GREEN24 · Substrate knowledge
Repot cacti to suit their species and roots
Handle spines safely, protect roots and plan the first watering carefully.

Release the ball safely
Use a soft handling aid when unpotting. Support the ball and do not pull on spines or thin segments.

Root condition guides watering
Preserve healthy roots. Do not immediately soak freshly damaged roots; consider species and temperature.

Respect spines and growth form
Globes, columns and segments need different support. A group name does not replace species-specific care.

A closer look at the compost
The original image shows organic material and mineral grains in the mix. The label lists peat, rock, raw clay and sand; this is not a purely mineral growing medium.
Practical guide
Planting and repotting in eight steps
Match the pot and medium to the species; the sequence shows the main handling steps.
- 1
Assess need and species
Repot when the root ball needs more space or the medium has lost structure. Check the species and resting period.
- 2
Choose a suitable pot
Choose a pot only moderately larger with unobstructed drainage holes. An oversized pot can remain wet unnecessarily long.
- 3
Keep drainage clear
Keep drainage holes clear; use a permeable cover against compost loss if needed. A thick gravel layer is not a general requirement and cannot replace a free outlet.
- 4
Release the root ball safely
Use suitable gloves and a soft handling aid. Release the root ball without pulling on spines or thin segments.
- 5
Check roots and planting depth
Preserve healthy roots where possible. Position the plant so its stem base and root collar sit no deeper than before.
- 6
Fill gently around the sides
Add medium around the sides in small portions and let it settle gently. Avoid hard compaction and leave a small watering space.
- 7
Allow for root recovery
Do not immediately soak freshly damaged cactus roots. Match the first watering to species, temperature and root condition.
- 8
Observe aftercare and growth
Place the plant in shelter initially and acclimatise gradually to stronger light. The compost label specifies feeding after 4–6 weeks, when growth and roots are ready.

Which cacti is PRO Humus suitable for?
It suits cacti and succulents that require some humus. Check your species’ needs: if it requires a purely mineral medium, choose a suitable mineral mix.
Is this cactus compost peat-free?
No. The current label lists raised-bog peat along with rock, raw clay and sand. For peat-free cultivation, choose a growing medium explicitly labelled peat-free.
Should I choose 2.5 or 5 litres?
Allow for the spaces around and beneath the existing root balls. Both packs have the same declared composition; the quantity you need depends on your pots and number of plants.
Does a cactus need repotting every year?
Base the decision on root space and the condition of the growing medium. Repot when the root ball needs more room or the compost has lost its structure, taking your species’ resting period into account.
Is a much larger pot a better choice?
When more space is needed, choose a pot only moderately larger, with clear drainage holes. An oversized container can remain wet unnecessarily long.
Should I water heavily straight after repotting?
Do not immediately soak freshly damaged cactus roots. Adjust the timing and amount of the first watering to the species, temperature and root condition.
Should I add cactus fertiliser when repotting?
PRO Humus is ready to use and already pre-fertilised. The label specifies further feeding after 4–6 weeks; use a suitable fertiliser when growth and root condition are ready.

Safety instructions
Follow the label on the bag.
- Use suitable gloves and a soft handling aid when repotting. Spines and fine bristles can cause injury; do not grip with bare hands.
- Avoid dust and ventilate well when transferring the mix. Use a suitable mask when needed, particularly with respiratory conditions or allergies to mould or growing-medium ingredients.
- Avoid eye contact; rinse with water if contact occurs. Wash hands thoroughly with soap and water after use.
- Do not eat the compost. Keep away from children, pets, food and animal feed. If accidentally swallowed, seek medical advice and have the product information available.
- Growing media may contain microorganisms. Protect open wounds; clean and cover injuries.
- Keep bags closed during transport. Clear up spilled compost promptly to prevent slipping.
