This is a subject that’s very important for your garden as certain soils and plants will not do well together. Remember to do your research when choosing which plants you will want to grow, as some plants require well-drained soil and other plants will need more water retention.
In Central Alberta we generally have clay or silt, there is not much in between, which means we need to add amendments to the soil. Amendments can come in many forms; sand, peat moss, compost, perlite, or manure. All will help to develop long term, excellent soil conditions.
Please note that amendments do not give the plants the NPK (fertilizer) they need, but it helps plants get those nutrients. So although compost is great for plants, it’s more for amending the soil to give it the conditions required for plants to get those extra nutrients vs. just giving the nutrients itself.


So, you have clay, what will help?
Let us look at the long-term goal of the soil development. Ideally you want soil that can allow air circulation but will also hold and drain moisture. Sometimes this just means digging out and starting fresh with a new mix of soil, other times that will mean adding to current soil to increase the desirable conditions.
Clay will hold water, but it is also very hard to dig in. Adding sand and compost/manure will help to loosen it up. Whereas silt, just by adding compost/manure, will help to give it density, and peat moss will help with water retention.
Learn what your soil is like now and then research ways that you can increase or benefit it for your plant’s growth. This is not the same as pH (measurement of how acidic/basic water is), as that is a whole different topic, but this will get you to a point where you can then balance your pH levels in the soil.
