wild growth discontinued in potted plants

Are you missing the fertilizer or whatever additional components it needs? IMO, a design flaw, but once you have potted a plant, it is considered domesticated and will require additional resources for it to grow at all (mealwood aside) . The plant will not progress even when presented with its natural wild growth requirements.

This is as designed; the plant has been disturbed from its natural state and requires Duplicant nurturing to continue growing. We will look into improving the descriptions so that this is more clear. Thanks for reporting it!
