Looking at the needles themselves, you may notice brown tips or entire needle discoloration of a disease complex known as White Pine Needle Disease or WPND. Distinguish this from the normal yellow coloration and drop of the oldest needles in the fall. White Pine Needle Diseaseīrowning needles and sparse tufts of new growth often signal the first obvious symptoms of an ailing white pine. Unless a needle cast disease as described below occurs, retain the fallen needles as a natural moisture and pH buffering mulch, or provide up to 3" of mulch up to the drip line for young, planted trees. White pine tolerate neither root disturbance, street-side planting requiring heavy winter salt maintenance, nor moisture extremes. Above ground canopy space would accommodate a 50 - 100-foot future height with 20 to 40-foot of spread and plenty of sun. Avoid those factors by siting your tree to succeed from the start! Proper soils for best growth includes sandy or loamy noncompacted soils (not clay), a pH between 5.5 and 6.5, and good drainage. ![]() Environmental factors leading to white pine decline include soil and moisture conditions white pine is not adapted to growing in. The result is a decline in the overall health of the tree. White pine decline refers to a complex of environmental and biotic factors negatively influencing both short- and long-term health of the plant. Due to its susceptibility to drought, air pollution, and salt, sometimes white pine requires special siting and care in an urban environment. Stroking its leaves can activate an immune response of T-cells in the human body. One mature white pine can intercept up to 4000 gallons of rainwater per year. White pine provides both important ecosystem benefits and enhances health. A popular landscape tree used for screening (although it naturally loses its bottom branches over time) and its delicate five needled bundle of fine-textured leaves. Widely distributed (10.6% of area), and the tallest of the eastern conifers, some consider white pine the Sequoia of the East. The Pine Tree Riot of 1772, where local townspeople chased and beat the King’s mast surveyors with pine switches may have even inspired the Boston Tea Party. ![]() Surveyors for the "King's Woods" blazed the largest white pines with the "King's Broad Arrow", a series of three hatchet slices. Once demanded by the King's Royal Navy for its straight tall masts, Pinus strobus inspired the White Pine Acts of 16 and fueled colonial resistance.

Special thanks to the contributors of the open-source code that was used in this project: Elastic Search, WordNet, and note that Reverse Dictionary uses third party scripts (such as Google Analytics and advertisements) which use cookies. The definitions are sourced from the famous and open-source WordNet database, so a huge thanks to the many contributors for creating such an awesome free resource. In case you didn't notice, you can click on words in the search results and you'll be presented with the definition of that word (if available). For those interested, I also developed Describing Words which helps you find adjectives and interesting descriptors for things (e.g. So this project, Reverse Dictionary, is meant to go hand-in-hand with Related Words to act as a word-finding and brainstorming toolset. That project is closer to a thesaurus in the sense that it returns synonyms for a word (or short phrase) query, but it also returns many broadly related words that aren't included in thesauri. I made this tool after working on Related Words which is a very similar tool, except it uses a bunch of algorithms and multiple databases to find similar words to a search query. So in a sense, this tool is a "search engine for words", or a sentence to word converter. It acts a lot like a thesaurus except that it allows you to search with a definition, rather than a single word. The engine has indexed several million definitions so far, and at this stage it's starting to give consistently good results (though it may return weird results sometimes). For example, if you type something like "longing for a time in the past", then the engine will return "nostalgia". It simply looks through tonnes of dictionary definitions and grabs the ones that most closely match your search query. The way Reverse Dictionary works is pretty simple. ![]()
