gro All-Purpose Concentrated Liquid Plant Food is basically the superfood that most plants these days need to not only survive but actually thrive. The natural ingredients inside this solution will allow plants to grow twice as big as they were before.

Miracle-Gro Indoor Concentrated Plant Food does not fancy the outside world. No, this product will be feeding house plants. From cactuses (cacti?) to citrus and bonsai plants, this liquid solution can feed them all. Blending 9 different nutrients and an NPK 7-3-5 fertiliser, its high-nitrogen formula will make the leaves glowing green. Even when the plants are not as exposed to sunlight as they would like to be, the formula will make sure they're able to grow big and strong.

Plus, this is easily the most practical product within this list. All you have to do is remove the security clip and turn the pump open. Using the dispenser, you'll have no issues applying the precise amount required. The 0.236-litre bottle will give you around 100 litres of feed. You can use the product all year round, from January to December.

From where we're standing, the product's downsides are only limited to the specific, somewhat chemical smell that the product leaves behind. But, considering that the smell evaporates and goes away pretty soon, we can recommend Miracle-Gro Indoor Concentrated Plant Food to anyone who wants to make sure the plants inside grow strong and beautiful, creating this wonderful green oasis inside your home.

Doff Ericaceous Plant Feed has been formulated to feed ericaceous plants. Sure, the name makes that obvious enough. Still, factoring in that the solution can feed anything from rhododendrons and camellias to azaleas, magnolias, and most lime-hating plants, you need to outline its application anyway.

Aside from them, the product can stimulate lime, chalk, and alkaline soils, improving growth and maintaining large and healthy blooms. Contributing an NPK 6-3-7 fertiliser and multiple micronutrients, the solution allows the plants to absorb more moisture and minerals from the soil, making them more resistant against droughts and allowing these plants to thrive even under scorching heat.

The 1-litre bottle will make around 65 watering cans, even though you'll unlikely be able to reach the advertised 300 litres of feed. On the bright side, the cap seals the bottle shut, eliminating leakage during transportation. Lastly, the product can be used starting in March and ending around September.

As long as you're looking to grow ericaceous plants, this plant feed will fit that bill. The dosage is easy to figure out, so even the least experienced gardeners will be able to grow the healthiest plants.

Phostrogen All-Purpose Plant Food follows the standard playbook deployed across most plant feed. To kick things off, the product will produce the best results when applied anywhere between March and September. Using this 0.4-litre box, you'll be able to make ~180 litres worth of feed. The granules that the product is using will last more than liquid solutions, so you can store this product without worrying about the expiration rate. Yet, these granules are easily dissolved.

Before anything else, the product will be promoting healthy green foliage, abundant flowers, fruits, and vegetables, producing long-lasting blooms and lush greenery. The micronutrients inside these granules will also make the plants more drought-resistant and help them develop the strongest, healthiest root system. While the granules are not as fast-growing as the more expensive seeds from big brands, slow and steady usually wins the race.

You can use this product to feed plants indoors and outdoors, using the included scoop to measure the right amount. Even though the box looks bland, what we have here is an effective and well-balanced fertilizer for plants and flowers with trace elements that will bring fantastic results and make the plants grow happy and healthy.
