Why does my lemon tree have brown spots and is dropping g...
I’ve had this tree for about 2 years and it has recently shown these brown spots that seem to grow. It has dropped some of them, but more keep appearing. It once dropped a brand new leaf the moment it developed a tiny spot. It has never produced fruit or flower. It has normal soil. I’ve only moved it pots once and I gave it 10-10-10 grainy fertilizer when I moved it to a new pot. I put some rocks near the drainage hole. It had the problem before I moved it. I put a rusted piece of metal in the soil. It faces the south and I moved it once to the north side of my house and it developed white sploshes. I checked its roots and they’re cream and strong. New roots are pure white. I did move, but one small spot was there before I moved. I water it once I see a bit of dry soil and don’t stop watering until the water seeps out. The temperature is around the high 40s to low 50s at night and around the 70s in the daytime. It will get colder upcoming Tuesday though. What is wrong with it?

For your lemon tree, the brown spots and leaf drop you’re experiencing could be related to several factors. Citrus trees, like lemons, are sensitive to both overwatering and underwatering. Even though you’re watering correctly, it’s important to check the drainage of the soil to ensure it’s not sitting in water, as excess moisture can cause root rot or fungal issues leading to leaf spots. The temperature fluctuations you mentioned, particularly the cooler nights, can also stress the plant. Try keeping it in a more stable temperature environment if possible.
Since your lemon tree has not flowered or fruited yet, it could indicate a need for more nutrients. While you’re using a 10-10-10 fertilizer, make sure to apply it in the correct amounts, as over-fertilizing can cause salt build-up, leading to root burn or nutrient lock, both of which could result in leaf spots and drop. Lastly, ensure the plant is getting adequate sunlight, as citrus trees require a lot of light to stay healthy and productive
