Caring for your plans is essentially a reminder to care for yourself.

When I struggled mentally and found it hard to take care of myself, my plants suffered because I wasn't caring for them either. However, when they're happy and green, it usually means I'm more attentive to myself and taking care of my physical and emotional needs. When I'm able to witness the way my plants leaves naturally unfertile to receive the sunlight, I get an instant boost of happiness. It reminds me to do what I find fulfilling, instead of solely focusing on my obligations. It's a reminder to always keep going and keep growing.
