Growth Clay (1000 litres)

Growth clay 1000 litres (1 m³) in a bulk bag

Get your garden's drainage and structure under control with 1000 litres of growth clay in a bulk bag. This size is our absolute bestseller for both private garden owners and landscape gardeners working on a medium-sized garden or renovation project. Growth clay gives your plants free access to oxygen and water by preventing the soil from clumping together and becoming heavy.

With 1 m³ of growth clay, you get enough material to lay solid drainage layers under new paving, mix into heavy clay soils to soften them, or fill several large pots and raised beds. The material is 100% natural, environmentally friendly and never breaks down, making it a one-off investment in the health of your garden.

• Perfect for: Larger raised bed projects, soil improvement in the garden, greenhouses and drainage layers

• Volume: 1000 litres / 1.0 m³

• Properties: Provides oxygen to the roots, prevents standing water and permanently improves soil quality

How much growth clay should I mix into the soil?

The amount of growth clay you should mix into the soil depends on your specific project and your plants' need for drainage and oxygen:

• Ordinary garden beds and raised beds (10–20% growth clay): For standard soil improvement in the garden, a mix with 10 to 20% growth clay is ideal. It loosens heavy, compacted clay soil, improves air circulation around the roots and helps sandy soil retain moisture.

• Pots, balcony boxes and planters (20–30% growth clay): In closed containers, the soil compacts more easily over time. A mix of 20 to 30% growth clay maintains a light and airy soil structure for several seasons.

• Mediterranean plants, cacti and olive trees (30–50% growth clay): Plants that require extremely well-drained soil and are sensitive to standing water thrive best with up to 50% growth clay in the soil mix.

Practical rule of thumb:

If you are mixing a 100-litre batch of ready-to-use soil mix for your pots or raised beds, use 15–20 litres of growth clay and 80–85 litres of topsoil.

Tip: Remember that growth clay mixed into the soil improves its structure, but it does not replace a proper drainage layer. We always recommend placing a clean 3–5 cm layer of growth clay at the bottom of the pot or raised bed before adding the soil mix.

Flexible and easy delivery of growth clay – tailored to your needs

At Maxibag, we place great emphasis on you receiving your growth clay in the most practical way. We have built a flexible logistics system where you choose the solution that best suits your property and your project.

The placement of your bulk bag is crucial. Both to reduce the distance to the pots, beds or construction work, and so that the bag is not in the way if you are planning to use the contents over several rounds. Growth clay is a durable natural material that neither gets damaged nor loses its properties by standing outdoors in the bulk bag. You can therefore safely store any surplus growth clay in the bag and use it throughout the entire gardening season.

Growth clay is delivered in the following quantities:

• 500 litres (0.5 m³)

• 1000 litres (1.0 m³)

• 2000 litres (2.0 m³)

Choose the delivery method that suits you best

Delivery to pavement or driveway

Your bulk bag is set down at the kerb, on the pavement or a little way into the driveway. Simply state your wishes in the comments field when ordering – the driver will then place the goods exactly as requested, without you needing to be at home.

Delivery by mobile forklift

One of our most popular solutions. The driver brings a special forklift with large pneumatic tyres that easily manoeuvres on challenging surfaces such as gravel, stones, crushed stone and soft roads. Ideal for allotment gardens, holiday home areas with narrow paths or long private gravel roads.

Delivery by crane

The ideal choice if your bulk bag needs to be lifted directly over a hedge, a fence or a wall. The lorry's crane places the growth clay precisely where you need it.
