Product Information

Full details

The Haxnicks Maxi Rootrainer is designed for gardeners and plant enthusiasts focused on propagating larger specimens such as shrubs, hedges, and broadleaved trees. Its primary benefit is the innovative air-pruning technology that prevents root-binding and fosters a dense, fibrous root system, though users should note that the system requires more careful monitoring of moisture levels compared to solid-walled plastic pots.

FAQs

Can I use these for vegetables?

Yes, they are excellent for larger vegetables like runner beans or sweet peas that benefit from deep root systems.

How many cells are in a full set?

The system includes 10 'books', each containing 4 cells, for a total of 40 propagation cells.

Do I need special soil?

A standard, high-quality multi-purpose or seed-starting compost works best.

Are the root trainers BPA-free?

The materials are food-safe and durable, though intended primarily for horticultural use.

How often should I water?

Check daily; because of the aeration features, the soil may dry out faster than in standard plastic trays.

Can I leave these outdoors?

Yes, they are weather-resistant, but they should be kept in a sheltered area to prevent the small volume of soil from freezing or drying out too quickly.

Troubleshooting

Growing medium falling out of the bottom

Ensure the bottom drainage holes are not overly large and use a slightly coarser compost mix if necessary.

Cells opening prematurely

Check that the locking mechanism on the 'book' is fully snapped into place and that no debris is stuck in the hinge.

Pros and Cons

Pros

  • Prevents spiral rooting and root-bound plants
  • Minimizes transplant shock during potting out
  • Easy inspection of root health without disturbing the plant
  • Space-efficient design compared to individual pots
  • Reusable for multiple seasons

Cons

  • Cells can dry out faster than traditional pots
  • Requires proper assembly to ensure cells close securely
  • Higher initial investment than basic plastic seed trays

Setup, Compatibility & Care

To set up your Maxi Rootrainers, ensure the cells are snapped securely into the tray frame, ensuring the 'book' hinges are aligned and closed tight. When filling with compost, tap the tray gently to settle the medium without compressing it too hard, which allows roots to penetrate the soil easily.

Care Instructions:

  • Cleaning: After each use, wash with warm, soapy water and a soft brush to remove residual organic matter.
  • Storage: Store in a cool, dry place away from direct sunlight to prevent plastic degradation.
  • Handling: When transplanting, open the 'book' fully to allow the root plug to slide out gently rather than pulling the plant by the stem.
