Yesterday I planted out into the garden the watercress cuttings which I rooted in water some weeks ago. They have grown into reasonably-sized plants since being potted on into containers, seemingly able to cope with slug and snail attacks, so I thought I would move them on into the ground to see how they get on there.
They have a rather sprawling growth habit (perhaps because the weight of the stems are usually supported by water?) which caused them to trail out of their pots so that instead of forming upright clumps of leaves the stems now lie across the soil. I'm hoping they will root where they lie and spread about to fill the space I've planted them in - a semi-shaded patch of deep, damp soil near the pond.
