Hello! Does anyone here make their own soil mixtures without purchased materials? If you look for home made soil, its usually just a mix of bought ingredients like peat moss, coco coir, perlite etc. Peat moss is fossil, coco coir and perlite is certainly not from around here so definitely transported long ways.

Now, I’m no gardener but I can see that all the native plants around me don’t have any of that luxury, yet they thrive. Compost is the next obvious answer, but if you haven’t yet had time to establish one, what options are there?

I’ve successfully grown plants like tomatoes, strawberries, herbs and salad in a mix of gravel, local manure, topsoil and rotted wood.

I am looking for recipes and information on such mixes as I often struggle with drainage which killed my cucumbers. I need huge amounts of gravel to keep the silty manure from clogging up my pots but 3kg pots become quite silly too and the gravel makes repotting an almost sure death to any roots I want to move.

What are the consequences of using uncomposted organic materials? Some gardeners say soil acidity usually solves itself through microbes, yet the common saying is that it must be composted first.

Happy gardening Cheers

Horse manure (with or without straw/sawdust) is relatively easy to source (most horse places are happy to get rid of it) and can be mixed with wood chips (ratio ca. 50/50 just for a ball park value) for immediate planting. Most plants tolerate it well and it will turn into soil to be reused with more manure and wood chips in the future. Even if compost or more complex mixtures would be slightly better in theory this is absolutely worth doing for the immediate availability and ease. Two ingredients, and so far we've had sweet potatoes, beans, strawberries, tomatoes, turnips, carrots, beets, rhubarb, aromatic herbs, sunflowers, squash, cannabis and more

You can add wood ash (not too much, strong pH change!), charcoal (no worries, the soil loves it), organic kitchen waste (no need for a separate compost, just bury it in your soil mix!). But no need for any of this. You don't even need raised beds. I've grown in bags, large and small pots, in makeshift raised beds (metal grid and cardboard structure) and on no-dig soil (just dump on the soil, your soil life takes care of the rest).

I see too many people work in their garden with old-timey ideas of the hard work a garden needs and how it should look. Instead of sweating and getting frustrated you can always choose the shortest path, the fewest steps, the most uncomplicated solution. Never mind the aesthetics, it will look pretty once it grows. Don't forget to water!

Sounds close to what in doing, but with cow manure. Im very paranoid about bringing spanish killer slugs which are abundant all over Sweden, but we are one of the few areas that don’t have any. So the only external material is from my neighbour, who also don’t have slugs.

But my problem with the manure is drainage, which is what prompted this question. On the no dig garden its fine when mixed with whatever, but for things that live in pots it just turns to muck and takes hours to drain. Based on your information i will try a significant increase in wood chips tho.

Thanks for chiming in!
