The calcareous grassland wildflower mix is characterised by plants which are naturally found growing on shallow, soils with a high pH. The species in the mix are particularly suited to the dry conditions which are created by the free-draining nature of these soil types. The mix is designed to mimic the ‘CG’ National Vegetation Classification categories; the most widely distributed of which are CG2 and CG3.
Calcareous grasslands, such as CG2 and CG3, can provide both feeding and breeding habitats for birds and insects, particularly when managed as part of a mosaic of habitat types.
*Please Note: The contents of our wildflower mixtures will vary according to seed and species availability.

Where to use
Sow the calcareous grassland wildflower mix onto soils which are low in nutrients and have a high pH. Typical soils types are calcareous, chalky and limestone.

When to use
In general, the best time for sowing perennial wildflower seeds is late summer/autumn (late August-October) when there is likely to be consistent moisture and warmth without extremes of cold or dry. Spring (late March-May) is usually considered the next best time to sow perennial wildflower seed, particularly if the ground is likely to be waterlogged over the winter.
How to use
|Prepare the ground|
|New Seed Bed||Overseeding|
|Remove unwanted vegetation
Cultivate the soil to a depth of 150 mm removing the stones and debris
Level, then firm the seedbed
Rake the surface to product a fine tilth
|Cut the grass short as possible and remove the clippings
Remove excess thatch to allow the seed to reach the soil surface
If compacted, aerate the soil
|If there has been little rainfall irrigate gently and slowly to fully wet through the soil profile|
|Sow seeds evenly using the correct sowing rate for the seed mix
Because sowing rates for wildflower seed are low, it is usually helpful to mix the seed with a carrier material such as slightly damp sand
Press the seeds into the soil using a roller or the back of a rake to ensure good seed to soil contact
|Keep the soil surface moist but not wet until the seeds have germinated AND established
Irrigate slowly and gently to avoid disturbing the seeds
Management & aftercare
Grazing with livestock is an effective method of managing wildflower meadows and grasslands because it creates uneven growth and distribution of species which leads to habitat niches. Grazing is also a good option in areas where it is difficult to utilise machinery, perhaps because it is too wet or because the ground is too rough.
|Suggested grazing regime|
|Graze if ground conditions allow||Remove livestock to allow the plants to flower||Graze with between 0.4-1 LU/ha|
Mowing and removing the clippings can be used to replicate the process of hay cutting and grazing. It is important to remove clippings to avoid nutrients being returned to the soil. Soils for wildflowers are usually low in nutrients to encourage species diversity.
|Suggested mowing regime|
|Leave uncut unless growth is vigorous||Cut and collect clippings||Allow to flower and seed||Cut and collect clippings||Leave uncut unless growth is vigorous|
