One does not normally think of bananas as a crop for arid regions. It is quite common, though, to see bananas being grown in monsoon climates where there is a pronounced dry season. These plantings often suffer during the dry season where water for irrigation is scarce. By planting in deep holes and using significant amounts of mulch, however, growth and production of banana plants can be improved. Pictured below are banana trees that were established as follows:
1) A 2.5 ft hole was dug
2) 18 inches of compost was placed in the hole
3) Banana plantlets (pups) were planted at or near the top of the compost (15 to 18 inches up from the bottom of the hole
4) 1 ft of mulch was placed around the plantlet
