New Hawthorne, second and third flush growth isnt as robust as first flush and tends to be droopy when its warm and sunny. It hasn’t got the cuticle fully formed.
This new growth, especially new extensions, like you are getting…in the sun, tends to transpire water faster then the water can be replaced. So watering a lot as
@RKatzin mentioned will solve the problem.
Yet I’m not around all day sometimes. So instead I move the trees into a more shaded location until the cuticle forms. About 7 days out here. imho this allows the new growth to extend faster as it isn’t constantly alternating from a fluid positive/fluid negative mode. Once the cuticle has formed, back in the sun.
See below image. Second growth extensions, cuticle almost fully formed. Pruning back, striking the cuttings, and into the sun the tree goes.
Once pruned to where you want it, the new extensions off this initial growth will push again. Repeat if needed.
I love the idea of timing by the moon phases!
Here’s the Almanacs recommended dates to prune in case you are interested. Yet it seems to me regular timing is the key factor.
In your situation, I would leave everything that grows out on the trunk for now. Get the energy positive and robust. Don’t even prune for at least four weeks or more, depending on how strong the growth is. Then prune everything back to a prospective location, but no shoot selection. Keep this going all year. In the winter select the branches you like best and keep a couple extra.
