What’s wrong with my lemon tree?
Hey,
About ⅓ of our lemon tree is producing GIANT green fruits that have very thick rinds with weird pulp (color, texture, taste). They never turn yellow, and are the size of a large grapefruit or pomelo. The leaves on that part of the tree are also different, larger and lighter in color.
The tree shares a root system at the base, but the tree splits into two distinct branches at the ground level.
The healthier side of the tree has some lemons that still have some variation in size and rind thickness, but are all yellow when ripe and taste good.
Believe it’s a meyer lemon tree as the lemons are definitely sweeter and slightly darker/more saturated than average lemons.
We first noticed a few of these massive unhealthy lemons a few years ago, but gradually as become much more. Now it is a full ⅓ of the whole tree.
For reference, in the photo with the two halves, it’s the smaller lemon that is in the other photo comparing size to the healthy lemons. The larger lemon is only shown in the halved photo. Ruler and American quarters provided in that photo for scale. We're in northern CA, plant zone 9b.
What’s wrong with that side of the tree? And what do we do about it?
Thanks in advance!
Edit: thank you all for the info and advice! I’ll go through and reply where it makes sense.
While I’m here, upon further research it looks like Meyer lemons are NOT supposed to have thorns. Our Meyer lemon part of the tree does have thorns. Could that be a result of the grafting? Is it a different varietal of lemon?
