When is teh best time to divide iris? Can it be done now? I also have a hydranga (the kind that dies back) that has never flowered since I planted it. Do you have any tips? It always has great foliage but no flowers.

Thank you

Mid August is a perfect time to dig and divide iris so I'd go ahead and tackle the job now. Hydrangeas can fail to bloom if they do not get enough sunshine (4 hours of morning sun is best) or if they are the type that flowers on old wood. Since yours dies down to ground level each year, if it is the type that develops flowering shoots on old wood, it will never flower for you. You'll need the kind of hydrangea that flowers on new growth such as the Endless Summer type of hydrangea.
