2023 - Full bloom 5/19-25, mid 20's freeze 5/25-27. But set a dozen nice plums. Mid August 7 dropped in high wind. End August remaining 3 healthy plums ripe. Flesh sweet and juicy, quite mild, skin just lightly sour. (Alderman's fruit not ripe yet.). Tree fairly vigorous, pruned quite a bit. Looking good. 2022 - Growing vigorously (as is Alderman) like all of these Japanese cross plums (much larger than photo above!). Had a few blossoms and one fruit! August 26 noticed it had split, likely over-ripe. Earlier than Gracious. Large, mild red color, some insect damage on bottom. Slip skin, juicy, very mild. Likely tastier if picked earlier, not too exciting at this point. 2021 - Hot, dry spring. 5/18-21 all plums, including Grenville (in early group), in full bloom. 5/27 four nights freezes 24-30 deg. No fruit. Good summer growth. 2020 - 5/26 full bloom. 5/31 freeze 25 deg. Set one fruit! 9/5 looked ripe, came off easily. Small, red with yellow flesh. Very nice flavor, mild, skin not as sour as most others. 2019 - Full bloom. 9/15 Noticed a small ripe plum! Came off w/ touch. Red-orange skin, tough but not sour. Yellow juicy sweet flesh. Lot like Gracious. 2018 - Full bloom, no fruit. vigorous growth; summer prune to even up. Mostly long vig. new shoots. Many fruit buds (next year??). Very open. Looks good. Aldrman doing well, too. Stop mulching; it’s plenty vigorous.
2017 - Vigorous growth. Cut off low branch and pruned & tipped 2 scaffolds to reduce fruit load (full of spurs). (NOT necessary...!). Full blooming 5/22 with rest. No fruit. Summer pruned, also early Sept cut back overly vig shoot. Light blight, significant aphid damage. Grafted Alderman to sw shoot to be 1/3 of tree. Slow to start but grew well (see Alderman). 2016 - Grew well, long strong shoots (maybe should have shortened last year?). Prune to 3, shorten a little. Very strong growth. 7/25 pruned some off. Shothole/red leaves but good growth. 2015 - Scion from Fedco - grafted to a strong local sucker, likely american plum rootstock sucker. Grew very well. Online Notes: Late Summer. Large dark rosy-red clingstone fruit, resembling Burbank. Yellow flesh has excellent flavor. Vigorous early-blooming tree. Most of the hybrid plums were developed using Asian varieties crossed with P. americana. Grenville was bred using P. nigra, the extremely hardy Canada plum. Pollination requirements are the same as other hybrids, but the tree and fruit will be somewhat different from the others. Like P. nigra, very hardy. Z3. Copyright © Susan Robishaw |
