Still a popular cover crop in the south of the UK, sorghum provides a warm and windproof cover crop. Often grown alongside maize as a wind break, sorghum has also come into its own as part of many wild bird seed mixes as it stands so well and helps hold up some of the weaker seed bearing species. It must not be sown until the soil temperature reaches 14°C.
A very popular food crop in the warmer parts of the UK, millet forms the basis of many wild bird seed mixes as well as being a useful early food source for game birds. Red and white millet are primarily ‘food’ producing species whilst Japanese reed millet is an excellent winter cover crop in its own right.
