As we continue the wrap-up of #BLTrees with Marielle Anzelone, urban botanist and ecologist and the founder of NYC Wildflower Week, we are joined by Amy Pearl, audio and video producer at WNYC, to talk about memorial trees.

→For Friday's show, get creative about your tree and write a haiku* in honor of your tree -- or from the point of view of your tree -- or about the web of life that trees are part of. Tweet your October tree pictures and your haikus to #BLTrees or email them to [email protected] with the subject line BLTrees Haiku. We'll read some on the air on Friday. (*three lines of 5, 7, and 5 syllables, if you're following tradition)

Here it is in late October and my local pear tree is still all green. How about your tree? Listen to our final #BLTrees segments today and tomorrow and post your tree photo here. Your tree haikus too! BL pic.twitter.com/5zDCzyGvCI
