>>2595914Perennials are capable of growing deep roots, while annuals never do – they live too short to outweigh the effort of producing them.
The notorious bindweed easily grows 2m deep. That's deeper than most trees.
I never managed to dig fully the roots of a sorrel, a chicory, a hollyhock, a horseradish, ... and that means they go way deeper than 1m.
So... if your shrub/tree has roots that reach 1m deep (that's half of your height), they can easily reach water while the annuals that merely reach 30cm just die out of thirst.
Effectively, for the last two summers my "lawn" was all sorrel, chicory and dry grass&clover (and somehow still alive fox-and-cubs).
>>2595888>oreganoHm... This may sound stupid, but does your oregano have the aroma (smell, taste) it's supposed to have? Mine somehow gradually lost the smell over the years, and even though every plant ID app says that it's oregano, it no longer has any kitchen use...
For now, I keep it just for the butterflies & misc insects that crowd it.
