The cashew is the tree farmers plant because it refuses to die. It holds up through a six-month dry season that would flatten a mango, and that reputation is exactly the problem. Because cashews survive drought, almost nobody waters them,…
Passion fruit looks like a tough plant. It climbs a trellis, shrugs off heat, and fruits almost year-round in the tropics. Under that easygoing surface is one of the most drought-sensitive vines a farmer can plant. The roots are shallow,…

Coconut is one of the few crops where drip irrigation is still the exception, not the rule. Something like 90 percent of the world’s palms never see a drop of irrigation water. They get rain, and when the rain stops,…
