They may make you cry, but onions are worth the tears! They can impart such a sweet or savoury flavour to your dishes, depending on how they’re cooked or used. There are many varieties, too – brown, gold, red and white – each with their own unique taste. Before planting, check your climate zone to see which varieties are best for growing in your area.


How to grow onions in a garden

  1. Choose a spot that receives plenty of sun. Prior to planting, improve your soil by digging in Yates Thrive Natural Blood & Bone with Seaweed.  
  2. Dig a narrow furrow, sow seeds and cover lightly with Yates Black Magic Seed Raising Mix. Onion seeds only need to be sown 6mm deep, so don’t be tempted to plant them too deeply otherwise they won’t be able to grow. Firm down and keep moist. 
  3. Once seedlings are 10-12cm tall, thin them out to 10cm spacings to give them room to grow. Don’t waste the onions you thin out – they can be used like spring onions!
  4. Feed every couple of weeks with Yates Thrive Natural Fish Seaweed+ Plant Food Concentrate to help cultivate good, healthy growth.
  5. Harvest when the leaves wilt and fall over. Gently pull the onion out of the ground, cut the leaves off a few centimetres above the bulb and then leave them in a warm sunny spot to dry out. Once the skins and roots are dry, they can be stored in wire baskets and mesh bags in a cool dry spot.

Growing tips

  • You don’t have to wait for all the onion bulbs to be full sized before you harvest them. You can pick and use smaller bulbs and leave the rest to grow bigger.

  • Onions may go to seed if they are not planted at the right time of the year, so make sure you check the label before planting so you don’t spoil your crop!
