Grow what you enjoy eating. Popular winter green crops include English spinach, silver beet, kale, cabbage and Asian greens. For salads include a few soft-hearted (repeat harvest) lettuce. All can be harvested as needed, leaf by leaf, rather than waiting for the crop to mature. Once the plant has at least eight good-sized leaves, gently pick one or two outer leaves.
To keep the plants in strong productive growth, water when the soil or potting mix is dry and regularly (every 7-10 days) feed plants with a liquid fertiliser for vegetables such as PowerFeed PRO SERIES for Tomatoes & Vegetables.
TIP: When planting water your seedling in with Seasol. Regular applications every week or fortnight will help create a strong root system and reduce stress from cold, frost, pests and diseases.
