condition. I know, for this was a per¬ 
sonal experiment. 
Deep plowing, thereby breaking more 
roots than the trees can afford to lose 
when carrying a heavy top, will some¬ 
times produce Frenching. The working 
balance between root and branch is often 
upset by such a practice. 
Removing the cover crop from a grove, 
for any purpose, or failing to grow such 
a crop once a year, until the humus be¬ 
comes insufficient, will result in depleted 
vitality and bring on an attack of French¬ 
ing in connection with Melanose and 
other diseases which are always associ¬ 
ated with trees whose reserve of strength 
is at low ebb. 
In building up quickly and renewing 
the soil bacteria, use organic manures as 
well as chemical sources of food. 
Land not properly drained will cause 
Frenching and in unusually wet times 
great and permanent damage to the trees. 
Remedy: Avoid the bad practices and 
experiments suggested above. An orange 
grove is not a plaything. It is a business, 
and one that has its problems. There 
are, losses sufficient and unavoidable 
without courting new trouble. When in 
doubt, consult the Experiment Station. 
Let the State of Florida pay for the mis¬ 
takes which you hanker to make yourself.
