Triple mix composition and usage
Our triple mix contains 1/3 topsoil, 1/2 compost, and 1/3 combination of horse and chicken manure. It means our triple mix is natural topsoil fortified with natural components improving its fertility, water-retaining capacity, and air permeability.
Use it for lawns, flower beds, fruit and vegetable gardens, or when replanting seedlings.
The triple mix is NOT intended for potting. Therefore, it is also NOT recommended as a component of potting soil.
Concerning the suitability of the triple mix for vegetables, you have to check it for each crop you will grow. Some plants thrive on manure-containing soils (like onions), and others (like blueberries) do not tolerate even small amounts of manure. Most are somewhere in between. For manure-sensitive plants, it is safer to use triple mix in the fall time, as a significant part of the manure can decompose till spring.
If you are not sure about how good manure is for a particular plant, then use topsoil and add to it everything the specific plant requires. If you don't know what the plant needs, add a little bit (better less than more) of universal mineral fertilizer or add nothing, as our topsoil is pretty fertile.
Concerning the source of our topsoil, it comes from different places. For example, when excavating for construction, they take the upper black soil layer off. This soil is screened and used as garden soil or for making the triple mix. The soil can also come from a farm. It is hard to know where a specific lot of soil comes from.
If you are not sure if our topsoil is good for growing your food, you can gradually create your healthy fertile soil by adding organic fertilizer. One of the ways to create organic fertilizer is composting your food and yard waste. Another option to fertilize your soil organically is with growing green manure and cover crops.
So far, nobody complained about our topsoil.
Are there any weed seeds in the Triple mix?
The triple mix contains natural soil, hence weed seeds may happen in it. It is possible to kill weed seeds in natural soil by heating the soil to high temperatures. But this way, you also kill soil microbial flora that plays a crucial role in natural soil fertility self-regulation; such soil turns into a mechanical mixture of dead components. It is not a living thing anymore. You can grow plants in it, but such soil will need more care from you. Another way to kill weeds: using herbicides leads to environmental pollution and even poisoning insects, humans, and animals. For a private lot, weeding and mulching are preferable. Also, consider planting your cultural plants a little denser, so the weeds don't have space to grow.
