Early spring is an important time for lawn care, and for learning how to wake up a lawn. But over-fertilizing a lawn in spring can do more harm than good, often just as the grass is coming back into active growth. Applying too much feed – particularly high-nitrogen fertilizers – can result in soft, weak grass that looks green initially but is more prone to stress, wear, and drought later in the season.

It can also lead to fertilizer burn, where excess salts draw moisture out of the grass roots, leaving yellow, brown, or scorched patches. In spring, when soils are often still wet, any surplus nutrients are more likely to be washed away, leading to uneven feeding. At the same time, this surge of soft growth creates ideal conditions for fungal diseases and can even encourage weeds.

If you are overseeding, over-fertilizing is especially problematic. High nutrient levels can inhibit seed germination and cause existing grass to grow too quickly, shading out new seedlings before they have a chance to establish. For the best results, it’s far better to take a gentle approach to lawn care in spring. I advise you to take your time and do what’s needed as it’s needed. Follow these four steps and your lawn will thank you for it later.

1. Weed Your Lawn

Without being overly dramatic, early spring is a crucial time for tackling weeds in the lawn. Get rid of them now and you may well be free of weeds for the rest of spring and into summer too.

This weeder from Amazon will make light work of a lawn that’s become over-run with perennial weeds such as dandelions, plantain and creeping buttercup.

Larger roots will leave vacant plugs of soil in your lawn, which are best filled with garden compost, topsoil or a specialist lawn mix like this one from Ace Hardware. If your lawn has a tendency to compact, add sharp sand to aid aeration.

Not too bothered by the odd daisy, buttercup or dandelion in your lawn? Then know that you’re in good company, joining a growing band of biodiversity champions.

Dandelions are one of the best plants for early-spring pollinators, which will thank you for leaving them nectar-rich treats at a time when food sources are scarce. Simply deadhead, or mow, your dandelions before they set seed and they won’t take over.

2. Remove Moss and Thatch

Let’s face it, few lawns are perfect, and most contain at least a little moss or thatch. But what exactly is thatch and how do you dethatch a lawn?

This mixture of decomposed and partly decomposed grass clippings, roots, stems and rhizomes is actually beneficial when it’s less than half an inch (1-2cm) deep, as it brings with it insulation and protects the soil from compaction. It’s this thin layer of thatch that helps to give a lawn a soft, bouncy feel.

If it builds up, however, as a result of too much fertilizer or poor soil conditions, it can stop water and nutrients from reaching the soil and your lawn, encouraging diseases and moss growth.

A small word of warning: if it’s early in the season and thatch is a big problem, give your lawn a couple of weeks after its first cut before you tackle the thatch as it can be a heavy-duty job and you want that grass to be strong and thriving before you go in with a solid rake (you can get a specialist thatching rake from Lowes).

If there’s just a little to be dealt with, then rake it out by hand with a fine metal-tine rake like this rake from Lowes.

3. Re-cut Lawn Edges

The edges of your lawn, where they meet flower beds and borders, can be looking uneven and weathered in spring.

Early spring is a good time to straighten them out and give them the definition they need to shine – again, as long as the soil’s not overly waterlogged. For nice crisp cuts, a sharp edging tool is what’s needed here.

For straight lines – and those inclined to pinpoint accuracy – bamboo canes and a taut line of twine will help you to achieve perfection.

You can shop edging tools at Lowes.

4. Feed Your Lawn Gradually

Provide a steady and consistent supply of nutrients now, without overwhelming your lawn or causing fertilizer burn.

Use a balanced, slow-release fertilizer, such as the Andersons fertilizer with micronutrients from Amazon, which will kickstart new growth steadily.


As with so many gardening jobs, successful lawn care hinges on timing. So get to know your wider area and, within it, your backyard, and its microclimate, then act accordingly. If it’s still wet and cold, hold off a while before tackling jobs like mowing and reseeding.

Once your lawn is showing signs of life, you can begin to give it the care it will thank you for after a long, wet winter in dormancy.
