MD residents, thinking about planting a tree this year (or torturing it in a pot as bonsai)? The state gov offers a$25 off on purchase of $50+ for select mostly native tree species from participating nurseries. This is a gov rebate per tree you need to fill out coupon for each qualifying tree purchase. This is an annual program.
