One of the easiest vegetables to grow from seed or seedlings is Silverbeet, once it gets started it is easy care and productive. It can be picked continuously and can be sown almost year round. This is a favourite green leafy vegetable easily grown in a humus rich well drained soil.
How to grow Silverbeet
Growing Silverbeet successfully requires a sunny position and can be grown almost year round in temperate areas of Australia. Prepare the soil well by digging in some well rotted compost and aged manure before planting. Rake over well to obtain a good even garden bed.
- If starting from seed we suggest soaking the seeds overnight to improve and speed up germination.
- Seeds can be sown directly or planted into punnets and started in a cold frame or greenhouse to give them some protection when young. Keep moist until they germinate.
- Plant out when they reach around 7cm tall (3 inches)
- Water well until established
- Readily available in a number or varieties and can be planted directly.
- Again moisture until established is essential
- Keep weed free
- Keep moist but not wet
We use a liquid seaweed or fish emulsion fertiliser combined with some vermicaste from the worm farm, seems to work well. As these are a leafy vegetable we also use a nitrogenous fertilizer, Dynamic Lifter is one.
- Ready for picking about 2-3 months after planting.
- Harvest the outer leaves as they reach the right size and the inner leaves will be ready a few weeks later
- Keep harvesting as long as the plant is productive
- Silverbeet is also known as Chard or Bietola. And our favourite varieties include:
- Swiss Ruby Chard,
- Green White ribbed Chard and
- Verde a costa bianca all are easy to grow from seed.
- Fordhook giant, a good strong growing type, a few smaller growing types are also available, perhaps more suited to container growing
