Different rhubarb varieties have slightly different timetables. ‘Victoria’ is the reliable old friend who shows up punctually with a gentle, balanced flavor. ‘Crimson Cherry’ is the show-off with deep red stalks that look like they belong in a painting. Some varieties are ready earlier, some later. Check your plant’s tag if you kept it—or just look at your neighbor’s patch and copy them shamelessly. Gardening is 10% science and 90% spying on people who seem confident.
In the end, harvesting rhubarb is about trusting your hands and your calendar. If you feel a crisp snap in the spring, you’ve won. If it feels like tugging wet cardboard, walk away. And if you’re still unsure, just remember: if your grandmother would have made a pie out of it, you’ve waited long enough. Happy harvesting, you beautiful sour-stalk wrangler.
