Planting Siberian Iris
Upon receipt, soak your rhizomes in water overnight. Plant your Siberian Iris deeper than other Iris, covering the rhizomes with one or two inches of soil. Space your plants two feet apart. Siberian Iris prefer acidic soil (pH 5.5 to 6.9).


Then, how do you grow Siberian Iris?

Siberian irises perform best in moist, well-drained, fertile soils. However, they will tolerate poor, dry sites. They can be grown in partial shade to full sun. Siberian irises are usually planted in spring or late summer.

Beside above, why is my iris sibirica not flowering? When you notice iris plants not flowering, the cause can stem from a variety of issues including weather, soil fertility, overcrowding, unhealthy rhizomes, insect or disease attack, planting depth and even site conditions.

Similarly, how do you take care of Siberian iris?

Siberian Iris Care Keep the soil consistently moist until the plants are established, about a year. Water established plants regularly when drought conditions exist. Feed Siberian iris plants in spring with a nitrogen-rich fertilizer and fertilize again when blooms are spent.

Should I deadhead Siberian Iris?

If you enjoy deadheading plants and prefer a pristine garden, deadheading Siberian iris blooms will not harm the plant either. For best plant appearance when removing spent Siberian iris blooms, cut the whole flower stalk back to the plant crown immediately after the flowers fade.

Should I cut back my Siberian Iris?

Cut back Siberian foliage only after it turns brown and withers in late fall. Then, cutting off all leaves an inch or two above ground level is recommended. PESTS: Siberians are more resistant to disease than other garden irises, but do suffer from scorch in those areas where this attacks other Iris varieties.

What to do with Iris after flowering?

After blooming is finished, cut flower stems down at their base. But do NOT trim iris leaves after they have finished blooming. Leaves carry on photosynthesis for next year's growth. Cut off brown tips—and cut the flowering stalk down to the rhizome to discourage rot.

When should peonies be cut back?

Once the plants start to yellow or brown in the fall they should be cut to the ground. Early fall or after the first frost is the ideal time to cut back the plants.

Are iris flowers deer resistant?

Deer also turn their noses up at fragrant plants with strong scents. Herbs such as sages, ornamental salvias, and lavender, as well as flowers like peonies and bearded irises, are just “stinky” to deer. Neither do deer (unless they're desperate). Plants such as lamb's ear are not on their preferred menu.

What do you do with hostas in the fall?

Cut back the rest of the greenery on hostas after it has died back in fall – October or early November in coastal areas and up to a month earlier inland. Although it would not hurt the plant to leave withered foliage on the plant, the foliage gives slugs, weevils and assorted rodents a handy shelter until spring.

What is the best time to divide irises?

Mid- to late-summer is a good time to divide bearded irises. You want to make sure that the roots have ample time to grow before winter. You can usually tell that your irises are ready to be divided when a clump looks overgrown, with rhizomes starting to grow into each other and popping up from the soil.

How do I get my iris to bloom again?

Remove rhizomes from the soil carefully with a garden fork and divide them with a sharp, clean knife so each new section has one to three leaf fans and healthy roots. Replant immediately. Most irises prefer well-draining soil in a sunny location. Your irises should produce more blooms the next year.
