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.

General Garden Use

Planting & Growing

Howell's Dwarf Tigertail Spruce will grow to be about 20 feet tall at maturity, with a spread of 15 feet. It tends to fill out right to the ground and therefore doesn't necessarily require facer plants in front, and is suitable for planting under power lines. It grows at a medium rate, and under ideal conditions can be expected to live for 50 years or more.

This shrub should only be grown in full sunlight. It does best in average to evenly moist conditions, but will not tolerate standing water. It is not particular as to soil type or pH. It is somewhat tolerant of urban pollution, and will benefit from being planted in a relatively sheltered location. This is a selected variety of a species not originally from North America.
