plum seeds germinating last may

I found some in a bed that were planted two years before, the rest I let germinate in bags of damp peat moss in our root cellar before potting up. The seeds can have a long dormancy so you need to cold stratify a few...

plum scion wood bundles that were cut early, just checking in on the moisture
