What to Look for in Compost and Food for Houseplants

Indoor plants have different needs compared to outdoor varieties. The compost must support a balance of moisture and airflow, while plant food should nourish without overwhelming delicate root systems. Look for:

  • Peat-free composts that are sustainable and suitable for indoor use
  • Good drainage and aeration to prevent root rot and overwatering
  • Moisture-retaining ingredients to keep soil balanced between waterings
  • Specialist mixes for different plant types, such as succulents or carnivorous plants
  • Houseplant food that provides complete nutrients for foliage, roots, and flowers

Tips for Using Indoor Plant Compost and Food

Indoor plants benefit from consistency and products that match their environment. Here’s how to make the most of your compost and feed:

  • Repot plants when roots outgrow their current containers or compost becomes compacted.
  • Use compost labelled for indoor or houseplant use — avoid heavy outdoor soil.
  • Apply houseplant food during active growth periods, usually spring and summer.
  • Avoid overfeeding — too much fertiliser can damage roots.
  • Use sphagnum moss for moisture-loving plants and terrariums.
  • Refresh compost annually to keep it rich and well-structured.
