What is Oak Wilt? Oak wilt is a serious disease of oak trees, caused by the fungal pathogen Ceratocystis fagacearum, which is believed to be native. It can be spread by boring beetles or through root-to-root contact between trees.

Red and black oaks are considered highly susceptible to oak wilt and may die completely within four months of initial infection....
Take a look at any forest, and you’ll notice that different species of trees are growing in different places. Some of this is random, of course, but a lot of it comes down to microclimates.

Have you ever noticed that gardens under trees stay snowier in the spring?...
Growing Camellias Camellias usually grow best in partially shaded areas in well-drained soil. Although planting can take place at any time, fall is more favorable, as the roots have more time to establish themselves.

A generous layer of organic mulch will help retain moisture and keep down weeds. Pruning of camellia is usually not necessary but may be performed in spring for appearance....

Is Unbleaching Tree Bark Necessary? Sunscald is a common problem in home landscapes and orchards. Many tree growers paint the trunk with a latex based paint for sun bleach prevention, but where trees haven’t been treated the bark will lighten, dry and can crack.

Usually, a light color is used to help prevent sunscald, but you can use any light color for the same effect....

The roots and crowns of these plants live for many years, but the stems (called canes) only live for two years. In the first year, the canes are called primocanes. At this point, the canes are green and you will see them form fruiting buds. The buds are at the tips of the primocanes fruit in autumn, while the lower cane buds do not fruit until early the following summer....
