If your arborvitae or juniper is dropping needles in June, look for small spindle-shaped bags hanging from the branches. Those are bagworm larvae actively feeding, and a single untreated tree can be defoliated within two seasons. The most reliable fix is hand-picking the bags now, before the caterpillars finish their summer feeding cycle and reproduce. … Read more
Stop deer browsing on native plants without an 8-foot fence — layered defense plan: dusk pressure test, browse-resistant native swaps, scent rotation, motion deterrents, and HOA-friendly cages.
Pull tree of heaven seedlings by hand in June before they set a taproot. Young Ailanthus altissima sprouts are easy to lift in moist soil during their first growing season, but once a taproot forms, usually within 90 days of germination, only repeated cutting or targeted herbicide works. Removing seedlings early starves the spotted lanternfly … Read more
If a colony of yellow jackets has set up under your lawn, a five-minute walk before you start the mower is what stops a hospital trip. Look for steady traffic of striped wasps slipping in and out of a single dime-sized hole, usually in dry, sunny soil along a bed edge or near a stump. … Read more
Groundhogs can be kept out of a native garden without trapping by combining a buried-L hardware-cloth fence, a cover audit at burrow entrances, and a rotating scent deterrent within the first three weeks of damage. Most defenses fail because they target jumpers; groundhogs climb and dig instead. Once the fence bends outward underground and arches … Read more
Solarizing a sunny patch of lawn from mid-June to early August will kill the grass and most surface weed seeds in six to eight weeks, leaving a soft, bare seedbed you can plant with native plugs by Labor Day. The method uses clear plastic, sun, and water. No herbicide. No digging. No sod cutter rental. … Read more
If your local native nursery is sold out of butterfly weed and Prairie Moon won’t restock until fall, the fastest legitimate sources are your state’s conservation district seedling sale, the regional chapter of Wild Ones, and a handful of small Midwest and Mid-Atlantic growers who never appear in Google’s first page. Stack three of these … Read more
Asian jumping worms (Amynthas and Metaphire species) thrash like snakes when touched, leave coffee-ground soil behind them, and can hollow out a native plant bed in a single summer. To stop them, identify adults in June or July using the mustard test, refuse any mulch or compost not heat-treated to 130 degrees Fahrenheit for three … Read more
Quick answer: Powdery mildew turns bee balm leaves chalky white starting in mid to late June when humid nights follow dry, warm days. To stop it without harming pollinators, plant resistant Monarda cultivars like ‘Marshall’s Delight’ or ‘Claire Grace’, space clumps 24 to 36 inches apart for airflow, water at the base before noon, and … Read more
Quick answer: Six native plants that survive dry shade under mature trees without supplemental water by year three are wild ginger (Asarum canadense), foamflower (Tiarella cordifolia), Christmas fern (Polystichum acrostichoides), white wood aster (Eurybia divaricata), golden ragwort (Packera aurea), and zigzag goldenrod (Solidago flexicaulis). Plant 1-quart sizes in fall, set each plant between tree roots … Read more
