& Poplar)
Most of our region contains limestone-derived soils which are alkaline, as well as many pests and pathogens enjoying a long growing season for them to thrive and multiply. 

As a consequence, we do not recommend the following plants and suggest you avoid them if you desire a carefree and durable landscape.

This area contains way too many shallow-rooted, weak-wooded, borer-bait trees. Please do not add more of them!

The Silvicide Song, "Cut Down the Trash Trees", below right, is sung to the tune of "Hava Nagila", which means, "let us rejoice" (turn up the audio to hear it). 

Cut Down the Trash Trees

Cut down the trash trees,
Kill all the trash trees,
Cut down the trash trees,
Fi - nish them off!

Cut down the trash trees,
Kill all the trash trees,
Cut down the trash trees,
Fi - nish them off!

Cut them below the ground,
Two inches lower, still,
Grind out the stumps as well,
Fi - nish them off!

Cut them below the ground,
Two inches lower, still,
Grind out the stumps as well,
Fi - nish them off!

Oh - look - one - is - fall - ing, 
Crashing down and shattering loudly,
Crashing down and shattering loudly, 
Splintering and disintegrating,
Useless even for the wood stove, 
Crashing down,
Crashing down,
One less trash tree in our town!
