Irises: when to transplant and in what ways?
Almost every sign of the iris is a flower that has become widespread throughout the planet and is most abundant in South-Western and Central Asia, as well as in the Mediterranean countries. One of the nebulae of the constellation Cepheus was named after him. Its appearance resembles this unusual creation of nature.Characterized by dense, erect leaves and bright large flowers of bizarre iris, whose name in Greek means “rainbow”, has about 800 varieties. In Russia, this elegant flower, which is the attraction of almost every garden, is affectionately called "iris". The plant is perennial, has branching creeping rhizomes or bulbous roots.
Iris blossom is a festive, elegant, multi-shading spectacle, uplifting and inspiring to breed new varieties on its own plot.Iris breeding is performed by two methods: seed and vegetative - the most common among gardeners because of their simplicity. The seed method is mainly used in plant hybridization. The first flowering with this method is observed after 2-3 years from the time of planting. The use of the vegetative method, for which both wild-growing and varietal specimens are suitable, makes it possible to obtain blooming irises in the first planting year.When to replant these plants to get plenty of flowering bushes throughout the season?
The procedure for dividing the bush iris
For division, you need to choose a well-developed, powerful bush that you need to shake off the ground, while saving it from sick, dry leaves and rotten roots. The rhizome should be broken down in such a way that each part remains with a fan leaf bundle, which needs to be shortened by half, and the roots - by a third. The material prepared for planting is recommended to be disinfected with a weak solution of potassium permanganate for a quarter of an hour, and the cut rhizomes (according to many years of experience of gardeners) should be dried in the sun, powdering the cut with a mixture of crushed coal and sulfur in equal proportions.
Irises: when to transplant?
When choosing a landing site for irises, preference should be given to well-protected, sunny places, taking into account the light-loving nature of plants. Groundwater should not be located close to the soil surface, otherwise there is a risk of rotting for the roots.Before planting, it is recommended to fertilize the soil with mineral fertilizer. Planting, which is about 3 cm deep, is made in a previously prepared hole with a mound in the center, to which the rhizome of the plant is evenly distributed. The distance between the bushes of irises should be kept at least half a meter.
So, if irises grow on the site, when to replant them, in order to get high-quality, abundant flowering bushes? It is optimal to replant the plants immediately after they bloom or at the end of the growing season; this operation at other times may cause the death of the flower due to its insufficient rooting.
Planted at the end of the summer irises partially bloom by the spring of next year; full bloom can be observed in 2-3 years after planting. In order to avoid rhizome rushing to the surface of the soil, which may entail a reduction in flowering,transplanting iris by dividing should be done every 3-5 years; on average, a plant characterized by winter hardiness and the ability to grow in open ground without shelter for the winter can grow in one place for about 7 years.
Features care for irises
Care for irises is simple and consists in loosening and weeding the soil, feeding and irrigating it, which is recommended to be reduced starting in the second half of summer.
The first dressing should be done in early spring, sprinkling on the soil where the irises, mineral fertilizer will be sprung at the rate of 100 grams per unit. The second time the use of fertilizers is recommended during budding - the beginning of flowering. The third time fertilizing will be required in August (potash-phosphate fertilizers), during the second phase of iris budding. This will increase their stability and will contribute to a better wintering of the plant.
Diseases and pests of iris
Like many plants, the iris is a flower that is prone to attack by pests, in particular, it is periodically chosen by gladiolus trips. The presence of the latter can be determined by the depressed appearance of the leaves losing their wax coating.To combat such a pest should use the drug "Confidor" at the rate of 1 ml per 10 liters of water.
Of the diseases of the iris most often affects rot, the occurrence of which often occurs due to overmoistening of the soil at the growth site. When this problem is detected, the plant needs to be dug out, cut out all the affected rhizomes, and determine the healthy root for about half an hour into a solution prepared from the “Chom” preparation (according to the instructions). In sunny weather, rhizomes are recommended to hold in the open air for about 12 hours, periodically turning them over.
Heterosporosis is a disease that often affects irises at the end of the summer season. Small brown spots on the leaves will tell about his presence. You can save the iris by cutting off the affected parts of the plant, which must be burned. The bush itself should be treated with copper sulfate at the rate of 50 grams per 5 liters of water.
In any case, do not give up the presence on the site of such beautiful flowers as irises. When to transplant them, decide the gardener. The optimal period is the end of the growing season.
