Q.Eucalyptus Trees in Wet Ground
Knowing that eucalyptus trees take up a lot of water, I was hoping that I could plant trees in areas of our yard that get standing pools for a week or so after particularly heavy rains. Would the lack of drainage kill the trees? Also, we do get down to freezing temps for short periods in winter (in southeastern PA). Are we out of luck here?
