Viburnums are low-maintenance shrubs that thrive in various conditions, but they appreciate a balanced diet of nutrients to reach their full potential.
Choose a fertilizer specifically formulated for acid-loving plants, as viburnums prefer a pH range of 5.5 to 6.5.
Apply fertilizer according to the product instructions, typically once a month during the growing season (spring through fall).
Avoid overfertilizing, as it can damage the plant's roots and lead to nutrient burn.
Fertilization not only provides essential nutrients but also enhances the plant's resilience to pests and diseases.
Healthy viburnums produce more vibrant foliage and abundant blooms, adding aesthetic value to your landscape.
A well-nourished viburnum can withstand harsh weather conditions, such as drought and extreme temperatures, better than its undernourished counterparts.
Observe your viburnum's growth patterns and leaf color. Yellowing leaves may indicate nitrogen deficiency, while stunted growth could suggest a lack of phosphorus.
Conduct a soil test to determine the pH level and current nutrient levels in your soil. This information will help you tailor a fertilizer regimen specific to your plant's needs.
Consider the type of viburnum you have. Different species may have slightly varying nutritional requirements.
Overfertilizing: As mentioned earlier, excessive fertilization can harm your viburnum. Follow the recommended application rates and avoid applying fertilizer more frequently than necessary.
Using the wrong fertilizer: Acid-loving plants like viburnums require fertilizers tailored to their specific pH preference. Avoid using alkaline fertilizers or those intended for other types of plants.
Fertilizing at the wrong time: Viburnums benefit most from fertilization during the active growing season. Avoid fertilizing in winter or when the plant is stressed due to drought or extreme temperatures.
Incorporate organic matter into your soil to improve drainage, nutrient retention, and overall plant health.
Mulch around your viburnum to suppress weeds, retain moisture, and regulate soil temperature.
Water deeply and regularly to encourage root growth and nutrient uptake.
Prune your viburnum regularly to remove dead or diseased branches and encourage vigorous new growth.
Table 1: Recommended Fertilizer Rates for Viburnums
Plant Size | Nitrogen (N) | Phosphorus (P) | Potassium (K) |
---|---|---|---|
Small (1-2 ft) | 1/4 cup | 1/4 cup | 1/4 cup |
Medium (3-4 ft) | 1/2 cup | 1/2 cup | 1/2 cup |
Large (5+ ft) | 1 cup | 1 cup | 1 cup |

Nutrient | Optimal Range |
---|---|
Nitrogen | 2.0-2.5% |
Phosphorus | 0.15-0.25% |
Potassium | 1.0-1.5% |
Calcium | 1.0-2.0% |
Magnesium | 0.25-0.50% |
