Spring has arrived! And with it, the need to spring clean your lawn. The first step in your Spring lawn renovation is to deal with any thatch build up.
So what is thatch? Thatch is a build-up of grass runners, stolons, rhizomes and roots. Over time it can make your lawn thick and spongy and will eventually increase the height of your lawn. As your thatch layer gets thicker, it will start to hinder water, oxygen and nutrients from entering the soil, causing issues with the health of your lawn.
And what can we do about it? Well, there are two ways to manage thatch. Hiring a dethatcher which will remove thatch AND most of your lawn very quickly, leaving just the roots and stolons. This can be a scary sight, but rest assured, with a bit of fertiliser and plenty of water, your lawn will come back better than ever.
A rotary mower will also do the trick. You must have sharp blades to cut through the thatch and a catcher helps with the clean-up. Dethatching with a mower is best done over a period of time by slowly reducing the height of your mower.
After dethatching, it is very important to keep up the water to your lawn and apply a good quality fertiliser to kickstart growth. You can also add a pre-emergent such as Oxafert to prevent any unwanted weeds from popping up while your lawn recovers. Oxafert will not kill existing weeds but has a key ingredient that prevents the weeds seeds from germinating.
You would think that after dethatching you wouldn’t need to mow for a few weeks but alas, mow you must! Continue to mow once a week during the recovery period. This will encourage your lawn to grow sideway fill in all those gaps.
Happy Spring renovating everyone!
