The coconut is a great fruit. We all know how delicious the flesh is and the water is nutritious with lots of potassium but also the outside husk is very beneficial. It's used in textiles to make ropes and it can be grounded down to really fine particles which are not really used in textiles, but are great for use in the garden. Coconut husks are also used as coarse chips, great as a mulch in planting beds and in the garden.
