Fringe tree is an ornamental plant that is native to North America. It is a deciduous tree that grows to a height of 20-30 feet and has a spread of 15-20 feet. The tree has a rounded crown and the leaves are alternate, simple, and have toothed margins. The flowers are white, borne in clusters, and have 5 petals. The fruit is a drupe that is dark blue in color and has a single seed.

About soil condition, the Fringe tree grows well in average, medium to wet, well-drained soils. It does not do well in extremely dry or wet soils. It prefers slightly acidic to neutral soils (6.0 to 7.0 pH), but it can grow in mildly alkaline soils.
So, like the other trees, the Fringe tree needs sunlight to grow. However, it can also tolerate some shade, which makes it a good choice for landscaping. The Fringe tree can reach a height of 20-30 feet and a width of 15-20 feet. It has a rounded crown and produces small, white flowers in the spring.
The temperature condition that is most ideal for the growth of the fringe tree is a temperature that is between 60 to 70 degrees Fahrenheit. This temperature condition is perfect for the growth of the fringe tree because it is not too cold and not too hot. The fringe tree will grow the best when the temperature is in this range.
Ideal humidity condition for this plant is around 50%. If the humidity level drops below 40%, the leaves will start to turn brown and curl. If the humidity level rises above 60%, the leaves will start to yellow.
The fertilizer, usually the plant 's native soil amended with some organic matter such as well-rotted manure, should be applied at the rate of 1/2 pound per square foot of planting area. Apply it evenly over the entire root zone and work it in to a depth of 8 to 10 inches.
Pruning a fringe tree is best done in late winter or early spring before new growth begins. You can remove up to one-third of the tree's branches, but no more. Cut branches back to a bud or lateral branch, and make your cuts at a 45-degree angle.
Propagation of the fringe tree is typically done via rooting of hardwood cuttings taken from the tips of new growth. The cuttings should be taken in late winter or early spring before new leaves begin to open. The cuttings should be about 6-8 inches long and should have at least 2-3 leaf buds. Cuttings should be placed in a moist, well-drained rooting medium and kept under mist until roots begin to form. Once roots have formed, the new plants can be transplanted to individual pots or into the landscape.
Usually, the plant growth rate is determined by soil type. They generally prefer moist, well-drained soils, but can also tolerate periods of drought. Their roots are deep and strong, allowing them to anchor themselves in a variety of soil types. In general, they have a relatively slow growth rate, but this can vary depending on the specific tree species.
Common problems for this kind of plant are powdery mildew, leaf spot, and root rot. For powdery mildew, try using a fungicide. For leaf spot, remove the affected leaves and dispose of them. For root rot, try using a fungicide or root stimulator.
