Summary The herbicide active ingredients used on woody plants are mainly glyphosate, triclopyr, and imazapyr, and the method matters more than the product. Cut-stump application, where herbicide goes onto a freshly cut surface, is the most effective and the most contained. In New Orleans, a high water table and pumped drainage mean soil-applied products can… Continue reading What Chemicals Kill Trees? A Guide for New Orleans, LA Homeowners

Summary Nothing kills a standing tree quickly. Girdling and cut-stump treatment are the effective methods, and both take months to a full season. In New Orleans the bigger issue is what killing a tree in place leaves behind: a dead, decaying tree standing through hurricane season, which is far more dangerous than the live tree… Continue reading How to Kill a Tree Quickly in New Orleans, LA

Summary The reliable non-chemical way to kill tree roots is to remove the food supply: cut the tree, then grind the stump and major roots, and cut off every sprout that appears until the root reserves are exhausted. Smothering and repeated cutting work but take one to three growing seasons. In New Orleans, salt-based methods… Continue reading Natural Ways to Kill Tree Roots Without Chemicals in New Orleans, LA

Summary Most trees that die in New Orleans are killed by conditions at the root zone rather than by pests or disease.

Big Easy… Continue reading What Kills Trees Permanently? Common Causes in New Orleans, LA

Summary Soil preparation starts with a test, then drainage, then structure, and only after that with nutrients.

The LSU AgCenter provides soil testing for Louisiana residents, which takes the guesswork out of what… Continue reading How to Prepare Soil for Planting in New Orleans, LA

Summary Collect acorns in fall, discard any that float in water, and plant them about an inch deep soon after gathering. Live oak acorns germinate quickly after falling in warm, moist conditions and generally do not need the cold stratification period that guides written for northern oaks describe. In New Orleans, the harder part is… Continue reading How to Grow a Tree From an Acorn in New Orleans, LA

Summary Tree roots absorb water and dissolved nutrients through fine root hairs, anchor the tree, and store energy, and they need oxygen from soil air to do any of it. That last requirement is what makes New Orleans difficult. Saturated clay soil holds almost no oxygen, so roots sitting in waterlogged ground suffocate even while… Continue reading How Tree Roots Work in New Orleans, LA Soil

Summary Plant a tree so the root flare, the point where the trunk widens into the first structural roots, sits at or slightly above the surrounding soil line. Nursery stock is frequently potted with excess soil covering the flare, so the correct depth is measured from the flare rather than from the top of the… Continue reading How Deep Should You Plant a Tree in New Orleans, LA?

Summary Set a tree back from a fence by at least half its mature canopy spread, which means roughly 8 to 12 feet for small ornamentals and 25 feet or more for large shade trees. On the narrow lots common across New Orleans, that math usually rules out large species along a side fence. Louisiana… Continue reading How Close to a Fence Can You Plant a Tree in New Orleans, LA?

Summary Replanting increases biodiversity only when the trees planted are species local wildlife can actually use. Around New Orleans, native oaks and cypress support far more insect and bird life than ornamental imports, and the region’s biggest biodiversity problem is Chinese tallow, an established invasive that crowds out native growth. Big Easy Tree Removal helps… Continue reading How Reforestation Restores Biodiversity Around New Orleans, LA
