Overview
- Local outlets in Argentina published fresh guides with urgent steps to guard plants from frost during a sharp cold spell.
- Water only in daylight and only when the soil feels dry to the touch to avoid frozen roots and moisture that feeds fungi.
- Cover sensitive plants at night with fabric or frost cloth, and keep any plastic off the leaves to prevent condensation that can freeze on contact.
- Move potted plants to sheltered spots like covered patios or against sun-warmed walls because containers lose heat faster than ground soil.
- Insulate roots with dry leaves, straw, bark, or mulch, and place water-filled bottles near the base so stored daytime heat releases overnight.
