Fill clean trays or pots with clear drainage.
- Monitor moisture
Water gently and maintain moisture appropriate to the crop.
After about 4–6 weeks, check nutrients and begin supplementary feeding if needed. This label direction is a review point, not a requirement to feed automatically. Species, growth and nutrients already available remain decisive.

Seed Compost
Ready-to-use sowing compost for propagation in containers
Consider seed and roots together
Check the container and planting space
Choose clean trays or pots with free drainage, fill loosely and firm lightly.
Young plants and aftercare
After about 4 to 6 weeks, check nutrient levels and start supplementary feeding if needed. Account for the starter feed in the compost.

A good start in a small container
Start small. Follow the growth.
A propagation tray provides a small individual root zone for each young plant. Match light, temperature and moisture to the species sown. Check the plants regularly rather than treating every crop on the same timetable.
A fine growing medium for seeds and young roots: this peat-containing seed compost includes sand, raw clay and declared nutrients. Match sowing, moisture and temperature to the crop. Choose 2, 6 or 10 litres to suit your propagation containers.
Fresh growing medium, clean containers and suitable seed treatment work together. Compost alone sets neither germination temperature nor light requirements.
Keep fine roots in view
Small propagation containers respond quickly to heat, airflow and water. Fill with compost gently and check actual moisture. A bright window cannot compensate for persistently wet roots.
Repotting: the complete process
When seedlings become young plants
Young plants in individual pots beside this seed compost. The photograph illustrates a growing situation; the separate eight diagrams explain gentle repotting.
The eight shared diagrams show repotting a rooted young plant. For sowing, also follow the species-specific instructions; this image sequence does not depict seeds.
-
Choose the next growth stage
The illustrated sequence shows moving a rooted young plant. Prick out when the plant is strong enough and needs more space; seed leaves alone do not set one date for every species.
Sowing also requires the correct species-specific depth, light or darkness and germination temperature. Check the seed packet and propagation guide.
-
Prepare clean containers
Choose clean modules or small pots with clear drainage holes. Match the new root space to the young plant; very large containers often stay wet for longer after watering.
Take only the compost needed from the bag and gently loosen large clumps. The required volume depends on the container and existing root ball.
-
Keep drainage clear
The shared drawing shows a container setup with drainage material. Small propagation pots do not require a thick extra layer. Clear holes and a freely draining arrangement matter most.
Do not leave water permanently standing in the saucer. If water-permeable material covers a hole, it must not block the outlet.
-
Release the young plant gently
Ease a rooted module out carefully. When pricking out individual seedlings, hold a leaf where possible and support the roots with a suitable tool.
Avoid squeezing the delicate stem and do not leave roots exposed to drying. Assess seriously diseased or rotting seedlings separately rather than placing them among healthy plants.
-
Set the appropriate depth
Prepare a hole and place the roots without sharply bending them. With an intact root ball, initially retain its existing surface level.
Some species can be planted deeper, but this is not a rule for every seedling. Do not bury the growing point, sensitive stem base or leaf rosette.
-
Close the space around the roots
Ease compost towards the roots and close larger air gaps gently. Do not compact it hard; fine roots need an evenly penetrable growing medium.
Leave a little watering space below the rim. Label sowings or young plants so their species and dates remain identifiable during later care.
-
Water in gently
Water carefully with clean water suited to the crop. Direct a fine stream or rose so seedlings do not collapse and their roots are not washed bare.
Allow drainage and monitor moisture afterwards. A persistently wet surface is not the aim; suitable moisture depends on species, temperature and growth stage.
-
Monitor light, moisture and nutrients
After moving, protect from stressful direct sun if the species needs this, then provide enough light again. Watch new shoots, firm leaves and root development.
Follow the label by checking nutrients after about 4–6 weeks and supplement only if needed. Gradually accustom plants to a later outdoor position and account for species-specific frost sensitivity.
Continue care after moving
Match light and moisture
Germination temperature and light requirements follow the species and seed instructions. Once seedlings develop, provide enough light and recognise long, soft growth as a sign of unsuitable conditions. A warm windowsill is not necessarily bright enough.
Review nutrient needs
After about 4–6 weeks, check nutrients and begin supplementary feeding if needed. This label direction is a review point, not a requirement to feed automatically. Species, growth and nutrients already available remain decisive.
Move outdoors gradually
Introduce outdoor sun, wind and temperatures gradually. Frost sensitivity is species-specific. Neither winter dormancy nor one shared minimum temperature follows from the term propagation.
Notice small changes early
Check moisture, temperature, ventilation and light, and assess damaged plants separately. Various pathogens may be involved. Extra fertiliser is not a general solution; clean propagation containers and suitable moisture management help avoid unfavourable conditions.
Plan sowing and later care
Propagation spans many species without creating one shared flowering or care calendar. The guide covers the overall process; the particular species supplies the crop requirements.

What differs between the pack sizes?
The 2, 6 and 10 litre sizes each carry the same independently checked growing-medium declaration. Choose the quantity for your containers and number of sowings or young plants. Each pack has its own shipping weight and price.
Is this seed compost peat-free or sterile?
It is not peat-free: the label lists H2–H8 raised-bog peat. No general guarantee of sterility is given here. Use clean containers and suitable water, and store opened bags under cover.
Do I need to feed when sowing?
This mix already contains declared nutrients. An extra application is not automatically needed. The label calls for a nutrient check after about 4–6 weeks and further feeding if necessary. The particular crop remains decisive.
Can I sow directly into a garden bed with it?
The manufacturer limits use to soil-independent growing methods. The use described here therefore concerns trays, modules and pots. For direct sowing in garden soil, assess the soil and crop requirements separately.
Can I use it when pricking out seedlings?
The declared use covers plant propagation. Suitable young plants can be moved into this compost in a new module or pot. Choose timing, planting depth and later nutrition for the species; specialist crops may need another growing medium.
