I have a semi-dwarf Bearss lime tree in a container. It seems vigorous and started flowering and producing fruit only a few months after I bought it.
It is producing new growth well, but I have noticed that all of the new growth looks less healthy. The larger new leaves are variegated, while the smaller/newest ones are pale green, almost yellow. Some of the new growth is misshapen too.
The container has at least 4 drainage holes which are not blocked.
I've tried:
- Watering less, in case I was over-watering. It wilted noticeably after a few days and recovered as soon as I watered it again.
- Watering consistently when the first ~2 inches of soil feel dry
- Applying a foliar spray with iron, zinc, manganese, etc.
- Applying a slow-release citrus fertilizer to the container soil.
