I’ve noticed that different kinds of plants are more resistant to sun scald than others. I’ve been hardening stuff off in a cold frame using week-long cycles of increasing sunlight exposure by 1-2 hours per day. Seems to work well enough. I’d like to increase the throughput and move things out a little quicker.
Are there situations where things don’t need to be hardened off? For example, if I move seedlings outside a few days after germination, do they need to be hardened? What sorts of plants need more hardening than others?
My Observations
Full week: Tomatoes, tomatillos
Less than a week: citrus trees, peppers
