Welcome to the Bunnings Workshop community @Sajee. It's fantastic that you've joined us and many thanks for your question.
Depending on the Yates Zero product you have used, there are different withholding periods before you can replant. If you've used the Zero Rapid, you'll need to wait one week, and if it is the Zero Super Concentrate, then you'll need to wait three weeks.
I hope that answers your question, but please feel free to let me know if there is anything else. We look forward to seeing your raised garden bed planted out and producing veggies and flowers.
