Dividing irises australia

What is the best time to divide irises?

When can I move irises in Australia?

Bearded Iris are ideally divided late summer to autumn, once they have finished their flowering. Moving them at other times is ok, but it will disrupt their flowering. 1. Simply dig under the clump with a fork or spade, ensuring you don't run through the rhizomes as you do.

Should I deadhead irises?

Can you move irises in the spring?

What to do when irises have finished flowering?

How do you care for irises in Australia?

Plant the rhizome so the rhizome is facing north and the fan of leaves is at the back, then backfill to cover the roots. Keep a light cover of soil on the rhizome to protect it from the hot Melbourne sun. Water in well, then just once a week; overwatering is the worst you can do for iris.

Why do irises not bloom?

Poor rhizomes or bulbs are often the cause of no flowers. ... Irises in shady locations may fail to form blooms. Depth of planting can also cause iris plants not flowering. Rhizomes should be near the soil surface, ideally with the tops at or slightly below the soil surface.

Can you dig up bulbs in the spring?

The best time to dig up spring-flowering bulbs, such as your daffodils, is about six weeks after they finish blooming. At this point the foliage will have died back (if it hasn't, wait longer) but you can still see it, which makes locating the bulb easy.

Should you soak iris bulbs before planting?

Soak rhizomes for 10 minutes, rinse well, and lay out to dry. It's OK to wait days or even weeks before planting, but sooner is better. As long as the iris is in a sunny spot where its rhizome can stay dry, all will be well.
