I have this lawn (mainly weeds) and red soil (clay type) I am going to be aerating, over-sowing and top dressing next week and have a few queries, so I'll tell yous how I think I'm going to do it and yous can tell me if it will work. #1 I am going to apply a selective herbicide to the area to take out the weeds #2 Apply a liquid gypsum to the area (one of the good ones with a high calcium content. #3 wait for the herbicide to kick in and scalp cut the area. #4 Aerate the area #5 spread a seed (couch) and seed starter fert mix. #6 Soak the area with water. #7 Spread a top dressing mix with lots of organic fines in it at around 1/8 of an inch (Is that too thick????) #8 Set up a temporary Irrigation system and let it do its thing. I'm thinking this time of the year down here germination time will be 8 - 12 weeks (pretty hot down under) I was thinking that the temp irrigation system might get stolen? Has anybody had any experience with thieves and temp irrigation systems? ......................Any solutions???? So there you go.....................sound like the go??.............or not??
