Hello everyone!

For our 1 year anniversary in September, I bought my boyfriend a Valencia orange tree from Hirt's Gardens (love that place). It's about a foot, maybe a foot and a half tall. In the first few weeks after placing in front of a south window, it dropped about 50% of its leaves. The house is warm, usually around 70-75 (TOO warm if you ask me, but his parents are strange). It's potted in a 10" glazed clay pot with store bought Citrus soil. He waters it probably a lot less than he should, maybe once every 3-4 weeks (all of his other plants are cacti and succulents, so he thinks he can treat them the same). It's actually flowered profusely the last month or so, but all of the tiny pea-sized oranges were dropped. There seems to be new growth starting now, but the old leaves that didn't drop when he got it have weird lighter patches on them.

here is what it looked like when I repotted it for him:

and this is the only picture i have of it now:
