Speedy cooked Laura Calder’s gingered watercress several days ago and left the discarded stems in a bowl of water beside the sink. At this time of the year, the corner were the bowl sits gets plenty of sunlight in the afternoon.
A day later, the sad-looking wilted stems started to stand upright. Who would have thought? Two more days and the stems were growing leaves! Is it really that easy — and that fast — to grow watercress?
There are several tutorials on the web for growing watercress from seeds but I only found one — a video — that used stem cuttings from grocery-bought watercress.
Happy about the accident, I began changing the water daily. I’ve also started monitoring the growth of the leaves a bit more closely. When there are enough leaves to make a watercress side salad, I’ll cut off the leaves. But I will still leave the stems in the water to see how long they can continue growing. I may have to transfer the stems to two or three containers too.
