Q.My New Olive Tree Leaves Are Dropping And Curling

Zone 11375 | Yangt593 added on July 31, 2022 | Answered

I got a new olive tree about 5-6feet last month. The first 2-3 weeks a lot of leaves dropped and now all leaves on the 2 brunches are curled and feels dry. I re-potted the tree in a big planter and I also gave the tree fertilizer (once about 1 cup). I now water 5 bowls of water a week ( before I water much less) and I just got a artificial light for the tree since I don’t know if this is cause by lack of sun, I place it next to window with 2-3 hr direct sunlight and 6-7 hours indirect sunlight.

There could be several possibilities.

It will, definitely, prefer some more light. The grow light will help some.

The next thing to consider will be how much nutrients the soil has. Olives can withstand less than rich soils, and drier conditions. A potting mix will have quite a lot of nutrients built in, and adding more can burn, for sure. Testing the nutrient content before feeding will be a good idea.

Moisture content is very important. They do not tolerate wet soils. Potting up should be done into a container that is only a few inches larger on all sides. Going up too large, and too fast, will leave soil that has no roots in it. This will stay wetter for longer, which risks root suffocation and rot. Letting the mix dry thoroughly down to, at least, halfway down into the container will be necessary between waterings.

Fungicides may be necessary:
