John Innes No.3 for Mature Plant Compost is a nutrient-dense blend, ideal for supporting the needs of established plants, including mature shrubs, trees, climbers, fruit trees, bushes, vines, and vigorous growers like tomatoes and chrysanthemums. Its high nutrient content promotes strong, sustained growth and vibrant health, while the well-aerated structure supports extensive root development and ensures excellent drainage. This compost helps retain moisture effectively without the risk of waterlogging, reducing the likelihood of root rot. It’s particularly well-suited for long-term potting, providing the ongoing nutrition mature plants require when remaining in the same container for extended periods. As the richest compost in our range, it delivers triple the nutrient levels found in early-stage composts, making it the ideal choice for plants that demand more as they grow and develop. Mature Plant Compost offers structure, moisture balance, and high nutrient levels—giving your established plants the best conditions to thrive over the long term.
