How to fertilize Three-Seeded-Mercury

Most potting soils come with ample nutrients which plants use to produce new growth.
By the time your plant has depleted the nutrients in its soil it’s likely grown enough to need a larger pot anyway.
To replenish this plant's nutrients, repot your Three-Seeded-Mercury after it doubles in size or once a year—whichever comes first.

My partner fell in love with this charming pot at one of our local greenhouses today, and it fits my #CopperLeaf perfectly! #HappyPlants #PlantsMakePeopleHappy #PlantTherapy #PotAesthetic #PotHeads

What can I do to save her? My firetails chenille is super dry and her leaves are starting to shrivel up. She was on my to water list for few extra days because I didn't have a lot of time/energy for plant care this week, but I gave her a good soak and mist this morning. I got it from my friend's grandma a few weeks ago, and she said she had the same problem last year when she brought this kind of plants inside at the end of the summer. Is this happening because I didn't water her on time, or just because they do this? #HappyPlants #plantsmakepeoplehappy #Firetails

Any tips on propagation of Copperleaf plants by cutting (water/soil) etc., I think they're so beautiful and the other varieties with green and pink leaves which I believe are in the same category of plant, thanks #propogation #tips ? #Copperleaf

Are these the start of catechins? My chenille plant was at death's door around the end of June. So much so that I started a gallon sized Ziploc of cuttings as insurance. Anyway, it's doing a lot better now, but I'd like it to be more compact and bushy, like the original plant. Any hints for that? Also, it has the little fuzzy areas near a few leaf joints. I'm not certain if they are air roots, or if they are the beginnings of catechins, since they are pink/red fuzz.

🪴 Soil
