Cultivation of climbing roses
Roses love sunny places sheltered from cold winds.
They prefer fertile, calcareous, medium-textured and well-drained soils. The ideal soils are slightly acidic ones with an ideal pH of 6.5 / 7 but also adapt to alkaline soils.
In spring and in dry periods, wet the soil regularly to favor the opening of the leaves and the swelling of the buds. During watering, avoid wetting the leaves and flowers.
From March onwards, fertilize bush roses and climbing roses every 20/30 days with specific fertilizers for roses rich in phosphorus (P) and potassium (K). The fertilizer in granular form must be buried at the foot of the plants at a depth of about 15 cm. The recommended dose is 20-30 g per plant. After fertilization, water abundantly.

Climbing roses: growing in pots
The climbing roses grown in pots represent an interesting choice among the plants used to embellish the terrace of the house with a cascade of green, color and perfume.
In this type of planting, the rose uses the iron railing of the terrace of the house as a support to develop and it is good to choose a pot of at least 50 cm in diameter to allow one growth free of explants until the plant is equipped with a sapling stem.
It is necessary to ensure the right drainage to avoid root rot, using where possible terracotta pots in place of the plastic ones or remedying with a bottom of about 7 centimeters composed of expanded clay or earthenware shards. The pot should be filled with quality soil at pH 5.5 – 6 composed of about three parts of coarse and fibrous blond peat and one part of clay and an adequate dose of slow release organic fertilizer. The specific granular fertilizer for rosaceae must then be administered at least twice a year. A first fertilization is carried out at the end of winter (March – April) and the second between August and September. As for the care of climbing roses in pots, these do not differ from those for roses grown in the ground.

After planting, water and lightly mulch with compost or coniferous bark if the danger of frost is not yet averted.
Topping the roses
To favor the development of lateral buds and new shoots, top off the apical parts of stems below the first leaf composed of 5 leaflets.
Pruning of climbing roses
Pruning of roses is usually done in month of February. In March if dry or damaged branches need to be pruned.
Climbing roses should be pruned leaving 3-4 basal stems distributed in a fan shape. The lateral branches should be cut up to 10 cm in length.
