Post #2 in the topic. The page date label is Sep 3; the year is not exposed in the retrieved page. The author reports the Monticello Citrumelo as a rare variety grown by Tom McClendon in Georgia, says the mother tree is quarantined, and says other growers have seedlings from fruit previously made available. The author characterizes those seedlings as mostly true-to-type; this is an attributed grower report, not independently verified pedigree or genetic-fidelity evidence.

Post #4 in the topic. The page date label is Sep 3; the year is not exposed in the retrieved page. The author says they are grafting a juvenile Monticello Citrumelo and may offer trees before fruiting. The reported year-3 fruit setting and possible year-4–5 holding/ripening apply to their mature grafted citrumelos generally; the post does not attribute that timing specifically to Monticello, identify the rootstock, or establish a universal bearing-age rule.

Summary from transcript: English automatic captions reviewed 0:02–22:54 of 22:56; raw timestamped transcript is retained in the Thomasville citrangequat research archive. At 10:41–11:13, McClendon identifies a tree as Monticello citrumelo, says he once thought it was Swingle, and compares its fruit with grapefruit. At 11:41–11:48, he refers more broadly to the late March 2023 freeze not setting back bloom or fruiting; the antecedent is not clearly Monticello alone, and no temperature, duration, protection, or particular-tree event details are given. Do not use this as a Monticello cold threshold.

Summary from transcript: English automatic captions reviewed 0:01–29:37 of 29:39. McClendon’s Monticello Citrumelo fruit is described as grapefruit-like and tart, with a slight sour-orange impression, floral/pine aroma, moderate juiciness, difficult peel, bitter zest, and empty seed coats. The final companion scorecard descriptors are low sweetness, tart, and moderately bitter; the catalog reference maps its language to catalog categories separately, rather than treating those category names as literal card labels. A spoken preference/light-bitter comment differs. The card gives 11 °Bx and pH 3.1; its 250 g figure is a provisional estimate, not a measured fruit weight. Fruit is attributed to Tom McClendon.

Summary from transcript: English automatic captions reviewed 0:03–4:05 of 4:08. At 0:08–0:30, McClendon describes a Monticello Citrumelo about 25 years old that he grew from seed received from a friend; the friend’s location is unclear in the captions. He reports abundant flowering. The clip does not establish an exact planting or fruiting year, parentage, rootstock, or cold threshold.
