Part 2 in our not-so-mini series looking at trees in bioretention. Today, a viewer question.

Peter asks "I like you're approach to trees in bioretention systems. Is there purpose really to shade out weeds though? Wouldn't we need to change the understorey planting once the trees are established and the light regime changes for the smaller plant?"

Very good question. Let's take a look!

In case you missed it, here is Part 1 in the series - Why we're obsessed with trees in bioretention.

Cheers
