Not sure where you are, but there are olive presses scattered throughout California. You go there with your load, and they will give you the oil (and keep the pomace as well as some of your money). An olive press is much more complex and expensive than an apple press. It will be 10 years before you are up to 30-40 lbs of olives per tree per year (and those 100 lbs will give you only 10-20 lbs of oil, which is very little. My family of three uses 30-35 lbs a year. If you do the pressing yourself, you may only get 5-10 lbs). In the intervening time, I would just eat some fresh (fresh olives fried with a drop of oil and salt are wonderful, and not bitter at all while hot), freeze some (they are great in all sorts of stews and braised meates) and cure most of them. Middle Eastern friends do the curing in their bathtub. For bigger crops, water in May through July, but withhold water later.

Thank you for the information. I just applied mulch around my shrubs, and the Sweet Olive is looking much better today. Most of the white spots have turned brown like scarring, and there are fewer spots, so it isn't spreading. We've had a lot of rain this past week, so I'll make sure it gets a good watering every week.

I've got lots and lots of osmanthus up here. I'v found that it's one of the few plants that are said to like part sun but actually love lots of sun even in Texas. They bloom best in sun and grow leafier in sun. But they live just fine even in total shade. Love this plant. The blooms are small and insignificant except for the apricot smell which waftes through the garden. It likes Texas so much that I've got 60 or so. They form the walls for my garden rooms. Believe me that you won't enjoy that many because the fragrance really does get overpowering. But they live and thrive and grow quicky with no water and plenty of sun. I see them all the time at the big box stores. Easy to root but slow to grow from a cutting.
