A lush, green lawn is the pride of many homeowners. But keeping your grass healthy all year round takes more than just watering and mowing. Fertilising your lawn at the right time with the right products is key to its growth and resilience. I’ve put together a simple annual calendar to help you plan your lawn fertiliser treatments throughout the year. This way, you can enjoy a vibrant lawn in Bognor Regis and Chichester no matter the season.

Why Follow a Lawn Fertiliser Calendar?

A lawn is a living thing that changes with the seasons. It needs different nutrients at different times to grow strong roots, fight weeds, and stay green. If you fertilise too early or too late, you might waste time and money, or worse, harm your grass.

By following a fertiliser calendar, you give your lawn what it needs when it needs it. This helps prevent common problems like patchy grass, weeds, and disease. Plus, it makes your lawn more drought-resistant during dry spells.

Planning Your Lawn Fertiliser Treatments by Season

Early Spring (March to April)

Spring is when your lawn wakes up from winter. It needs a boost of nutrients to start growing again. Use a fertiliser high in nitrogen to encourage fresh, green shoots.

At this stage, We recommend Amvista L1 Turf Boost Fertiliser. It’s designed to feed your lawn quickly and promote healthy growth after winter. You can find more details about it here.

If you have any moss visible from the winter months then you should then consider using a fertiliser with added iron Sulphate (Fe), which will kill off the moss but will also feed your grass the nutrients it needs to start growing again.

We recommend a product like Maxicrop No 2 Moss Killer and Lawn Conditioner. You can find more details about it here.

Apply the fertiliser once the soil temperature reaches about 7°C. This usually means waiting until mid to late March in our region. Avoid fertilising too early when the ground is still frozen or waterlogged.

Early Summer (May to June)

By late spring, your lawn is growing fast. It needs a balanced fertiliser with nitrogen, phosphorus, and potassium to support strong roots and thick grass.

A good choice here is Amvista G3 Spring & Summer Fertiliser. It helps your lawn build resilience against summer heat and wear. You can check it out here.

Apply this fertiliser once or twice during this period, depending on your lawn’s condition. If your grass looks healthy and thick, one application is enough. If it’s patchy or thin, a second application can help.

Summer (July to August)

Summer can be tough on lawns with heat and less rain. Avoid heavy fertilising during the hottest months as it can stress the grass. Instead, use a slow-release fertiliser that feeds the lawn gently over time.

Amvista L5 Slow Release Liquid Fertiliser is perfect for this. It provides nutrients gradually, helping your lawn stay green without pushing too much growth. More info is available here.

Water your lawn deeply but less often to encourage deep roots. Avoid fertilising during drought conditions to prevent burning the grass.

Autumn (September to November)

Autumn is a crucial time to prepare your lawn for winter. Use a fertiliser rich in potassium to strengthen roots and improve disease resistance.

Applying a product like A1 Lawn Ultimate Autumn Winter Lawn Fertiliser helps your lawn store energy for the cold months. It also helps repair any damage from summer wear. You can learn more about it here.

Apply this fertiliser in early autumn, around September, and again in late October if needed. This will help your lawn recover and get ready for winter dormancy.

Winter (December to February)

During winter, your lawn goes dormant and needs very little fertiliser. Avoid feeding it unless you have a mild winter and your lawn shows signs of growth.

If you do fertilise, use a light application of a winter feed with low nitrogen. This helps maintain root health without encouraging top growth.

Comparing Fertiliser Products for Your Lawn

Choosing the right fertiliser can be confusing. Here’s a quick comparison of the three products I mentioned:

|-----------------------------|--------------------------|-----------------------|----------------------------------|

| Progreens - Amvista G3 Spring & Summer Fertiliser | Late Spring to Early Summer (May-Jun) | Balanced NPK (Nitrogen, Phosphorus, Potassium) | Supports strong roots and thick grass |

Using these products at the right time helps your lawn stay healthy all year. You don’t need to use all of them, but picking the right fertiliser for each season makes a big difference.

Tips for Applying Lawn Fertiliser

Always read the instructions on the fertiliser package. Different products have different application rates.
Use a spreader for even coverage. Uneven fertilising can cause patchy growth.
Water your lawn after fertilising to help nutrients soak into the soil.
Avoid fertilising before heavy rain to prevent runoff.
Mow your lawn a day or two before fertilising for better nutrient absorption.
