Maintenance of gardens: a permanent struggle against the attacks of parasites.
Essential element of French gardens, the border of boxwood is ideal to mark the outline of a flower or a vegetable garden square.
A la Roche Courbon, we have almost 2000 meters of small boxwood, which have the advantage of slow growth and are cut 1 annually in April. Family Buxaceae, these shrubs can live several centuries
In recent years, new diseases are emerging on these species. This is the combined attack of two specific fungi boxwood.
Other gardens such as Versailles, Vaux le Viscount, Villandry suffer the same attacks, and thanks to the advice of their head gardeners, we began to change more than 900 feet to replace them with "sempervirens arborescens".
Sick feet were burned and the land was changed.
Instructions not spread cylindrocaldium buxicola (fungus that grows on the box):
(Synthesis symposium organized on the box at Vaux Vicomte lde March 4, 2015)
First demonstrations: black spots on the stems
Below 12 °: limit of the inoculum on the sempervirens.
Caution: automatic sprinkler irrigation is very bad (maintenance moisture).
DO NOT USE THE BLOWER, CLEAN CLOTHES, SHOES AND TOOLS AFTER SIZE SHRUBS.
The Tétroconazol is effective, but stress the plant by promoting Volutella buxi.
Smartphone: AGIIR: application of participatory science to fight against invasive insects (borers box).
General advice: wait 3 to 4 years that INRA is a suitable cultivar.
Do not rush ON NEW PURCHASES: PREFER grassed AREAS FOR RECALL OF BUIS ALIGNEMENTS.
DO NOT COUNT ON RELAXATION OF THE RULES ON THE USE OF PESTICIDES.
Good luck to all... !
