Container Apple Tree

helenjfitch

I'm looking for help with a container grown apple tree.  It was doing very well, blossomed nicely and set fruit.  Now the leaves are dry and the fruit is withering.  It's been well watered and other apple trees in the garden are thriving.  I did use compost that had had potatoes in and some of those have grown.  I've pulled up the aerial parts but I'm reluctant to dig and further disturb the tree.  There are a couple of strawberry plants in there too that are doing fine.

Any suggestions as to what the problem might be.

Thanks

Could you post some pictures?  Both the tree whole, as well as detailed images of the leaves and fruit.  What size pot is it in?  Describe your watering too.. how much how often?

What sort of compost ... if it was ordinary multi-purpose then I'm afraid it's not suitable for a tree.  Also if it was used for a previous crop all the nutrition will have been used up.  Was it replenished with fertiliser?

What size container is it in?  

What's the feeding regime?

As requested, photos of the tree both as a whole and with close ups.  The final photo is of the other apple tree in identical container with the same compost mix, feed and water.  Planted at the same time 

The compost was a mix of well rotted manure, garden compost and as mentioned, some compost from potato bags to make up bulk.  You can see that the strawberry plants are doing well and the other tree is thriving and healthy. 

I feed them my home made comfrey feed, watered down, probably once a week. All the fruit and roses get it, everything else looks fab apart from this one poor tree.

Possibly Fireblight ?
