sorts of plants can be affected by leaf burn, particularly
during the hottest times of the year. Leaf burn on plants
looks terrible and is frustrating, but there are some easy
precautions you can take to avoid this problem.
The main cause of leaf burn is from spraying water, fertilisers
or chemicals onto plant foliage in hot sunny weather.
What happens, is the water on the leaf in the sun acts like
a magnifying glass - it intensifies the sunlight onto the
leaf, causing it to overheat & then burn. It's very
similar to using a magnifying glass to burn paper.
During hot weather, you have to water plants regularly and
you will almost certainly need to fertilise or apply garden
sprays - but how do you do this without causing leaf burn?
The solution is simple - whenever you water, fertilise or
spray chemicals, make sure it's early in the morning before
the sun gets too strong, or, do it late in the afternoon.
Never do it during the middle of the day in direct sunlight.
If for some reason you do need to water a plant in the middle
of the day, and it's in direct sunlight, then only water
the soil & don't wet the foliage.
When spraying soluble fertilisers or chemical sprays onto
plants, always follow the directions for application and
dilution rates on the packet. Overdosing chemicals can also
be a cause of leaf burn or damage.
Preventing leaf burn in the garden is as simple as that.
Remember, when watering, fertilising
or spraying chemicals, only do it early mornings or late
afternoons and always follow directions for use on packets.
Now you can sit back & enjoy a beautiful garden
