I planted a morello cherry tree in autumn 2011. As expected, there was no fruit in 2012. This summer the tree fruited, but only with tiny, tart cherries. Is this normal for a 2 year old tree, and can I expect larger fruit in future years?
Sounds normal to me, Cardoon. While the tree is young you can thin out the fruit to get larger (but fewer) cherries.
Morello is the classic acid cherry, used to make cherry brandy, cherry jam and other delicious things. But not your sweet cherry as found in the greengrocer's. Far less likely to be eaten by birds, so not so necessary to net and all the more for you.
all my cherries were small this year, I blamed the weather
