Aphid removal near harvest.

Mate, in addition to weed, I biologically grow dozens of roses and clematis and over the years I have learned that nettle macerate sprayed on roses is very effective against aphids. If you can't do it at home, you can buy it ready, it doesn't alter the flavor (at least the homemade one). For small infestations I personally quickly pass the flame of the lighter on the aphid columns, simple, fast, effective and harmless for the stems. Try it. They will die in a second.

Azadiractin is not very systematic so I dont think it will help much. I suggest a folair spray or lace wing larva.

sprinkle ground cinnamon around your plant to keep those ants away!👊
