    Hi Barbara –

    It depends on if you are using a copper concentrate spray or a “ready to use” variety (RTU). I would be more concerned about burning plants if you are using the concentrate, especially if there are citrus trees in your orchard. I would refrain from applying neem for at least 24 hours after liquid copper application, and would highly recommend using the RTU spray. Find exactly what you’re looking for here:

    Liquid Copper Spray

    Pure Neem

    Happy Spring!
