If you have a lawn, and would like it to help #bees, there are a few things you can do less. Don't use pesticides. Don't use herbicides. Don't mow for the first few weeks when the grass begins to grow. This will allow wildflowers such as clover, violets, and self-heal to feed #pollinators. In England, and many parts of the US, this time is May. So this practice is commonly known as #NoMowMay.
