Blonde peat is the backbone of most professional growing media: if you produce seedlings, pot on young plants or formulate custom mixes, you have almost certainly worked with it. But what exactly does it do, when should you prefer it over black peat, and which grain size should you choose? Let’s take it step by…
If you grow professionally — vegetable transplants, ornamentals, soft fruit, young plants — sooner or later you ask the question: who are the leading professional substrate producers in Europe, and how do I pick one? Here is the direct answer: a leading producer is not defined by size or by a ranking, but by five…
Expanded clay is probably the best-known drainage material: those light, brick-coloured balls you find at the bottom of so many pots. But its role goes beyond “putting some at the bottom”. Let’s look at what it actually does, how to use it for pots, drainage and hydroculture, and when it’s the right choice over other…
Volcanic lapillus often shows up on the surface of a pot or at the bottom of a planter, yet its role is rarely explained. It does a precise job: it gives structure, drains, and protects the substrate without breaking down over time. Let’s look at what it actually does, which plants benefit from it, and…
Vermiculite shows up in countless substrate recipes without anyone ever explaining what it actually does. Yet a handful of expanded vermiculite in the right place changes how a seed tray holds water, or how a young root system finds air and nutrients. Let’s look at what it’s used for, when it’s worth adding, and how…
When you choose a professional substrate, you rarely read how the peat at its base was harvested. Yet the extraction method decides much of how the substrate behaves: how much air it holds at the roots, how well it drains, how consistent it is from one batch to the next. The two main routes are…
If you raise plants from seed — vegetable transplants, ornamental plugs, young plants for grafting or potting on — you already know that sowing is the stage where the wrong substrate costs you most. Uneven germination, one too many cases of damping-off, a plug tray that dries out in patches: those problems follow you through…
Blueberries are one of the crops where the substrate decides the outcome. They’re calcifuge plants with shallow, fine roots that demand an acidic, airy, consistently moist medium — conditions field soil rarely offers. That’s why so many professional growers raise blueberries in pots and containers: it puts the root environment under your control. This guide…
If you build or maintain turf, sports pitches or landscaped green areas, sooner or later you run into the word top soil. It’s used a lot and defined rarely — and the gap between a good top soil and a poor one shows up in establishment, drainage and the uniformity of the sward. This guide…
Seeding, rooting, vegetative growth and flowering have very different needs. What to look for at each stage to optimise production.
