I'm nearly ready to dig a hole to sink my preformed liner (1m diameter).
Does anyone know if I can get away with not planting until the spring? The RHS info says plants will go dormant over winter and spring is the best time to plant up a new pond. They also say that autumn/ winter is the best time to install a pond 
I was hoping to Freegle a few plants in the spring when people divide them.
Should I get an oxygenator in immediately to stop the pond going slimy and provide some habitat?
