Don't Squeeze the Frog! A couple of years ago, I decided to create a pond and a waterfall in my back yard. In addition to giving me something to do outdoors in my retirement years, it provided me another way to artfully use some rocks that littered the surface of my lot in great profusion.

Over the winter, I began reading about making ponds and waterfalls. Visions of rocks started dancing in my head about the middle of February. I drew and redrew my plans. With my wife looking over my shoulder (no doubt contemplating the rocks in my head), I proceeded to lay out an ambitious rock project.

As the snow melted in late March, I was out on the slope in back of the garage with string and stakes, laying out the watercourse of the waterfall. I bought the necessary materials for the pool, water system, and electrical power for the pump. Then I waited a month for the ground to thaw.

Following the expert directions I found in books, I started from the lowest point. I set the preformed pond in place and backfilled around the upper perimeter. I left the lower side open and built a structure to contain the electrical supply.

A water feature in the yard undergoes constant transition. Now that warmer weather has arrived this season, I've realized I need to change the liner on the waterfall and move more rocks to improve the flow of the water.

Once I've completed the structural work, I'll add plantings to the fringes of the watercourse: astilbe and daylilies around the pond, sedum and vinca hugging the rocks along the watercourse, creeping thyme and alyssum emerging from the crevices between the rocks. As the season progresses, I'll add lights and potted moon-flower vines for night viewing.

In addition to keeping me occupied, the pond has become a center of gravity for my 15 grandchildren, ages 2 to 20, when they visit. Some of them go straight to the pond before they come into the house. Others come in the front door and briefly sit in front of the television set. But soon they become restless and exit at the back of the house, pausing briefly on the deck to observe the pond and waterfall from on high. Then quickly, they leave their vantage point and follow the waterfall to the pond.

I've provided a bench at the bottom of the slope next to the pond from which they can amuse themselves. Some merely sit and watch the resident frog (he's returned this spring). Others reach into the pond's cool reservoir and hum a quiet tune. The more active ones want to grab a stick and poke at the frog or the water lily. Occasionally, a child will insist on trying to catch the frog. Of course the frog has other ideas and takes evasive steps to avoid capture.

I've had to institute a few pond rules:

No squeezing the frog.
The frog stays at or in the pond.
Don't use sticks to abuse the frog or the pond lily.

After they've tired of the pond, I usually give the grandchildren a tour of my flower and vegetable gardens, where I encourage some supervised picking (though I insist they wash the vegetables before eating). Depending on the age of the child, I may offer to give one a ride in a cart pulled behind my garden tractor.

These activities tend to make the visits more pleasant for all of us. I think it also encourages my grandchildren to have more curiosity about the natural world outside and around their own home as well.

Finally, the care and grooming of the pond area provides me many pleasant hours doing something restorative to the soul. If I feel the need of a bit of shade, I step a few feet from the pond and sit down in the woods, find a fallen log next to a live tree and lean back. Absolutely no watches or cell phones allowed there!
