FAQs
What is John Innes No. 2 Compost?
John Innes No. 2 is a traditional loam-based compost, providing a balanced mix of nutrients and a stable structure ideal for potting medium-sized plants and young plants.
Can I use this for acid-loving plants?
It is generally not recommended for acid-loving plants like azaleas or rhododendrons as it has a neutral to slightly alkaline pH. You would need to amend it significantly with ericaceous materials.
How long do the nutrients last?
John Innes No. 2 provides nutrients for approximately 4-6 weeks. After this period, regular feeding with a suitable plant fertilizer may be necessary.
Is this compost suitable for seed sowing?
No, John Innes No. 2 is generally too rich for delicate seedlings. For seed sowing, John Innes No. 1 or a dedicated seed compost is recommended.
What does the 25L volume mean?
25L refers to the volume of compost in the bag, indicating the quantity available for use in potting.
Can I mix this with other composts?
Yes, you can mix it with other composts, such as peat-free alternatives or grit, to adjust the texture and drainage for specific plant needs.
Troubleshooting
Plants appear wilted after potting
Ensure the compost is adequately moist. Water gently and allow excess to drain. If the plant was dry before potting, it may take time to rehydrate.
No signs of new growth after several weeks
Check for adequate light and watering. Ensure the plant is in the correct season for growth. The compost provides initial nutrients, but long-term feeding may be required.
Compost seems too dense
This is characteristic of loam-based composts. Ensure pots have good drainage. For plants that prefer lighter soil, consider mixing with perlite or grit.

Setup, Compatibility & Care
Setup: This compost is ready to use straight from the bag. Simply open the bag and fill your pots or containers. Ensure pots have adequate drainage holes.
Compatibility: Suitable for most medium-sized flowering plants, shrubs, vegetables, and houseplants that prefer a standard potting medium. It is generally not recommended for ericaceous (acid-loving) plants like rhododendrons or blueberries without amending the mix.
Care: Keep the compost bag sealed when not in use to retain moisture and prevent contamination. Store in a cool, dry place away from direct sunlight and frost. Water plants regularly after potting, ensuring the compost remains consistently moist but not waterlogged.
