Full control often requires a well timed herbicide treatment, but this time of year with it producing all these seeds, even just clipping it and throwing it away can slow the spread. It’s all over the place in DC and elsewhere in the mid Atlantic, so go check!

Found these Boletes in the grass about 70 feet from this red oak. These mushrooms are connected to its root system. Pretty neat how far the roots go! This species stains blue when you scratch it, hence the smiley face. Believe these are red mouth boletes, which are poisonous. Not harmful to the tree, and often beneficial.

What a roller coaster. Invasive plants, some major shade thrown at cinder blocks, and feeding wildlife. Is this format helpful? People seem to like these so far. Easy for me, I just go for a walk and turn the camera on when I see something I feel like talking about. For advice on managing invasive plants, I recommend consulting your local extension website to find a solution that works for you. Chemical treatment is sometimes the most effective option, and you need to carefully time any treatment to maximize effectiveness and minimize how much chemical is needed.

Cheap and fast isn’t necessarily cheap and fast when it comes to clearing overgrown areas in your yard. Listen to see what I mean and see a specific example I see a lot. Most of the time you are better served identifying the plants that are CAUSING the overgrown look, considering the most effective approach to control those specific plants first, and only then do you get your tools out. When you start cutting or spraying or digging first, you often waste time (or money, if you’ve hired help), and you might be harming existing plants that would actually help you manage the space better. Comment if this was helpful or if anything is unclear!

Appreciation post for a few native trouble makers I see in the neighborhood. Plants that say “oh you’re not using this space? Be a shame if someone snuck in here and… supported local wildlife.”
First two pictures are Catalpas, one in a semi abandoned back yard and the other a young one popping up against a sidewalk. Then a redbud that popped up way too close to someone’s house. And finally some pokeweed and horseweed in an alley. Those two honestly aren’t going to hurt anything but eventually someone will probably find them to be messy and remove them. In the meantime, many thousands of native insects and birds will enjoy all these rebellious plants and depend on them for food and shelter.

Found a couple of these neat bolete mushrooms in a wooded area. I’m not a mycologist so can’t confirm the exact species of bolete, but I can tell you that they are a mycorrhizal fungus that forms a mutually beneficial relationship with the root systems of nearby native trees! Healthy ecosystems with a diverse mix of native trees and other plants are more able to support mushrooms like this, so it makes me happy to see these little guys here. Also, some kinds of boletes change color when you scratch them!

For those of you who remember my video about May apples, here’s a follow up! I took a walk through the same area and here they are with fruit on them. They fade as the weather gets hotter and goes dormant. They seem to stay up longer the more shade they get. And they’re right next to everyone’s favorite native plant, poison ivy. And a couple other not so native things.

Spotted lanternfly nymphs are out and about! They’re like 5x this size at maturity and way nastier. Squish em while they’re still small. Not only is this fun and helps (BARELY) reduce their numbers, it has another little known benefit.

Pull it! Or cut it. Or twist it. Or bop it. Whatever you gotta do.
