Reliable Gardening Services in Woolwich

Not everything on this side of the river sits on clay. The higher ground running south of the town is underlain by sands and pebble beds, and gardens on it behave in the opposite way to the heavy plots a mile or two north. Ground here can be dug in almost any weather, warms early in spring and drains freely after the heaviest rain, and then dries to dust by the end of June and burns off a lawn before most gardens have begun to look tired. Hungry, thirsty soil is the defining condition of SE18.

Recognising the ground for what it is

A handful of it will not roll into a shape, it feels gritty rather than smooth, and water poured into a test hole disappears within minutes. Beds show the other symptoms: plants wilting by early afternoon and recovering overnight, pale foliage on shrubs that ought to be dark, and a surface that goes from damp to dusty within two days of rain. Nutrients leach through it rapidly, which is why a garden that was fed in March looks starved by August.

Organic matter mixed through rather than laid on

On clay, compost is spread on the surface and left for worms to incorporate. On free-draining ground it is worked into the top spit, because the object is to build water-holding capacity within the root zone rather than to open up a dense structure. Well-rotted manure, garden compost, leaf mould and composted bark all help; sharp sand and grit do not, and adding them to ground that is already sandy makes matters slightly worse.

Mulch is the main defence, and it needs depth

A thin scatter of bark achieves nothing on this soil. A layer of seventy-five to a hundred millimetres, laid over ground that is already wet, cuts evaporation substantially and keeps the surface roots cool through a July that would otherwise scorch them. It is topped up annually because it breaks down faster in warm, aerated conditions than it would on a cold clay bed. Gravel mulch does the same job around drought-tolerant planting and lasts far longer.

Planting that prefers these conditions

The list that struggles on clay is exactly the list that thrives here. Lavender, rosemary, cistus, ceanothus, phlomis, euphorbia, verbascum, alliums and most of the bulbs want sharp drainage and resent winter wet, and they will outlive anything moisture-loving planted alongside them. Deep-rooted shrubs and trees find water well below the surface once established, so the effort goes into their first two summers. Bedding and thirsty perennials are the wrong choice here, however well they are watered.

Lawns are the first thing to go brown

Grass on sand browns off weeks before it does elsewhere, and the instinct to water it daily wastes a great deal for very little. A lawn allowed to go dormant recovers when the rain returns, whereas one kept shallowly wet all summer develops shallow roots and suffers more the following year. Raising the cutting height, leaving clippings on during dry weather and feeding in spring and autumn rather than at midsummer make far more difference than irrigation does.

Feeding little and often

Soluble nutrients wash straight down through open soil, so a single heavy spring feed is largely wasted by midsummer. Slow-release and organic feeds that break down gradually suit these conditions much better, supplemented during the growing season for anything in a container or being cropped. Soil tests are worth doing here rather than guessing, since free-draining ground often reads more acidic than the clay nearby and a lime-hating shrub may do better than expected.

What a maintenance visit covers

Regular upkeep is charged by the length of the visit and the number of technicians, with the emphasis shifting through the year from cutting and edging in spring to mulching, watering checks and border work in high summer. Bulk mulch and compost deliveries are handled separately, and spoil or old surfacing removed during improvement work leaves by vehicle as with our nearby specialists. Neighbouring gardens on the same beds are covered by trusted lawn mowing in Plumstead, dust-filmed paving by our specialists in the area, burrowing under decking by fully insured wasp nest removal in Woolwich, and the annual pattern by the service in detail.
