My diligence is paying off. The past two days have been chilly and wet, so I’ve kept the potted-up dahlias inside. Tonight I was curious to determine what—if anything—is happening beneath the two inches of slightly moist soil covering the tubers. So after some exploratory pokes and scrapes with my index finger, I discovered that all five tubers have the beginnings of sprouts. Hooray!
I might water them tomorrow morning, and then again I might not. The tubers feel nice and plump; no signs that they’re drying out at all.
This is exciting.
