Soil Preparation:

Garden cress does well in all soil types as long as they are moist and nutrient rich. Before planting, incorporate 4-6 inches of well-composted organic matter and 1-2 lb of all-purpose fertilizer (16-16-8) per 100 square feet. Work compost and fertilizer into the soil to a depth of 6-8 inches.

Planting:

Garden cress is planted by seed. 

• Broadcast the seeds by randomly scattering them over the planting area or by mass planting them in rows.
• Plant seeds ¼ - ½ inch deep.
• Rows should be 3-4 inches apart.
• Once seedlings emerge, thin plants to 8-12 inches apart. 
• Re-sow seeds every 2 weeks for continuous supply of fresh leaves.

Irrigation:

Garden cress performs best if soil remains very moist. If planting in containers, make sure to water them every few days keeping the soil moist. Drought stress during growth will greatly reduce yield.

Fertilization:

Cress has very low fertilizer requirements due to the short growing time for the plants. For container grown plants, fertilize periodically with a soluble liquid fertilizer.

Fertilizing For a Successful Garden

Harvest:

Begin harvesting 2-3 weeks after emergence when leaves are 2 inches long. Remove the older leaves for immediate use and leave the young ones so the plant doesn’t stop growing. 

Problems:

Control weeds through regular cultivation, but avoid root damage that slows plant growth by damaging shallow roots. Weed control is particularly important during the first months of growth when plants are growing slowly and compete poorly. No specific diseases or insects affect the plant.
