aphid control on crepe myrtle
Hi, I'm new here. I've bought neem oil but it's such a mess & so little spray against so many aphids that I'm going to try the plain jetstream of water method.
Can I pour the neem oil mixture onto the ground around the crepe myrtle & kill the aphids systematically? Will it kill the aphids? Will it hurt the crepe myrtle?
To 1 gal water I'm using 2 tbsp neem oil, 1 tbsp baking soda, few drops either Dr Bonner Peppermint castile soap or Joy lemon scent non-ultra (whichever people think is best), not storing this mixture & planning for after the sun starts to set. Right formula? How often to pour around the crepe myrtle? I can post the circumferences of my 4 crepe myrtles if anyone can help me with how much to apply. Thanks!!!
