Mulch is the most misapplied material in a garden. It goes on too thin to do anything, or onto ground that is bone dry, or in a cone piled against the trunk of a tree that then dies slowly over five years. Applied properly it is the single most useful thing done to a border all year, and in SE27, where heavy ground bakes hard in July and sits wet in February, the difference between a mulched bed and an unmulched one is visible from the back door.

What the layer is actually doing

Four things at once. It slows evaporation, so the soil beneath stays damp for far longer after rain. It buffers temperature, keeping roots cooler in summer and reducing the freeze and thaw that lifts new plants out of the ground. It denies light to weed seed sitting at the surface. And, where the material is organic, worms drag it down over the season and improve the structure of a clay soil more effectively than any amount of digging.

The timing rule that decides everything

A mulch does not add water; it holds whatever is already there. Spread over dry ground it acts as a lid and keeps rain out, so the bed underneath gets drier rather than wetter. The window is late winter to mid-spring, after a wet spell, once the soil has begun to warm but before growth is away. If it has been dry, the ground is soaked first. Autumn application works for protecting tender crowns but does less for the summer that follows.

Depth, and the space around the stem

Below about five centimetres a mulch suppresses nothing, and most disappointment comes from a thin scattering that looked generous in the barrow. Between five and eight centimetres is the working range across a border. The exception is the area immediately around each plant: mulch heaped against a stem or a trunk holds the bark permanently wet, rots it and admits disease, so a clear gap of a hand's width is left around everything woody. A ring of mulch under a tree with bare bark at the centre is the correct shape.

Choosing the material for the job

Well-rotted garden compost and composted bark suit ornamental borders and feed as they break down. Leaf mould is excellent for woodland planting and adds little nutrition, which is often exactly what is wanted. Rotted manure goes on hungry beds rather than around drought-loving plants. Gravel or grit is the right answer over anything that resents winter wet at the collar. Fresh wood chip belongs on paths and around established trees, not dug into a border, because material that has not composted takes nitrogen from the soil surface as it breaks down.

What it will not do

A mulch is not a substitute for weeding. Bindweed, couch and ground elder come straight through it, so perennial roots are cleared before any material goes down, and that debris leaving the site is arranged through Blackheath garden waste collection. Seed blown onto the surface afterwards germinates happily in a loose layer, though it pulls out with a finger. It will not cure compaction, it will not correct drainage, and a deep layer banked against a house wall gives shelter at ground level that makes a run indoors easier, which is a matter for local specialists rather than for the border.

Getting the material in and spread

Quantities surprise people. A modest border at a useful depth takes a cubic metre or more, which arrives as a bulk bag needing somewhere legitimate to stand, and if that is the footway or a parking bay the permit position is confirmed first. Everything is then barrowed through, which on a terraced plot with a side return sets the pace of the whole job. Spillage onto paving is unavoidable and marks it, so cleaning afterwards is usually left to pressure washing cover across Tulse Hill.

How the work is quoted

Mulching is priced on the volume of material and the area covered rather than by the hour, with the carrying distance from the delivery point the main variable. It is normally combined with the late-winter cut-back and weeding, since there is no sense in spreading over uncleared ground, and most gardens want it every year or every other year on the same beds. The same seasonal work in the neighbouring districts is covered by vetted gardening in West Norwood, and the way a round is arranged through the year is explained on professional garden maintenance.
