Hyphodontia sambuci, the elder whitewash, is a basidiomycete fungal pathogen on deadwood, especially elder. [ 1 ] It is resupinate , forming a very thin structure which is white, pruinose (flour-like dusting) or chalky in appearance.
Once the wood gets wet, floors can swell, buckle, and warp. To best preserve your hardwoods, wet mop high-traffic areas only twice a month. Areas that get less traffic can be cleaned monthly.
The forest is a natural system that can supply different products and services. Forests supply water, mitigate climate change, provide habitats for wildlife including many pollinators which are essential for sustainable food production, provide timber and fuelwood, serve as a source of non-wood forest products including food and medicine, and contribute to rural livelihoods.
In any case, desirable qualities have been identified in each particular tree, and competing trees are removed to promote the desired trees. To help distinguish between cleaning and weeding, consider these two images from the northeastern United States. Both pictures focus on an eastern white pine of good future sawlog

Pollarding tends to make trees live longer by maintaining them in a partially juvenile state and by reducing the weight and windage of the top part of the tree. [6] Older pollards often become hollow, so it can be difficult to determine age accurately. Pollards tend to grow slowly, with denser growth-rings in the years immediately after cutting.
Both summer sunburn and winter sun scald can cause the tree's bark to crack or die, resulting in additional stress which is compounded by insects and parasites that enter the barkless wood, an invasion that will ultimately shorten the tree's life. Tree paint or whitewash protects against this. [2]
The wood is dense and very hard, difficult to plane, but drills, sands and turns well. It is termite resistant. It was once used for railway sleepers and is now prized for ornamental work and furniture. It burns very slowly with intense heat, and is often used for a fire which is intended to burn all night in order to keep wild animals at bay.
