How often to water Iceberg Climbing roses in Arizona?
Roses, including the Iceberg variety – a great choice for a strong white rose, are shallow surface rooting plants, that lose a lot of water from their large volumes of flat thin leaves. As such they benefit from regular watering, and I’d recommend watering them every day in Arizona. They’re currently flowering in California, so I assume that yours may also be too. If you also mulch them, this will help retain some of the water, as well as release nutrients down to the roots, helping them to grow and flower more prolifically. You can use animal manure of compost for this. I’d also recommend giving them a good feed, as their leaves are showing some signs of distress. Hope this helps. Good luck!
