Breaded Iris Question?
Hi all, we moved into our house two years ago, it's been a project house to say the leasT. I've kept on top of the garden but this year I've started doing more. There were some bearded iris in the garden already and I'm wondering if I need to cover the roots? They are all on show between the plants. Is this normal or should I use compost the cover them? ive read up on dividing them which I'm going to do just wondering if they need more than just this? Thanks
