Grow cress for the easiest indoor salad harvest
Cress, sometimes referred to as garden cress but also broadleaf cress, peppergrass, pepper cress, mustard cress. This little fast-growing, edible herb is genetically related to watercress and mustard, sharing their peppery, tangy flavour and aroma. It’s also guaranteed to spice up your egg sandwich!
Cress is of the mustard family (Brassicaceae) a huge family of plants with four-petaled flowers; includes cabbages, broccoli and turnips. These tangy little herbs can be used in salads or as seasonings and garnishes.
Like it’s relative watercress, garden cress is packed with vitamin C, with one cup (50 grams) of garden cress providing a massive 35 milligrams of vitamin C. This provides nearly 60% of the recommended daily intake of vitamin C! Yay!
How to Grow Cress
Cress is very easy to grow outdoors, as the space occupied is soon available for other crops making it an ideal companion plant but it is most common to grow small pots in the kitchen. Cress can be grown in large quantities out of doors from Spring. Cress has no serious pest problems or diseases, simply sprinkle the seed on the ground in a shady spot and cover with sufficient fine earth to hide it from the birds.
You can grow cress indoors all year round, it is best sown on a wet flannel or paper towels placed in a shallow dish or tray. Brighten up your kitchen by finding a pretty dish or plate to grow your cress on, I love using Blue Willow styles on china from charity shops! Cress grown this way, it is never gritty as growing cress sprouts on moist paper towels instead of soil reduces the amount of nitrates the crop absorbs, which in turn makes the sprouts taste less bitter.
Garden cress is quick growing from seed, just sprinkle the seed thinly and keep the flannel wet. It will be ready for harvest 15 to 20 days after sowing. When the cress has two leaves, cut off close to the roots. Cut fresh for each serving.
If you want to have a constant supply of garden cress, sow seeds every 10 days and you will always have fresh garden cress available. As cress is a ‘cut and come again’ herb you should be able to cut your cress four to five times before it goes to seed.
