Keep up regular waterings in between. **Soil:** Dig in good amounts of [ActivGrow Soil Improver](https://rockypoint.com.au/products/activgrow/) prior to planting out. Seed can also be sown directly to garden beds, fill shallow trenches in prepared soil with [Seed & Cutting Mix](https://rockypoint.com.au/products/seed-and-cutting-mix/). **Harvest:** When the leaves fall over and wilt, you know it’s time to harvest your onions. Gently pull them from the soil and cut the remaining leaves off with a few centimetres from the bulb. Leave the bulbs in a warm, dry spot to dry out. Store dry onions in a cool, dry place in wire or mesh baskets.
