Vine characteristics
Drought context
Plantgrape describes Merlot as not well adapted to intense drought. This source-attributed observation does not establish a soil-moisture cutoff, an irrigation amount or a comparison with GroundWorx-monitored vines.
Regional research context
NC State Extension describes Merlot as midseason harvesting with semi-upright growth in its North Carolina comparison table. That table's regional scope is retained rather than applied globally.

Sources & scope
- Plantgrape — Merlot ↗
INRAE / IFV cultivar reference. Vine-trait observations belong to this reference's context; they are not universal planting or irrigation recommendations.
- UC Davis Foundation Plant Services — Black Grapes of Bordeaux ↗
Independent institutional history used to cross-check cultivar identity and geographic context. It does not independently validate every agronomic observation in Plantgrape.
- NC State Extension — Choice of Varieties ↗
Corroborates red-wine identity and supplies the North Carolina-specific harvest and growth observations.
Cultivar descriptions are source-attributed reference material, not site prescriptions. No numeric soil-moisture threshold, disease diagnosis, regional suitability guarantee or GroundWorx performance claim is established here.
