So a few weeks ago the weather started to get nice and warm and I put out my little acacia acuminata in what I thought was partially shaded sunlight and into a new pot with a two-layer soil pattern (loamy lower layer, sandy/rocky upper layer). Sadly, the plant's little leaves have curled up and mostly fallen off due to the too-intense sunlight. However, there are some longer leaf-life pieces (these were the "stems" holding the baby leaves) that are still quite verdent.
The plant was about 5 months old and 6" long (grown indoors in winter in a small container) when I transferred it to the larger pot, with little green stems supporting clusters of small leaves. The stems are still green after the sun trauma, and the tree itself seems perky and upright.
I can't post photos right now (new computer, yet to set up jmtpfs or w/e for my phone), but I was wondering if these longer, needle-like structures are actual foliage that can sustain the plant.
What other things can/should I do to improve the rate of recovery? Should I give it a small humidity dome? Should I give it any fertilizer (if so, what ratio, etc).
I look forward to your feedback on this.
