Organic aphid control on fruit trees during bloom?
I'm new to the forum and hope this is the right place to post this question.
I live in MA and bought a home recently that has 2 Red Delicious, 1 Bartlett Pear and 3 Asian Pear trees. I am not a garden person, so this is very overwhelming to me. I think I'm heading in the right direction though. :)
I started spraying the trees about 2 weeks ago with a homemade mix of liquid seaweed,molasses, baking soda, apple cider vinegar,Murphy oil soap and 1 gallon water. The trees seemed to love the nourishment. All my Pear trees are in bloom, and the Apple trees are in "Tight Cluster" and "Pink Stage".
I have just noticed that there are aphids (tiny black specks?) on the leaves, and showing leaf curl from them. It's not severe yet, but enough of a concern to me. Other then that everything looks good.
My question is, is there anything I can do about it now or do I need to wait for "Petal Fall" ? I would prefer organic methods for now, chemicals if needed later. I also have some Chive Plants I can plant for companion planting.
Thanks in advance.
