The biggest decision when planning a pond is the one you want to spend the most time thinking about: where to put it? Obviously, changing your mind and redigging a big hole in your yard isn’t fun for anybody, but there are other things to consider besides aesthetics.
So you picked your spot, bought your supplies, and made sure there’s nothing but dirt under your feet. Great! Start digging, donkey. It’s a lot of work and monotonous. It’s good exercise and rewarding because you’re digging for a worthwhile goal. Just take your time and don’t forget a good pair of work gloves, otherwise it’s blister city.
The whole project took two weekends. Vegetation was left around the pond to grow out and a couple of plants were added in the pond to make it look a little more natural.
