Fertilisers play an important part in helping your plants grow. The faster the plant grows, the more it will benefit for usage of fertilisers. It is not always necessary to use fertilisers if you have good soil, but using them anyway can produce more flower blooms or a higher crop of edible produce.
Fertilisers are basically concentrated sources of plant nutrients. It is important to make sure you are choosing the right nutrients for what your plants need. If you plant is showing signs of nutrient deficiency, such as yellow leaves or discolouration in varying patterns, you will need to choose your fertilisers more carefully.

Need to know which fertiliser to use?
- All purpose plant food is quick and easy way to help boost plants, especially when in flower or fruit. These feeds are rich in nutrients to help encourage plant and root growth. These will work for most plants, fruit and vegetables.
- Ericaceous plants such as Rhododendrons, Azaleas & Camellias need a particular type of soil and fertiliser. Only use products that help with keeping a low lime environment (pH 5 - 5.5) such as the below.
- Orchids need a very particular environments to thrive, it only makes sense they would need particular feeds and fertilisers. Orchids should not be fed with general purpose plant foods for many reasons. Most importantly the nitrogen supply in the mass market product will usually contain significant levels of ammonia and urea. Urea in particular can become toxic very quickly in orchid growing media and is best avoided for that reason. Have a look in our News and Ideas Hub, we discuss how to care for an orchid.
- Potatoes need a loose acidic soil (pH 4.8 - 6.5) to really thrive. They also need a good amount of Potassium and Nitrogen, meaning you have to make sure you choose soil and fertiliser that supports these needs.
- Roses are a plant which take a lot of nutrients from the ground around it, and while they can survive without fertilisers, they will struggle. To make sure you rose is growing strong shoots and has an abundance of flowers, you will need to give it feeds high in Nitrogen, Phosphorus and Potassium.
- Seaweed has always been used to help improve soil quality as it contains several plant nutrients, including Nitrogen, Potassium, Phosphate and Magnesium. Seaweed is a useful choice for those who wish to be a more organic gardener as it is not a synthetic fertiliser or made from animal products, and usually supplied from renewable, sustainable sources. Calcified seaweed is also a good alternative to Garden Lime.
- Tomatoes are like many annuals, they require a lot of nutrients to grow well. Before you start, you need to find out the pH of your soil, as this will affect the plant from the beginning. Using a tomato compost will make sure your plant growth starts strong. From there, a feed is required usually every 6-8 weeks, depending on soil quality. Make sure you read the label to check recommendations.
