Seed starting for beginners: keep the first batch small

Start a manageable seed batch by following the packet's timing, depth and growing conditions.

Choose a crop or flower you have room to grow on after germination. Seedlings need space beyond the first tray, so count available pots and suitable positions before sowing an entire packet. Keep the packet for its instructions and identification.

Set up a simple record

Label the variety and sowing date before filling the tray. Use an appropriate seed-growing medium and clean containers with drainage. Follow the packet's depth and temperature guidance; different seeds should not all receive the same treatment.

Keep the first batch small enough to inspect daily. Record when seedlings appear and any problem with drying or excessive moisture. This gives you useful information for a second batch instead of repeating the same conditions blindly.

Plan the next stage

Look up when and how that plant should be moved on. Check local conditions and plant-specific guidance before putting tender seedlings outside. A warm windowsill does not mean outdoor nights are suitable.

Avoid buying a heated propagator before confirming that your chosen seeds need the conditions it provides. Extra warmth is not a substitute for suitable light and careful moisture management.

Seed tray

Choose drainage and cell size suitable for the seeds you plan to grow. A reusable manageable tray is often more practical than a large kit that produces too many seedlings.

Seed compost

Read the bag's intended use and storage guidance. Buy an amount you can use sensibly rather than assuming the cheapest large bag will remain in good condition indefinitely.
