Plants exposed to direct sunlight before they’re ready can suffer from sunscald, which burns the leaves and can shock a plant (especially one that’s already in shock from shipping or being moved). In a worst-case scenario, plants that needed hardening off and didn’t get it can simply die.

What happens to plants when they are exposed to cold?

When a plant is exposed to weather that’s too cold for it, freezing damage comes into play. The water that makes up plant cells can freeze inside the plant, dehydrating them and wreaking havoc on the cell walls. Then when the weather warms and plants defrost, the sudden change results in cold injury, killing the affected stems and leaves. Even trees, which we tend to think of as hardy to cold weather, can suffer from cold injury if they’re young or have thin bark. That’s why it’s better safe than sorry when you’re dealing with new arrivals or young plants in your garden.
