Q.Crabapple Tree Flowers Every Year But Sets No Fruit Ever

Zone SA17 4BS | gizmo17514 added on May 10, 2022 | Answered

HI, I have a deep crimson flowered crabapple tree that is covered with blooms every year but has never had any fruit , after flowering I can see tiny set fruit but within a short time they fall, also it seems to loose its leaves during the summer . The tree is about 12 years old and is growing in full sun and is growing about 15 – 20 feet from a large Beech tree , I was wondering if its not getting enough water because of the Beech tree and it’s growing in very free draing ground as the garden is on a gentle slope with shale underling the topsoil, thanks for any help .

Unfortunately, your photos did not come through. I am unable to assess the situation, thoroughly.

My guess could be a lack of nutrients, namely phosphorus and potassium, or it could be competition from the nearby tree roots. It could be the luck of the draw, as well. Some trees just have trouble fruiting!

Defoliation in the summer could have something to do with this, OR it could be a genuine disease. You would notice other symptoms other than defoliation, though, like spotting or rotting leaves.

Keep in mind that some trees are not self fertile, and will require a pollinator. This is less common with crabapples, but can happen.

Some are naturally fruitless, or only produce a few fruit.
