SylvaGrow® John Innes Seed Compost

SylvaGrow John Innes Seed Compost

Perfect for seed sowing, encouraging germination and healthy root development. Also ideal for rooting cuttings.
John Innes Composts were originally developed at the John Innes Horticultural Institute in the 1930s. The four formulae were designed to cater for the different nutritional needs of plants ranging from seed sowing through to final containers. The range comprised Seed Compost and then numbers 1, 2 & 3, containing successively higher nutrient levels.
SylvaGrow John Innes Seed Compost, No.1, No.2 and No.3 offer gardeners an exceptional opportunity to use these great heritage composts with an updated peat-free formulation

Seed Sowing SylvaGrow John Innes Seed Compost is suitable for most seeds including the very fine such as Begonia or Impatiens. • Fill a seed tray evenly with SylvaGrow John Innes Seed Compost, tapping gently to settle and firm. • Lightly water with a fine rose. • Sow the seeds carefully, according to the packet instructions, cover with more SylvaGrow John Innes Seed Compost or vermiculite to the depth directed. • Cover the seed tray with glass or polythene and put in a warm place out of direct sunlight. • Remove the cover as soon as the seeds have germinated and ensure that the SylvaGrow John Innes Seed Compost is kept evenly moist at all times. • Prick out as soon as the seedlings are large enough to handle.

Pricking Out • When the seedlings are large enough to handle, gently tease them out of the growing medium using a dibber or pencil, taking care to handle only by the leaves. • Fill a suitable pot with fresh SylvaGrow John Innes Seed Compost or SylvaGrow John Innes No.1, use a dibber to make a hole and place the seedling in it, tapping the pot to settle the mix around the roots. • Water gently but thoroughly. • After 3–5 weeks, regularly apply a liquid feed, following the manufacturer’s instructions. Alternatively, at the time of pricking out, incorporate slow-release fertilizer granules according to the manufacturer’s instructions.

Cuttings • Ensure that the mother plant is well-watered before taking cuttings. • Fill a deep seed tray or pot with SylvaGrow John Innes Seed Compost and make a suitable hole with a dibber or pencil. • For larger, coarser-stemmed cuttings blend up to one part potting grit with one part SylvaGrow John Innes Seed Compost. • Prepare the stem or root cuttings according to type, ensuring that they are not allowed to dry out between cutting and inserting. Dip in hormone rooting powder/liquid if using. • Insert the cutting and gently firm the medium around it. • Stem cuttings need to be in a moist environment out of direct sunlight until they have rooted so either place in a cold frame, a covered propagator or cover with polythene, using supports to prevent the polythene from touching the cuttings. Root cuttings can be placed in a cold frame or sheltered spot out of direct sunlight and can benefit from a thin layer of grit on the growing medium surface. • Once the cuttings are well-rooted they can be potted on according to the instructions above.

Lime-hating, ericaceous plants SylvaGrow John Innes Seed Compost is not suitable for raising lime-hating, ericaceous plants. For these SylvaGrow Ericaceous is recommended.

OTHER ADVICE

  • Use in a ventilated place and avoid breathing in dust.
  • Always wear gloves when gardening and wash hands after use.
  • Close bag after use to avoid drying out and to prevent contamination.
  • White mould: under certain conditions a white mould may appear on the surface of some of the particles in SylvaGrow John Innes Seed Compost. This is entirely normal and not harmful to humans, plants or animals.
  • Store in cool, dry conditions.

The SylvaGrow packaging has been manufactured using at least 30% post consumer waste plastic. We are working with our suppliers to increase this level as quickly as we can. The bag is 100% recyclable but check regionally for local recycling options.

SylvaGrow John Innes Seed Compost is best used within the season of purchase and preferably within a year of manufacture. See side of pack for date of manufacture.

Fresh compost is always best – longer storage can cause a nutrient imbalance.
