John Innes No 3 Mature Plant Compost is the perfect medium for your mature plants. The level of peat it contains makes for better moisture and nutrient retention, and for an all-round more consistent growing medium.
This compost provides a high amount of nutrients, more than the Potting On Compost, the ideal amount for mature plants. The water holding capacity and aeration is still an ideal balance, providing the perfect environment for a healthy root system and sustaining longer plant life.
John Innes No 3 Mature Plant Compost has a comprehensive range of nutrients for strong and healthy plant development and the pH level is neutral to slightly acidic, the optimum level to ensure the correct amount of nutrients are freely available for uptake.
