Culture of the rose trees

The culture of the rose trees is practiced is in a professional framework: nursery gardeners Rosiériste S, managers of public green areas, is within a deprived framework, the gardens of private individuals are seldom without Rosier S.

This activity can aim at the production of flowers cut for the sector of the fleuristery or of seedlings of rose trees generally sold by the die of the Jardinerie S or large surfaces, or the ornamentation of the private public gardens or .

Multiplication

The multiplication can be carried out by Greffage, suckering, Bouturage, sowing and multiplication in-vitro. Almost the totality of the rose trees come specialized nursery gardeners.

The understocks are ecotype S of Rosa canina and rosa rubiginosa which has the disadvantage of suckering much, or rosa indica major which suckers little and rosa coriifolia " frœbelii" who does not sucker.

Plantation

The plantation is carried out in autumn and winter (from November to March in the northern hemisphere), in a quite battered ground then rested, in a sufficient cavity so that the roots are at ease and the point of Clerc's Office (or the collet for the not grafted rose trees) very slightly buried. A watering ensures the compressing of the ground.

These rose trees must then be sprinkled regularly the first year and the foot mulched to protect them from the cold in winter.

Cut

In addition to the size of the faded flowers, it is necessary to carry out an annual size, towards at the end of February for the tonics, after the flowering for the others, which will vary according to the species, the age and the state of the rose tree. It is especially necessary to remove old wood and to cut all the more short as it is about a small species, and to leave size to climbing which if not could become again bushes.

Treatments

The white of the rose tree is treated by a pulverization of Soufre and the black spots of Mildiou by a pulverization of Bouillie of Bordeaux (one can in certain forms mix both in preventive medication).

The Puceron S will be eaten by the ladybird S or will be driven out by a watering. The more particular problems concern the council of specialist.

Fertilization

Rock salt, manure “special rose tree” or ashes of wood.
