Where and how it grows

The panicle saxifrage has an amazing feature - to break through to the light on lifeless areas of the earth's surface with a predominance of natural stone. Developed rhizomes easily take root on mountain slopes, penetrate rocky cracks, grow widely in narrow gorges, on limestone slopes, granite ledges, rocky soil. Rip-grass is not afraid of drought and wind. It destroys even stone barriers, forms dense and dense clumps. The root system and leaf rosettes of the paniculate saxifrage grow in different directions and form the original dense, hemispherical turf.

The plant blooms in May-June. Loose panicle-shaped umbrellas are formed until July-August, after which the rosette with a flower shoot dies off. The decorative appearance is appreciated not only by the flourishing culture. Very beautiful miniature leaves, collected in original basal rosettes, reminiscent of exotic multi-layered flowers. New leafy "stars" are formed from the mother's - on long stolons.

As a result of anthropogenic human activity, some varieties and species of saxifrage are included in the Red Book of Russia and are protected by the state.

Planting and leaving

All representatives of the Kamnelomkov family do not differ in the complexity of planting and care. Hardy and frost-hardy rift-grass grows best in areas similar to their natural habitat. Decorative varieties are propagated in several ways:

  • seed;
  • vegetative (division of the mother bush, cuttings).

Most often, the separation of the rosettes of the paniculate saxifrage is used together with a part of the rhizome

Recommended timing

The best time to transplant a tenacious saxifrage is the middle of the summer season. Young rosettes can be detached and replanted in early spring. Plots must contain viable root suckers. Mother plants are separated at least once every 4-5 years, since the rosettes begin to thin out, lose their decorative appeal. The culture is not transplanted during flowering.

For seedlings, the seeds of a paniculate tenacious saxifrage are planted in March-April in planting boxes with treated soil mixture.

Numerous, smallest seeds of saxifrage ever-living paniculata fall into the soil by self-sowing, stratify in winter, sprout in spring

Site selection and preparation

Most landscape designers and gardeners prefer to decorate original rockeries, rock gardens, retaining walls with original ground covers. The most suitable place is the northern or eastern slope, slightly shaded areas of the garden. The following requirements are imposed on the soil:

  • slightly acidic, neutral, loose, light, granular soil;
  • sufficient level of drainage layer;
  • the presence of lime chips, coarse sand, vermiculite, clay;
  • high content of humus, humus, black peat, calcium.

The ever-living saxifrage looks original and aesthetically pleasing in picturesque crevices, between stones of various sizes

Landing algorithm

The planting holes are shallow enough to accommodate the plots. Parts of basal rosettes with small roots are placed in the ground, pressed down and thoroughly moistened.

During seed propagation, the planting material is embedded in seedlings without deepening. The smallest seeds are mixed with fine sand, spread over the surface of the soil and sprinkled with sifted earth a little. Saplings appear in 2-3 weeks. For the growth and development of seedlings, a sufficient level of humidity must be maintained. Seedlings are distinguished by a long period of development. Cotyledonous leaves are formed only one month after germination.

The distance between plants should be at least 10 cm, since the saxifrage grows quickly and takes up free space

Watering and feeding schedule

The plant needs gentle, neat, but frequent watering. In addition to moisture, the soil should be periodically loosened around the root rosettes.

Fertilize saxifrage with superphosphate, as well as organic compounds with a large amount of bone meal.

Areas with planted saxifrage ever-living paniculata will look neat and well-groomed if faded inflorescences are removed in a timely manner

Preparing for winter

A characteristic feature of paniculate saxifrage is frost resistance. It is not for nothing that culture is called everlasting. The plant does not require mandatory winter preparation.

In snowless winters, you can cover ever-living rosettes with sawdust or dry branches.

Diseases and pests

Stress-resistant saxifrage, ever-living paniculata, is distinguished by persistent immunity. In rare cases, the plant can be attacked by ants. When large colonies of insects appear, the saxifrage rosettes can be treated with modern insecticides. The most effective are universal aphid remedies.

Plants should not be treated with aerosol preparations, since the settling composition spoils the decorative appearance of the leaf rosettes.

Sometimes the leaves may show rust or wet rot in the central part of the plants. The cause of the appearance of the fungus is insufficient drainage and lack of ventilation of the outlets.

Spores of rust pathogens infect leaf blades and appear as red-violet spots. Gradually, the foci grow, the leaves are deformed, dry out, since the process of photosynthesis is disrupted. The plant loses nutrients and dies.

For the early fight against rust on the bushes of the ever-living paniculate saxifrage, modern biological and chemical preparations are used (Bordeaux mixture, Abigapik, Topaz, Hom)

Wet bacterial rot attacks healthy rosettes. The pulp of the leaves softens, covered with a layer of mucus. The infection spreads quickly to other plants. The affected bushes should be removed and burned, the ground should be disinfected.

For the prevention of wet bacterial rot, autumn soil treatment with bleach, formalin, chloropicrin is used

Conclusion

Saxifrage paniculata is a beautiful perennial ground cover, which is distinguished by unpretentiousness, frost resistance, rapid growth and excellent decorative qualities. The exotic shape of the flower-shaped leaf rosettes maintains elegance all year round. The plant is characterized by a number of medicinal properties. In folk medicine, roots and leaves are used. Natural raw materials are used for the preparation of drugs for diseases of the genitourinary, cardiovascular system, gastrointestinal tract.
