When the whole plant wilts, it’s usually caused by under watering, but can be from overwatering too.
How do I know if my cilantro needs water?
Generally speaking, the best way to determine how often to water your cilantro plant is to check the top half-inch of soil for dampness. As a rule of thumb, if it’s dried out, give the cilantro plant some water. If it’s still damp or moist in the top half-inch, then no need to water the cilantro plant.
Does cilantro need full sun or shade?
The plants need full sun for most of the year. The soil pH should be 6.5, which is slightly acidic. Keeping plants well-watered and mulched with straw keeps moisture in and soil temperatures lower. When it is too hot for cilantro to do well in the garden, find a location that has afternoon shade.
Does cilantro like to be wet or dry?
Since cilantro prefers consistently moist soil, start by watering seedlings with a spray bottle. In a setting with a lot of sun or more intense heat, check soil one to two times per day to ensure it is moist but not overly wet.
