Ready-to-use black soap cleans numerous surfaces such as tiles, stones, wood, leaves soiled by aphids and scale insects... It is multi-purpose, and it can be used in the home and garden. Packaged in a 750 ml spray bottle, it is very practical to use.
This ready-to-use spray solution contains less than 5% potassium soap, pine oil and citric acid. It possesses cleaning and degreasing properties used for years, both in the home and on outdoor terraces and paving. Black soap also has antibacterial and insecticidal effects. In the garden, apply it to leaves to eliminate certain undesirable insects: aphids, scale insects, but also mites, red spiders, whiteflies, psyllids and other thrips. It acts by contact, killing the larvae. It also cleans honeydew, a sticky, sugary exudate that promotes the development of sooty mould, that black mould which covers leaves.
Usage advice:
- To clean tiled or paved surfaces: apply the product with a sponge or by spraying onto the areas to be cleaned.
- As an insecticide, preferably use black soap in the morning, when dew is present on the vegetation, or start by lightly showering the plants, before spraying the black soap 1/2 hour later. Avoid treatment during the sunniest hours and periods of intense heat.
It can be beneficial to clean branches and bark during the plant's dormant period, from leaf fall, before the spring bud burst period. This helps eliminate certain insect larvae or spores of pathogenic fungi that overwinter on the bark, waiting for spring's return. Applying 2 to 3 preventive treatments helps limit and delay the appearance of certain pests and diseases. If you use black soap on fruit trees or shrubs or on vegetable crops, wait 5 days before harvesting. If you have treated a vine, the pre-harvest interval extends to 21 days.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).
In temperate climates, pruning of spring-flowering shrubs (forsythia, spireas, etc.) should be done just after flowering.
Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
The sowing periods indicated on our website apply to countries and regions within USDA Zone 8 (France, UK, Ireland, Netherlands).
In colder areas (Scandinavia, Poland, Austria...), delay any outdoor sowing by 3-4 weeks, or sow under glass.
In warmer climes (Italy, Spain, Greece, etc.), bring outdoor sowing forward by a few weeks.
The planting period indicated on our website applies to regions in USDA Zone 9a (East Coast and Midlands: Dublin, Wexford, Waterford, Kilkenny, Portlaoise). It will vary depending on where you live:
- On the west coast and in the north-west (Galway, Limerick, Sligo, Donegal, Westport), delay planting by 1 to 2 weeks in spring and bring it forward by 1 to 2 weeks in autumn compared to the dates given, preferably choosing periods without strong winds.
- In the inland hills and plateaus (Wicklow Mountains, Macgillycuddy’s Reeks, Connemara, Killarney), it is best to plant in spring (April–May) or autumn (September–October), avoiding periods of waterlogged soil in winter and strong winds, which pose the main risk to newly planted trees in these areas.
The flowering period indicated on our website applies to regions in USDA Zone 9a, such as the East Coast and Midlands, including Dublin, Wexford, Waterford, Kilkenny and Portlaoise.
This will vary depending on where you live:
- On the west coast and in the northwest (Galway, Limerick, Sligo, Donegal and Westport), it will be delayed by one to two weeks compared to the given dates, due to stronger Atlantic winds and less spring sunshine.
- In the inland hills and plateaus (the Wicklow Mountains, the Macgillycuddy's Reeks, Connemara and Killarney), flowering will be delayed by two to three weeks. Flowering mainly occurs between May and July, with the limiting factors being less frost and more of the excessive humidity, strong winds and lack of sunshine that are characteristic of these areas.
The harvest period stated on our website applies to regions in USDA zones 8b to 9a (East, South-East and southern coast: Eastern Leinster, County Wexford and County Waterford, Cork region: Dublin, Wexford, Waterford, Kilkenny, Cork). It will vary depending on where you live:
- In the Midlands and the inland plains: the Middle Shannon Valley, Westmeath, Offaly, Longford, Cavan and Monaghan (Athlone, Mullingar, Tullamore, Longford, Cavan, Monaghan), in USDA zones 8a to 8b, the harvest will be delayed by 1 to 2 weeks compared with the dates given. Far from the moderating influence of the sea, these plains experience late frosts right up until the end of spring. The heavy, peaty soils warm slowly here, and damp patches form pockets of frost. Wait until the soil has dried out and warmed up before planting, and protect young plants with a fleece on clear nights.
- In the Atlantic West and North-West: Kerry, Clare, Galway, Connemara, Mayo, Sligo and Donegal (Killarney, Ennis, Galway, Westport, Sligo, Letterkenny), in USDA zones 8b to 10a, the harvest will be delayed by 1 to 3 weeks compared with the dates given. Summers here are cloudier, rainier and windier than in the east, which slows down ripening and encourages late blight and other fungal diseases. Kerry and Clare are at the lower end of the range, whilst Mayo and Donegal, which are cooler and more exposed, are at the upper end. However, the mild coastal winters mean that leafy vegetables and root vegetables can be harvested at dates close to those indicated, or even earlier: shelter crops from the wind with hedges and grow heat-loving plants in greenhouses or polytunnels.
- In the highlands, above 200 m: the Wicklow Mountains, Macgillycuddy’s Reeks, the Galtee and Comeragh ranges, the Twelve Bens in Connemara and the Donegal highlands, in USDA zones 7b to 8a, the harvest will be delayed by 2 to 4 weeks compared with the dates given, depending on the altitude, taking care to beat the first early frosts, which may occur as early as the start of autumn. Wind, constant damp and late frosts lasting into early summer significantly shorten the growing season. Opt for sheltered, south-facing slopes, early-maturing varieties and growing under cover.
Depending on your garden’s aspect, these variations can range from one to two weeks. A frost-prone valley floor delays the harvest, whilst a south-facing wall brings it forward.
