    You need to inject and spray at the same time.

    Tbh September isn't the best time for starting, July would have been better.

    You can just use an ordinary syringe and a toothpick to make a hole in the stem.

    Injection kits from memory are in the €100-€200 range I think.

    When you have injected you need to spray the underside of the leaves.
