1. Select a weed-free site of low fertility
Fertiliser should not be used, since broad-leaved and grass weeds, together with cultivated grasses contained in standard mixtures, can be highly competitive on fertile soils. This can adversely affect seed germination, establishment and subsequent growth. However, increased grass cutting can help to counteract over-competitive growth.
2. Control weeds before sowing
Annual weeds may be hoed, buried or killed with a contact herbicide. Perennial weeds should be eradicated by a translocated glyphosate-based herbicide. Sow mixtures either from early March to early May, or from early August to mid-September. This will ensure the optimum establishment of most species.
3. Cultivate the ground to provide a fine, weed-free seedbed
Firm if necessary. Take care to sow evenly, at the recommended rate. Thoroughly mixing one part seed with four parts dry sand makes it more easily distributed. Rake the seed in lightly with a spring-tined rake and firm the soil by treading or, preferably, rolling. This ensures that the seed comes into contact with moisture in the soil.
4. Water with a fine spray
This will avoid disturbing the surface of the soil. Keep the area well-watered and free from any unwanted plants.
5. Cut the sward every six to eight weeks during the first year after sowing and remove the cuttings
This will prevent the grass from overgrowing the slower-growing wildflowers.
6. In the following years, cut in early spring
Before growth starts, and in October, after all, wildflower seeds have been shed. Remove the cuttings.
Mixture Composition
We have carefully formulated our wildflower mixtures to meet a number of different habitats and soil types. This can range from sandy soil to a hedgerow habitat. Low maintenance grass species (see panel below) are included in the mixtures to act as a nurse crop in the early years of establishment and growth. The grasses help suppress weed invasion, whilst allowing the wildflowers to flourish.

Creating the perfect habitat is vitally important and will enable future generations to know that we played our part in securing our wildlife and plant populations.
The start of this process begins by investing in the right seeds mixture that will allow you to deliver environmental benefits to the highest level.
