What it is
An orchard soil has to do two contradictory things: hold enough water to carry a tree through a dry midsummer, and shed enough of it that the roots are never sitting without air. Soil and drainage work is the assessment of texture, depth, structure, organic matter, pH and water table before planting, and the correction of what can be corrected — subsoiling a pan, cutting a drain, ridging a planting line, liming an acid soil — while the ground is still bare. After planting the options narrow sharply, because the tools that fix a drainage problem are the ones that cannot be run through an established root system.
Why it is used
- Saturated soil excludes air from the root zone, and apple roots die in the absence of oxygen well before the tree shows anything above ground.
- Free water in the soil is the medium in which Phytophthora zoospores swim to the collar and root, so wet ground is a disease problem and not only a physical one.
- Soil depth and fertility set the effective vigour of any rootstock, so the same stock behaves as semi-dwarfing on one soil and as a standard on another.
- Soil pH governs which nutrients are chemically available to the roots, and correcting it is far easier before trees are in the ground than afterwards.
How it works
- Roots respire, and respiration needs oxygen; when pores fill with water gas exchange stops, root tissue goes anaerobic and dies, and the tree loses absorbing surface at the point in spring when it needs it most.
- Texture and organic matter set available water capacity — the fraction of soil water a root can actually extract — so a deep silty loam buffers drought that a shallow sand cannot.
- A compaction pan formed by machinery or by cultivating in wet conditions perches water above it and blocks rooting below it, producing a shallow root plate that both waterlogs and droughts.
- At high pH iron and manganese become progressively less available to the tree; at low pH manganese and aluminium become more soluble and phosphorus is locked up, which is why pH correction precedes any fertiliser decision.

More on soil and drainage
The classic cider soils are not one type. The Three Counties orchards sit largely on heavy clay loams over marl and Devonian mudstone, soils with good reserves of moisture and a real risk of winter waterlogging and structural damage from traffic. Somerset has both the heavier ground of the hills and the alluvial silts and peats of the Levels, where the water table is managed at a landscape scale by ditches and pumps rather than by anything a grower does within the orchard. Normandy’s cider country carries heavy loams with a long tradition of hedge-and-ditch boundaries doing much of the drainage work. In Asturias and the Basque country the parent materials and the high rainfall of the Cantabrian coast commonly give acid soils, and liming is a routine part of establishing an orchard there rather than an unusual intervention.
The mechanism that matters most in practice is the interaction between water and root disease. Collar rot and root rot caused by Phytophthora species need free water to move, and the sites that produce them are the ones that hold water at the trunk base — a hollow, a drain outfall, the low end of a row, or a planting hole dug in wet clay that has effectively become a sump. This is why so much orchard drainage practice is about the first few centimetres around the trunk rather than about the field as a whole: planting on a low ridge or a slight mound, keeping mulch and soil away from the collar, and making sure that surface water leaves the row rather than gathering in it.
A grower deciding what to do before planting is choosing between permanent works and permanent compromise. Mole drainage, piped drains and subsoiling can be done cheaply while the field is open and expensively or not at all afterwards. Beyond that, the honest response to a wet site is to change the tree rather than the ground: a more vigorous rootstock with a coarser, more tolerant root system, wider spacing, a raised planting line and a system that does not demand heavy machinery in the rows during a wet autumn. Ignoring the problem produces a familiar pattern — trees that establish acceptably for a few seasons, then thin out, decline from the collar upward, and die unevenly across the wettest part of the block.

Site selection
Choosing the ground an orchard will stand on, weighing frost drainage, exposure, soil depth and season length decades before the first full crop is picked.
Orchard
Orchard nutrition
Deciding what the trees are fed and how much, a balance in which too little nitrogen shows up as a difficult fermentation and too much shows up as canker and soft growth.
Orchard
Rootstock choice
Selecting the root system a cider cultivar is grafted onto, which fixes tree size, how soon it crops, how long it lives and what soil and orchard system it will tolerate.
Orchard
Orchard planting
The establishment operation itself — tree quality, timing, planting depth, support and protection — which decides whether a young orchard grows away in its first two seasons or never catches up.
Orchard
Pest and disease management
Keeping scab, canker, rots and the main insect pests to a level the orchard can carry, at a cosmetic standard well below dessert fruit but without allowing rot into the crop.
What people ask next
Questions readers ask about the things this page mentions. Each one goes to the section that answers it rather than to a page written to receive the question.
- What makes a good site for a cider orchard — Frost drainage first, then soil depth and water. A hollow that traps cold air on a May night can lose a crop at blossom, and no later decision recovers it.
- What rootstock should i use for cider apples — Rootstock sets tree size, how soon it crops and how long it lives. Traditional standard orchards used vigorous or seedling stocks for large, long-lived trees; modern bush orchards use semi-dwarfing stocks that crop early and can be machine-harvested.
