I have a Citrus tree in my back garden.
Its bearing fruit now but only in one branch section while rest of tree is without any fruit.
Refer to pictures.
Kindly advise a remedy as I would like to see the whole tree bearing fruit.
Thanks in advance for your attention & care.

Ensure the fruiting season of your variety. Ensure that there is an adequate number of pollinators and no lack of or too much nutrition and water. Wide temperature swings can also cause infant fruit to fall off.

Looking at your second photo, Your tree splits very close to the ground. I'm going to take a guess all the fruit is on the trunk to the right and the leaning trunk to the left has no fruit.

Can you take photos of the leaves and branches on both those major trunks? How does the fruit taste? Is it what you think it should be? How old is the tree? I suspect one of the trunks is a sucker.

@AY100002 Was your tree purchased as a scion grafted to understock or grown from a pip (seed) or cutting?

How long ago did you plant the tree out?

Has the whole tree ever bloomed/fruited? Are all the leaves the same?

Hello,
Thanks to member who made few suggestions on the reported concern.
I will appreciate if other members could still advise their suggestions as I want to see this tree bearing fruit.

More information from you would help.

Hello
Refer to attached pictures. Pic-1 shows the split. The stem on left doesnt have any fruit and is shown in Pic-2 & 3 with leaves but no fruit.
Pic-4 shows the right hand stem with multiple branches, one is with lots of fruit as seen in Pic-4 & Pic-5. The other branches in Pic-6 have very few fruits.
Hope it gives you better insight.

The mystery deepens...

It certainly does...

@AY100002 Did you purchased the tree already grafted to rootstock or was it grown from a pip (seed) or a cutting?

How long ago did you plant the tree out?

Al

Thank you for more photos.

Do you know what kind of citrus it is? How does the fruit taste? Is it what you think it should be?

Can you pick a couple entire leaves off each side of the tree, place them flat and take photos of them?

Do you know if the tree was seed/cutting grown or grafted?

Do you know if the other, non-bearing side has ever produced fruit?

Do you know how old the tree is? How many years has the one side been producing fruit?

The new pictures are a help, but as Lucy and Al point out, the more information you can provide the more likely someone will find a solution.

Hello to all,
I must express my gratitude to people who have taken time to comment and make suggestions about my reported problem.
I will try to answer the questions posted in the forum.
The Kinnow orange is a hybrid citrus fruit developed by the University of California, Riverside in 1924.
I dont know when the tree was planted in my back garden but it must have been 10-12 ago.
The tree used to produce so much Kinno till three years ago, it would require dozens to cartons to store them. The fruit is full of juice and taste excellent.
My gardener told me that three years ago when he fed organic fertilizer to this tree, he felt after few weeks the tree was in trouble. On advice of a local horticulturalist, he digup few feet around the stem and removed the fertilizer.
The tree recovered that its grew new leaves etc but one side stopped bearing fruit.
Though I am not much of a garden person since I have been associated with a Fortune 500 company as IT consultant for major banks in the region. I definitely would like to see this tree bearing fruit again.
Thank you for all your attention & support.

I have isolated the ground as a sweet oranges tree close to Kinno is doing very well.
Whats the logic to get leaves from bearing & nonbearing Kinno branches and send you pictures.

How can I change the DP of my account?
Thanks.

That's a lot of really good information. Thank you.

My first thought was you had a sucker from the roots. If that was the case, the leaves on the sucker would look different. I have a Kinnow mandarin (its my favorite citrus) - your tree looks exactly like a Kinno. Don't bother taking leaf photos.

With your added details and history, i have a couple thoughts but proving them will take a year. I suspect a combination of:

1. A nutrient problem. Your gardener used the wrong fertilizer, removed it and didn't use anything else? Has your tree been fertilized in the last 3 years? You should be using citrus specific fertilizer every other month while the trees are in active growth. Citrus are heavy feeders and also really picky about what they require.

2. Root damage. Citrus have a shallow root system that's easily damaged by digging near it. Your gardener may have damaged the root system (more on one side of the tree than the other) and the tree is still recovering. What do you mean when you say you have isolated the ground between this tree and the sweet orange? Is that tree on the not producing fruit side of this tree? You may be continuing to damage the roots.

Insufficient fertilizer combined with damaged roots could easily cause parts of a tree to stop producing and even die. Even with proper fertilizer, if there aren't enough roots to absorb nutrients and water, its going to do poorly. Only time will tell... but in the mean time use the right fertilzer (next spring when new leaves start to grow) but use at about half the recommended rate until you see improvement in the overall tree health.

I think your tree may actually be two fused trees (the fork you pictured) each with a separate root system; that would help explain how the two parts can behave so differently. Can we assume the fruitless part also did not bloom this year? All the leaves look healthy. The proximity of the wall and walk could compromise the root system on that side, but I would expect the leaves would reflect the issue too. I am still stumped.

Thanks Lucy & Porkpal for your pertinent suggestions.
Here is my response.
1. He used another organic fertilizer which is usually used by people having same trees. He has used it once a year since 2020.
2. Logically I tend to agree with your observation that roots were damaged in earlier exercise. Now the issue seems to be no fruit on one side with plenty of healthy leaves. May be we should wait till next Kinno flowering season if tree has fully recovered.
My comment about soil has been isolated is in the context of P/H value. A sweet Orange tree growing next to Kinno is doing ok, with plenty of fruits.
3. Will follow your advise, hope the tree will come out of its hibernation.
Thanks everybody for your valuable suggestions & comments.
