Can you recycle compost bags & seed trays?
Compost bags: soft-plastic points (clean and dry). Rigid seed trays: with plant pots where collected.
Empty compost and bark bags are LDPE film — supermarket soft-plastic collection if shaken clean, kerbside film where rolled out. Rigid plastic seed trays and cell packs follow plant-pot rules: some garden centres take them back (taupe/non-black preferred).
Tips
- Garden centres increasingly host pot-and-tray take-back racks
