Growing garden cress in small batches

Choose a clean, practical growing setup

Garden cress can be raised on suitable moist growing material in a shallow clean tray. The seeds need moisture but should not sit in stagnant pools of water. Choose a bright position that is protected from excessive heat and strong midday sun. Because the crop is usually harvested young and eaten fresh, hygienic handling, clean equipment and drinking-quality water are especially important.

Sow manageable amounts

Scatter a modest amount of seed evenly over the growing surface rather than piling it into thick clumps. Gently moisten it and monitor it daily; the surface should remain damp but not waterlogged. If you want a continuous supply, sow another small tray every few days according to your household use. Growth speed varies with temperature and light, so use the appearance of the seedlings rather than a rigid day count to decide when to harvest.

Prevent weak, mouldy growth

Seedlings stretched towards a dark window are less robust than those given appropriate light. Crowded, persistently wet and poorly ventilated trays can also encourage mould. If the crop smells unpleasant, shows suspicious fungal growth or becomes slimy, discard it rather than trying to rinse it clean. Wash and dry the tray before reusing it; reliable hygiene matters more than maximising output from one sowing.

Harvest and start again

Use clean scissors and remove leaves shortly before you need them. The tender seedlings lose quality rapidly after cutting and are best treated as a fresh garnish. Instead of repeatedly disturbing one dense tray, plan a sequence of small sowings and dispose of the used growing material appropriately. Keep notes about which position and sowing size provide a practical amount for your kitchen.

Before you begin: three practical checks

• Prepare a clean shallow tray
• Keep evenly moist without standing water
• Sow little and often for fresher harvests
