Hybrid tea rose “Red Intuition”

Hybrid tea rose “Red Intuition” ('Red Intuition' Rose) - a hybrid tea rose cultivar. It was first introduced in France in 1999 by the Delbard company. Introduced in 2004 in France. It received the awards “Best Hybrid Tea Rose” at the Scottsdale Rose Society Show, “Most Decorative Hybrid Tea Rose” at the Kern County Rose Society Show and “Best-blooming Hybrid Tea Rose” at the Albuquerque Rose Society Show in 2005.

It forms a tall, lush shrub 100-120 cm in height and up to 70 cm in width, practically without thorns. Leaves are decorative, semi-glossy, leathery.

Buds are high, classic goblet-shaped, solitary or up to 5 per stem. Flowers are large, up to 12 cm in diameter, double, scarlet with dark burgundy velvety streaks and variegations, up to 45 petals. Blooms continuously, practically the whole season. Fragrance light, almost imperceptible.

Hardiness zone: 7b (-12°C)

Location: choose a sunny, bright site sheltered from strong and cold winds.

Soil: the most suitable soils for roses are heavy loamy soils rich in humus, well-aerated, moisture-retentive, slightly acidic (pH 5.8-6.5). Soil for them is prepared in autumn or at least one month before spring planting. It is very important to cultivate the soil to a depth of 50-60 cm. Per 1 m2 of cultivated layer, apply 10-20 g of manure, humus or peat compost, 300-400 g of lime, 400-500 g of bone meal, 40-50 g of superphosphate, 150-200 g of wood ash. The soil is dug and mixed with the fertilizers, with organic matter in the soil mixture not exceeding 50%. Exact fertilizer rates are calculated based on soil analysis. The optimal content of main nutrients for the rose should be maintained in the following ratios, mg per 100 g of soil: nitrogen - 10-20 (NH4NO3), phosphorus (P2O5) - 60-80, potassium (K2) - 80-100, calcium (CaO) - 720.

Planting: recommended to perform in the first half of the day. In the temperate zone it is best to plant roses in spring - late April - early May, in the south - in autumn. Before planting remove all damaged and diseased shoots and roots from the seedling. Strong shoots are cut short to 10-15 cm, leaving only 2-4 buds on them. Roots are trimmed slightly to live tissue. If the roses were dried, they should be placed in water for 24 hours before planting, and immediately before planting dip the roots into a manure-clay slurry. Planting holes are prepared 50x50 cm and filled with a nutrient mixture: 1 part turf-clay or garden soil, 1 part humus or compost - so that a mound is formed. Place the seedling on the mound, spread the roots and cover with soil, compacting it thoroughly so there are no air pockets between roots and soil, and water abundantly. The graft union is buried in the soil by 3-5 cm. After watering the roses are mounded. Protect shoots from drying. After shoots appear, rake the soil and mulch with humus or peat to a layer of 5-8 cm, which helps retain moisture. Spacing in a row between hybrid tea, floribunda and polyantha roses is 25-30 cm, between rows 60-70 cm; for shrub and climbing roses respectively 45-50 and 80-100 cm; miniature roses 15-20 and 40-50 cm. When planting standard (grafted-on-stem) roses to prevent drying, their grafted part is often packed with moss and tied with paper, which is removed only after 1-1.5 weeks when buds begin to break. After planting, mulch the soil with peat or soil to a layer of 3-5 cm. When planting non-remontant park roses, mulch the soil with pine bark or wood chips.

Care: requires regular pruning of shoots affected by pests and diseases, as well as removal of dead leaves. Watering is recommended during dry periods.

Pruning: carried out in spring, summer and autumn. The main pruning is done in spring, when the bush is formed. It begins immediately after the final awakening of the plants after winter or when planted in spring. The tops of shoots are cut regardless of variety; strong shoots are shortened to 10-15 cm, leaving 2-3 well-formed buds, weak ones 1-2 buds. With autumn planting, pruning is done in spring, immediately after removing the cover.

Propagation: mainly by grafting and cuttings. Cuttings are prepared during budding or immediately after the first flowering. Shoots are cut from the bush and cuttings 5-8 cm long with 2-3 leaves are prepared from the central part. The lower cut is made under the bud at an angle, and the upper cut 1 cm above the bud. To reduce transpiration, the lower leaf and part of the upper are removed. Leaves must be handled carefully; they should not be completely removed, as cuttings will not root without them. Before planting, cuttings are placed in a rooting stimulator for 18-20 hours, immersing the ends 1-1.5 cm. This can be a 0.01% solution of heteroauxin. You can also use Kornevin, sodium humate (1 tablet per 1 l of water), aloe (10 drops per glass of water) or honey (1 teaspoon per glass of water). Then the cuttings are rinsed with clean water and planted. Cuttings are planted in a box or bed. The bed should be located where morning or evening sun reaches it, and it is shaded during midday sun. As substrate usually use coarse river sand, a mixture of vermiculite with sand or sand with peat (1:1). This substrate in a layer of 3-4 cm is placed over turf-humus soil (8-10 cm). Cuttings are planted at an angle, buried 1.5-2 cm. Afterwards they are covered on the bed with glass or plastic jars, and the box is covered with film. After planting, moisten the cuttings several times a day, preferably with a sprayer, maintaining humidity at 80-90%. Remove fallen leaves. After 2-3 weeks a callus appears on the cuttings, and roots form after about a month. Remove jars or film, and grow on the cuttings, feeding every 2 weeks with a solution of ammonium nitrate or urea (15-20 g per bucket of water).

Diseases: high resistance to diseases.

Pests: aphids, scale insects, leaf-rollers, rose sawfly, thrips, rose cicadas, inchworm caterpillars, cutworms, spider mites, nematodes. It is recommended to regularly spray hybrid tea roses with specific products for pest protection.

Use: looks spectacular in mixed borders, as solitary plantings, and in the front of bedding compositions. Suitable for cutting.
