New homeowners often consider various home improvement task, including relaying their lawn. One of the most common question on gardening forums often is “Is it possible to lay new turf over the existing lawn?”. The other frequently asked question is “Can you lay grass on concrete?“. Well, there are various opinions on the topic and it all depends on whether you want a quick for, or to establish a healthy, lush grass.
Should laying new grass on an old turf be done?
The main problem with this job is that it can be difficult for the root system of your new lawn to grow in properly. Grass needs at least 6-8 inches of topsoil to be dug over before planting. Its roots need room to grow.
Following this, here’s what to expect when laying turf on turf:
New turf put down over old will probably grow if you water it well and maintain it. However, over time you might see a gradual deterioration in the condition of your lawn. This will be because as the old turf underneath dies off, the new turf will compact, making drainage and root growth difficult.
In fact, you’ll see this in any situation where there’s not enough room for the grassroots to grow down – newly built homes commonly have this problem. The builders don’t bother to make sure there’s a decent amount of topsoil before laying the rolls of grass down. The end result?
Grass that eventually stops to grow, withers and dies.
Will new turf grow successfully over old grass?
Laying new lawn on old turf can be a successful project. In fact, many gardeners in the U.S. seem to have found success when doing so. Some claim that simply rotovating the old grass and frequent watering can solve the problem…
But it’s really not recommended if you can avoid it.
If you have a professional on hand who’s willing to back up their opinion and their work with a guarantee, then by all means – consider the option. Otherwise, stick with doing things properly and properly remove the old and compacted turf before laying new sod.
