What fertilizer should I use on my burning bushes? They are planted in the ground
Burning Bush Fertilizer
In general, burning bush, Euonymus alatus, does not need fertilization. It is also late in the year, depending on where you live. Fertilizing tells the plant to grow right when it should be shifting to hardening off for winter. The result of late fertilizing is growth that might succumb to winter kill. If you want to fertilize in spring, any general shrub fertilizer will do. I would not use a high nitrogen product.
