For nearly 40 years, Robin Nurseries has been multiplying developments and innovations for arboriculturists, foresters and other truffle growers. In the 1970s, ROBIN Nurseries developed its very first bucket to increase the quality of its young plants. Since then, the system has been perfected and developed to such an extent that the ROBIN ANTI-CHIGNON BUCKETS® are now patented and have become a registered trademark.

This constant will of research and innovation allows us today to propose, through these anti-sprouting buckets, a very efficient growing system, which guarantees a superior quality of the young plants.

A bucket to put an end to root bunting

Truffle growers as well as experienced gardeners know that the growth of a young plant freshly transplanted into the ground depends greatly on the quality of its root system. It is therefore better to avoid "bent" plants that will have difficulty regaining their vigor and developing properly and sustainably.

It is precisely to avoid this phenomenon of root bunting that Robin Nurseries has developed a range of cups specifically designed to guide the roots of young plants. These buckets have several singularities: vertical grooves directing the roots downwards, a perforated bottom preventing the roots from rolling up at the base of the container... All of these features are designed to prevent the formation of a circular root ball.

What is a root bun and why avoid it ?

Who hasn't had the experience of unpacking a plant and finding that its root system is a real tangle? A very dense agglomeration of roots rotating in the container, with a little bit of substrate mixed in: This is called a root bun. No doubt your plant has been in its pot for a long time and needs to be repotted!

A root bun is formed as a plant's roots grow. These roots accumulate, literally spin in the pot and eventually form a mass. The longer you wait, the greater the risk of root bunting, which compromises the plant's recovery!

Why? Simply because the roots of a plant memorize (in a way) their growth trajectories. So when they are transplanted in the ground, they will reproduce their root pattern and resume their growth in a "whirlwind" instead of extending and rooting deeply. Your plant will then vegetate, or even progressively wither.


Imagined and conceived in 1970, the Robin Nurseries' anti-sprouting bucket has since undergone several improvements and variations to best meet the specific needs of truffle growers and foresters. Whatever their destination, the objective remains the same for each of our anti-rotting buckets: to perfect the quality of our young plants in order to guarantee a recovery rate close to 100%!

Today, ROBIN ANTI-CHIGNON® BUCKETS are available in two forms: expanded polystyrene honeycomb blocks and individual square cups. The characteristics of these two models are summarized below.


Honeycomb block made of xxpanded polystyrene

The plants are delivered in their honeycombed culture trays. Designed in expanded polystyrene, these containers offer 2 different volumes of cells (200 or 400 cm3) and can receive between 43 and 74 plants each.

Robin anti-chignon® R200 bucket

- Container with 200 cm3 cells (74 plants per container)

Robin anti-chignon® R400 bucket

- Container with 250/400 cm3 cells (43/53 plants per container)

Robin anti-chignon® R430 bucket

- Volume of 0.43 liter - 45 plants per box.

Robin anti-chignon® R600 bucket

- Volume of 0.6 liter - 28 plants per box.

Robin anti-chignon® R1,5 bucket

- Volume of 1.5 liter - 15 plants per box.

Robin anti-chignon® R3 bucket

- Volume of 3 liters - 6 plants per box.

Please note that all our ROBIN TRUFFLE PLANTS and MUSHROOM PLANTS®, are grown in individual square Robin ANTI-CHIGNON® buckets and are available in the different volumes mentioned above.

Our ROBIN ANTI-CHIGNON® cups are environmentally friendly. They are systematically recovered by our trucks after planting and are reused up to 10 successive years. Therefore, we ask you to keep the empty containers at the end of your planting and to inform us so that one of our trucks can come and collect them as soon as possible.
