Wildflower Site Preparation

The site should be weed free. Annual weeds should be controlled by mechanical means or by the use of contact based herbicide. Perennial weeds, for example docks thistle, nettles and couch grass can be dealt with using a translocated herbicide such as Round-Up. Cultivate to achieve a fine seed bed, sow seed mix and then roll to ensure firmness. The best results are obtained when there is good contact between the soil and the seeds.

Sowing Times

Sowing can best be achieved by mixing the seed with dry sand, dry sifted topsoil or sawdust and evenly broadcast. It is important that the seed is in contact with moisture in the soil so the seedbed should be lightly raked and then rolled.
