Please explain why otherwise healthy parsley leaves would turn white and taste bitter. How can this be prevented? |
Older leaves may turn pale and fade, and a stressed or second year plant may taste bitter. Parsley plants can stress if the soil is allowed to dry out, when temperatures turn hot, or if the soil is not rich enough, or a combination of those factors. Second year plants will turn pale as part of their maturation process by which they then bolt or flower, set seed and die. |
