I’ve been slowly adding trees to certain parts of the layout recently. These are made using the “Super Trees” product from Scenic Express. The branches are sprayed with 3M super adhesive, then coated with fine green turf from Woodland Scenics. They are then sprayed with cheap hair spray and sprinkled with “Super Leaves” from Scenic Express, then are sealed one more time with hair spray. To plant these, a small hole is either drilled into the plywood or punched into the foam, then foam tack glue applied to the bottom of the trunks, then planted.
Below are photos of the recent work:
