How to Make Gem Trees Grow Faster in Terraria
Gem trees in Terraria are a bit picky, but there's no real 'speed up' button. They need to be planted on gemspark blocks which match the type of gemcorn you're planting. Also, patience is key! These trees take their sweet time, and there's no fertilizer or growth potion to speed them up. Just make sure they have enough space (about 3 tiles in width) and are planted in underground or cavern layers. Good lighting doesn't hurt either!

Honestly, just wait. Gem trees grow at their own pace. No shortcuts here.
First-hand experience here: make sure you're planting those gemcorns in the right environment! Had mine in the wrong layer and they just wouldn't grow. Once I moved them to the underground layer on the matching gemspark blocks, they started growing. It's all about that patience and making sure you've got the conditions right.
