Dark, spongy and light in the hand, holding a great deal of water and distinctly acid. Uncommon in gardens outside particular districts, and unmistakable where it occurs.
Not sure this is you? Four hand tests will settle it — the squeeze test alone distinguishes the main textures in about a minute.

Applies when: Undrained peat is waterlogged by definition, since that is how it formed. Drained garden peat behaves quite differently and shrinks as it oxidises.

Every soil grows something better than loam does, and a description that lists only problems is a complaint rather than intelligence.

The thing most worth knowing
Where peaty ground exists, the environmentally responsible course is usually to work with it rather than to drain and improve it. Grow the acid-lovers that suit it and raise the rest in beds above it.
Not problems it causes — problems whose severity this soil materially changes. The distinction matters, because the remedy is usually about the soil rather than the pest.
Clubroot is worst on acid, wet soil, which describes this one exactly. Liming before brassicas and raising the plants in modules to get them past the vulnerable stage are the standard responses; neither eradicates it.

Computed across 223 plants by comparing each one's recorded requirements against this soil's recorded characteristics. Every verdict can be taken apart into the criteria that produced it, and a recorded horticultural fact overrides the computation where one exists.

Each of these states its ceiling as well as its effect, because every soil improvement is oversold somewhere and a gardener who knows where it stops does not keep going for another three years.
Raises soil pH gradually, which improves the availability of most nutrients on an acid soil and substantially reduces the severity of clubroot in brassicas. The effect is measured in fractions of a pH point per application.

What it will not do: It is not permanent — rain leaches it out and the soil returns towards its natural pH over a few years, so it is a maintenance practice rather than a fix. It will not make an acid soil alkaline, and it cannot be undone once overdone.
Test before liming rather than after. Over-liming locks up iron and manganese and is far harder to correct than under-liming, and lime should not be applied at the same time as manure or nitrogen fertiliser because the combination releases ammonia and wastes both. Lime is caustic: keep it off skin and eyes.

Lifts the root zone above the water table, so roots are in soil that drains even when the ground beneath does not. It also warms earlier in spring and gives rooting depth where there is rock or hardpan close to the surface.

What it will not do: It does not drain the ground underneath. A raised bed on waterlogged clay is a container sitting on a puddle: it works because the roots are above the problem, not because the problem is gone. Beds under about 20 cm deep achieve very little of this.
Adds organic matter without importing it, protects the surface from winter rain — which is what causes capping and nutrient leaching on light and silty soils — and, with a legume, fixes nitrogen. Deep-rooted types such as grazing rye break into moderately compacted ground.

What it will not do: The quantity of organic matter a green manure adds is small compared with a barrowload of compost — its value is in covering ground through winter and in the roots, not in bulk. It also occupies the bed, which is the real cost on a small plot.
Do not let a green manure set seed, and choose one from a different family to the crop that follows. Mustard is a brassica, so it should never precede or follow brassicas on ground where clubroot is a risk.
