struggling with plant care advice?

so i've been trying to keep my houseplants alive and thriving, but it seems like i'm always either overwatering or underwatering them. anyone else have this problem? one thing i learned recently is about the finger test—stick your finger about an inch into the soil and if it feels dry, it’s time to water. sounds simple enough, right? yet, somehow i still manage to mess it up! also, i read somewhere that using a moisture meter can help, but i'm hesitant to get one. has anyone tried it? does it actually make a difference? would love to hear any tricks or tips you guys have to keep plants happy. maybe you have a go-to routine or some plant care hacks? 🌿
