The amount of water has never killed a citrus tree, as long as the root system has good levels of oxygen. Medium's like pine, bark, CHC and cedar all provide excellent aeration. There is no need to over flood the tree, but keep the moisture level high. Anyway that is what I would do. The best to you and your tree. - Millet (523-)

Will do! Thank you! On that note, I have one more question I was going to post in the cultivars section, but, it may be medium related (as so much seems to be)... Since potting my Oroblanco, 7 weeks ago, there has been no change in the tree...no new growth nor any color changes in the leaves (thankfully). I was thinking grapefruit may just be less vigorous? The Washington Navel and trovita I potted around the same time have new growth with the trovita even sporting new fruit!
