Pruning Pomegranates is easy!
As a first year Master Gardener, I am learning fruit tree pruning hands-on for the first time. When it came to pruning my pomegranates, I had to dig a little deeper than my Master Gardener Handbook for information. So while I was doing my research, I thought it would be a good idea to type it up and share it on ourblog. I took before and after shots of my two year old pomegranate that I pruned for the first time.
Did I do it right? You be the judge.
You will prune your pomegranate to remove tree parts that bear poor quality fruit, to encourage fruit production, and to allow good light penetration. You might also prune your pomegranate to maintain a certain shape for aesthetics or height for easy harvesting. Some people shape their pomegranates like a tree while others use pomegranates like a hedge. Like with any fruit tree, you need to remove dead and damaged wood annually. Pomegranates have thorns, so you will want to wear gloves and long sleeves to protect your skin.
Naturally, pomegranates are a multi-trunk shrub. However, they can be pruned into a single or mult-trunk tree. Either way, the number of trunks should be limited from three to six, otherwise fruit production may suffer. I left four on mine. Pruning your pomegranate into a tree form can mean risking fruit production if you live in an area that freezes like we do. So for high desert areas inInyo and Mono counties, a shrub form works best. Pomegranates form fruit on second year wood, so be careful not to prune too much or you may end up with no fruit.
After planting, cut the pomegranate to 60-75 cm (24 to 30 in). In the first year after planting your pomegranate, you should remove suckers from the roots and trunks after your primary 3-6 trunks are established. Continue this practice at least annually or as they arise.
After the first year, you will prune your pomegranate during dormancy after the risk of frost has passed but before full bloom in the spring. In late dormancy of the year following planting, prune the branches by 1/3, remove crossing branches, and leave 3-5 shoots per branch.
After the third year, you will only need to prune your pomegranates lightly each year to encourage fruit production. Pruning your pomegranate heavily will reduce fruit production but you will want to prune heavily after a year with little growth in order to re-invigorate your pomegranate. If you have a year with little or no crop, prune lightly. You will want to prune more heavily on the tops because this is where the vegetative growth occurs. Open up the middle of the plant to allow light and air to reach the blooms, which will increase fruit set. Thinning shoots on the end of the branches will increase fruit size and quality on the remaining shoots.
So there you have it. Pruning a pomegranate takes less time and makes less of a mess than peeling and eating a pomegranate. Good luck!
