i would be very grateful if someone could tell me what is going on with my patio pear tree. i have had the tree for around three years. it has reached about 5ft 6", but only seems to produce flowers/fruit, on the bottom half of the tree, although the half that does not flower, still produces leaf growth. it has done this two years in a row now.
sound like you need a bigger pot, it might be pot bound
Are you pruning it properly? You need to reduce each year's new growth by about a third when it is dormant in the winter. This promotes sideshoots (spurs) on the branches which is where fruiting buds will later appear on most varieties. Have a look at the RHS advice on fruit tree pruning:
The other thing is to make sure you feed it with a feed suitable for fruit trees. General feeds will have too much Nitrogen and promote leafy growth at the expense of fruiting wood.
