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 can I move my Siberian Iris?

The best times of the year to divide an iris are October to early November and late March through April – basically as soon as the ground is thawed in the spring. It will be a big, heavy clump so it can be hard to get out of the hole without help.

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. Cutting peonies in the fall helps remove foliar diseases and reduce infection next year. Simply cut all the growth off at the soil level and discard.

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 long can you keep iris bulbs before planting?

Iris bulbs won't last a very long time in storage, so you should consider options for transplanting or forcing indoor growth for the bulbs after 3-4 weeks of storage. If you notice a lot of your bulbs are beginning to rot or dry out, plant them as soon as possible.

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.
