Sowing Guide

Early Sowing/Module Sowing

Scatter the cress seeds over the surface (to give an idea of sowing density aim to sow seeds approx. 0.5 cm apart). The compost or kitchen towel must be kept moist but not sodden otherwise the seeds will rot. Lightly spray the surface with water on a regular basis. Paper towels tend to dry out faster than compost. To help keep the surface moist, after sowing cover the seeds with a layer of paper.
Place the container in a warm location (room temperature is fine) and keep away from direct sunlight at this point. In 1 - 2 days the seeds should germinate. As soon as germination starts remove the paper cover and move the container to a location with good daylight exposure, a windowsill is ideal.

Direct Sowing


Growing On

The cress should not need much attention other than ensuring the chosen medium does not dry out.


The cress will be ready to harvest in 7 - 14 days when they are about 5 cm tall. Cut the cress with scissors about 1 - 1.5 cm above the seed level. To keep the kitchen in good supply of fresh cress sow little and often, every 7 - 10 days. During the summer months cress can be grown outdoors in containers if preferred.


No germination - The temperature may be too cold for the seeds to germinate. The seeds may be out of date or has been stored incorrectly.
