It took me a couple of years to figure out that one corner of my yard gets the longest hours of sun per day. I put a bench there and put my pines there. Study your yard and figure out where gets the most sun. You're also in San Diego so you also have to take your higher summer temperatures into account as well. I dont have that problem here.
This is very relevant information to my situation presently. I only have 3 pines that are somewhat developed as future bonsai as well as a couple dozen JBP seedlings. Optimal health in pines is the most important thing to grasp. I have a spot where the pines are that gets the most light right now. What are others doing to keep temperature down? Shade cloth? I try to not wet the needles and stay on the conservative side of pruning while I watch them develop and get a better sense for correct watering. I don't mean to derail the thread so I could ask elsewhere.
