Clover John Innes No.3 Compost 25L is a traditional loam-based compost formulated for the final potting of established and mature plants. Designed for plants with greater nutritional demands, it provides a substantial growing medium for tomatoes, chrysanthemums, shrubs, tubs, baskets and a wide range of established fruit, vegetable and ornamental plants.
John Innes No.3 represents the most nutrient-rich stage of the traditional numbered John Innes potting compost system. It is intended for established plants that have progressed beyond the earlier propagation and potting-on stages and require a growing medium suited to continued development in larger containers.
The loam-based formulation gives the compost useful weight, structure and stability, making it particularly well suited to mature container plants, shrubs and vigorous crops that may remain in the same pot for an extended period.
Supplied in a 25 litre bag, Creation Horticulture supplies 80 x 25L bags per full pallet.
Why choose Clover John Innes No.3 Compost?
- Traditional John Innes No.3 formulation - a proven loam-based growing medium for established plants.
- Designed for final potting - particularly suited to mature plants moving into their longer-term containers.
- Higher nutrient formulation - designed for established plants with greater nutritional requirements.
- Loam-based structure - provides body, weight and stability within larger pots and containers.
- Ideal for tomatoes - Clover specifically recommends No.3 for mature tomato plants.
- Suitable for shrubs - a strong choice for established woody plants grown in containers.
- Suitable for tubs and baskets - provides a substantial growing medium for mature seasonal planting.
- Ideal for established ornamentals - suitable for chrysanthemums and a wide range of mature flowering plants.
- 25L bag - convenient for repotting individual mature plants and larger containers.
What is John Innes No.3 Compost used for?
Clover John Innes No.3 is specifically formulated for the final potting-on stage of mature plants. Clover identifies the compost as suitable for:
- Tomatoes
- Chrysanthemums
- Shrubs
- Tubs and larger containers
- Baskets
- Established fruit plants
- Mature vegetable plants
- Established ornamental plants
Its stronger formulation makes it particularly useful once plants have moved beyond seedling and young-plant stages and require more substantial nutrition and root support.
What does John Innes No.3 mean?
John Innes is not a brand name. It refers to a traditional system of loam-based compost formulations designed around different stages of plant development.
Within the numbered John Innes potting range, the nutrient level increases as the number rises. This allows growers to select a formulation that better matches the maturity and nutritional requirements of the plant.
John Innes No.3 is intended for established and mature plants and is traditionally used for final potting, where plants may remain in the same container for considerably longer than they would during propagation or early potting-on.
John Innes No.1, No.2 & No.3 - what's the difference?
The numbered John Innes composts are designed for progressively more established plants.
| John Innes No.1 | Designed for sensitive subjects, pricking out seedlings and bedding plants. |
|---|---|
| John Innes No.2 | Designed for potting-on established bedding and vegetable plants as their nutritional requirements increase. |
| John Innes No.3 | Designed for final potting of mature plants, including tomatoes, chrysanthemums, tubs, baskets and shrubs. |
Choosing the appropriate stage helps match the growing medium to the plant rather than using the strongest formulation unnecessarily for very young plants.
Ideal for mature container plants
Mature plants grown in containers need more than simply a space for their roots. The growing medium must provide physical support, retain appropriate moisture and nutrients and remain sufficiently stable as the plant develops.
The loam content of John Innes No.3 gives it considerably more body than many lightweight potting media. This additional weight can also be useful when growing larger or top-heavy plants in pots, helping provide a more substantial base around the root system.
It is particularly useful for plants that are reaching their final container size and will not be repeatedly potted-on during the same growing cycle.
John Innes No.3 for tomatoes
Tomatoes are specifically listed by Clover as a suitable crop for John Innes No.3. Once established, tomato plants develop substantial root systems and become increasingly demanding as flowering and fruit production progress.
No.3 provides a substantial loam-based medium for established tomato plants grown in suitable containers. As with any container-grown tomato crop, watering and nutrition should continue to be monitored throughout the season.
Mature fruiting plants can eventually require supplementary feeding as the nutrients available within a finite volume of compost are used.
John Innes No.3 for shrubs & long-term containers
Established shrubs can remain in containers for several seasons, making the physical properties of the growing medium particularly important.
A loam-based compost provides useful weight and structure around established root systems, making John Innes No.3 a popular choice for suitable mature shrubs and other long-term container specimens.
When repotting, choose a container with suitable drainage and avoid moving a plant into a dramatically oversized pot. A modest increase in container size generally makes moisture management easier while providing fresh rooting space.
How to use Clover John Innes No.3 Compost
Choose a clean container with adequate drainage and sufficient space for the plant's established root system. Add fresh compost to the base before carefully removing the plant from its previous pot.
Position the plant at approximately the same planting depth at which it was previously growing. Fill around the root ball with Clover John Innes No.3, gently firming the compost to remove large air pockets without heavily compacting the growing medium.
Water thoroughly after potting and allow excess water to drain. Continue to monitor moisture according to plant requirements, container size, weather and growing conditions.
What about acid-loving plants?
Standard John Innes No.3 should not automatically be used for plants that specifically require acidic growing conditions.
Rhododendrons, azaleas, camellias, heathers and other lime-hating plants have specialist pH requirements. For these plants, choose an appropriate ericaceous growing medium rather than assuming a standard mature-plant compost is suitable.

This staged approach allows gardeners and professional growers to select a loam-based compost appropriate to the maturity of the plant and its changing nutritional requirements.
25L John Innes No.3 for garden centres & professional growers
The 25L format is convenient for mature container plants, shrubs and final potting applications while remaining manageable for retail customers and professional users.
Creation Horticulture supplies 80 x 25L bags per full pallet, providing a total nominal growing-media volume of 2,000 litres per pallet.
