You can transplant irises to another place at the beginning of the growing season or in the summer. The event is necessary for a full growing season, therefore it is included in the conditions of agricultural technology. Regardless of the variety, leaving a crop in one area for more than four years is unprofitable. Transplantation involves dividing the bush. This will help not only propagate, but also rejuvenate the plant.
Why do you need to plant and replant irises?
As long as the iris stays on the site, it will grow roots. In late autumn, the green mass dies off; all replacement axillary buds formed during the growing season enter the dormant phase until spring. At the beginning of the season, a root up to 15 cm long grows from each.
Irises bloom fully in one area for no more than four years, then they need to be transplanted to another place. During this period, the root system grows so much that the links appear above the surface; a dense weave remains in the soil in the form of a lump, which absorbs most of the nutrients and prevents the development of new branches.
In the center of the bush, the old rhizomes die off, a void appears in the form of a nest - this is the first sign that the crop needs to be replanted
The soil is depleted, the aboveground part develops slowly, the iris lags behind in growth, budding becomes weak, then the plant stops blooming.
If irises are not transplanted to another area in time, they lose not only their decorative value, but also their ability to resist infection. The bush begins to hurt, every year there are fewer leaves and flower stalks, they are underdeveloped, the plant simply degenerates.
If it was not possible to transplant the irises to another place in the spring, this event can be carried out at any stage of the growing season, except for the flowering period. The divided bush quickly takes root and begins to intensively grow roots and green mass.
When can irises be transplanted to a new location?
Irises can be transplanted to another location in spring or summer. At the beginning of the season, the timing is dictated by the weather; in the middle of the growing season, the duration of flowering of the variety is dictated. The need to transplant a plant to another area is determined by the state of the above-ground mass and age. The best time for transplantation is when the iris is three or four years old. At this time, it grows so much that it is ready for division and quickly takes root in another place.
When to replant irises in spring
Replanting the plant in early spring is the best propagation option. A new bush can produce several stems and bloom if the event is carried out on time and correctly. It is better to transplant irises to another place when the leaves are just beginning to form.In the southern climate, if weather conditions permit, it is advisable to do so before the start of the growing season.
The frost-resistant plant begins to grow in early spring, when the daytime temperature reaches +8 0C and above. At this time, the earth warmed up enough to replant the crop. Taking into account the fact that each region has its own climate, they are guided by these parameters.
When the first growth appears, you can start working
The approximate timing of iris transplantation in the Middle Zone is the end of April, in the South - in March or early April. In Siberia or the Urals, you can move a plant to another place 7-10 days later than in the Central regions.
When to replant irises in summer
Each variety of irises has its own flowering period, usually June-July. The length of the cycle also varies, so it is difficult to determine a clear time frame. If in the spring irises begin to be replanted as soon as the weather permits, then the summer dates can be oriented toward the end of flowering. As soon as the last petals on the flowers have wilted, they begin transferring.
How to transplant irises correctly
To identify the iris to another area, it is completely removed from the soil, the root is examined; if the fragments are in doubt, they are removed. Then the planting material is prepared:
- The root is completely freed from the earthen coma.
- Cut into pieces so that each section has 2-3 leaf rosettes.
- Treat with any disinfectant solution.
- The sections are covered with crushed activated charcoal or charcoal.
- Leave in the sun to dry for 2 days.
Each plot must have a root
How to plant irises correctly
It is advisable to choose another place, not much different from the previous one: sunny, sheltered from the wind and without stagnant groundwater. The area allocated for plots is dug up and organic fertilizers are applied. Prepare a nutrient mixture from peat and turf soil, add potassium. The crop grows on neutral or slightly acidic soils; the composition is adjusted if necessary.
You can transplant irises to another place in summer or spring as follows:
- Leaves and flower stalks are cut at an angle (close to the root).
- A planting hole is made taking into account the height of the root and the thickness of the nutrient mixture layer. Vegetative buds should remain at ground level.
- Part of the prepared substrate is poured onto the bottom of the pit.
- Place the seedling on a slight slope, distribute the root system, it should not be intertwined.
Sprinkle with soil, leaving the upper part of the root on the surface
- The soil around the iris is compacted, done carefully so as not to damage the buds, and watered.
If you succeed in replanting in the summer, immediately cover with mulch. This event may not be held in the spring.
Aftercare
Transplanting the plant to another place is the first and not the most difficult stage of the work. Without proper agricultural technology, the iris may not bloom next year. The main task is for the bushes to take root faster.
Caring for the crop consists of the following activities:
- After planting in another place, the iris is watered abundantly. The procedure is carried out regularly to prevent the earthen ball from drying out, but also not to fill it so much that the water stands.
- After spring work, the plant is fed with nitrogen fertilizers so that it better forms the above-ground part.A week after placement, phosphate agents are applied to another location to promote better root development.
- Periodically loosen the soil and remove weeds.
- If you had to replant irises in the spring, then cut off the leaves in late autumn. In summer, pruning of iris is carried out while dividing the bush.
During abnormal frosts, the young plant is covered with spruce branches and a small snowdrift is made on top.
Conclusion
You can transplant irises to another place in the spring, when the above-ground mass begins to form. It is necessary to carry out the work as early as possible, then the plant will more easily withstand stress and bloom in due time. You can transplant the plant to another place in the summer, after flowering. Before frost, the irises will take root and quietly overwinter.
