Depends on cultivar and how intensely they will be managed. But for most I prefer 6-8ft in staggered double or triple rows about 5ft apart. For irrigation I prefer to use Netafim 1/2” poly driphose with the built in emmitters or a 1/2” solid poly hose with 2 shrubbler type emmiters about 2ft apart in a set of 2 for each mat. One hose per row is normally sufficient. For some of the higher turnover varieties I will occasionally use T-tape with 2ft emitter spacing, but its so fragile that its not good for bananas as you always have to move it for mulching and desuckering and so its more likely to get punctures over time.
