Where they put
Primrose planting and care(10 to 50 cm), so they are used for curbs, or planted in separate bright spots in the garden - under trees or among other later flowers. They prefer to grow in semi-shaded places on moderately moist soils.
Soil requirements
All primroses came down to us from the alpine mountain belt,therefore, the requirements for their habitat are appropriate. They need calcium (should be systematically make ash or lime, or even better - dolomite flour). In addition, they do not like too greasy soil (where there is, in the mountains, soil rich in humus!). Therefore, when landing in the ground, it is necessary to bring rotten compost in half with sand and with the addition of ash. On the clay they will not grow, as in the peat bog.
What to feed
Watering for primroses is especially important in the initialgrowth period in spring and until the end of flowering. Feeding required moderate. If primroses are too abundant to feed, then, like all flowers, they will “fatten”, that is, give a large mass of greenery and very few flowers. In the spring before flowering, calcium nitrate is most suitable (incomplete tablespoon per 10 liters of water), because it contains primula-favorite calcium and nitrogen, which is required for the growth of leaves. After flowering, for planting flower buds of the next year, one should feed with phosphorus and potassium (without chlorine) - half a tablespoon of each (or a tablespoon of the finished phosphorus-potassium fertilizer) per 10 liters of water. Primroses respond well to the introduction of any floral fertilizer, preferably not containing nitrogen. Spend both top dressing on 10 m² of landings. In the autumn, you need to pour some fresh compost under a primrose, literally a handful under a bush.
How to seat
Primroses belong to juveniles, not perennials, so they should be planted every autumn (or at least a year later). The best time for a transplant is August.
- The division of the bush. It is easiest to reproduce with young rosettes, carefully separating them with the roots. You can plant young plants right there, near the parent plant. But you can not tighten with a transplant, otherwise the outlet will not have time to properly take root and die at the first freeze.
- Seeds. Since the seeds are very small, they must be sown superficially or sown on snow in late February - early March. There is a small nuance here. After sowing, the plates with seedlings should be put in a refrigerator for several days and only after that put in a warm room, but not in direct sun. After the emergence of shoots, place the bowls in a bag, breathe air several times into it, tie and put it into the light. It is necessary to water from the syringe through a needle stuck into the soil. When the seedlings grow, they should be carefully picked up in separate boxes or jars and grown to a bush with 5-6 true leaves, and then transplanted after frost, first to grow and only in August - to a permanent place. Primroses grow quite quickly, so provide them with a place for this (20 to 20 cm). Primroses do not have pests and special diseases, so the plants do not require special care or care.
Sometimes primroses try to bloom again - warm.in the fall. This should not be allowed. It is necessary to pluck the buds as soon as they appear, otherwise the plants may weaken and miss the spring flowering next year.
Timing of flowering
Late April - early May Primrose springbloom the very first. From the rosette of wrinkled basal leaves, a bare peduncle with a height of 10-30 cm rises with a loose umbrella inflorescence at the top. In nature, the flowers of this plant are yellow, with a diameter of 1.5 cm. But there are many hybrid garden forms, including terry ones, of the most diverse colors. Primrose blooms around the same time as it blooms. This is a stemless primrose. The flowers she sits on one at the ends of short, undeveloped peduncles. But they are usually many, so they form a colorful pillow, 10-12 cm tall. The flowers are quite large (2-3 cm in diameter) of various colors, often yellow of all shades, crimson with a yellow eye. The most popular varieties of Virginia with white flowers and Cerulea - with blue. The primrose is also very early in bloom, with several flowers on its peduncles (20 cm high). When crossing this species with primroses of ordinary and stalkless, many beautiful hybrids were obtained, among which the white Alba, the golden Aurea, the crimson Gartenprimel, the velvet-brown Goldrand, and others are the most popular. The primrose was a high-flowering primrose with a multi-flower with large buds of 15-20 flowers on a high peduncle (40 cm). In the middle of May, one of the most beautiful primroses blooms in mid-May - a finely toothed primula. It got its name from the jagged edges of the leaves, from the outlet of which on high peduncles (30-40 cm at the beginning of flowering and 50-60 cm after the end) are spherical inflorescences consisting of many small flowers of the most varied color (from white and pink to lilac of varying intensity and crimson). At the same time it blooms and is low, only 10-12 cm tall, the primula of Julia with crimson flowers. There is a hybrid with white flowers, but the most beautiful is the mixture with the romantic name Romeo and Juliet with pink and blue flowers. At the time of flowering, the primrose of Julia forms solid mats and is very good on the alpine slide. By the way, it is the most frost-resistant and unpretentious of primroses. A little later primrose uskovka with unusual dense, smooth leaves of a bluish-green color, which are a little wrapped, like the ears of some unknown animal. Flowers 3-4 cm in diameter are collected in umbrellas of 5-15 pieces. They have an unusual round shape with festoons and a two-tone pale color of violet-lilac tones of different shades. There is a very interesting hybrid of this primrose - the primrose is pubescent. End of May At the very end of May, Siebold's Japanese primrose blooms - a small plant with light green leaves and pale pink flowers with a white asterisk in the middle, gathered in a loose umbrella. She has one feature. After flowering, the above-ground part of it disappears, and therefore, in order not to damage or sleep the plant, you should mark the places of its planting. June - July In June and July, primrose groups Kandelyabrovye are rare in our gardens, they come from Japan. On high peduncles (50 cm) in several tiers inflorescences of bright purple flowers are located. Begin to bloom from the lower tiers. There are garden forms with flowers of white, pink, lilac, cherry flowers. Candelabra primroses include Bis primrose with violet-purple flowers and Bull primula with creamy yellow and orange flowers, as well as their hybrid Bullesian primrose with very beautiful coral flowers. This rare primrose blooms from late July to mid-August. From the rosette of beautiful large leaves grows a long peduncle (70-80 cm), topped with a very bright orange brush of bell-shaped fragrant flowers. This plant looks great near the pond.
