Limbs are shooting out too low on my olive trees. Would it be right to
trim them up while dormant this winter, or should I let them grow
another year before doing so? I think I want the first limbs to start at
18 to 20 inches above the ground.

Take off the lower shoots whenever your knife is sharp. Do not let them
grow another year. Theoretically, the best time to remove them is toward
the end of the dormant season, but if they are not large as compared
with the whole growth of the tree, go to it any time.



Canning Olives.



What is the recipe for preserving olives by heat, and how long do they
have to remain in the heated state?

Canning olives is a process, not a recipe, and it has to be operated
with judgment. It resembles, of course, the common process of canning
other fruits and vegetables. It has been demonstrated that heating up to
175° Fahrenheit is effective to keep olives in sealed containers for
over two years. The heating was done in the jars in the usual canning
way for several minutes after 175° was reached, to be sure the contents
were heated through.
