Reliable sources for disease-resistant stock

I’m lining up spring installs in Zone 6b and want wholesalers with a proven track record on disease-resistant cultivars (think boxwood blight–tolerant selections and Cercospora-resistant crape myrtles) plus clean, inspected liners. If you’ve had consistent, healthy deliveries the last two seasons, who do you trust in the Mid-Atlantic, and do they share their sanitation protocol or certification? A pointer to any cultivar lists by disease resistance you use in bids would be great.

Been solid with Saunders Brothers (VA) the last two seasons — NewGen ‘Freedom’/‘Independence’ boxwood came in clean with tagged inspections, and they share their blight sanitation here: https://www.saundersbrothers.com/newgen. For crapes, Overdevest (NJ) and Manor View (MD) have been reliable on tolerant picks like ‘Natchez’ and ‘Acoma’; small caveat: always “ask for their latest inspection report” and book early. Not glamorous, but a nursery that shows you footbath and tool-disinfection logs usually ships like a kitchen that labels every spice.

Adding to @mjohnson83, Lancaster Farms (VA) has been solid for me the last two seasons — Cercospora-tolerant First Editions ‘Plum Magic’ and clean NewGen liners arrived with VA/MD inspection tags, and they’ll share their sanitation steps if you ask (https://www.lancasterfarms.com). Only caveat: spring rush bumps lead times, so pre-book and request ‘latest sanitation protocol’ in writing.

Pleasant Run (NJ) sent ‘Tonto’ crapes and NewGen with state phyto tags and ‘clean, inspected liners’ paperwork; spring sells out…
