Dear All, I clicked on the wrong key on my conversion calculator. My husband says that I exaggerate to make a point at times. But this was just a quick mistake: "Redwoods are not deciduous, but they certainly have the root action to extend to reach any moisture to 30 ft (abt. 100 meters) away." should be "Redwoods are not deciduous, but they certainly have the root action to extend to reach any moisture to 30 ft (abt. 9 meters) away." Redwood roots are amazing, but probably not that amazing. Thank you Bob for pointing out my mistake. Mary Sue
