Garden cress prefers consistently moist soil. Water regularly, especially during dry spells, to prevent the leaves from wilting and becoming bitter. Avoid waterlogging the soil, as this can lead to root rot.

A light misting can be beneficial in hot weather.

Pruning is not typically necessary for garden cress, as it is grown for its young leaves and harvested before it becomes leggy. If plants do become overgrown, you can trim them back to encourage bushier growth.

Harvest regularly to promote continuous production.

Garden cress is primarily propagated by seed. Sow seeds directly into well-draining soil, either indoors or outdoors, once the risk of frost has passed.

Seeds germinate quickly, often within 7-14 days, and can be succession sown for a continuous harvest.

Repotting is generally not applicable to garden cress as it is typically grown as an annual for quick harvest or in shallow trays for microgreens. If growing in pots, ensure the pot size is adequate for the root system, but mature plants are usually harvested before needing to be repotted.
