Yellow new leaves / interveinal chlorosis Micronutrients may be present but unavailable because of alkaline soil, saturated roots, planting depth or water quality.
Check first Compare new and old foliage Check moisture and planting depth Note concrete, shell or fill Test affected and healthy soil separately Responsible next steps Correct drainage or planting depth first Use only a labeled, diagnosis-appropriate micronutrient product Protect hardscape from iron staining Open related guidance → Root-zone stress Shrubs & ornamentals · Palms · Trees · Turfgrass
Whole-plant yellowing Saturation, salinity, root injury or irrigation-water quality can create broad yellowing that resembles hunger.
Check first Inspect drainage and irrigation runtime Look for dark, soft or shortened roots Document construction or flooding Responsible next steps Restore oxygen and drainage Reduce irrigation only when the root zone remains wet Seek diagnosis before fertilizer or fungicide Open related guidance → Turf decline Turfgrass
