Overview

• The UK is experiencing sustained heatwave conditions with highs of up to 34 C this weekend.
• David Denyer of Eflorist warns that hydrangeas, peonies, begonias and roses are particularly prone to wilting and leaf scorch under extreme heat.
• Deep watering at the base of plants before 9 am or after 7 pm is critical to ensure moisture penetrates roots without being lost to midday sun.
• Shading vulnerable pots and clustering containers under trees or behind taller foliage reduces evaporation and helps maintain cooler, moister soil.
• Cut blooms should be moved indoors, recut at a 45-degree angle and placed in fresh, cool water with flower food or a homemade sugar-lemon solution changed daily.
