Why is my pomegranate fruit split?
There are a couple of very common reasons for split pomegranate fruit on a well-cared for tree. In fact, one of them may be caused by a tree getting a little too much care. Fungal pathogens are notoriously frustrating causes of split fruit. In fact, they often strike just as the fruit is ripening.
Why do pomegranates crack open when they ripen?
Excessive irrigation during the ripening period is likely to cause the fruit to crack open. Pomegranates usually begin to bear fruit in their third year. Because flowering and fruiting occurs on the tips of new branches, any form of pruning is actually a hindrance to fruit production. It is only necessary to remove dead or diseased wood,...
Does copper fungicide cause pomegranate fruit split?
However, if you apply copper fungicide to your plant next season as the fruits are just starting to grow, you may be able to kill off the fungal spores before they infiltrate your fruits and cause more pomegranate fruit split problems. The other main cause of splitting pomegranate fruit is the same as with many other fruits: irregular watering.
Why do pomegranates need to be harvested immediately?
They should be harvested immediately to prevent the fruit from becoming overripe, which can lead to cracking. Pomegranates are traditionally eaten fresh, though the process of removing the small bits of seedy fruit is time consuming. They may also be pressed to make juice, which can be consumed fresh or used in jellies, sauces and baking.

Why do my pomegranates split open?
If a dry spell (no rain or no watering) is followed by a sudden influx of water, the cells inside the fruit expand faster than the skin cells. Because the skin cells don't expand as rapidly, they get pulled apart, resulting in the split.
How do you stop fruit cracking in pomegranates?
However, for management of fruit cracking, several horticultural practices like spraying of growth promoters, micronutrients, antitranspirants, and regular irrigation with drip and mulching have been recommended (Waskar, 2006. 2006. Pomegranate (Punica granatum L.), p. 375–394.
Are split pomegranates safe to eat?

How do you control fruit cracking?
Spray treatments of potassium fertilizer, calcium fertilizer, and boron fertilizer to significantly decrease the creasing fruit. Apply potassium during the early fruit development to promote fruit peel development, increase peel thickness, enhance fruit cracking resistance ability and reduce pre-harvest fruit cracking.
What causes fruit cracking?
Several factors have an effect on fruit cracking. This can range from splitting to skin russeting. Water uptake, humidity, temperature and soluble solids (sugars) as well as calcium nutrition and standing water on the fruit are thought to have roles in fruit cracking, along with genetics.

Which is the major problem in pomegranate cultivation in high humidity rainfall area?
At any rate, in the autumn, during the pomegranate ripening phase, high atmospheric humidity causes significant economic damage because it results in cracking of the fruits.

How can I help a pomegranate tree?

After we had the first real rain this month, I saw that some of the fruits from the pomegranate tree cracked. The plan was to keep them on the tree till December so that we will have an abundance of red color in the kitchen. But I guess we'll just have to eat some of them sooner. :)

What pomegranate is more susceptible to cracking?
"Francis" and "Wonderful" are two types that are considered resistant to cracking, while "King" and "Mollar" are more prone to cracking. "Wonderful" is a common commercial variety and is particularly juicy. The cultivar "Nana" grows only 3 feet tall with 2-inch fruits. "Eversweet" has much sweeter juice than most varieties; the juice of "Eversweet" is also non-staining, unlike other types that cause a permanent red stain. "Granada" ripens one month earlier than "Wonderful" and is considered an extremely cold-hardy variety.
When are pomegranates ripe?
Pomegranates are not ripe until the fruit is entirely red. According to Purdue University, perfectly ripe fruit makes a metallic sound when it is tapped. They should be harvested immediately to prevent the fruit from becoming overripe, which can lead to cracking. Pomegranates are traditionally eaten fresh, though the process of removing the small bits of seedy fruit is time consuming. They may also be pressed to make juice, which can be consumed fresh or used in jellies, sauces and baking. The syrup made from pomegranate juice is known as grenadine. In the landscape, the large red flowers and compact shape of pomegranates make it an attractive specimen or hedge plant.
What is a pomegranate?
Pomegranates (Punica granatum) are the fruit of a large deciduous shrub of Mediterranean origin. They can be grown in U.S. Department of Agriculture plant hardiness zones 7 through 11, though they are easily grown in containers and brought indoors for the winter in colder climates. The fruit ripens in fall and must be picked before it cracks, which indicates that it is overripe. This is especially likely if rainfall occurs during the harvest period.
Do pomegranates crack?
The tendency for pomegranates to crack also varies among cultivars. "Francis" and "Wonderful" are two types that are considered resistant to cracking, while "King" and "Mollar" are more prone to cracking. "Wonderful" is a common commercial variety and is particularly juicy. The cultivar "Nana" grows only 3 feet tall with 2-inch fruits. "Eversweet" has much sweeter juice than most varieties; the juice of "Eversweet" is also non-staining, unlike other types that cause a permanent red stain. "Granada" ripens one month earlier than "Wonderful" and is considered an extremely cold-hardy variety.
Do pomegranates grow in humid climates?
The shrubs often grow well in humid climates, but with less fruit production. The fruit is also more prone to cracking in humid climates. Cultural practices that diminish the influence of excess moisture can be employed to help limit this problem. In particular, it is helpful to locate plantings where they will benefit from good air flow and to avoid planting pomegranates in very wet or low-lying sites. Mature shrubs can tolerate temperatures as low as 12 degrees Fahrenheit, though young or potted plants are less cold-hardy.
Why do pomegranates split?
Some growers recommend supplementing the soil with boron, but the commonest reasons they split are 1) fungal infection and 2) incorrect watering.
Why do my fruit trees split?
Fungal infection sometimes shows itself on the tree with spots on leaves and some leaf loss, but it tends to affect the fruits primarily, causing fruit split. By far the biggest cause though, and one you can certainly do something about, is number 2, poor watering regime.
