i go to some riverbeds where i have found some rich soils mixed with a little clay, mix with peat moss and vermiculite, some slow release fertilising chemicals and topped with some animal excrement and bobs your uncle.

bump.
I'm surprised (bulk) potting mix recipes don't seem to be on this forum (according to my search anyway)

I've got new pots galore (pots r us como closing down sale) but it will cost me quite a lot to buy retail potting mix to fill them.

I'm sure you can change the recipes for different plants, but does anyone get their (bulk) potting mix more affordably (without digging up river beds)?

Brad

PS I've got 4x40cm pots, 2x30cm pots, 2x even bigger concrete pots, so I need around a half a cubic metre or 500L or 16-20 bags

Why don't you get some at the Good Soil , I am sure there is a franchise near you.
a cubic m3 is only 38 bucks of good garden mixed soil(got composts, fertilizer,great top soil, & peat and vermiculites and a bit of sand)

Don't need to go and dig up some river bed, hehehehe. Or any of those bagged potting mixed.

Hi Tigerbalm,

I find that Debco organic potting mix is the best. It is a bit pricey at about $13.00 for a 25Lt bag but the stuff is wonderful.
I buy mine from Bunnings
If you actually take a good look at it, it looks quite different from the cheapo potting mixes that you can buy.
I think your fruit trees will reward you for buying a good mix and will perform much better.
Remember that you have to change potting mix every 2 years (I think it's 2 years).
Happy growing !

thanks ellen. I will look at local soil suppliers (never heard of that name) - but even then - I'm curious what should be in the mix or what the tricks are to find it cheaply. $38 would be brilliant

for reference for those that go looking - in Perth a m^3 of bulk unfertilized potting mix can be picked up for between $93-$100 depending on supplier. This works out to about $3 per 30L bag. (The cheapest bags of decent mix I could find were $5)

The one I got seems a finer than the bagged stuff (maybe more coarse sand less large woodchips)

I prefer Miracle grow potting mix for my vegetable farming. I always bought from https://www.bestbloombooster.com/is-miracle-grow-potting-soil-safe-for-vegetables/ It is also best for fruits and seeds. It has three major contains nitrogen, potassium, and phosphorous. It all had valuable features like it keeps your plant leaves the green, gives nutrients, maintain straightness of roots.

If you are using a potting mix with lots of organic material such as bark, peat, soil, compost they will eventually break down and the result is poor drainage. So if the plant is going to stay in the pot for a long time, or if it cant tolerate wet roots, then you need to mix in some coarse pumice that is about 4 to 7mm particle size. Also a similar grade of perlite may be useful. They will help with aerating the mix. For my tropicals I use it all the time and it makes a huge difference in plant health and survival. I guess using about 10% of the pumice but havent actually measure , I just use my eyechrometer.

Hi Brad, there is a textbook re potting mixes, Growing Media for Ornamental Plants and Turf by Kevin Handreck and Neil Black. It will answer most if not all your questions.
