Many shrubs will grow very well in United States Department of Agriculture (USDA) Hardiness Zone 5. A number of shrubs grow very well in Zone 5, including boxwood, golden currant, Korean rhododendron, sumac, witch hazel, and lilac. With proper planting and care, these and many other shrubs can thrive in Zone 5. Zone 5 experiences winter temperatures that vary between -10 degrees F and -20 degrees F. Zone 5 includes parts of Colorado, Nebraska, Kansas, Iowa and Missouri, among others.
Remove your shrub from its nursery container and plant it in a hole slightly wider than the size of the root ball. Plant after the last expected hard frost. This date will vary, depending on your latitude. In more northern latitudes, the planting date will be later than more southern areas that are also Zone 5. Fill in the hole and water the shrub thoroughly. Keep your shrub watered throughout its first spring by checking the moisture levels and watering the shrub whenever the top 1/4 inch of soil feels dry.
Mulch the shrub to prevent water loss and to protect the roots in case of an unexpected cold snap, which is any unexpected spring drop in temperature to below freezing that is long enough to freeze the soil.
Cover your shrub with plastic if an unexpected hard freeze is forecast.
Run an extension cord under the plastic and place a lamp with an incandescent fixture under the plastic if the freeze might be unusually cold.
