Do not give it too much water. Mine is only watered by the neighbors sprinklers. Don't water at all until spring. It should have lost its leaves by now. I left one fruit in the tree for the birds. Flowers grow on new growth.

"we have not done much but to prune it back when it got tall, and also added some drip irrigation."

I don't grow pomegranates but it seems to me you have done quite a lot. You've made two big changes to how the tree is being treated. Pomegranates produce on new wood so if you are pruning at the wrong time of the year you could be cutting off the branches which would have borne fruit. Tim, above, has dealt with the water issue.

Also notice how overly dense your tree is compared with Tim's. I would prune out from a third to a half of the branches and open the plant up. All of those suckering branches may be taking away bloom and fruit energy.

Thank you all for the advice. We removed the drip irrigation this weekend and will prune back the tree next weekend.

Will post a follow up picture after we prune it back.

Thanks Again

The drip shouldn't matter. You are pruning out the fruiting wood though, that looks like mostly old wood.

Looking closer. Cut all of the shoots coming from the base.

After pruning. As you can see, I pruned heavily. Tree is ten years old. I have space issues with this tree.

Thanks Tim, this gives us a good idea on what we should be taking off.

As said above, don't prune new wood, clear up the tree from too dense growth instead. Regarding water, in my experience, pomegranates benefit from a modest amount of drip irrigation during the summer in California-type climate. However, no need to water them during the winter.

pruning, and care of POM trees.

I like Tim's tree shape....but, some folks like to let poms grow as a large shrub. Your call...

How often do your fertlize? You should fertilize twice a year, once in the fall after the fruit is harvested and again in the spring before it starts to flower. I followed that schedule last year and got over a dozen poms this year.

We will fertilize again on the spring. We normally use a generic fruit tree fertilizer. Here is the picture of the tree after we cleaned it up.

Brian, you did a fantastic job on pruning this tree! One more suggestion for spring care is to put a thick layer of mulch around the tree — this will save a lot of water and keep roots cooler during the summer.

@Brian, its been over a year now and we are in the Spring, how is she looking? Flowers? Please update with some nice pics.

Hit the bottom with a mixture of compost, worm castings, and azomite rock dust. Then water in and mulch over it. Repeat this process 2-3 time annually to build the soil and you'll have a healthy fruit tree.

Really appreciate some expert advise on my tree. It has fruits twice & all fruit fell off
