Neem oil mixture is best sprayed on your fruit trees in the evening or very early in the morning. This way, the helpful insects are not affected by the direct spraying (even though neem oil is harmless to beneficial insects).

How often do you need to spray neem oil on fruit trees?

This is a difficult question. I'm going to offer several options, and I hope that one of them will be useful to you.

You could spray every week, but then you'll need to do it in the morning when the dew is off. If you wait until the evening, you might not have enough time to get the dew off. You could spray at night. But, then you'll have to make sure that the dew isn't on the plants when you go to spray. And, if you don't spray as soon as the dew is off, you could have a cloudy night, and that will mean no good spraying.

Is it a good idea to use a timer?

I would suggest that you get a timer that you can set for 20 minutes, and set it so that it's set to start at dusk, and that it will shut off after 20 minutes. This way, you can spray when the dew is off, and you'll be ready to go when the sun comes up. It might take a couple of weeks of testing to get it just right.

Can neem oil be sprayed directly on fruit?

Neem oil is more effective in the long term, and can be used year-round. You can apply neem oil to your fruit at any time before harvesting, but it is not usually necessary.
