I don't know anything about gardening but I have a small patch of gravel out front where I like to keep some potted plants. My acer's leaves came back healthy after winter but as you can see it isn't doing too good now. I thought the crispy leaves might be because I let it dry out (I was ill for a couple weeks when we had some dry, sunny weather), but looking at the base I noticed this white stuff: https://i.imgur.com/2qc87P3.jpeg, not sure if it's scale or something else? Any ideas what I can do? I see a fair number of tiny bugs and ants in the soil but I'm not sure what's normal. I'm located in the UK, if that matters.

 

I've seen a lot of comments suggesting Threads should be pre-emptively defederated by Lemmy/kbin instances if it tries to join us. I'm a bit confused what the problem would be. When Meta does its usual corporate bullshit over at Threads, how would that hurt a user or community based on Lemmy.world? If anything, wouldn't it give the fediverse a boost if Threads users start discovering communities outside of Meta's control?

I presume I'm missing something, as you can probably tell I don't fully understand how Lemmy, Threads or federation all work.
