Spraying Neem Oil on Roses and Magnolia Tree - May 2024

Last growing season (2023), I started to use Neem Oil to treat some pests like Sawfly Larvae on my Disneyland Roses and Magnolia Scale on our Saucer Magnolia tree in the front yard.  I fell behind on the roses and saw the foliage turn into lace over the Summer.   That's when I started a dual-treatment approach with both Neem Oil sprayed on the leaves and stems and a systemic granular insect treatment.  

This year, I'm going to try to stay ahead of things and despite not seeing any signs of Sawfly Larvae, I went ahead and sprayed the three original Disneyland Roses with Neem Oil.  The front yard Roses don't seem to have come back (sad), so I only sprayed the three on the side of the house.  I also sprayed the trunk and branches of the Saucer Magnolia.  

Below is one of the Disneyland Roses after dousing the leaves in Neem Oil.

I have this hand-pump sprayer that I've (now) decided is my Neem Oil sprayer.  I'm going to mark it with a Sharpie, so I don't put any sort of herbicide in here in the future.  This worked well for the small application on the roses and Magnolia.

And, here, below, is the Captain Jack's Neem Max concentrate that I used to make one gallon of treatment:
