How Hot Weather Affects Plants
High temperatures don't just dry out the soil -- they can also significantly stress plants in multiple ways. As the heat rises, plants lose water rapidlty through their leaves in a process called transpiration, which can lead to wilting, leaf curling, or even scorching. Prolonged exposure to intense sunlight may cause sunburns, leaving leaves with bleached or brown patches, especially if the plant is already water-stresses. In very hot conditions, plants often slow their growth or temporarily stop producing flowers and/or fruit. The roots, too, are affected -- dry, hot soil makes it harder for them to absorb water and nutrients, putting the entire plant under stress. Understanding these effects is key to protecting your garden during the scorching summer months.
Watering Tips to Combat Heat Stress
Feel the Soil
Insert your finger 1-2 inches deep into the soil. If it's dry and crumbly, time to water. If it's moist and cool, you're good for now.
Observe the Leaves
Look for early signs of heat stress -- wilting during the day that recovers overnight means your plant is struggling.
Water Early or Late in the Day
Water between 6-10 AM or after 6 PM. Midday watering wastes water due to evaporation and may even scorch leavres if droplets magnify sunlight.
Water Deeply, Not Lightly
A slow soak encourages roots to grow deeper, which helps them access moisture even in dry conditions. Use drip irragtion or a soaker hose if possible.
Mulch Matters
Apply a layer of mulch (like shredded bark or straw) around the base of plants to keep the soil cool and moist longer.
Don't Overwater
Overwatering in heat can suffocate rots, especially in clay or compacted soil. **Always check before watering**
