Spring lawn care: A Guide

Spring lawn care: WHEN TO RAKE LAWN AS the new season starts

In lawn care terms, spring means a new year. When it starts to get warmer, you know it’s time to start your spring grass care schedule again – after all, that long snooze through the cold season means your lawn is hungry! But before you can fertilize your lawn in the spring, it needs tidying up. That means raking to gather up all the leaves and broken twigs that have accrued on the lawn since it was last cleared. The amount of care you need to put into spring lawn maintenance also depends on its condition: is there moss and thatch? Does it contain a lot of dead grass? If so, it may not be enough to just mow your garden before the spring lawn feed – you may also need to scarify it.

Spring lawn care: How can I make my lawn look great?

The first step to achieving a healthy lawn is clearing it thoroughly as part of your spring lawn preparation. Any leaves and twigs can be removed with a rake – or to take care of the job in no time, a STIHL leaf vacuum may be helpful here. Repair any lawn damage caused by cold weather, fertilize the lawn, and renew bare patches by overseeding for new growth.

Level uneven soil

Once you’ve got the twigs and leaves out of the way, the next step is smoothing out any uneven ground – a straightforward spring lawn care task that just needs a shovel or a rake. Break up the soil on higher areas and spread it across the lawn; grass will grow through the bare patches again within a few weeks, or you can overseed the patches for new grass, to be on the safe side.

Make sure the lawn is ready for mowing

The next spring lawn care job is to loosen the soil where necessary to prepare the lawn for mowing. The grass needs to be completely dry before you mow it, so if you see persistent standing water in places, it’s particularly important to loosen the compacted soil in those spots so that the water can drain away – just drive a fork into the ground a few times and move it around.

Spring lawn feed

If you did not consistently mulch your lawn throughout the previous year, it is likely to be suffering from a lack of nutrients and so will benefit from a spring lawn feed. Fertilization in spring is part of good lawn care, and helps the grass to grow strong, healthy and green. It’s generally sufficient to fertilize the lawn twice a year – once in spring and once in late summer, though you may also opt for an additional round of fertilization between those feeds, perhaps in June. Organic and mineral fertilizers are available in liquid, granular and soluble form from any garden care centre or DIY store, and you will even find special spring fertilizers which are formulated to help the grass regenerate early and to strengthen its weakened roots. This is also a great time to overseed any patchy lawns, as the fertilizer will support the new grass once it germinates – though we would recommend aerating and/or scarifying first for best results.

Fertilize your lawn to beat moss

Moss is an indicator plant for nitrogen levels, so it will spread quickly through your lawn if the soil is short of this nutrient in particular. Well-fertilized lawns suppress moss by means of vigorous grass growth, which is why including a spring feed in your spring lawn care schedule is a great long-term method for controlling moss. However, if you’re dealing with a lawn that has been neglected to the point that the moss has almost completely overtaken the grass, the first stage of spring lawn treatment is to tackle the moss by scarifying the lawn, and then to start regularly fertilizing your lawn in spring.

Spring lawn care: feeding tips

• After applying fertilizer according to the instructions, water the ground well to ensure that valuable nutrients can be distributed throughout the soil.
  
• If there is a lot of moss and weeds among the grass, you should first scarify the lawn (though it’s best to wait until late-April, when it’s a bit warmer), and then apply a spring feed.
• A fertilizer spreader will ensure even distribution over the lawn.

WHen to mow lawn in spring

As soon as conditions get warmer and the soil has reached around 10°C, you should start the spring lawn care schedule of mowing the lawn at least once a week, though we recommend mowing twice a week during peak growth periods. It needs its first cut of the year now, to promote dense growth. Mid-March to mid-April is generally the best time to give the lawn its first cut – though a mild winter could mean the lawn needs mowing earlier in the year.

When to cut grass in spring

The spring lawn is in a growing phase again and your garden is dry; the next lawn care step is to make the first cut, known as the cleaning cut.

• Make sure that the blades on your lawn mower have been cleaned and sharpened. This means the soft, young spring growth is cut cleanly, rather than being damaged in a way that makes the grass susceptible to disease.
• Consider the length of your lawn. The optimum cutting height is between 4 and 6 centimeters; in shaded areas such as under bushes, it should be at a height of at least 5 centimeters.
• The effortless central cutting height adjustment on your lawn mower makes it easy to set your preferred cutting height.

Give your lawn mower a spring inspection

• First check your mower’s general condition, taking care to ensure there is no damage to the housing, wheels or blades.
  
• If the blades are blunt, have them sharpened and balanced.
• For petrol-powered lawn mowers, change the oil in spring if you didn’t do it at the end of the last season, in order to remove any debris from wear. This lengthens the service life of the engine.
• You should also check the air filter of your lawn mower’s petrol engine: if it’s dirty or clogged, it needs replacing.
• In cordless lawn mowers, check the battery level and charge it fully before getting started on spring lawn care.

Fertilize your lawn while you mow – in a single step

Make spring lawn care simple by mowing and feeding your lawn in one go, using a STIHL mulch mower or the iMOW® robotic mower. These shred the grass clippings into small particles which are distributed across the lawn as you work, functioning as a natural green fertilizer. The nitrogen in the clippings is mineralised in the soil, which keeps your lawn nourished and happy.

Do I need to scarify my lawn?

Scarifying is simply the process of using a tool to clear matted grass and moss from the surface of your lawn, exposing the soil to improve growth. Whether you should include scarifying in your lawn care depends on your lawn’s condition. To check, pull a small metal rake gently through the turf before you start your spring lawn care: if it picks up old grass clippings, weeds or moss, this may indicate inhibited lawn growth. This is particularly common in heavy soils that are low in oxygen and become easily waterlogged; shade can also have a negative impact on the structure of your lawn. Scarifiers with blades do a great job, or you can achieve similar results by putting some effort into careful raking of your lawn.

Tips for liming your lawn

You may wish to add a liming step to your lawn care list in spring, to help avoid moss and matting the next year by adjusting the pH of your soil. You can buy a simple soil test to confirm your exact conditions; for grass, it should ideally be at a pH value of 6.0 to 7.0, with a lower value indicating acidity. Adding lime helps to alkalize the soil and regulate pH for the longer term, deterring moss and other lawn weeds in the process. Because lawn soils tend to become more acidic over time, applying lime annually in spring can be a valuable lawn care supplement until levels balance – after which it can be reduced to every few seasons. Mow and scarify first, then after applying lime you should let the grass rest for at least a week.

Summary: lawn care in spring

• Remove leaves and twigs from your lawn in spring
• Expose the soil surface using a rake, then leave it to dry
• Starting in March, complete the first cleaning cut
• It’s important to mow regularly after the first cut, ideally on a weekly basis
• Use specialist fertilizer for a spring lawn feed
• Lime and then scarify your lawn, to help prevent the development of heavy matting and weeds
• Aerate your soil to boost circulation of air, nutrients and water to the roots of your lawn
