Depending on what you’re growing, we can blend ingredients in the right proportions.
Potting soils are for planters, hanging baskets, window boxes and other containers where drainage is important and weight would be a problem. Potting soils allow excess water to quickly drain out the bottom of the container by gravity, pulling in air to replace the water.
The topsoil you find in woods contains lots of rotted vegetation. Topsoil in farm fields has been turned over, mixed and often exhausted by repeated plantings. Topsoils often contain clay or composted manure. They also contain weed seeds, soil bacteria and fungi.
What is the difference between topsoil and potting soil and which one should you use? That depends on what you’re using it for.
First, let’s understand what we mean by the words topsoil and potting soil.
Because plants breathe through their roots, they’ll thrive in potting soil as long as they are watered regularly. Some potting soils have moisture crystals, bits of polymer that help keep them from drying out so quickly.
For raised beds, topsoil is much cheaper, as it’s sold in bulk, but it should be mixed with compost, peat moss or vermiculite to make it fluffy and improve drainage. Otherwise, it will pack down, swell and break your raised beds.
Sounds like the weed seeds were already in the soil, although some may of landed recently form elsewhere.
Its normally best to go for screened topsoil as this is relatively weed free and good quality.
i took delivery of a large quantity of topsoil and placed it in a border that had the existing shrubs and soil removed. I had to leave it fallow for 3 weeks thanks to a bad back(!) and now it is covered in weeds. Is this just nature taking its course or was the topsoil contaminated and I have a claim against the topsoil provider?
Did the company mention it was weed free in any writting or on its web site? if so then you may be able to get something back from soil provided.
If it advertised it as just topsoil, then there was no reference to it being weed free, they were just advertising topsoil, so probably cant claim anything back.
Try removing some soil from the undisturbed area (trying not to mix surface soil in, and do a few sample across the bed) about 4-6 inches down and putting it in a pot and leaving it some where e.g conservatory (possible not a greenhouse as this is a bit open to elements) where NO seeds can land in it.
Weeds will grow anywhere even in soil in the house provided light and clean water can get to the sample. As its been undisturbed for 3 weeks, in theory if the soil is 'clean' then there shouldn't be any weed grow in your sample from below the surface. If you do get many weeds then it may be that the soil contained them already.
