「Tree under control」is perhaps the MULBERRY in which silk caterpillars were cultivated with strict control.「Many crotches」with「rotation emit down」some suggest as depicting slaves of a wealthy lord gathering silk caterpillar cocoons. For the lower elements, some fonts use「tree」while others use「hemp」or「screwing emissions.」It was important to not damage the fibers while gathering cocoons, so perhaps many slave crotches were perched upon tree branch crotches, sitting to enable carefully and patiently removing each individual cocoon.
Technically, the mulberry is a tree, but note that untended mulberry plants grow with densely-packed and closely-spaced branches beginning at nearly ground level, and so are often referred to by the misnomer of 'mulberry bush.' Silk-producing caterpillars especially enjoy ingesting MULBERRY leaves, appearing as mottled flecks of white all over the wood.
Eating ripe mulberries while picking them from the branches often causes long reddish-purple lines of juice to run down one's hands and forearms in stripes (see 条), especially as the picker loses concentration and begins to greedily grasp for more and more of the juicy, fleshy berries without exercising the necessary care and caution (桑!). Mulberry juice stains deeply. The skin of mulberry fruit is easily burst, and each plump berry contains many seeds.
It would seem the sages intentionally designed the lower elements to resemble both「tree」and「hemp」since mulberry trees and hemp were related in ancient China as sources of materials for clothing, so much so that one old nickname for China was the「land of mulberry and hemp」:「The mulberry plant was venerated because it was the food upon which silkworms fed, and silk was one of China's most important products. But silk was very expensive and only the very wealthy could afford silken fabric. For the vast millions of less fortunate [means], cheaper material had to be found. Such material was typically hemp.」

「Many crotches」being covered or wrapped with loincloths and/or poultices formed from these materials. Hemp and the mulberry tree were used to manufacture both cloth and paper, at first used in China to wrap, bind, and wipe「many crotches」of various sorts, those in feet and those in loins.
Leaves of the PAPER MULBERRY (a「tree with anal activity, toilet」榕) have been used to wipe and clean human and other animal anal orifices since before the beginning:「The tree, with extra-large leaves, soft on one side, rough on the other, is also a common source of woodland toilet paper.」
