Hi, we just moved in a house where we have a olive tree in the front
lawn. It does look good. The leaf is yellow and falling. People told
me that olive and lawn should not be together because olive do not
live water but lawn does. They said my tree is dying. Is there any way
we can save the tree. I am in California.
Perhaps the olive tree is suffering from some sort of blight or other
disease. I have a flowering crabapple tree that suffered from fire
blight. It was fine in the spring, but by the middle of summer, many of
the leaves turned yellow and fell off. It was like that for the last 5
years. This spring, I sprayed the tree with Ortho Garden Disease Control
and doused the lower branches and trunk with it. Here it is late summer
and the tree is still full and has only dropped a few leaves. I plan to
give it another dose next spring.
Olive trees Olea europea need little fertilizer. Nutrition is less
important than water. Has it been getting enough? Olive trees need very
little fertilizer but can use some nitrogen and it may actually be getting
too much if the lawn is heavily fertilized.
Olive trees can be cut back and can live to 500 years. Look at the regions
where they prosper around the Mediterranean and you can see they need little
care, but they do like full sun.
