Gardening Jargon – Heat Stress in plant

Heat stress is a period in which temperatures are hot enough to cause damage to plant function or development. Mainly it is identified by leaf drop in summer days. Other ways to find if plants are heat stressed is as follows

– Leaf curl

– Drying of Leaves and eventually shedding from plant

– Leaf Drop


Heat stressed leaves are dried and yellowish in colour. If the leaves are green and shiny then it is “root-rot” not “heat stress”.

In summer, water adequately to your containers and outdoor plants. Spread some Mulch to keep the moisture.
