J. Arthur Bower's John Innes are traditional, superior quality soil-based composts. John Innes composts have been widely used by gardeners for over 60 years and are valued for their consistantly good performance. J. Arthur Bower's John Innes Ericaceous has been developed to match the needs of acid loving (lime-hating) plants such as rhododendrons, camellias, azaleas and heathers.

Quality Ingredients

 Loam is the most important ingredient as it provides a natural reservoir of plant foods, trace elements and contains some organic matter which releases nitrogen slowly to the plant. The loam in J. Arthur Bower's John Innes is screened and sterilised to avoid any soil-borne diseases and insects.

 The sphagnum moss peat in John Innes compost improves both the aeration and water-retaining capicity, which enables the compost to make maximum use of the nutrients and trace elements in fertilisers.

 • Lime-free grit sand is included to allow excess water to drain from the compost and so prevent waterlogging. It also adds weight and provides stability for pot grown plants.

 The compound fertiliser in John Innes provides the wide spectrum of plant nutrients needed for healthy growth. These include nitrogen for leafy growth, phosphates for root development, potash for flowering and fruiting and trace elements for colour and flavour.

How to use

Taking Cuttings 

 • Fill the pot and insert cuttings, spaced so that the leaves do not touch.

 • Gently firm the compost around the cuttings.

 • Water in using a fine rose.

 • To maintain humidity fit a plastic bag or dome cover over the pot or place in a propagation unit.

 • Keep in a warm well-lit place, out of direct sunlight.

 • Water when the cover looks dry or if cuttings wilt. 


Potting-on Plants

  Before re-potting, remove any moss or lichen that may have formed on the old compost, water plant well and allow to drain.

  Put fresh compost in the bottom of a new pot.

 Turn the old plant upside down and tap pot sharply to release.

 Place the plant in the middle of the new pot and add more compost, firming lightly around the root ball. 

 Leave a space of at least 1cm below the pot rim to allow adequate space for watering. 

• Feed with an ericaceous liquid plant food after 2 or 3 months, or earlier if the container becomes filled with roots.

Planting Out

• Dig a hole large enough for the compost to completely surround the roots. 

• Line the hole with compost, place the plant in posistion and fill with more compost.

• Firm gently and water well.
