This may be a really stupid question. New to Plant Tycoon. I did a search and found nothing on this subject. One of my plants has a status of "depleted", although it still looks healthy. Anyone know what this means? I'm still very early in the game, just got it today.

It's when the plant has run out of seeds it can produce.

Thanks, I kind of thought it was something like that. It can still pollinate other plants though, correct?

Yes, a plant will always have pollen to pollinate other plants.

but IT cant be pollinated again.

There's reference to that somewhere here, the plant won't die (assuming you keep it watered and it's not in low grade soil, if higher than tier 1 seed).

When a plant shows as "depleted" I know it's time to click the "Sell" button.

I sometimes keep the depleted plants. They can still pollinate other plants even if they can't generate seeds themselves.

i do that too
