5 Best Spring Lawn Feed of 2025

Suitable for established lawns, this Sportsmaster Spring and Summer Lawn Feed helps create a carpet of greener, denser grass. It can be used any time from the start of spring to the end of summer, breaking down quickly for great uptake of nutrients.

With a NPK ratio of 9-7-7, it’s a reasonably balanced formula, with a slightly higher nitrogen content in order to encourage growth during the growing season.

Coming in a 25 kg bag, the manufacturers (Sportsmaster) recommend spreading this fertiliser at a density of 40 g/m². It can be spread either by hand, or using a rotary/drop spreader, as long as you can ensure an even application. When used at the recommended rate, one 25 kg bag should cover an area of approximately 600 m² – more than suitable for most large lawns.

Given that only a couple of applications are required per year, one bag will last most gardeners for at least a couple of years.

There is some maintenance required after using this lawn feed as the granules need to be well watered in; however, it is relatively forgiving and doesn’t often leave scorch marks. If applied during a time when rain is expected, you won’t have to do as much manual watering either.

In some cases, improvement on the lawn can be seen within a week, and generally speaking, there is a noticeable difference in the appearance of the lawn after a couple of weeks. It’s a great way to help grass recover from the wear and tear that is more common over the spring/summer months when we’re all outside more.

There is also a 100 g sample pack of ‘Gardeners Dream Hardwearing Lawn Seed’ included. It’s only enough to cover a couple of square metres, but there’s certainly no harm in having a little freebie thrown in.

Overall, this is one of the best lawn feeds for spring because of how quickly it gets to work and how easy it is to apply. For lawns that tend to get a little tired-looking in the warmer months, it’s a great option to consider.

Moowy Spring Boost Lawn Feed is a fast-acting fertiliser that can create a tall, thick carpet of grass in approximately four weeks – and that’s if you’re starting from zero.

In cases where a lawn is already established, benefits of using this lawn feed are often visible in 1 – 2 weeks.

It’s available in several different bag sizes, with the smallest 1.25 kg option being suitable for small/medium gardens, or repairing specific areas. It’s also a good purchase if you’re worried about wasting money, or fertiliser, and want to avoid buying a bigger bag than necessary.

Like most springtime lawn feeds, it has a higher percentage of nitrogen than other nutrients, contains 12 % nitrogen, 5% phosphorous, 5% potassium and 2% magnesium oxide. The magnesium oxide isn’t present in all fertilisers and is aimed towards improving photosynthesis (and grass green-ness).

Also, although this product is geared towards springtime use, Moowy state that it can actually be applied any time from February – November, meaning it’s a great option if you only want to buy one fertiliser to use (almost) all year round.

The granules are easy to distribute, and can be used with spreaders to make the process easier. After application, this lawn feed is relatively high maintenance – requiring a lot of water to ensure that the nutrients are absorbed into the ground as intended.

Whether you’re starting the lawn from scratch, or are looking to give existing grass a boost, this is one of the best lawn feeds for spring that will show quality results in a small amount of time.

Available at a reasonable price for such a sizeable bag, this 25 kg Nutrigrow Granular Fertiliser is a good value choice for medium/large gardens.

With an NPK ratio of 9-7-7, it contains the expected nutrients for a springtime lawn feed – slightly higher quantities of nitrogen compared to phosphorous and potassium. It works reliably, achieving good results in approximately 4 – 6 weeks.

The lawn feed helps makes lawns noticeably greener, and provides a good boost once the warm weather starts coming around once more. If you find that your lawn is often looking worse for wear after winter, this is one of the best lawn feeds for spring – giving grass a well-deserved pick-me-up.

It can also be applied from as early as March, up to September, so there are a lot of opportunities for treating the lawn, even as summer starts moving towards autumn. The lawn feed stays in the soil for approximately six weeks after application.

With relatively large granules, measuring between 2 – 3 mm, the Nutrigrow Granular Fertiliser is easy to spread, but it can take a lot of watering to persuade it to dissolve. This may involve watering the lawn several times a day, or using sprinklers to encourage the nutrients to sink into the soil.

This is one of the best lawn feeds for spring if you want plenty of fertiliser at a reasonable price. Although it might not show the fastest results of all the products featured on this page, when grass does grow it is thick and deeply green.

With an impressive NPK ratio, this Proctors Spring and Summer Grass Feed is designed to give grass a real kick once spring rolls round.

Whereas the majority of fertilisers featured on this list have an NPK ratio of 9-7-7, this Proctors Grass Feed contains a higher proportion of nitrogen, with a ratio of 11-5-5. It significantly increases the rate at which grass grows, and can be used to boost recently-planted grass seed as well as well-established lawns.

Along with nitrogen, phosphorous and potassium, this grass feed also contains iron (to help fight moss) and magnesium oxide.

The 20 kg bag contains ‘mini-grain’ granules and will cover an area of approximately 571 m². Due to their size, spreading these granules can be slightly more difficult than working with larger fertiliser; there may be more trial and error involved with finding the correct distribution.

Nevertheless, the results are impressive and grass grows in thick and appears a deeper shade of green. Improvements in the health of grass are often visible within one week, and customers often report seeing a marked improvement in the appearance of the lawn within four weeks.

It’s best applied just before a period of rain, as the lawn feed needs plenty of watering in.

If you’re keen for something that will get grass growing after winter, this is one of the best lawn feeds for spring on the market. With such a high ratio of nitrogen, it’s suitable for giving grass a sizeable boost once the growing season starts.

If you think your lawn is going to need several applications of fertiliser to get it back to full health after winter, the Bridgewater Garden Supplies Spring Lawn Feed is a good option to consider.

Unlike some fertilisers that remain in the soil for six weeks or more, this fast-acting lawn feed can be applied 2 – 3 times during early spring/summer, with applications as little as four weeks apart. This can help give the lawn a prolonged nutrient lift.

It has an NPK ratio of 9-7-7, much like the majority of the fertilisers featured on this page. It has a marginally higher content of nitrogen compared to phosphorous and nitrogen. However, unlike the other lawn feeds, it also contains 13% sulphur.

Sulphur is quickly becoming viewed as a one of the principal nutrients for aiding plant health, so it could be an invaluable addition depending on the existing composition of your soil.

This mini-granule fertiliser can be used on newly-established lawns, or older lawns that are looking a little tired. Applied from March to June, it can help aid new growth, or refresh existing grass.

On new lawns, Bridgewater Garden Supplies recommend applying this fertiliser at a rate of 70 g/m², and 30 g/m² on existing lawns.

It’s one of the best lawn feeds for spring if you’re looking for a product that contains sulphur, and it’s useful for tired lawns due to the number of applications that can be done over a relatively short period of time.
