An exotic guest does not need an abundance of sunlight; she spreads a carpet of carved leaves in shady corners where other plants wither away without bright rays. Consider how to grow Rogersia - choosing a place, planting and care, as well as use in landscape design and plant propagation methods.

Description and features

The homeland of Rogersia (Rodgersia) is the eastern part of Asia, the Himalayas. It is a herbaceous perennial with a long taproot. The plant is cultivated because of the beautiful carved leaves - on long petioles, pinnatiform or palmate, with a pointed end.During the growing season, the foliage may change color. Inflorescence - panicle, color of small flowers - from white to red. Bush blooms 4-6 weeks in mid-summer. Bright flowers against the backdrop of a carpet of foliage look elegant and touching. Belongs to the Saxifrage family.

Choosing a seat

The selection of a place for landing Rogersia should be taken seriously - the bush lives for a long time, it does not require a transplant. What to consider when choosing a place:

bush grows better and looks better in shading conditions;
the plant has a powerful root system, which is constantly growing, can destroy neighboring plants with a weaker root;
shrubs grow up to 1-1.2 meters in diameter, sufficient space must be provided;
In low-lying areas with high groundwater and frequent puddles, Rogersia root can rot.

Different varieties are advised to plant at a distance from each other, as Rogers can be pollinated. Bushes are planted in places illuminated by scattered rays of the sun 1-3 hours a day - between the fence and buildings, between bushes and trees.

Soil Requirements

Rogersia requires a light, air-permeable and moisture-permeable soil with neutral acidity. Heavy clay soils facilitate tree foliage, compost, humus. The site for planting is dug up in advance, if necessary, deoxidized with lime, and complex fertilizers are applied.

Timing

Rogersia takes root well after planting in spring and autumn. Things to remember when choosing a date:

Experienced flower growers believe that Rogersia planted in autumn quickly grows in spring. It is important not to plant the bush too late so that the root system has time to get stronger before frost.
When planting in the spring, you need to wait for a steady heat - 5-10 ° at night during the week.

Rogersia is often planted out of pots along with the soil, so the plant takes root quickly and without problems.

Plant pattern

Shrubs are planted at a distance of 1.2-1.5 meters, trying to place different varieties away from each other. The pit is prepared in advance, focusing on the size of the seedling:

the bottom is lined with a drainage layer - broken brick, small stones, sand;
preparing planting soil - a mixture of compost, humus, foliage, fertile soil, pour a small layer on the drainage;
remove the plant from the pot along with the earthy clod or straighten the roots of an open seedling;
placed in a hole, deepening 6-10 centimeters, covered with soil, lightly rammed, watered.

To retain moisture, the soil in the root hole is mulched with organic matter - foliage, hay, dry grass.

Care

Shaded Rogersia effectively changes the color of the leaves, looks fresh, gives tall peduncles with a large number of fragrant buds. In order for the bush to grow quickly, you need to adhere to the rules of care recommended for the culture.

Irrigation

The exotic perennial loves moisture, but the overgrown rhizome does not tolerate stagnant water. When choosing an irrigation regime, they are guided by the weather features of the season. In dry times, water 2 times a week. If the weather is rainy, check the soil moisture and adjust the Rogersia watering pattern.

Especially carefully water bushes growing along water bodies and receiving moisture from the soil. With an excess of water, vegetation slows down due to root rot.

Reference: the powerful Rogersia root is often exposed during watering, you should immediately cover it with a layer of fertile soil and organic mulch to protect it from drying out and damage.

Cutting

Decorative pruning is not required for bushes. Flower growers advise immediately cutting out drying and fading leaves so that they do not spoil the appearance of the plant, and in the presence of diseases or pests do not infect the entire bush. If seeds are not needed, drying flower stalks are cut off immediately after withering, so that they do not stick out with dry sticks above the greens. If it is necessary to obtain seed material, only 1-2 peduncles are left.

Feeding

In spring and autumn, the bushes are fertilized with organic matter, in the absence of nitrogen fertilizers are applied to ensure the growth of green mass. Manure or bird droppings are infused in water for 10-14 days, then diluted with water and fed to the bush during watering. Rogersia needs complex top dressing containing sulfur, iron, magnesium, zinc, which will ensure flowering.You can use organomineral fertilizers for flowering plants, also containing potassium and phosphorus. 2-3 feedings are carried out during the season.

Mulching

Mulch serves to retain moisture at the roots, reducing the need for watering. The root circle of Rogersia is mulched with organic matter (hay, sunflower husks), which will later become fertilizer.

Reference: a thick layer of mulch is used to protect the rhizomes from freezing in winter.

Preparing for winter

Most varieties of Rogers are famous for their enviable frost resistance. To reliably save the plant from freezing, you must:

Before the start of frost, cut off the green part under the root. This will facilitate wintering in any region.
Water the bush thoroughly. Pour in 1-3 buckets of water, depending on soil moisture.
Cover the soil around the bush with a thick layer of mulch.
In cold regions (Siberia, northern regions, Urals) use additional insulation.

With the advent of spring, the covering material is removed to prevent decay and decay of the roots, to ensure natural ventilation and drying of the soil. Old mulch is removed or dug up and turned into fertilizer.

Diseases and pests

In a rainy year and in lowland areas, Rogersia suffers from fungal diseases. Despite the resistance of the culture to diseases and pests, with an excess of moisture, a rust fungus, snails and slugs can appear on the bushes, choosing plants in shady places.

Rot can be identified by yellowing and dying leaves, dark spots, slow growth. A bush affected by root rot is dug up, diseased areas of the rhizome are cut out without pity, treated with fungicides, and transplanted.Pests are fought with mechanical, folk (dry mustard) methods or chemical preparations ("Thunderstorm").

Reproduction

Rogersia breeds in all traditional ways. Most flower growers prefer vegetative ones, since seed propagation will take a long time to wait for the result, varietal properties are not transferred.

Dividing the bush

Dig up a part of a horizontally located root from the soil. Divide it into parts (about 10 centimeters) with 2-3 kidneys. In the spring, pieces of the root can be planted in the soil; in the fall, delenki are planted in containers and grown at home. Plants are provided with regular watering and fertilizing.

Shanks

The role of the cutting in the reproduction of Rogersia is performed by a leaf with a petiole. It is cut off, placed for several hours in an aqueous solution of a root formation stimulator. Then transferred to a nutrient substrate until strong roots appear. Maintain soil moisture, temperature 15-18 °.

Seeds

Before planting, the seeds are hardened - wrapped in a damp cloth, kept in the refrigerator for 2 weeks. Planting time is the end of February. Hardened seeds are sown in nutritious soil, carefully placed on the surface of the soil. Lightly powder with dry soil, moisten with a spray bottle. The container is closed with glass, humidity and constant temperature (18-20 °) are maintained. Feed after germination. When several leaves appear, they are transplanted into individual containers for growing.

Landscape use

With the help of Rogersia, you can plant shaded areas, giving the garden an exotic flavor and charm. A change in the color of the leaves noticeably changes the appearance of the bushes, the flowers, although they are not very decorative, adorn the plants for 4-6 weeks. Rogers are planted next to bluebells, delphiniums, and ferns.Delicate irises, daffodils win next to the abundant greenery of the bushes. Powerful foliage looks great against the background of coniferous trees, juniper. Rogers decorate rockeries, complex flower beds, rocky gardens. It is believed that the bush is in harmony with most plants, but it is also used for solitary plantings alone.

Why does not bloom and grow

Rogersia needs fertile soil rich in trace elements - zinc, phosphorus, copper, sulfur. Let's note some care nuances:

Green mass does not grow well with a lack of nitrogen in the soil. Rogersia weakly grows foliage, the bush does not increase in size. It is required to apply nitrogen fertilizers to the soil.
With a lack of nutrients, flower buds are not laid, the peduncle is not formed or is weakened. Excess nitrogen fertilizer leads to excessive growth of greenery at the expense of flowering. To stimulate flowering, Rogersia should be fertilized in May-June with potash and phosphate fertilizers, growth regulators.

Negatively affect the formation of flower buds lack of moisture, irregular watering. If Rogersia constantly receives less moisture, the leaves fall off, do not grow to the usual varietal size, flower stalks are not laid.

Rogersia has an unpretentious disposition, the bush grows in one place up to 10 years. Large bushes with carved leaves that change color, steadfastly tolerate shading. Rogersias are grown in areas with a large number of trees, in corners where sun-loving flowers cannot survive. The exquisite perennial is gradually winning the hearts of Russian flower growers.
