Book of Joel Chapter 1 Vs. 12

 An Invasion of Locusts

all the trees... The picture was bleak, for even the deep roots of the trees could not withstand the torturous treatment administered by the locusts, especially when accompanied by an extended drought.

because Joy is... This is speaking of a time, when the joy of the people has withered away. None of the fruit trees produce. There is a curse upon the fruit and vegetables, as well as on the people. The judgment of God has fallen upon them. There is no fruit on the vine.

All of the above trees have symbolized God's people at some time, when the blessings of God was upon them. The trees with no fruit, also, symbolize the fact that God has taken His blessings away.

is withered away... Human joy and delight had departed from all segments of society; none had escaped the grasp of the locusts. The joy that normally accompanied the time of harvest had been replaced with despair.
