leaf mold; humus; mulch
Decomposed leaves and organic matter used as a soil conditioner or mulch in gardening and agriculture.
I mixed leaf mold into the garden soil and made a flower bed.
Mulching with leaf mold makes it harder for weeds to grow.
Compound of 腐 (ふ, 'rot, decay'), 葉 (よう, 'leaf'), and 土 (ど, 'soil'). The reading ふようど reflects a sound change from ふ + よう + ど.
