The shady corner
Bright shade / 30cm terracotta
No lily here — it wants sun. Plant water forget-me-not at the margin, sink a bunch of hornwort below, and let frogbit take the surface. Cooler water, slower growth, almost no algae.
01 — Miniature water gardens
A pond the size
of a bowl.
Twelve litres of still water, four plants and a bright corner. A bowl pond is the smallest garden that still behaves like a whole ecosystem — and the only one you can carry with two hands.
No pump. No filter. One quiet afternoon.
02 — Why small water works
Still water, lightly planted, finds its own balance in about three weeks.
Plants take up the nutrients. A few ramshorn snails do the tidying. Shade from the surface keeps the algae honest. Nothing needs plugging in — the only real rule is to top up with rainwater, never straight from the tap.
03 — Anatomy of a bowl
Four layers, one bowl.
Dwarf water lily
The only plant here that wants depth. Sit Nymphaea ‘Pygmaea Helvola’ 20–25cm below the surface on a stack of bricks, in a bowl at least 40cm across. Its pads cast the shade that keeps green water at bay, and it will flower from June to September on a single rhizome.
Depth 20–25cm / Full sun / One per bowl
04 — Planting ideas
Three bowls to copy.
Full sun, all summer
Six hours of sun / 45cm glazed
The classic. One dwarf lily set deep on bricks, a dwarf papyrus standing at the back, duckweed thinned weekly. Flowers from June, and a resident frog by August if you are lucky.
The tabletop bowl
Windowsill / Four litres
Four litres and nothing taller than a finger. Salvinia and a sprig of hornwort in a glass bowl, topped up with rainwater. Small enough to sit beside your coffee, alive enough to watch.
05 — The year in a bowl
Four small jobs, one a season.
Spring
March – May
Plant everything now. Divide the lily if its pads are crowding the rim, and top up with rainwater as the water warms.
Summer
June – August
Thin the floaters weekly, pinch off spent flowers, and watch the level — a shallow bowl can lose two centimetres on a hot day.
Autumn
Sept – Nov
Cut the marginals back to the water line and scoop fallen leaves out before they sink. Then let the bowl go quiet.
Winter
Dec – Feb
Leave it alone. Float a ball on the surface to hold a gap in the ice, and never break the ice by hand.
