Dwarf Fruit Trees in Pots

[shambayango]

Hi,

I have 3 dwarf fruit trees - apple, pear and appricot in large pots, about 21/2 feet tall. Do I still have to wrap the trunks with the sticky grease tape to prevent the wingless winter moth from laying her eggs?

Personally, I wouldn't worry about it - especially as it's unsightly. Fruit trees usually produce more than enough blossoms to set a good crop (I'd guess that most seasons, fewer than 1 in 10 flowers gets to form into a fruit, so there are plenty of spare flowers!). It won't matter if you lose some flowers to the caterpillars. You can always pick them off by hand before they cause much damage. You might not even have many winter moths in your area.
