What Tips Should You Need to Reduce the Impact of Heat Stress on Trees? 
                     How to Recognize Your Trees Are
Experiencing Heat Stress?
Heatwave is bad not only for humans but trees also. The hot temperature does
more harm to young and old trees than other trees. If you have planted trees in
your  Sacramento landscape design,  make sure your trees are well  protected
from this  kind  of  damage.  Heat  stress  negatively  impacts  trees.  It  affects  their
appearance  and  makes  them more  inclined  to  catch  diseases  and  other  insect
problems.  
During hot temperatures, trees find it  difficult  to stay alive, especially damaged
trees or trees with damages.  Since trees use all their energy to just survive in heat,
damaged trees have a lesser ability to heal themselves than other trees.
There are ways to reduce the impact of heat stress on your tress. For this, first, you
need to recognize the warning signs a tree is showing. 
Here are the warning signs of heat stress in trees 
Trees and plants should be looked after regularly. As soon as you recognize the
warning  signs  of  heat  stress,  you  should  get  in  contact  with  experienced tree
services  in  Sacramento for  preventing  your  trees  from  the  terrible  damage
before  it’s  too  late.  The  early  you  notice  these  signs,  the  earlier  you  can  do
something to help them. So, it’s important to act quickly in this situation. 
Heat stress or hot and dry temperature can put a dire impact on newly planted
shrubs and trees, and can even lead to their death. 
 Wilting leaves and droopy plants
 Yellow leaves or tree’s needles turning yellow. 
 Rust spots on leaves or rust-colored leaves
 The leaves are curled 
 Scorched leaves
 The plant is not achieving healthy growth.
 Trees are losing their leaves and most of the fallen leaves are yellow.
The above signs can help you identify heat stress in trees. However, it’s not easy to
recognize whether your trees have been impacted negatively by heat or drought.
For an accurate diagnosis, we recommend calling a certified tree professional or
arborist for the inspection of a tree. 
How to reduce the impact of heat stress in trees 
 
To minimize the impact of heat stress, here is what you can do. 
 Renew the mulch over the root system for protection from the intense heat. It
helps maintain the temperature inside the soil and keeps it from rising too
high.  
In case the root system has no mulch over it, add a 4-inch layer. Mulching
also reduces moisture loss from the soil.
 Give adequate water to the plants and trees. Trees need water to survive in
hot and dry conditions, or they can die and the result could be tree removal
in Sacramento. If you have a young shrub, make sure it is getting enough
water. Giving water to newly planted trees is very important since they are
more vulnerable to damage than mature trees.
 When it comes to big or larger trees, drip lines should be watered to allow the
excess water on the canopy to get to the ground.
  
 Too little water in the soil impacts your tress. Thus, you need to check the soil
moisture level. Water it if it’s dry.
