caring for viburnums
I just completed a big landscaping job in early June. We have had temps in the 100s the last two weeks and despite watering daily, my viburnum is starting to suffer from wilted, brown leaves. I feel the soil every day and if it is moist then I will skip watering. Typically, I use a nozzle set to the soaker setting and hold it on the base for 60her seconds. Am I watering too much or not enough? The same thing (leaves turning brown and wilting) is happening to my knockout roses and one of my oakleaf hydrangeas. Help!
It is common for them to look a bit ragged when newly planted, as they are re-adjusting to their new surroundings, especially in very high temps. Also, just to make sure that nothing is restricting the roots from taking in water, tamp down around the plants to collapse any air pockets that may be present.
