I still need to buy some upgrades, so I want to sell some of my plants from my Zen Garden when they are fully grown.

But how do I know when they are fully grown?

    I'm ambivalent as to whether it's ok to copy questions like that (even linking them)... shouldn't we wait for them to be asked organically? Or are you really interested in an answer?

Each "day" period they should require fewer things to become happy, and fully grown happy plants have a sort of glowing aura that's visible.

  • I think feeding the plant fertilizer 3 times means they are fully grown.

a fully grown plant is one that you can sell for 7500 for most plants, 10000 for nighttime and pooltime plants and 3k for daisies

you know you can sell a plant if when you fertilize it it give diamond(s), if it wants bug spray or if it wants to listen to music
