Dutch Iris


By Bryony

I have some Dutch Iris bulbs which say on the packet to plant from January to March. I was just looking for instructions on how deep to plant them and found a site which says that they should be planted in the Autumn. Can I still plant them now or is it too late? If I do plant them, when are they supposed to flower? (I live in the south of England).

Also, can I grow them om containers and if so, how deep would it need to be?




Yes, plant them, or lose them! The general rule of thumb is to plant twice as deep as the size of the bulb, so if they measure 2", then plant them 4" down.

They may flower a bit later than usual, but never mind.

They flower in late spring.

I have just planted my dutch iris and i did the same last year and they flowered in mid/late may. so dont worry. I have some from 8yrs ago and leave them in the ground and they come up every year.

I have 100 dutch iris that I bought 3 weeks ago. They need to go in the ground now but my ground is still frozen solid. I'm keeping them in a cool dark place and keeping my fingers crossed they will be OK.

pot them up gilli, i put 4 in a 4" pot and then pot out when they are showing their 'noses'. i've never had a problem apart from space in the coldfrme/greenhouse; as long as they are sheltered from the worst of the frosts

Thanks everyone!

Can I plant them in a trough which is about 18cm deep or is that too shallow? How closely can I plant them?

They do get quite tall - up to 18", so they might look a bit unbalanced in a shallow trough - but anyway, plant them about 4" apart in clumps.
