UAE summer pushes outdoor temperatures above 45°C, and even indoor environments feel the stress. Air conditioners run longer, humidity drops, and south-facing windows intensify light on foliage. Indoor plants that thrive in winter may show brown tips, drooping leaves, or slowed growth without adjusted care.
Start by auditing window exposure. Move sensitive calatheas, ferns, and marantas back from west- and south-facing glass where afternoon sun magnifies through panes. Sheer curtains diffuse light while preserving brightness — essential in Dubai Marina and Downtown towers with floor-to-ceiling glazing.
Watering frequency often increases in summer because AC dries soil faster. However, root rot risk rises when owners water on schedule instead of checking soil moisture. Insert your finger into the top soil layer; water only when dry. Early morning watering lets plants hydrate before peak AC cycles.
Humidity supplementation helps many tropical indoor plants. Place pebble trays filled with water beneath pots (without submerging pot bases), group plants together, or mist lightly in the morning. Avoid misting at night when cooler AC temperatures prolong leaf wetness and invite fungal spots.
Fertiliser should be reduced during peak heat stress. Half-strength monthly feeding is sufficient for most indoor plants between June and September. Resume normal feeding in October when milder weather returns across the Emirates.
Watch for pests that multiply in dry indoor air — spider mites on calatheas, mealybugs on succulents brought indoors. Inspect leaf undersides weekly and isolate affected plants. A damp cloth wipe often controls early infestations without chemicals.
If leaves brown extensively despite adjustments, trim damaged foliage and reassess placement before repotting. Summer is rarely the right season for repotting in the UAE; wait until October when plants rebound energetically.
