Repotted all 3 together into bigger pot. I hope general purpose mix will suit them. (And this batat is growing too fast for these containers, will put them somewhere else). That was it for #repotting-day and still have many plans to repot due to impulse purchase. Oh well.
@sushiwaitress thank you, they are decorative batat you noticed on another photo when they were still small. But it is growing too fast for these containers. I may repot them in hanging basket. I find dark leaved plants something special 💜
