How to use Rolawn Soil Improver

Rolawn Soil Improver is a versatile product which can be used in a number of ways to add organic matter in the garden; as a soil improver or conditioner, as a mulch and also as a general compost.

As with any type of compost, always wear gloves when using this product and wash your hands after use.

Improving soil structure

Dig over the area in question. Spread a layer of Soil Improver to the desired depth. Work the soil improver into the soil with a fork, incorporating it to a depth of 200mm, taking care not to disturb the subsoil.

If working in a planted area, do not dig too close to the plants or their roots.

When to apply a soil improver

Rolawn Soil Improver can be applied at any time of year, but care must be taken to avoid compaction when the soil is wet, as it may damage the soil structure.

Recommended depths

We recommend applying Soil Improver at the following depths to enrich garden soils with low levels of organic matter:

  • Heavy clay soil - 75mm deep
  • Chalky soil - 50mm deep
  • Light sandy soil - 30mm deep

Mulching beds & borders

Soil Improver also makes an ideal mulch for beds and borders. Earthworms and microorganisms will gradually work it in to the soil below, improving the structure and fertility of the soil in the process. Apply a layer of Soil Improver to the required depth and spread evenly.

Mulching will also help to keep weeds at bay, retain moisture and protect plant roots from fluctuations in temperature. For this type of application we recommend a depth of 50 to 75mm to ensure good coverage and prevent sunlight from reaching weed seeds lying dormant in the soil.

See How to apply mulch or watch our How to apply bark mulch video for further advice. 

As a multi-purpose compost

Rolawn Soil Improver is also suitable for use as a growing media, although we don't recommend using it as a seed sowing compost.

Pricking out

Fill the pot or tray with compost and level off. Gently firm it down and then water well with a fine rose watering can and allow to drain. Dibble (poke) small holes in the compost and then, whilst holding the seedling by a seed leaf, insert the seedling into a hole to just below its seed leaves. Lightly firm around the base of the seedling and water in with a fine rose watering can. 

Cuttings

Fill the pot or tray with compost and level off. Gently firm it down. Prepare the cutting from healthy non-flowering shoots. Insert the cuttings into holes in the compost, firm lightly and water in with a fine rose watering can. To retain moisture, cover with either glass or polythene, until rooted. Ensure that the cover does not touch the cutting. Pot on, when rooted sufficiently and generally when the plant is actively growing, i.e. from spring to early autumn.

Potting on

Water the plant and allow to drain, before removing it from its existing pot. Fill the bottom of the new pot with a layer of compost and place the rootball inside the pot. Gradually fill the pot, gently firming as you progress and level off. Water in carefully. 

Containers

Choose a container that has sufficient drainage holes or where necessary and practicable, create additional holes. Fill the container with compost and then add the plants. Once the planting is complete, firm gently and water in thoroughly. 

Hanging baskets

Place the basket on a surface which will keep it stable e.g. a pot or a bucket is ideal for rounded baskets. Line the basket before filling it with Soil Improver. To help create a ball of colour, where possible, insert plants through the side of the basket and liner as well as arranging plants on the surface. Once the planting is complete, firm gently and water in thoroughly. 

Watering & feeding

Never let the compost dry out completely but avoid over watering. Approximately 4-6 weeks after planting, consider feeding on a regular basis, taking care to follow the instructions on the feed packaging. 

Storage & general advice

It is recommended that compost is replaced annually to ensure the best results.

If any product is left over it should be stored with a polythene cover over it, away from weedkiller and other chemicals, for later use. 

Not suitable for lime-hating plants, such as Azaleas, Rhododendrons, Pieris, Heathers and Camellias.
