This mixture of UK native wildflower species and selected non-native species, coupled with accompanying grasses that tolerate heavy clay soils, provides floral interest from late April to September and creates a great habitat for invertebrates - which in turn provides food for birds and mammals.

If possible when cutting in late summer an area of up to one third should be left uncut until the following Spring for overwintering invertebrates. This area should be alternated each year.

Due to the nature of clay soils, extra attention is required in terms of seed bed preparation to encourage good establishment. Cultivate when soil moisture allows breakdown of the soil aggregates into a medium tilth. 

An 80:20 mix of grasses and annual & perennial flowers including Betony, Wild Carrot and Ribwort Plantain.

Sowing Rate 5 g/m2
Sowing Time March - October
Sowing Depth 10 mm
Sowing Instructions Create a fine friable seedbed down to 150 mm in depth. Carry out two equal sowings at right angles to each other and diagonally to main axis. Broadcast manually or use seed drill, rake level and roll. Ensure good seed to soil contact.

First cut mid-September - 1st October and collect the arisings.

Cutting height 70 -100 mm.


Cut from mid-August to early October. This can be done as one cut but preferable, and if the meadow is big enough, you will cut it in sections leaving a week to a fortnight between cuts. Ensure you collect the arisings. If the meadow is large enough, consider allowing up to a fifth to stand uncut through the winter and cut down and remove the clippings in March the following year, this will provide a habitat for invertebrates and some vertebrates over the winter. Rotate this area so a different section is left uncut each year. This more closely replicates the grazing of animals which would leave some small areas not grazed.

If possible, and with the obvious exception of areas you are leaving uncut, lightly mow the sward down to 70 -100 mm as required throughout the winter months until March and collect the clippings.
