I’m not up to running around doing guerrilla gardening myself.

But how cool would it be to seed bomb abandoned lots with native wildflowers for native pollinators? ~~(Not only bees - though they’re important).~~

You can make seed bombs as clay-soil balls, soil bound with flour, dried paper pulp, or soil filled eggshells.

Legality is dubious so check beforehand if you want to do it. And don’t use anything poisonous or invasive.

Edit: Scratch that. This video is saying not to use regular wildflower mixes as some species may be invasive. The natives may be a much better choice until I look at what’s in the bee/butterfly mix
