Welcome to Workshop. It's great to have you join the community. I hope you find Workshop to be informative, inspirational and plenty of fun.
How long have you owned the property @Hummingbird? I ask because one reason the fruit can split is irregular watering. If the previous owners haven't looked after the tree by regularly watering it and mulching around the roots then it could be the cause of the problem. But you also don't want to water it too much, especially at this time of year, as that can cause fungus problems.
It should be mulched annually with rotted manure or compost @Hummingbird. Anytime should be fine. You also want to prune the tree lightly in winter to encourage new growth and remove any limbs causing crowding.
