Hi I live in Massachusetts.In my back yard there is a mature Lilac bush, 8ft tall appox.Every year around the base I get these weed type things,with a bamboo like shoot out of the ground around it?Should I chop all of these out?
They keep coming back every year at the base of the bush.They have large green leaves on them.Thanks

 

Are they new growth for the bush or something different?

Have any pictures?

 

Lilacs can send out new shoots. I'm assuming the leaves aren't the same as those on your lilac bush? A photo would really help as if the shoots aren't lilacs, they could be anything.
