Top dress: Not just a nice compliment!
As I mentioned in our previous post, top dress is a way to help supply nutrients to your lawn after dethatching, or just giving it a healthy dose of nutrients in general. But what is top dressing? Follow along, and it might prevent your lawn becoming a pain in the grass!
Top dress can be a light layer of either sand or some form of composted organic matter. Sand is a terrific way to counteract thick clay soil, or if your lawn is uneven. Top dressing with sand is a fantastic way to improve drainage and loosen your soil density, however as sand doesn’t have a lot going for it in the way of beneficial nutrients, using a quality liquid or granular lawn fertilizer will be your ‘go to’ for nutrient introduction. Yellow sand is the medium of choice due to its fantastic drainage and porous properties. This is the main reason it’s used on man-made terrain like golf courses.
Compost on the other hand is a fantastic choice when it comes to top dress mediums. It’s rich in all the nutrients that your turf needs for healthy growth. Your lawn will absolutely thrive with a top dress of organic compost, provided it’s finished breaking down and had some filler soil mixed in. If you are using your own compost, and are unsure if it is ready to use, here’s a helpful hint: if it still looks and smells like rotten fruit and vegetables, and not have a consistency of soil, let it sit for a little bit longer until the material has completely broken down.
A composted soil mixture will help improve clay like soil and help the more sandy soils retain more nutrients and have the added benefit of attracting good microbes to your lawn.
Topsoil is an available option for use as a top dress, however your yard may suffer slightly from a lack of proper minerals that your grass needs to stay green and lush.
The last option (and the best choice for top dressing) is customizing your own top dress mix. It can be more economical, and you can tailor make your mixture to suit your lawn's needs. The most popular combinations use compost as a base blended with either sand or topsoil. A good mix of sand, soil and compost is an effective way top dress your lawn, while preventing the creation of puddling spots which can kill off parts of your lawn.
Whichever choice you make, it all comes down to how much do you need? For a typical lawn, anywhere between 3mm and 12mm coverage more than enough, and only needing to go thicker if your thatch is particularly bulky (but if you followed our previous post, this shouldn’t be an issue).
Now, here are the things you will need to apply all that lovely top dress to your lawn.
• Rake (or a spreader rake)
• Wheelbarrow
• Top dress mix
• Aerator
• Shovel
Provided you have followed our dethatching guide, your lawn should be ready to go. Rolling an aerator roller over the area will help improve your results here.
In the same way you would swing a tennis racket in a backhand fashion, start by flinging your top dress mix around your yard, aiming for that 3mm to 12mm coverage.
Once you have your light coverage laid down, use your rake (or if you have a spreader rake [it has a swiveling head and rollers instead of tines]) to spread the mixture around as evenly as possible. Once this is all done, give your yard a good watering, and it’s all done!
I’m sure you’re asking if you will see immediate results, however, I’m going to burst your bubble. If you maintain a consistent watering habit, you should start to see all that arduous work and effort beginning to pay off after 2 weeks.
One last thing is how often top dressing should be done. Good news is that you only need to do this every few years at the start of Spring.
