Q.pruning for shape
Can I prune a burning bush in September for shape?
Wait until the plant goes dormant. Right now the shrub is preparing for winter which means carbohydrates flow from the leaves to the roots to ensure winter survival. Since pruning spurs new growth, the flow is reversed leaving roots more depleted than they should be. New growth at this point does not have time to harden off - a process that takes weeks for a shrub or tree. This new growth might succumb to winter kill or winter die-back. Burning bush, Euonymus alatus, is an easy care shrub. It is tough and hardy. Pruning in fall is not advisable in climates where plants go dormant for winter. Minor trimming of soft tips is OK.
