Adding Foliage

Hey guys

I am working on my fourth model of the new year, a Tamiya Stug III G. I am wanting to paint and mark it as a vehicle used in Normandy. I have the markings I (i think) but while doing some research I came across a very interesting photo og a Stug III covered in foliage. Whats the best technique for adding foliage to a 1/35 scale model?

I used some proper size foilage from model railroad supplies,they have all diffrent sizes and colors
