Espalier Conference Pear
Can anyone help please. We have a three year old espalier Conference Pear which has produced good crops of pears over the last two years but this year all the buds are now starting to fall off except for about six. It had a good show of blossom during the mild warm spell in April and we had lots of bees about to pollinate and then we had some really cold nights. We did cover with fleece except on two night when we were away and wondered if this could this be the problem? The pear is on a wall that is in full sun for most of the day. Just before the fruit buds started to fall the pear has put on an unusual amount of growth and we do not know what the cause for this is either? All the foliage is healthy. Any suggestions gratefully received.
