A lot is not always particularly useful; this also applies to fertilizing the viburnum bush. On the contrary: with too much fertilizer you can actually cause damage to this shrub or prevent it from blooming lushly and magnificently.
How should you fertilize a viburnum bush?
A viburnum bush usually requires little to no fertilizer. If the soil is poor in nutrients, complete organic fertilizer can be used. Potted plants benefit from flowering fertilizer with an increased phosphorus content. Avoid too much nitrogen as this will affect growth and flowering.
Do all viburnum species need the same amount of fertilizer?
The amount of fertilizer that a snowball bush needs depends not only on the type of bush but above all on the location. Most of the time the viburnum doesn't need any fertilizer; mulching in the spring is often enough. However, if the soil is very poor in nutrients, then adding a complete organic fertilizer (€47.00 on Amazon) makes sense.
Potted plants also often need additional nutrients. A so-called flowering fertilizer with a slightly larger proportion of phosphorus is recommended here, especially during the flowering period. You can improve very moist soil a little with slightly acidic compost. If your snowball gets too much nitrogen, it will weaken and bloom less. Weakened plants are also more susceptible to diseases and pests.
What else is important in care?
For a beautiful flower, the snowball needs above all enough light or sun and enough water. Even though abundant watering is recommended almost everywhere, many types of viburnum do not tolerate waterlogging. This requires a little tact from you.
On the other hand, in many varieties the soil can be moist, sometimes even wet. It is best to inquire about the suitable soil for your chosen snowball when purchasing. Furthermore, the plants in this genus are quite easy to care for and many of them are also hardy.
The best tips for fertilizing the viburnum bush:
- fertilize little or not at all
- too much nitrogen can damage growth and flowering
- Do not fertilize well-mulched shrubs at all
- Use complete organic fertilizer if the soil is very poor in nutrients
- If the soil is moist, perhaps add some (slightly acidic) compost to it
- Provide potted plants with flowering fertilizer (increased phosphorus content)
Tip
If the soil conditions are good, your snowball doesn't need any fertilizer. Monitor your plants and only intervene if you notice an actual need.
