The inspiring guerrilla gardeners over in Brussels are calling for an international day of stealth planting of sunflower seeds in every abandoned parcel of land on May 1st. Their blog has a complete instructional on the planting and care of the seeds and also has a great inspirational photo set of people’s successful plantings last year. Here are some of the pictures to get you going! I’ll definitely be out there, just got my seeds yesterday. Check out their work here.
