How do I take care of my tree roses? Is there special winter care?

Tree roses are not hardy enough to stay outside in the winter but don’t bring them inside your house because they can be finicky and hard to keep happy. Keep them outside till Thanksgiving and then bring them into your garage and care for them there.

Q: What is the difference between annuals and perennials?

Annuals are plants that complete their life cycle in one growing season (spring – fall/frost). Perennials are plants that live for more than two growing seasons. They die back in winter and re-emerge in spring.

It grows at a slow rate, and under ideal conditions can be expected to live for 50 years or more.

This tree should only be grown in full sunlight. It is very adaptable to both dry and moist growing conditions, but will not tolerate any standing water. It is not particular as to soil type or pH. It is highly tolerant of urban pollution and will even thrive in inner city environments. This is a selection of a native North American species.
