Product Information

A. John Innes No 3 Mature Plant Compost does not contain any organic elements so shouldn’t be attractive to animals

Ensure the compost is moist at all times, but not wet. Feed with a high potassium liquid fertiliser such as tomato feed every fortnight during summer. A recently developed product that is suitable for use with ericaceous or ‘lime-hating’ plants. Peat-based or peat-free media with ‘added John Innes’ Can refer to either home-made garden compost or seed/potting compost: • Garden compost is a soil improver made from decomposed plant waste, usually in a compost bin or heap. It is added to soil to improve its fertility, structure and water-holding capacity. Seed or potting composts are used for growing seedlings or plants in containers - a wide range of commercially produced peat-free composts are available, made from a mix of various ingredients, such as loam, composted bark, coir and sand, although you can mix your own. Compost is also suitable for vigorously-growing plants such as tomatoes and chrysanthemums. The formulae contain loam, peat, sand, and fertiliser in varying ratios for specific purposes. These composts are used to grow seedlings for planting out, as well as long-lived plants which remain in containers.

Loam - Loam is the most important ingredient in all John Innes compost, supplying the main body of the compost. The loam supplies the nutrition needed for the base of the plant, which helps to absorb and release plant nutrients as required. The loam also contains micro-elements and organic matter, which provides a slow release of Nitrogen to the plant. The seedling mix is used to sow seeds and to grow young plants and cuttings until they are ready to be planted out. [4] Raised Beds SylvaGrow John Innes No.3 can be used as part of a raised bed medium for vegetable and strawberry growing. Simply mix one part SylvaGrow John Innes No.3 thoroughly with two to three parts loam or garden soil to gain a valuable addition of organic matter, sterilized loam and nutrients. Remember to supplementary feed as instructed above in ‘Potting On’ as vegetables are heavy feeders and will respond well. Some lilies, such as the Asiatic hybrids, root from the base of the bulb only. Others, including L. formosanum, L. lancifolium and L. longiflorum, produce roots not just from the base of the bulb but also from the stem just above the bulb – these lilies may need a deeper container. No. 3 contains the highest nutrient levels, and is used for growing mature plants such as shrubs and trees. [1] The base soil is amended with:

John Innes No.3 is a loam-based compost with a reduced peat mix and a plentiful supply of nutrients for heavy feeding plants, vegetables and fruit. The high quality peat used in the compost is from an exclusive Irish source and, combined with the loam, provides an ideal air/water balance, retains water whilst allowing adequate drainage, and is easy to rewet. Peat-free John Innes composts may be made by replacing the peat in the recipe with a substitute such as wood fibre, coir, or bark. [6] These substitutes tend to be less acidic than peat, so a smaller quantity of ground limestone is used to balance the pH level. [4] Cutting mix [ edit ] Peat - Sphagnum Moss Peat in the John Innes Compost increases the total porosity and improves both the aeration and the water-retaining capacity. Peat decomposes slowly into humus. Make a hole large enough to accommodate the item to be potted and insert, taking care that the growing medium is at about the same height on the stem as previously.Gardener, blogger and allotmenteer Bryony Willis, shows you how to grow lilies in containers for a stunning summer display. Preparing the container This mix contains double the amount of nutrient in John Innes No 1 to suit established plants. It is suitablefor most houseplants and vegetable plants in containers. To guard against waterlogging, standcontainersin the rain shadow of a wall or keep in an unheated greenhouse or in a shed. The potting mixes are used to grow different types of plants depending on their nutrient requirements. [1]

John Innes compost is a set of four soil-based formulae for growing media, developed at the former John Innes Horticultural Institution (JIHI), now the John Innes Centre, in the 1930s and released into the public domain.Plant single large bulbs (10-12cm (4-5in) diameter) into 20-23cm (8-9in) diameter containers, or plant three to four smaller bulbs (5-8cm (2-3in) diameter) into 23-25cm (9-10in) diameter containers. Allow 5cm (2in) between bulbs and use only deep containers. Planting depth Some lilies are lime-haters (e.g. L. auratum and L. speciosum), and should be potted into pure ericaceous compost. John Innes ericaceous compost is recommended. A. John Innes No 3 Mature Plant Compost is great for use with larger houseplants. For any other job choose a compost that is more specific to your requirements—for example Westland Houseplant Potting Mix.
