Use direct sowing when roots dislike disturbance
Carrot, radish and many beans are usually simplest when sown where they will grow. Direct sowing avoids transplant damage but requires you to keep a shallow seed zone in suitable condition through germination.
Large seeds are easier to space and recognise. Fine seed may be washed out by heavy rain or dry rapidly in heat, so timing and temporary protection matter.
Use seedlings to save part of a short season
A healthy seedling can move a slow crop such as tomato, capsicum, broccoli or cauliflower through its earliest stage. It does not remove the need for the right outdoor temperature, root room or hardening before exposure.
Choose compact, vigorous plants with a clear crop and variety label. Avoid severely root-bound, stretched or damaged seedlings simply because they are already large.
Treat provenance as a biosecurity decision
Australian Government guidance says to obtain seed and planting material from reputable Australian suppliers and not plant food products intended for eating. Imported seed and movement of plants, soil or produce can be restricted by national, state or territory rules.
Do not plant unsolicited seed, supermarket food, unknown cuttings or material carried across a quarantine boundary. Check BICON or the relevant state and territory authority when ordering or moving material.
Keep the packet with the garden record
The packet identifies variety, batch, sowing guidance and supplier. Keep it until the crop is finished and note the sowing date. If a plant performs unexpectedly, this evidence is more useful than relying on memory or the generic crop name.
- Check local suitability and maturity time.
- Check whether the crop is normally direct-sown.
- Check biosecurity and movement restrictions.
- Reject damaged, unlabelled or suspect material.
