Building Biodiverse Urban Gardens

How big does an urban garden need to be to support pollinators and other important insects? What kinds of plants lead to the most biodiverse space? How should homeowners manage their gardens to support the natural world?

Get the full garden scoop with PhD researcher Joeri Morpurgo, from University Leiden in the Netherlands! Morpurgo and his colleagues visited urban gardens throughout Amsterdam and counted all the different plant and insect species they could find. 

Some key findings? Gardens can be small but mighty--as long as there's dense foliage and a plethora of plant species, they supported a variety of insect species. And one controversial finding: native vs. non-native plant species didn't seem to make a difference to insect diversity. 

Hear Morpurgo's take on his findings, and his urban garden management recommendations on the podcast!
