Tree & Shrub Repotting Set

Repotting in eight steps

1. Recognise the need to repot

   Check whether roots fill the pot densely or the compost has lost its structure. Repotting should improve root space rather than simply follow an annual date. Plan substantial work in suitable weather towards the start of growth. Choose timing especially carefully for newly leafed Japanese maples or unhealthy plants.

2. Choose a pot for the root ball and growth

   A stable container needs room for the ball and some fresh compost. The plant’s shape and eventual size also influence the choice. The existing ball already occupies volume. Calculate new compost for the free space beside and beneath it, not automatically the entire pot volume.

3. Check drainage

   Inspect drainage holes and clear any blockage. A planting pot inside a closed decorative container needs its own open outlet. A coarse layer does not replace drainage holes. It must not obstruct the flow and is not necessary in every pot.

4. Release the old pot gently

   Support the weight at the root ball. Loosen the container by gently pressing or tapping it; do not pull the plant out by slender branches. Preserve healthy roots and remove loose old compost. Assess strongly circling or damaged roots separately; heavy root pruning is not an automatic repotting step.

5. Retain the original planting depth

   Add some compost and position the root ball. Keep its surface at the previous depth, with space for watering below the rim. Do not heap compost around the stem base or an existing graft union. Check that the plant sits upright and stable.

6. Fill around and firm lightly

   Add compost to gaps around the ball in small portions. Gentle pressure closes larger air spaces. Do not compact the compost hard. Watch planting depth, stability and even watering space around the rim.

7. Water the new root zone

   Water slowly and evenly so that the fresh compost beside the ball is moistened too. Observe drainage from the base. Match the quantity to existing moisture. Afterwards, remove standing water from the saucer or outer container; the pot should not remain in it.

8. Follow establishment and nutrient supply

   During the following weeks, check moisture in both the old ball and new compost. For Japanese maples, a suitable position and even moisture protect delicate foliage. Record the repotting date: after about four to six weeks, the label calls for nutrient checks and supplementary feeding if needed. Do not feed dormant plants simply by the calendar.

Prepare the fertiliser separately

10 ml per 2.5 l of water.

Every 2–3 weeks during the growing season.

April/May–September.

1. Shake

   Shake the concentrate before use.

2. Prepare water

   Pour the required amount of water into a suitable container.

3. Select strength

   Use standard 100%, young plants 50%, or seedlings with leaves 20% of the basic dilution. Concentration does not determine the watering volume needed.

4. Measure concentrate

   Measure the calculated amount accurately with a suitable measuring aid.

5. Mix

   Add the concentrate to the water and mix evenly.

6. Apply as needed

   Feed the already moist root ball when nutrients are needed; do not overwater using a rigid water volume.

Do not mix the entire bottle into the bag. The compost is ready to use; dilute the concentrate separately with water.

10 litres of compost: ingredients

Peat, perlite and raw clay with mineral fertiliser.

The original label lists 65% organic soil material from raised-bog peat H2–H5, perlite of natural origin, clay (raw clay), calcium carbonate and NPK(Mg) fertiliser.

Wetting agents aid water uptake. This product contains peat. The peat input percentage is distinct from the separately declared organic matter content.

Declared growing-medium values

Organic matter, pH, salt content and available nutrients.

Nutrient figures refer to the time the manufacturer places the product on the market. Levels may fluctuate or change in storage; check before using stored compost.

• Organic matter: 30%.
• pH (CaCl₂): 5.8.
• Salt content (KCl): 2.2 g/l.
• Nitrogen (N): 220 mg/l (CaCl₂).
• Phosphate (P₂O₅): 270 mg/l (CAL).
• Potassium oxide (K₂O): 400 mg/l (CAL).
• Magnesium (Mg): 70 mg/l (CaCl₂).
