r/gardening’s public description frames a broad plant-and-care community—guides, pictures and discussion across plants in general—while r/houseplants narrows that interest to plants kept indoors. In our directory, gardening is the larger community (about 9.0M members, directory rank #85) against houseplants (about 3.0M, directory rank #357).
Where we have posting samples, gardening mixes images, galleries and text, which matches a community that shares plots, harvests and plant IDs as often as it debates technique. We do not yet have a collected activity sample or short rule titles for houseplants on SubMouse, so those fields stay n/a rather than guessed.
Our directory lists houseplants among related communities for gardening. That is a direct link between these two names—not a claim that every other name on either related list is a good match. Start outdoors or with general plant questions in gardening; take leaf-level indoor care and windowsill problems to houseplants when that is what you mean.
