To find out the best and safest way to prune apple trees, we chatted with an expert arborist and the owner of an orchard. Both shared their tips for pruning apple trees to keep them happy and ...
In southern Germany apple and pear trees have been a part of the landscape for a long time, and are difficult to protect. The decline of apple and pear trees from their landscape can be expensive to replace and could have a negative effect on tourism. In the long-run, fire blight is a very important factor of economy and society. [citation needed]
Gymnosporangium juniperi-virginianae is a plant pathogen that causes cedar-apple rust. [1] In virtually any location where apples or crabapples and eastern red cedar (Juniperus virginiana) coexist, cedar apple rust can be a destructive or disfiguring disease on both the apples and cedars.
The extra time to cropping may be offset if new trees are planted a few years in advance of old trees finally falling over, furthermore, if the old orchard was grubbed— i.e. trees were healthy when removed, it is unlikely that replant disease would be a problem as pathogen levels may never have been high.

The first light brown apple moth to be confirmed in California by DNA analysis was found in February 2007. James Carey, a professor of entomology at the University of California-Davis, believes, based on his previous experience with the gypsy moth program and its geographic spread at the time of identification, that the light brown apple moth had likely been in California for many years before ...
Above the tree line, extreme winds preclude tree-like growth. [6]: 17 Constant winds hitting the plants limits their size and flattens their shape. [10]Small size or dwarfism is therefore an adaptive feature to the extremes, and most alpine plants are just a few inches tall.
