Drive bye. Just my two cents but I know the plants are young and you have enough room for a monster that's for sure............... I seen that second dripper hose you installed, But soon make sure you water till every inch of soil is wet and the roots will spread out. I've learned in the past 35 years that plants will grow to allotted space as long as there is moisture out there for them to reach for. And the larger the root ball,,,, larger the plant.
