Shaping your very own haven

Your garden is your sanctuary. It’s a place for rest and play. But it’s also your where you can set your creativity free to shape and recreate your surroundings.
No matter if you’re going for a luxurious orangery or aiming for the healthiest lawn, we’ve got your back with tools and experience you can rely on.

 

Renovating the lawn

When the weedkiller doesn’t bite and the brown patches take over, it’s easy to start doubting if your garden will ever look the same. But there’s hope. You can always start over with a lawn renovation.Lawn Mower

How to do a soil test varies in different parts of the world, but commercial labs generally do it. The lab will provide you with a detailed mode of procedure that will be helpful when you move on with your renovation.

1. Decide when to renovate


Renovation season varies depending on where in the world you live, but it’s important to make sure that the ground is warm enough for the seeds to germinate and grow. That means that the ground temperature should be at least 10° Celsius.
“One rule is to wait until after the first cut of the season, when the lawn has turned green and you know that it has started to grow,” Karlsson comments.

2. Determine the reason for lawn failure


If you work out why your lawn has deteriorated, you can use that knowledge to make the right decisions during your renovation. For example, if the lawn has thinned out due to growing trees that shade the lawn and compete for water and nutrients, you should select shade-tolerant grass varieties. You might also want to prune some of the tree limbs, opening up for more sunlight and rainfall.

“You can get some information by just looking at the lawn, but I definitely recommend to do a proper soil test,” says Karlsson.

3. Remove weeds and thatch


Start the actual renovation by removing weeds – especially the perennial ones – manually or with a herbicide. This keeps other species from competing with your new grass. If you use herbicides, be sure to read the labels and follow the instructions. Most products will allow you to seed in seven days, but some weedkillers will keep your seeds from germinating for three to six weeks.

Check your thatch status by digging up a small plug of turf, several inches deep. If the spongy layer is more than three quarters of an inch thick when you compress it, it’s time to have your lawn dethatched. If your lawn is larger than 300 square meters, you would want to use a power rake or a vertical mower with a scarifier. For smaller lawns, a manual thatching rake will do.

4. Prepare the soil


Apart from using it for thatch removal, a vertical mowerRider with a scarifier can be used to prepare the seedbed for new seeds. Go over the entire lawn with the tines set to nick the soil surface to a depth of approximately 1/8 to 1/2 an inch and then rake the large clumps of debris from the site. Another way to prepare the soil is to do an extensive aerifying. If you choose this method, you need to go over the entire lawn 3-5 times to make it completely aerified. However, the very best result is achieved by doing both of the above: aerification followed by vertical mowing. This will strongly improve water supply to seeds and emerging seedlings.

“A soil that’s too dense or the ground is too hard are common problems for landowners. It makes it hard for water and oxygen to reach the roots of the grass plants, which leads to poor growth. An aerator creates ways into the soil for the air and water and a vertical mower with a scarifier splits the grass plants, leaving you with more plants and a thicker lawn.”

5. Water your lawn


Grass seeds and seedlings need water to germinate and root. Your ground doesn’t have to be soggy, but make sure the soil is at least moist. If the lawn feels dry and the chances of rain are low, start building a reserve of water in the soil by running the sprinkler for an hour or two a day several days prior to seeding.

“To keep your lawn evenly supported with water is very important. If you do that and the ground temperature is decent, you are well on your way”, Karlsson points out.

6. Use a fertiliser


Fertilisation will encourage establishment and growth of your new seeds and seedlings and should be done just prior to seeding. Apply a slow-release nitrogen fertiliser. If you’ve done a soil test you’ll know if your lawn also needs additional phosphorous and potassium.

7. Seed


When your lawn is in relatively good condition, you can use the seed mix you used in the past. If you’ve done a soil test, you will have a good indication of which seeds to use.

You can spread the seeds by hand, but if you want to make sure that the seeds are spread evenly, the best thing to do is to use a spreader.

“Some spreaders can be connected to your scarifier. I would recommend a centrifugal spreader,” adds Karlsson.

8. Enjoy


“There is no need to wait a certain amount of time before you start enjoying your newly renovated lawn. When you’ve overseeded it, you can start using it right away, mowing it as you normally would,” says Karlsson.
