I have a pearl acacia here in northern California that has been growing in a container. The left photo is how it looked first transplanted and the right photo is one year later. I've been watering daily and it's gotten full sun in a very hot yard. I also tried leaving it without water for several days at a time. Leaves continue to turn yellow/brown and fall off. Should I transplant to a larger container? Prune? Any tips are much appreciated!
