How to grow winter greens
Lynda Hallinan says the key from now on is that very little growth happens in cold, wet soil, so if you want a constant supply of salad greens through winter, grow them in plastic pots or troughs. They still need as much sunlight as possible, so position pots on a sunny deck, or indoors in a conservatory, or under a clear plastic polytunnel outdoors.
"A few years ago I did a lettuce trial for NZ Gardener and found that winter lettuces grow roughly a third faster if they are in plastic pots rather than in the soil"
She tells jesse it is important to avoid the pots getting waterlogged, and it can help to put them under the eaves for extra warmth and shelter, and water with liquid fertiliser diluted in warm water.
