Clay Soil can be a problem to some native fauna as excessive moisture can be detrimental to healthy and sustained root growth in the winter whilst clay soil can dry like concrete in the summer. This can be true of both wildflowers and grasses. The species in our clay soil mix are known to freely inhabit these conditions and are very suited to the character of clay, or clay based soils.
This Wildflower Meadow for Clay Soil mixture does also does extremely well around ponds, aside a water course (such as a steam or river bank) and on most slow to drain areas providing the soil temperature is reasonably good. In our experience it is best to avoid late and early season sowings, particularly on heavier, wetter soils.
On smaller areas it can be of great benefit to work some grit into the seedbed before sowing as this can significantly reduce the risk of seedlings damping off during early establishment.

All broadleaf and grass weeds should be controlled by hoeing or with a general herbicide before sowing takes place. Low soil fertility should be maintained at all times.
For the best results, evenly broadcast the entire seeds mixture over a fine, clean seedbed which already has a little loose soil on the surface. Lightly rake them into the loose soil before rolling, treading or tamping the surface firm again to place the wildflower meadow seeds into intimate contact with the seedbed.
Perennial wildflower meadows often take over 12 months to fully establish so we include a little native annual wildflower seed in our mixtures for additional first year colour.

Never apply fertiliser or any type of selective, broadleaf weed control to an area sown with wildflower meadow for clay soil.
