[citation needed] Peat is discouraged as a soil amendment by the Royal Botanic Gardens, Kew, England, since 2003. [32] While bark or coir-based peat-free potting soil mixes are on the rise, particularly in the UK, peat is still used as raw material for horticulture in some other European countries, Canada, as well as parts of the United States.
The use of peat is controversial since the harvesting of peat moss from peatlands (which includes unique habitats such as bogs and fens) can degrade these peatlands. Peatlands are home to a diverse range of plant and animal species. Peat also has a very slow accumulation rate, as little as 1mm per year, so they take a long time to regenerate.
Most of the time, gardeners refer to potting mix and potting soil as the same thing. But products labeled with the word “soil,” such as garden soil or topsoil, are meant for in-ground use only ...
John Innes compost is a set of four soil-based formulae for growing media, developed at the former John Innes Horticultural Institution (JIHI), now the John Innes Centre, in the 1930s and released into the public domain. The formulae contain loam, peat, sand, and fertiliser in varying ratios for specific purposes. These composts are used to ...
Around the holidays, you can buy them as single dry bulbs, in a kit with soil or peat moss, or already potted and growing, ready to bloom. Some bulbs are sold dipped in wax so they don't need soil ...
Vacuum formed plastic trays and packs were now available and made bedding plant production more versatile. Some growers used soil-based potting soil (1 part sterilized field soil:1 part peat moss:1 part perlite) but progressive growers were using the Cornell peat-lite mix (1 part peat moss:1 part vermiculite).

Peat pots that are biodegradable and may be planted directly into the soil In the nursery business, plants are generally grown in round or square plastic pots. Some organisations (such as the Royal Horticultural Society ) encourage the reuse of (plastic) plant pots and trays across their retail centres. [ 8 ]
When Phythium sphagnum is sprinkled on the soil of germinating seeds, it inhibits growth of "damping off fungus" which would otherwise kill young seedlings. [50] Moss peat is made from Sphagnum. Commercial. Peat is a fuel produced from dried bryophytes, typically Sphagnum.
