Description of the rose Iceberg
The award-winning Iceberg was introduced in 1968 and is still one of the most popular roses today. The rose itself is a strong shrub, dense and well branched, with smooth thin stems and glossy green foliage. The length of the shoots can be up to 4.5 meters.
This rose has almost no thorns. Cup-shaped, wide-opening flowers (5-7 cm) are collected in clusters (3-5 pieces) falling from the plant.
Flowers are produced continuously throughout the season – flowering period: from June to September. They bloom at the same time within a week, and last for about a month.
How to grow a climbing rose Iceberg?
Rose Iceberg gives abundant and frequent flowering, does not require constant care and is more resistant to diseases than other varieties. Spreading bush, can trail along the support. Best suited for hedges, in mass planting. Iceberg shrub should be placed close to a wall or other support, at a distance of at least 30 cm.
Additional Information! Unlike other roses, this variety tolerates direct sunlight well. In a shaded place, the number of flowers will decrease significantly. It is afraid of high humidity of air and soil, does not tolerate drafts.
These roses can be grown to decorate arches.
The soil
Prefers fertile, well-drained soils, but also tolerates clay and light soils. For optimal results, it is advisable to plant the Iceberg in slightly calcareous, well-drained soil, rich in organic matter and with a pH of 6.5. Clay soil can be balanced with sand and loam. In too sandy soil, you can add humus, compost, peat.
It is advisable to always put pebbles at the bottom of the planting pits. The depth of the planting holes is from 70 to 90 cm, the width is 70 cm. A distance of 150-200 cm must be observed between bushes of the same variety.
Watering
Rose Iceberg does not require a lot of water. Between March and September, it can be watered periodically. It has a well-developed branched root system that keeps water in the right place. During periods of severe drought, it is necessary to provide the rose with a sufficient amount of liquid. Irrigation should be normal, as for all roses. Water only when the soil seems too dry.
Note! Wet buds and leaves should be avoided. Excessive moisture can cause mold and mildew.
In autumn, watering is reduced and completely stopped with the onset of the winter season.
fertilizers
Roses need to be fertilized periodically to be able to grow continuously.
The first dose of fertilizer must be applied before planting, that is, during soil preparation. After the rooting of the Iceberg rose, it is necessary to fertilize twice between June and September. and once from September to mid-October. As with all roses, it is preferable to choose an organic fertilizer based on mature manure, perhaps combined with a granular fertilizer. It is good to put fertilizer at the base of the plant, regardless of whether manure or fertilizer in granules is chosen.
A lack of nitrogen and magnesium causes yellowing of the leaves and too small flowers. Chemical fertilizers take effect too quickly and lead to a weakening of the rose. Feeding should be introduced as gradually as possible: for this reason, slow release natural fertilizers are recommended.
Soil salinity – increased levels of water-soluble salts in the soil complicate flowering, so it is very important to control them. Soil salinization progresses with poor drainage. If the soil is too salty, the plant will wilt.
pruning
Rose Iceberg can not be cut. This rose is pruned only when absolutely necessary: in case of disease or damaged branches. If it is not cut, it can turn into a bush of decent height. In the period from February to March, a stronger pruning is carried out so that the bush acquires the desired shape,
It is advisable to make cuts at an angle of 45 degrees downwards: this avoids stagnant rain or dew, and strengthens the stems, which in the climbing variety must support the weight of flowers. Young pagons are thin and numerous, Buds grow on the branches of the year. Little old branches are left on the bush.
reproduction
Breeding can be by cuttings or seeds. The cuttings need a substrate consisting of peat and sand, which provides good water drainage, and enough softness for new roots.
Transplantation is carried out in spring and autumn. The best period is the beginning of autumn, the rose will have time to take root in a new place before the onset of winter.
Diseases and pests
Like all modern roses, it is fairly resistant to common diseases, making it easy to care for. Frost-resistant, can grow in regions where the temperature drops to -35 ° C.
The Iceberg rose is particularly hardy, however, it should be checked periodically to make sure it is not affected by diseases or pests. When buds appear, it’s good to check for aphids. At this stage, it can be removed with a jet of water or mild soap. After pruning branches, it is good to check if there are holes in the wood where pests can nest. If found, simply cut off the damaged part. In humid climates, it can be affected by black spot, powdery mildew and downy mildew. The presence of fungi often appears due to stagnant water. Requires removal of diseased parts and soil replacement, using appropriate fungicides.
Rose Iceberg is one of the most popular climbing roses due to its abundant flowering and unpretentiousness.
