They can withstand temperatures from degrees Fahrenheit high and temperatures up to degrees Fahrenheit, but these temperatures are deceiving.

There is no need to fertilize the empress tree. It will grow readily in most conditions and does not need much of a boost to get it to thrive. It is known as a pioneer species and can grow in conditions that other species find inhospitable. A pioneer species is the first species to colonize an ecosystem that is previously damaged or disrupted. Taking on this chore can be a matter of preventing property damage and trying to manage the insanely fast growth.
You will want to clear branches that may be susceptible to snow or wind damage or present hazards. But be careful when pruning: empress tree wood is notoriously weak, and making poor cuts and using improper pruning technique can lead to further weakening the wood. To curb the growth and keep the tree a manageable size, you will want to cut your tree down to about five feet every autumn. Doing this will allow the tree to grow back and bloom every spring.
If rather than having blooms you'd prefer to have an interesting shrub with fascinating foliage 36 inches in width, cut just above the ground level. Doing this will not let flowers or fruit appear but will create some spectacular foliage. If you want a flowering tree that isn't likely to become a pest, go for a dogwood or a nice magnolia.
