Irises are a favorite plant of flower growers. A wide variety of color palette, bright, albeit not long-term flowering, determined their name: the flowers are named after the goddess of the rainbow Iris.

So that the plant does not cease to delight with its juicy colors, you need to know when to transplant irises. The procedure is usually carried out after flowering. The timing varies slightly depending on the perennial variety.

Transplant time

Even specialists are sometimes confused in the botanical classification of the iris genus. Therefore, consider a simplified variety of species, most often found in personal plots:

• bearded varieties are distinguished by a strip of dense villi in the center of the petal. The transplant is carried out 2–4 weeks after the end of flowering. Approximate terms: from the second decade of July to the first decade of August;
• Siberian irises grow into large, spectacular bushes and remain incredibly beautiful even after flowering. But unfortunately, they do not have a scent. It is better to replant flowers at the end of July or at the very beginning of the third summer month;
• Japanese varieties captivate with exquisite and very large flowers. In a new flower garden, the plant should be planted from early to mid-August.

It is recommended to transplant irises after flowering when young links are formed on the rhizome, but flower buds have not yet set. Growths should be 3 centimeters long and 1–2 centimeters in diameter.

The roots that have just begun to grow are incredibly fragile, so breaking them is not difficult. If you are late with dividing the bush, you will have to wait until the end of August or early September. At this time, the roots will become stronger, it will be more difficult to damage them, which means that the cuttings will take root well.

Site preparation

Before replanting males, you need to prepare a new site:

• the bed should be well lit … Plants can only tolerate light partial shade in the afternoon;
• choose places with a low groundwater table or create a slightly raised flower garden to avoid moisture stagnation;
• the soil should be slightly acidic or neutral … You can add a sandy-peat mixture to loams, and clay soil to sandy soil. Wood ash should be added to heavy soil, and dolomitic flour or chalk should be added to acidic soil. The area for bearded irises can be enriched with compost, oily garden soil and potassium monophosphate;
• spill the selected area with fungicides and herbicidesto disinfect the land and prevent the appearance of weeds;
• make holes 30-40 centimeters apart … For tall varieties, a distance of 70 centimeters should be observed. The depth should be equal to the length of the roots.

Before planting on the bottom of the holes, heap a mixture of soil and mineral products with a high content of phosphorus and potassium.

Transfer

After you know when to transplant irises after flowering, you should familiarize yourself with all the rules of the procedure. It is not very difficult and is carried out in several simple steps:

1. Use a pitchfork to dig out the bush you want to plant … Shake off excess soil. If the roots are very dirty, you can rinse them with water.
2. Remove dried or diseased leavescarefully inspect for rotted parts.
3. Shorten the rootsleaving 7-10 centimeters.
4. Pruning shears, sharpened scissors or a sharp knife cut the leaves … Their length before planting should be no more than 15 centimeters.
5. Divide the mother bush into several parts.
6. Dip cut in a weak solution of potassium permanganate.
7. Sprinkle the cuts crushed charcoal or activated carbon, with a slight admixture of sulfur. Some flower growers recommend treating slices with brilliant green.
8. Lay out the cuttings in the sun and dry a little.
9. The roots of the obtained annual blades can be sprinkle with an agent to stimulate root formation.
10. Plant in pre-prepared holes … The roots should be evenly distributed on the mound of soil and fertilizer you made earlier. Press them into the soil.
11. Cover the depression with earth … Remember that the rhizomes should be flush with the ground. When planted deeply, the plant simply will not bloom or will disappear.
12. Water the flower. The next moistening of the soil can be carried out only after 3-5 days.
13. If the weather is too hot, the bush needs create artificial shadow.

Do not forget to mulch the area after planting

If you just transplant a bush, without dividing, you need to carefully dig it out without damaging the roots and transfer it to a new flower garden along with an earthen lump.

Now you know when to replant irises after flowering. A similar procedure is performed every 3-5 years. It is enough to replant Siberian males every 10 years. If you do everything right, your perennials will tolerate winter well, and in summer they will delight you with bright, lush and juicy blooms of all shades of the rainbow.
