Potting compost is specifically designed for growing plants in containers and should be used accordingly, keeping in mind it's not a soil improver.
Here's a breakdown of how to use potting compost effectively:
Choosing the Right Potting Compost
- General Purpose: Ideal for most container plants.
- Seed Sowing: Finer texture, low in nutrients to encourage germination.
- Cutting Compost: Often contains added ingredients to promote root development.
- Ericaceous Compost: Formulated for acid-loving (lime-hating) plants like rhododendrons, azaleas, and blueberries.
Key Considerations
- Peat-Free: Choose "peat-free" options to support sustainable gardening practices and protect peat bogs. Look for certifications for organic growing to ensure quality.
- Not a Soil Improver: Potting compost is formulated for contained environments and shouldn't be mixed into garden soil to improve it. Use garden compost or other soil amendments for that purpose.
Steps for Using Potting Compost
- Select the Right Container: Choose a pot with drainage holes appropriate for the plant's size and needs.
- Add a Layer of Drainage (Optional): For pots without adequate drainage holes, consider adding a layer of gravel or broken pot shards at the bottom to improve drainage.
- Fill the Container: Fill the pot with potting compost, leaving about an inch or two of space at the top.
- Planting: Gently remove the plant from its existing container. Loosen any circling roots. Place the plant in the center of the new pot, ensuring the top of the root ball is level with the surface of the compost.
- Backfill and Firm: Fill in the remaining space around the plant with potting compost. Gently firm the compost around the plant to eliminate air pockets.
- Water Thoroughly: Water the newly planted container thoroughly until water drains from the bottom.
- Ongoing Care: Water regularly, allowing the compost to dry slightly between waterings. Fertilize as needed based on the plant's requirements.
In summary, selecting the correct type of peat-free potting compost is crucial, followed by proper planting and ongoing care to ensure healthy plant growth in containers.
