Thank you very much for listing some possible causes and some possible
fixes.
I live near Los Angles, CA in Panorama City, CA and summer season is
ending. Tree gets only afternoon sun. Fruit appears to be on trunk from
above the graft.
Possibilities a
1. Greening Disease: My tree leaves do have the characteristic yellow
splotches
2. Possible Zinc deficiency or not adequately acid soil.
3. Your tree might be dying of old age.
I will check for adequate moisture before watering again. Also will test
soil acidity for pH and correct with soil sulfur if less than 6.0. Will
add zinc sulfate if present food does not contain Zinc as trace element.
"IF" cause is Greening Disease, can another Dwarf Meyer Lemon be
planted in the same location? Must the soil be treated to kill Greening
in soil?
Many thanks. Dave_S

My 30 year old Dwarf Meyer Lemon tree is growing in the ground.
This year it contains at least 10 dark green golf ball size lemons that
refuse to turn yellow, remain dark green and rock hard. These tiny
lemons appeared early summer, and very slowly became golf ball size.
Trouble is, that these lemons remain same size. Only two show a tiny
yellowing section (10%) and are still dark green and hard as a rock.
The leaves also do not look green and healthy as they have in the past.
Now leaves are not bright green, but green with many alternating yellow
spots from tip and along edges to the back.
I may have not deep watered often enough, roughly did water every three
weeks. Have been infrequently feeding with Scotts Citrus food.
Want to help this tree ripen those ten stagnated lemons.
Question is what can I do to revive this Meyer Lemon?
Another 24 hour deep watering?
Apply commercial Citrus dry plant food?
Apply 0-10-10 to stimulate fruiting?
Apply steer manure?
Sure need some suggestions. I can supply pictures if needed.
Thank you, Dave_s
There was a show on PBS not long ago about a disease affecting
citrus around the world where it stays green called citrus
greening disease.
I did a Google search and there are lots of links. Unfortunately
it's all bad news. What area of the world are you in?
