Arrowwood viburnum shrubs are a gorgeous addition to any garden, with their lush green leaves, fragrant white blooms, and clusters of blue-black berries. However, like any plant, arrowwood viburnums require regular care and cleaning to stay healthy and vibrant. Proper cleaning not only enhances the shrub’s beauty but also prevents diseases, promotes airflow, and encourages new growth. Read on as I share my tips for effectively cleaning arrowwood viburnum shrubs.
Why It’s Important to Clean Arrowwood Viburnum Shrubs
Cleaning arrowwood viburnum shrubs is essential for several key reasons
-
Removes dead or damaged branches, leaves, and debris – This improves aesthetics
-
Prevents disease spread by eliminating infected or infested parts
-
Allows better airflow within the shrub, reducing fungal infection risks.
-
Encourages new growth by pruning away old branches.
Neglecting to regularly care for and clean arrowwood viburnum shrubs can lead to a host of issues, including pest infestations, fungal diseases, stunted growth, and lackluster blooming. So roll up your sleeves and let’s get cleaning!
Helpful Tools to Have On Hand
Before tackling arrowwood viburnum shrub cleaning, assemble these useful tools:
-
Pruning shears – for cutting back small branches and stems
-
Loppers – for thicker branches that shears can’t handle
-
Gloves – to protect your hands from cuts and scratches
-
Rake – for gathering fallen leaves and debris around the shrub
-
Trash bags – for collecting and removing waste
-
Compost bin – for recycling clippings and organic debris
Step-by-Step Guide to Cleaning Arrowwood Viburnum
Follow these simple steps for cleaning arrowwood viburnum shrubs:
1. Inspect Entire Shrub
Carefully examine the entire shrub for any dead, damaged, or diseased branches. Check undersides of leaves for pests like spider mites. Also look for signs of fungal issues.
2. Prune Out Problem Areas
Use pruners and loppers to remove all dead or diseased wood. Make cuts just above healthy buds or branch junctions. Disinfect tools between cuts to prevent disease spread.
3. Trim Overgrown Sections
Selectively trim back any excessively long or overgrown branches. This maintains desired size and shape. Angle cuts above leaf nodes to encourage bushy regrowth.
4. Eliminate Suckers
Remove all suckers – fast growing shoots emerging around the base. This prevents them from stealing nutrients.
5. Clear Fallen Debris
Rake thoroughly around the shrub to eliminate all fallen leaves, twigs and debris. Prevent fungal issues and deter pests.
6. Safely Discard Waste
Bag up all clippings, leaves and debris. Properly dispose of diseased trimmings. Compost healthy material. Remove waste promptly.
7. Apply Fresh Organic Mulch
Put down 2-3 inches of shredded bark, leaves, or other organic mulch around the shrub. This retains moisture, deters weeds, and feeds the soil.
8. Check Soil Health
Test soil pH and nutrients around viburnums annually. Address any deficiencies with organic amendments as needed. Proper soil health prevents many issues.

Step 4: Step back frequently to refocus
After every few cuts, observe your viburnum from multiple vantage points at least 10 feet away, noting how your pruning has changed the shrub’s shape and density. Do any branches seem out of place? Where is there crowding? Which branches identified in step 1 have not been addressed? Plan your next cuts while standing at a distance.
Step 3: Begin structural pruning by visualizing the viburnum from above
I think of this as “the quadrant method.” The trick is to envision the circular or oval-shaped footprint of the shrub as it would look from above and then to divide it into four sections that meet at the center. Focusing on the shrub’s base, look for stems that emerge from the ground in one quadrant but extend into a different quadrant. Consider removing these twisting stems at ground level.
Next, raise your focus to the plant’s midsection, again looking for stems that cross through the midline into another quadrant. Consider cutting these stems back to a branch union at the collar. The goal is to create a more organized, balanced canopy by reducing crossing branches.
Doublefile viburnum, the great exceptionExercise extra caution when pruning doublefile viburnums. Their natural habit is tiered, which adds a uniquely graceful, layered form to the landscape. Most of your efforts should focus on removing vertical suckers and water sprouts that interrupt the tiered branch arrangement. For this species, I recommend pruning no more than 15% to 20% of its live branches. Any hard pruning will result in the excessive production of water sprouts and suckers. |
