Hardiness Zone: 3-12
​Soil Preference:
Soil pH: 
4.9-8.0, Ideal 6.0-6.7. Cress will tolerate most soil types, but will do best in fertile, moist soil that drains well.

Soil Preparation:
Standard Mix, 5 pounds per 100 sq. ft., in top 8" of soil, 1 time: 
A standard mix will supply all necessary nutrients. This is a mix of various amendments intended to supply all of the nutrients plants may require. It is usually incorporated into the soil prior to planting. The mix consists of:


  • 4 parts cottonseed meal (this is high in nitrogen and relatively inexpensive)
  • 2 parts colloidal phosphate or bone meal (for phosphorus)
  • 2 parts wood ash or 3 parts greensand or granite dust (for potassium)
  • 1 part dolomitic limestone (to balance pH and add calcium and magnesium)
  • 1 part kelp meal (for trace elements)

Mix these together thoroughly. You can do this all at once, or you can store them separately and mix as needed.

Compost (Nitrogen), 2" in top 8" of soil, 1 time: Incorporate 2" of compost into the top 8" of soil.
When Cool, Warm: Cress grows best in moist soil with cool temperatures. In warmer temperatures Cress can flower before leaves are large enough to harvest, so it should be grown in partial shade during the summer.

When outdoor temp: 45°F to 80°F, optimal temp 60°F to 70°F

When min soil temp: 50°F. Seeds can be sowed once the soil can be worked. Germination may take up to 14 days at temperatures below 50˚ F.

Seed Depth: 0.125"-0.25". Cover seeds with about 1/8 to 1/4" of soil.

Spacing: 2.0"-4.0", 16 plants per sq ft. Give plants a final spacing of 2 to 4" apart.

Spring Crop:
2-4 weeks before Last Frost Date: 
Cress grows so quickly that it's best to start it outdoors directly in the garden.

Sowing Directly: Sow seeds 1/8 to 1/4" deep about 1" apart and keep moist. 

Containers: Cress has shallow roots and does not need to be grown in deep containers - 4" tall flats are perfect. Sow seeds 1/8 to 1/4" deep about 1" apart and keep moist.

Fall Crop:
10-12 weeks before First Frost Date: 
Cress grows so quickly that it's best to start it outdoors directly in the garden. Cress needs cool weather, so wait until the summer temperatures drop and fall temperatures begin. Wait until its about 70˚ F outside.

Sowing Directly: Sow seeds 1/8 to 1/4" deep about 1" apart and keep moist. 

Containers: Cress has shallow roots and does not need to be grown in deep containers - 4" tall flats are perfect. Sow seeds 1/8 to 1/4" deep about 1" apart and keep moist.

Support: No.
Cress is pretty easy to grow, but it doesn't last long before it bolts. In hot weather it bolts pretty quickly.

Water Needs: Moderate. Keep soil evenly moist.

Fertilizer Needs: Moderate. Prefers rich soil.

Watering, regularly: Water, 0.5 inch, regularly, 2 times a week. Keep soil moist at all times. If the plants do not receive adequate moisture they will be far less productive.

Weeding, regularly: regularly, every 2 weeks. Keep Cress free of weeds, especially while young.

Thinning, when 3" tall: Before plants crowd one another, thin plants to stand 2 to 4" apart. Eat your thinnings - they're delicious!

Support: No
​Store cress in a plastic bag in the refrigerator for a few days.

Storage Req: Refrigerator 
Storage Temp: 35-40°F 
Storage Length: 1-5 days
The flowers have both male and female parts and produce seed readily (often too readily as premature bolting can be a problem). Put the ripe plants in a paper grocery bag to dry out and then crush them to release the seeds.

Seed Viability in Years: ​4 - 5 Years

Culinary

Taste:
Young shoots are mild, while mature leaves and dried seeds pods become quite intense. The flavor is initially grassy and earthy, but then develops into a strong spicy, peppery flavor. Edible at all stages of growth, the sprouts, mature leaves, flowers and even dried seedpods each offer a distinct level of spicy heat.

Culinary Use:
Peppercress may be eaten raw or cooked. The young sprouts and baby greens are best used raw in salads, especially when mixed with mild butter lettuce or hearts of romaine. They are tender and blend easily into pesto, vinaigrettes, marinades and chimichurri. Larger leaves may be sautéed, blanched or braised and are an excellent complement to the sweet flavor of young spring vegetables.

Medicinal

​The leaves are antiscorbutic, diuretic and stimulant. The plant is administered in cases of asthma, cough with expectoration and bleeding piles. The root is used in the treatment of secondary syphilis and tenesmus. The seeds are galactogogue. They have been boiled with milk and used to procure an abortion, they have been applied as a poultice to pains and hurts and have also been used as an aperient.

Cress is rich in iron, calcium, and Vitamins A and C.

Health Benefits

Potential Anti-Cancer Effects:
A study funded by Australia's Rural Industries Research and Development Corporation (RIRDC) assessed the anti-cancer potential of a number of Brassica vegetables, including cress. For each tested vegetable, an anti-cancer score was calculated based on the vegetable's glucosinolate content. While glucosinolates themselves have limited biological activity, their metabolites – particularly isothiocyanates – appear to have significant cancer-fighting potential due to their ability to promote the elimination of potential carcinogens from the body. However, many Brassica species, including cress, contain epithiospecifier protein (ESP), a compound that promotes the conversion of glucosinolates into nitriles (which have no anti-cancer properties) rather than isothiocyanates.

However, despite containing ESP, cress still had significant anti-cancer potential relative to many other vegetables tested. Even when the potential effects of ESP were take into account, cress still appeared to have as much or more anti-cancer potential than radishes, turnips, cabbage, kohlrabi, Chinese broccoli, mizuna, komatsuna, or choy sum.

A Powerhouse of Carotenoids (Good for Your Vision and Eye Health):
If you're still not impressed by the nutritional value of cress, then consider this: by eating just one ounce of cress you'll be supplying your body with nearly 40% of the Daily Value of vitamin A (in the form of carotenoids). As you may already know, vitamin A and carotenoids are considered one of the best nutrients for the eyes due to their ability to reduce the risk of impaired night vision, cataracts, retinitis pigmentosa, and even age-related macular degeneration, a common cause of blindness in older people.

Cress Contains Even More Vitamin C Than Oranges:
So you thought oranges are the ultimate vitamin C champion? Well, guess what, fresh cress contains much more vitamin C than fresh oranges! Just one ounce of cress delivers a whopping 32 of the Daily Value of vitamin C – that is 7% more than what you would get from an equal amount of fresh orange. Vitamin C is crucial to keeping you skin, bones, and gums strong and healthy, but it also helps prevent iron deficiency by improving your body's capability to absorb iron from foods.

Eating Cress May Provide Cardiovascular Benefits:
Scientific research suggests that vitamin C may also help keep your cardiovascular system healthy, so adding cress to your diet may be a smart thing to do if you're trying to improve your cardiovascular health. A study published in the April 2004 edition of the Journal of the American College of Nutrition reported that the study participants who received a daily supplement containing 500 milligrams of vitamin C experienced a 24% drop in their plasma CRP levels after just two months. Recent evidence suggests that CRP levels (C-reactive protein levels) are a good measure of a person's heart disease risk, potentially even better than cholesterol levels.

In addition, cress is supercharged with vitamin K, another nutrient that is thought to play a key role in maintaining cardiovascular health. By adding just half an ounce of cress to your salad you'll be covering almost 100% of the Daily Value of vitamin K!

Smile, Cress May Be Good for Your Teeth, Too!:
Glucotropaeolin, one of the main glucosinolates found in cress, is a pre-cursor to benzyl isothiocyanate (BIT), a compound that may help fight dental caries. A study published in Microbios Letters in 1988 found that BIT inhibited the growth and acid production of Streptococcus mutans, a bacterium that has been linked to the development of dental caries.
 It is cultivated in Ethiopia for the plentiful oil extracted from its seed. The oils is both edible and used as lighting fuel.
