I've just got an Asus laptop with Windows 10, nothing special. I'll give stashing the plants a shot, I haven't tried that yet!

Edit: That worked for a few minutes, but immediately after buying a third plant the issue arose again, and stashing the plants won't fix it this time

I just downloaded the game and I've enjoyed what little I've been able to play of it, but no matter where I try to place my second garden plant, there isn't enough light. I tried moving my first one to give its space to the second but that didn't work, and now my first one won't grow either. Any idea how I could fix this?
