Bonsai in Solo cup pot size. How should I treat her.

Personally I would intensify the light. This will make her short squated and miniature. Decreasing the light will cause her to stretch. Although you could cut and remove unwanted branching. I would place them on a milk crate or something similar, increasing the light thus making her more squat, then use training wire to train her into the shape you desire. If you click on contest. You can look back, several months ago there was a miniature growing competition. Manu grew out of tiny containers, a couple even doing bonsai looking plants like yourself. Hope this helped, it's just my opinion. I've never tried it. Maybe those diaries in the miniature competition have valuable information to help you and your journey. Goodluck! Please consider selecting me as the answer so I can be entered for a chance to win grower of the month contest I would really appreciate your support 😊 🙏
