Peat-Free Troubles Today? Sounds Familiar, Doesn't It? It Seems That's Been the Case All Along!
Criticisms Arise Upon Peat's Initial Introduction
In the early years of peat's debut in commercial horticulture, many well-known gardeners and experts had reservations about the newcomer. Yet, venerable testimony and gardening books of the time acknowledge these reasons for their distrust:
Nutrient Paucity: Peat itself is naturally devoid of essential nutrients, so early peat-based blends, if not enriched with additional nutrients, could lead to inadequate plant development. Traditionalists were partial to richer options like decomposed manure or loam-based John Innes composts [1].
Watery Quandaries: Once dry, peat may become hydrophobic, rendering it frustrating for gardeners to moisten. This predicament was particularly apparent in warmer weather or greenhouse conditions [1].
Industrious Inconsistency: Commercial peat extraction during those days was inconsistent, resulting in contamination with debris, sticks, or even sand in some shipments. Seems there's no shortage of that, alas [1].
Today, we hear the same grumblings about peat-free composts. Sound familiar?
Scepticism from Skilled Gardeners:
Greenhouse and Nursery Obstacles: Some commercial growers found that pure peat mixes would compact over time, restricting root growth. Others observed that seedlings in peat-based composts needed more frequent feedings than those in traditional loam-based mixtures [1].
pH Predicaments: Peat is naturally acidic, and without proper lime balancing, it could negatively impact alkaline-preferring plants. Some growers had to alter their practices to accommodate this [1].
Early Scientific Controversy:
Research in the 1940s and 1950s pointed out both the benefits and flaws of peat. Its low cation exchange capacity (CEC), meaning it couldn't hold nutrients as efficiently as mineral soils, was noted as a drawback [2]. Traditionalists were convinced that loam-based composts like John Innes formulas were more reliable for long-term plant health, with peat being better for short-term seedling growth [2].
Resistance to Cultural Changes
Some more conventional gardeners regarded peat as a "lazy" alternative for proper soil management. They insisted that relying on it would foster poorer gardening abilities. You might say the same thing about the "no-dig" approach today. It seems there's always one group of energetic gardeners accusing others of being lazy, though the specifics of laziness change [3].
Regional Ties: In various areas, gardeners in regions with naturally good soil saw less need for peat, while those in urban or poor-soil areas were more inclined to use it [3].
Reflections on Early Complaints about Peat:
Though peat was generally embraced for its convenience and sterility, early criticisms set the stage for later discussions. It wasn't until the 1980s and 1990s that the major backlash arose due to environmental concerns about peat bog destruction, sustainability, and carbon emissions [1].
It's relatively simple to grow seedlings and plants without peat, in my opinion. Many commercial growers opt for peat-free methods, as do the National Trust and other large-scale growers [3]. Peat-free composts necessitate different handling techniques than their peat-based counterparts, but that's not an insurmountable challenge for a skillful gardener [3].
To be honest, I prefer peat-free options because of the environmental harm associated with peat use. It won't be long until governments internationally impose bans on peat, so learning how to navigate peat-free composts in advance makes perfect sense to me [1].
I've called for an international standard for peat-free composts and a shared wisdom on their efficient usage [3].

In the midst of the ongoing debate about the effectiveness of peat-free composts, some seasoned gardeners find similarities with the initial concerns expressed about peat in home-and-garden and gardening literature. These concerns, such as nutrient deficiencies, water retention issues, and inconsistencies in commercial peat sourcing, echo the scepticism gardeners had towards peat in its earlier days.
In light of the growing movement towards sustainable living, many gardeners are turning to peat-free alternatives for their lifestyles, motivated by concerns about environmental impact and carbon emissions, just as there was a backlash against peat in the 1980s and 1990s.
