Just when you mix the compost through the clay don't mix it deeper than 100mm if poss. The Reason is compost doesn't break down correctly with 200mm of soil on top of it and it could kill the lawn. Don't have to be mm accurate but best you can do. You just don't wont compost deep in the soil as it needs air to do it's thing.. The Soil profile (top soil downwards)would be 100mm sandy loam 100mm compost/clay/gypsum* mix 100mm clay/gypsum* mix Anything will grow in this, you could do your whole block so when you want to plant in garden beds they are ready to go.. I am from north west Sydney where there is a lot of heavy clay soil. I keep returning to this brilliant thread by Kyeo and BK with golden advice about preparing heavy clay soil for turf. I have read it several times as my understanding of soil prep has increased and it makes more sense each time. Thanks BK!! OK, so I am now officially hijacking this thread... In my situation, I have non dispersing clay (did the dispersion test), so my 2 sacks of gypsum will likely be on Gumtree some time soon So, I cant have that 3rd 100mm layer of clay/gypsum. So tell me would this work (on a high traffic play lawn (100sqm) and the nature strip 200sqm): 1. excavate so that we are 125mm below paths. dispose of the soil 2. rip 100mm of clay, add Powerfeed and some certified organic compost (or should I leave out the compost, seeing PF is a liquid compost) ? 3. Add a 100mm layer of sandy loam as a top layer 4. lay the turf 5. In warmer months, hit the turf with PF and do mulch mowing What have I missed ? What about a wetting agent (seamungus ??) in the top sandy loam layer ? They using concrete or timber sleepers? Timber or steel uprights? Any drainage behind sleeper? 3 5881 the leaves that are now underground go yellow, the tips that poke through photosynthesise and have chlorophyll, same reason they grow rhubarb in the dark. 5 4870 Versaloc is a mortarless besser block system that still needs a properly engineered footing. If you just do a 400x200 footing it will fail in time. At 17m long you need it… 1 17885 |
