That's fine, put whatever sand and rubble you have at the bottom. The top soil needs to be a minimum 300mm deep from the top edge of the planter. 400mm is better. You can fill the planters top to bottom with imported soil of you want. Below 300mm from the top edge is basically just drainage and doesn't need ammendments.

Would this work if I fill up the whole planter box with it? https://www.soilsaintsoils.com.au/Our-Products/Soils-(Perth-metro-prices)/Landscape-Mix.aspx So there is no need to add Zeolite and Bentonite?

Yeah should fine, the vegie flower mix does sound a bit better balanced though, it has actual loam (clay bits) in it. So does the native mix. The landscape mix has some sort of fertiliser added which isn't really needed at this point. Just because it's popular with trade doesn't mean it's great long term.. Zeolite and bentonite are needed when amending the basic sand soils found in perth. An imported blend that has clay in it will do just as good job. Btw 'Loam' soil is a combo of sand and clay basically. There should be some threads here where there are recommended perth soil suppliers. Re: What soil do I fill my planter box with? 9Dec 20, 2016 4:57 pm It's funny how every soil place I called up so far recommends a landscape mix. Also, when I asked them about a vegie mix, they mentioned that they are not suitable for native plants. Another also said that if I want some clay mix, I should look at sand remedy instead. And I can't seem to find the thread about Perth soil suppliers. This is starting to get confusing Re: What soil do I fill my planter box with? 10Dec 20, 2016 5:49 pm Just called another company(which I read about on this forum from a thread), which sounded a lot more "knowledgeable" and definitely more detailed - http://www.greenlifesoil.com.au/ Based on what he recommended me, I think I will be doing the following: 1) Leave 1 course of brick from top empty. 2) Then fill between 50 - 100mm of mulch depending on the height of the planter boxes. He recommended this mulch. 3) Then fill 300mm with a good top soil. He recommended their General mix. 4) Then fill the rest of the box at the bottom with a cheaper soil which is their Fill Soil which is also a pretty rich soil as they are the leftovers from the various soils mixed together. Sounds good? Only issue I have is their soil is definitely more pricey than the usual stuff. Maybe cause it is organic? What soil do I fill my planter box with? 11Dec 20, 2016 8:39 pm Yeah it confusing for the consumer. The perfect soil growing landscape plants is 'loam'. Loam has sand, clay and other minerials/organics. It holds water but also drains and allows easy root penetration and doesn't compact like normal clay soil. Loam soils range from sandy through to clay loam. A 'loam' is the soil you want. Landscape soil suppliers are pretty vague on the exact % in their soil blends. Hence just they say just use the landscape mix. My bet is the landscape mix is just sand mixed with organics and manures. 2 4350 yeah i couldnt picture it issue either, but i could clearly picture what they were doing wrong haha 2 5295 If you're in a flood zone, not only are you dealing with the importation of fill and laying it down in 150 lifts to achieve compaction, you're going to have to consider… 4 5532 |
