DESCRIPTION OF PLANTING AND DIVISION OF BEARDED IRIS
Species irises are able to grow in one area for decades. And cultural bearded ones recommend dividing and transplanting to a new place every 5 years. Some collectors do this annually (in July) if possible. Then the bushes get sick less often and bloom more magnificently.
You can divide the bush both into large parts, and cut off sections of rhizomes 5-15 cm long with leaf fans with a knife. Immediately you need to disinfect the places of cuts on the mother plant.
Divide in the constriction area: there is a smaller cut area and denser tissue.
Shorten the leaves of the delenki to 15-20 cm, and the roots to 10 cm and wash thoroughly from the ground. In this case, it will become clear whether there are foci of diseases on them. After that, completely remove dead and rotten roots, as well as sections of the rhizome - to healthy tissues.
Soak the delenki in a bright pink solution of potassium permanganate for 20-30 minutes, dropping the rhizomes with roots and the root collar (the place where the leaves are attached) there.
Then, after drying, grease the cuts and all damage with brilliant green. Found rotting areas? Treat with fungicide.
Divided irises plant only after 5-10 days, when the sections cork. Moreover, when drying in clear weather, keep the delenki from morning to evening in the open sun, turning them towards it alternately with the upper and lower sides. Don't worry about dried roots. After planting, they will quickly grow.
FOR THE NOTICE
Often, irises with flowers are now being sold at markets and exhibitions. They take root quite well, but it must be borne in mind that such plants are weakened. Immediately after purchase, cut the peduncle and shorten the leaves. To improve root formation and relieve stress after planting, pour "Zircon" under the root (in standard dilution).
TIPS FOR PLANTING AND DIVISIONING IRIS
The "back" of the iris should be illuminated by the sun's rays for as long as possible. For this purpose, the rhizome is oriented from south to north so that it is not covered by a fan of leaves. Although I have heard directly opposite recommendations in this regard. In my experience, this moment is not so important, as long as there is more sun.
For planting, they dig a wide hole, in the middle of it a mound of earth is poured, rising above the level of the ridge (taking into account the subsequent shrinkage of the soil due to compaction). A layer (at least 5 cm) of coarse-grained sand mixed with ash is placed under the delenka. The rhizome is planted on the sand, the roots are straightened along the slopes of the mound. After that, they are covered with soil to the level of the bottom of the rhizome and watered around the circumference, without falling into the delenka. If necessary, pour earth with sand or clean sand.
The leaves are cut with a wide wedge of the knife, pointing upwards. With this technique, the old records are shortened as much as possible, which will die off in the first place anyway. Pruning allows you to reduce the evaporation of moisture and does not allow the wind to knock down delenki with too short roots. In no case do not bury the rhizome for stability! It is better to tie the iris to a peg for a while until it takes root.
GROWING BEARDED IRIS - ADVICE AND FEEDBACK
When I first became interested in growing bearded irises, I was pleasantly surprised that 10-15 varieties can fabulously transform a site into the peak of its flowering.
As my many years of experience have shown, irises are not only decorative, but also unpretentious. If you know some secrets of their cultivation, you can achieve excellent results.
The best time to purchase and plant irises is from late July to early September. The delenka should consist of 1-2 annual links of the rhizome, slightly trimmed roots and a shortened fan of leaves.
I choose a place for a plant elevated, open, sunny, with light, loose soil.
I plant in pre-prepared holes at a distance of 30-40 cm between specimens and 50-60 cm between rows. At the bottom of each I pour a mound of earth, evenly distribute the roots along its slopes, sprinkle them with soil, compact with my hands and water. The rhizome should not be deeply buried. It must be at ground level, otherwise the irises will not grow well and will not bloom.
In the first year, in November-December, I cover the plantings with spruce branches. This will not be needed later.
Before flowering, I definitely tie up flower stalks of tall and medium-sized varieties so that they do not break off in strong winds.
Irises are drought tolerant. I water them with warm water in the evenings rarely, but plentifully and only during mass flowering. Sometimes I add a little potassium permanganate to the water.
After the flowers wither, I cut off the flower stalks.
Over the years, the rhizome grows, and the bushes become crowded. In this case, I thin out the curtains or plant them.
With moderate air temperature (+ 18-20 degrees) and the absence of prolonged rains, bearded irises bloom for up to 10 days. Inflorescences cut with the first upper flower half-opened stand in a vase for about a week.
