Conclusion

Fertilizer is not typically necessary for boxwood shrubs, as they are relatively low-maintenance plants. However, if you notice that your boxwood shrubs are not looking as healthy as they should be, you may want to consider fertilizing them.

The best time to fertilize boxwood shrubs is in early spring, before new growth begins. When choosing a fertilizer, look for one that is specifically designed for boxwood shrubs. Apply the fertilizer according to the instructions on the package.
