My Sky Pencil Japanese hollies have decided “tall, slim, elegant” actually means “leaning, sulking, and occasionally fainting.” They’re in a 12-inch-wide strip between a sun-baked concrete walk and a foundation, just far enough from a downspout to get biblical floods followed by desert vibes. Clay that compacts like pottery, pH flirting with 7.5+ from concrete leachate, and winters that turn them into green accordions under wet snow. Yellowing leaves, random dieback, a sprinkle of sooty mold from scale, and one dramatic exit I’m blaming on Phytophthora. They currently wear more ties than a corporate retreat. I’m trying to decide if I rehab these green exclamation points or replace them with something less… emotionally fragile. Looking for hard-earned wins and cautionary tales: Drainage and soil: Has anyone kept Sky Pencil alive long-term in concrete-adjacent alkaline clay? Mounded planting with pine bark fines? Trench drains/french drains? Anything that didn’t turn into an archaeological dig? Rootball surgery: Worth root-washing and cutting circling roots on Ilex crenata at planting, or is that a one-way ticket to sulk city? If you did it, how much did you prune and how did survival shake out? pH reality check: Has anyone actually shifted root-zone pH next to concrete with elemental sulfur, acidifying ferts, or pine bark over multiple seasons-and had it stick? What application schedule worked, and how did you monitor without playing chemist every weekend? Winter “corsets”: What’s the least ridiculous-looking method to keep them from splaying under snow/ice-soft ties, netting, twine lattice? Bonus points for methods that don’t trap moisture and fungus. Pests/IPM in tight spaces: For tea scale or mites, what’s your go-to that won’t fumigate the front walk-lightweight oils, timing, predators? Any cultural tricks that actually moved the needle? Pollination/berries: ‘Sky Pencil’ is female. If I add a male Ilex crenata nearby, do I get tasteful black berries or a sidewalk seed buffet? Anyone noticed berry set being minimal in urban microclimates anyway? Sanity alternatives: If I break up with these doom-sticks, best ultra-narrow replacements for alkaline clay + reflected heat + downspout mood swings? Thinking yaupon holly ‘Will Fleming’/‘Scarlet’s Peak’, juniper ‘Spartan’/‘Blue Arrow’, yew ‘Fastigiata’, or something smarter I haven’t met. Looking for 12-18 inch footprint, not a future top-heavy lawsuit. Convince me there’s a maintenance routine that doesn’t include “mulch volcano” and “annual funeral.” Evidence, photos, and success/failure postmortems appreciated. My HOA believes the cure for everything is “more mulch,” which is how we summoned the rot demon in the first place.
