What does a diseased lemon tree look like?

What's wrong with my lemon tree leaves?
Most likely cause: Leaf Curl
Citrus leaves can curl when temperatures are cold or extremely hot, some insect infestations such as scale, mealy bug, mites or aphids will cause leaves to curl. Over-watering can also cause this. Other times it is leaf curl disease. Leaf curl overwinters in buds of infected trees.

Is vinegar good for lemon trees?
The best solutions are to encourage a thriving, healthy soil ecosystem that will naturally improve pH, or to provide acidity to soil by mulching with face-down cut halves of waste citrus, watering with diluted vinegar at proportions of about 1/4 to 1/2 cup of white vinegar in 2 gallons of water, or using an acidifying ...

How do you revive a dying lemon tree?
If you suspect your citrus or lemon tree branches are dying because the plant is in a shady, swampy location, you may be able to rescue it by transplanting it to a raised bed with full-sun and humus-rich soil. However, transplant shock may kill the plant too, especially if it's already stressed.
What can I spray my lemon tree with?
Use about a cup of ordinary cooking oil, a half a cup of water and a tiny amount of ordinary washing-up detergent. This is known as white oil. Put it in water, so it's about 40 parts water to one of this mixture. Stir it up and spray it on.
Is human urine good for lemon trees?
We know that urine can do a plant good. Certain plants (like citrus trees) will absolutely do well if you add urine to their intake. But urine is very high in nitrogen and could potentially "burn" the plant.
How often should lemon trees be watered?
With ground-planted citrus trees, watering should happen about once a week, whether from rainfall or manually. Be sure the area has excellent drainage and that you soak the ground deeply at each watering. If the drainage is poor, the tree will get too much water.
Is Epsom salts good for lemon trees?
