Ah, you're asking about water climbing up tall trees? I've seen coconut trees do it, but with my own little tapioca plants wilting in the hot sun, I say it's not a strong enough pull sometimes! The science says it's a tube-and-suction system, but my thirsty fields tell me when that summer heat hits, that pull breaks down. My neighbour's big mango tree dropped half its small fruits last week – even it couldn't drink enough.
