Thanks Jason for the welcome. I'm so happy I've found this blog as I'm just starting to really get into gardening so I'm sure I'll have lots of questions and maybe one day, I'll even be able to provide others some answers
Hi Jason and everyone
our lawn has been too wet and, now that we’ve fixed our water problem, we want to regrow the grass. There is currently very little grass but lots of moss and dandelions. Should we spray first to kill the weeds and then top dress? There are lots of bare patches. We live in Melbourne and the area is shaded from the East and West. The area won’t get much traffic. Thank you!
Welcome to the Bunnings Workshop community @Moira. Many thanks for your question, I'd be glad to provide some advice.
It's great to have you join us and fantastic to hear you've fixed your lawns water issue. I would advise you to deal with the weed issue prior to top dressing as it is a simple process. There are a variety of selective weed killers available which can be sprayed over the area and they won't affect the grass that you will lay or sow. These products are in concentrated form and can be mixed up in a garden sprayer to be distributed over the area. Alternatively, there are products ready to use like Hortico 2L Bindii Killer Hose On which are suitable for dandelion and broadleaf weeds.
The moss can be killed by applying a mixture of 2 parts dish soap to 1 part water and spraying the moss until it is saturated. You can also physically remove the moss by skimming it and the top layer of soil off of the area. Make sure you get all the roots in the process or it will return.
Please let me know if you need further advice or had any questions.
