Choosing the right flowering seed mix

Although a range of flowering plant seeds may be included in all flowering seed mixes, selecting a mix at random won’t necessarily give you the results you want for your crops.

Back to Using flowering seed mixes to improve farmland biodiversity

There are many options available but selecting a general seed mix at random is not always cost-effective.

There are several reasons for this:

  1. ‘Generalist’ seed mixes do not necessarily contain plant species suited to agricultural settings.
  2. ‘Generalist’ seed mixes often contain seeds of flowering plant species that may be used by pests of certain Small plot studies have shown that inclusion of such flowers can increase the number of pests in your crops.
  3. Most nectar and pollen mixes have been designed specifically with bees and butterflies in mind. That means they don’t necessarily cater for pest natural enemies, such as parasitoid wasps and hoverflies. Similarly, seed mixes designed for pest enemies are not always beneficial for pollinators.

It’s essential to choose your seed mix carefully to encourage multiple insect groups without attracting too many pest insects.
