weeds

Progress shots of this little bittersweet nightshade From April 2021 till July 2021 I found it behind the vegetable garden and had no idea what it was but put it over a rock and waited for the leaves to show. It is fun watching it develop. It is very fast growing and easy to cultivate species...

Hopefully I’m posting in the correct place. Hoping someone can help. I have a small plant growing from my bonsai tree. Not sure if this is a weed, I’ve added a picture, any advice would be great, thanks.

I found these little weeds growing in the pot around my Shindeshojo and was wondering what the best course of action was.
