Morphology
The meaning 'to grow outward and develop many branches' is directly derivable from 'bush' (a small woody plant) combined with the particle 'out' indicating outward expansion; this matches productive English patterns like 'branch out' or 'fan out'. Converting the noun into a verb meaning 'become bushy' is a regular, compositional operation, so a B1 learner who knows the constituents should be able to infer the meaning.
Etymology
The phrasal verb bush out comes from gardening: when a plant sends new stems and leaves outward it becomes a bush and spreads out, so gardeners often pinch the top shoots to help it 'grow fuller'. That's why bush out means 'to grow outward and develop many branches'.
