Hello! The biggest piece of advice I have is to forget about them until they have roots. It feels wrong and it might be as much as a month. Maybe more. But let them grow roots on a dry medium of some sort before you plant them.
One more reddit refugee here. Thanks for all your work so far and your devotion to the project. Growing pains are normal, especially when you're asked to ramp up this fast. Keep up the good work. We'll be patient!
Love your username. I just finished the almost the whole Sanderson library! Everything in the Cosmere, skyward and a few others. It was a long year hahah.
Oh, and the moldy (Hello from across the pond!) succulents are a common problem. Let them dry out ALL. THE. WAY. between waterings. The soil should be crumbly. If the leaves just barely start to wrinkle, that's alright as long as you get to them soon thereafter. You can seriously let them go weeks between waterings sometimes. Check out some of my other posts for some of my succulents that are doing well.
Well, a little good news! While I'm no expert, I have at least some of everything you posted and they're all pretty healthy. I might actually be able to help.
I do mean drains at the bottom of the pot, but also that the soil itself lets water through it. Think of sponges that hold different amounts of water when you squeeze them. Your cactus wants sandy soil so it won't hold much water. Your ivy is less picky but probably wants a peatier soil to keep some moisture around the roots.
Let me know species you have and I'll try to keep helping. Bonsai trees are tricky assholes and I have a love-hate relationship with mine.
I think it'll take a little while but we'll find our niches. I'm finding a few magazines on kbin.social to be really active in and I also got on mastodon.social. I don't think the latter is for me. I need to figure out a little better how federation works then I'm gonna explore more.
Itโs about ten feet with a loop on one end and the frill on the other. Itโs just some PCord she stole from me when I visited years ago. Had it to tie some stuff up and found out quickly it wasnโt mine anymore ๐
