COMPLANTATIONS or ROTATION
What is the complantation?
The
complantation, also called
racottage or
complantage, is to replace the dead walk by a plant without total uprooting of vines plot.
Complantation is not subject to declaration.
If the actual density is 20% lower than the minimum density provided by the Denomination of Origin
Controlled, the INAO (National Institute of Origin and Quality) can decrease proportionally
bumper yield. In addition, the wine syndicates may impose an intervention threshold of less than 20% or ask the INAO to decommission any parcel whose proportion of missing feet is too great.

Why complanter?
• To have a homogeneous vine, in accordance with the production conditions.
• To avoid losing a crop.
• To maintain competition between feet.
Which plant material to use?
• Plant certified material (blue label).
• Order the same variety as the original one.
• Adapt the rootstock according to the age of the plantation:
- rootstock identical to the rest of the plot in the case of replacement of plants in the first years after planting,
- rootstock more vigorous than that of the plot in the case of vine installed, to compensate for competition with neighboring adult feet.
When pulling the dead stump, extract the maximum of roots to protect against root rot and knotted bristles, so we chose to do this work with a mini-shovel instead than an auger.
For springtime plants, water abundantly when placing the plant and regularly until the fall.
To prefer the mixing to the layering. Phylloxera is still present in the vineyard and causes death of free-standing seedlings.
Extend plant protection against mildew down to harvest.
Several types of plants can be used:
• traditional sod transplant plant (GST),
• potted plant,
• container plant (superpot),
• large plant.
The choice of the type of plant is mainly a function of the period of completion.
Traditional soda graft plant:
Plant most commonly used, it was graftedin the spring of the previous year and put in nursery
to perform a complete vegetative cycle. The uprootingof the nursery takes place after the first frosts.
Optimal period ofcompletion: from Novemberto the end of April. From mid-December to mid-February, planting is only possible in well-drained soils, if the climate is favorable.
Observation: the longer the roots, thegreater the chances of successful completion.
important.
Plant in Pot:
The potted plant is a plant of the year. The cutting graftis planted in a biodegradable pot. Root formation is done in a greenhouse to accelerate growth.
Optimal period of completion: from Septemberto mid-December.
Observations: the potted plant requires aparticular manualplanting
For autumnal planting, the plant must beaugured.
Container plant(superpot):
The container plant is a plant in a loam ofcompost. The root system of this type of plant is already fully functional, hence a very good recovery capacity.
Optimal Period of Complantation: Productavailable for Fall and Fall Complantations
Spring.
Observations: The container may be ofdifferent volumes. It is not biodegradable. To avoid
winding the roots, scratching the mound beforeplanting.
Grand Plant:
It is a plant whose length of the rootstock is oversized(beyond 30 cm).
Its use avoids the setting up of weeding caches andsimplifies the establishment of the new plant. During the whole life of the vine, the trimming of the trunk is not necessary.
Optimal period of complantation: according to their method ofmanufacture (traditional, in pots or in containers), it is necessary to refer to the recommendations for the transplantation of transplant recipients
welded traditional, potted plants or superpots.
Observation: the plants should not be planted more than25 centimeters deep.
Warning on protective covers:
In the case of chemical weed control, it is essential to protect the plant with a cover. The latter is also very practical against rabbits that feed on young shoots.
However, it represents a vital danger in the case of excessive heat. It is then essential to remove it until the temperature drops.
The protective cover can also serve as a refuge for snails.
Finally, weeds sometimes grow in the cache without the winemaker noticing it.
Warning on weed killers:
Some weed killers have long remanence and should not be used the year before the planting and the following 3 years (phytotoxicity and mortality risks).
the complantation: a delicate operation
Complantation does not stop at planting the plant. For optimal success, it is essential to follow the plant renewal site until the end of the vegetative period (watering and phytosanitary treatments). Young plants require special attention.
