Raised garden - soil composition

rayonline_tm, Sep 29, 8:15pm
Hi all

We finally built our raised garden. I have searched the internet. They say use garden soil then compost and mulch. Mitre 10 on Youtube said use green waste then Tui Vegetable Mix.

What do you suggest? We only have the Bunnings $3.50 green colour wording compost.

Cheers.

nothing wrong with the Bunnings compost. I used whatever garden soil there was, paper and compost. I usually put pea on top. I do have to top mine up with a bit of (Bunnings) compost every year.

cardboard or thick layer of newspaper in bottom to stop any weeds
layer of pea straw (not Hay)
home made compost, mulch etc- horse manure if you can get;
let it settle down
top with vege mix - it will take a lot to fill the raised bed
have had 2 beds for veges approx. 4 years, works well

we have several wodden raised beds that |I designed. They are simply filled with potting mix and as long as we keep the fertiliser topped up, they work perfectly. Our normal soil is very sandy, I think the potting mix, as long as you get a good quality one, is perfectly fine. Just keep away from the number 8 brand.

There is no garden soil at all. The area the ground is granite so we just built the raised garden along the fence.

I went to Mitre 10 and was told that I could get the $14 bags of garden mix which is expensive so was suggested to go to a landscape place with a towbar and get some top soil to go with my compost. We needed 28 bags.

The guy at the landscape place said to mix the topsoil with compost together. Is this right or do we layer them with topsoil and then compost on top?

Cheers.

For my vegetable beds I started with rotting straw. Then a good layer of seaweed which broke down really well over the winter with the frost. Lawn clippings, more rotting straw - anything I could get my hands on really! Then I went to local landscape supplier & got a vegetable garden mix - superdirt type stuff - sawdust, mushroomy mix, some rotted manure (wouldn't be surprised if horse manure because I had a bit of clover coming up!) etc (this is Gore local) works great.

Raymond I think mixing the soil and compost would be fine to start your garden off, then add home-made compost and manure to the surface near your plants whenever you have it. A barrel of fermenting liquid fertiliser (fish scraps, seaweed,manure) would also be useful.

Our raised gardens wer filled with 6m3 of topsoil and about 3m3 of "mushroom compost". Mixed and delivered in a single load by truck onto the street, which we wheelbarrowed into the back. In the rain one Friday night.
It's still promoting good growth several years later.

Use a maximum of 1/3 compost in your raised garden. The rest can be a general soil mix. such as 'garden mix', top soil or even outdoor potting mix.
