In the finishing stages of constructing a 1/4 acre pond and I appreciate all the good advice here. My question is about the weeds that are growing in my freshly excavated pond. Do I try and kill the weeds before I fill the pond or let them be. Also, I fished two different pond this weekend, one was filled with moss and the other just had lush green grass growing in and around it. Do I need to plant anything for cover before I fill the pond, and how do I prevent my pond from having all that moss in it. Thanks.
