Bog day afternoon

Our little water feature is taking much longer to finish than planned, but then again, it will always be somewhat of a work in progress. Excavating the bog garden uncovered a water pipe, probably running from the old well to a barn or outbuilding. We left it in place, and lined the pit with black plastic, then poked a few holes in the sides for drainage. The soil stays nice and soggy without being a giant mud wallow.

It’s hard to slog in the bog when temps hit the 90’s, and the rest of Seven Trees Farm needs extra watering and weeding. Adding a small canopy definitely helps keep the jobsite cooler. The trough pond has a sun bonnet made from bamboo poles and shade cloth. Too much sun can cause algae blooms, and the water plants can’t keep up filtering the fish waste. We plan to rebuild the bonnet with timber-sized bamboo and switch to green shade cloth eventually.File Jul 26, 11 47 02 AM

The random assortment of bog plants we’ve accumulated this season are waaaay overdue to get their roots in the dirt, so in they go, and we’ll finish up the hardscaping shortly.File Jul 26, 11 48 34 AM

So far we have cardinal flowers, crocosima, green goddess calla lily, a button fern, creeping Jenny, yellow eyed grass, dwarf cattails, and some Irish moss and native sedges that we found in the yard. The little tub in the middle will be mostly filled in with dirt and pea gravel and holds more water than the rest, for plants and critters that like their toes wet. File Jul 26, 11 49 25 AMAn old pump spigot for the outflow and a small dripper over a birdbath set in the water keep things circulating. The fish love playing in the bubbles and birds & bees come and go all day, drinking and bathing. Still plenty of room for more plants in the trough 🙂

Hopefully the spaces between them will provide habitat for toads and frogs. The narrow space between bog and trough will have a little pea gravel path that is sloped to allow overflow from the pond to drain into the bog. Once the rainy season returns, that is.
It’s amazingly refreshing to sip a cold bevvie while watching fish & wildlife, listening to the bubbles & splashing. The sound of the neighbor’s mower isn’t quite drowned out, but with so much nature going on, who cares…

Getting our feet wet and hands muddy

File Apr 11, 9 50 59 AM
Starting out with a level base is critical, since the weight of the water, gravel & plants will make the dirt underneath settle.
File Apr 11, 9 51 20 AM
The trough only holds 159 gallons, so choosing plants & critters that can be kept in healthy balance is a fun challenge.
File Apr 11, 9 51 38 AM
There is just enough slope to allow water to overflow beneath the filter pan and down to the ground below. We’ll be sinking a 40 gallon tub in the ground to make a boggy area for taller plants later this season.

The pump outflow hose attaches to a manifold made from PVC pieces with lots of cuts for water to push up through the pea gravel that goes on top.

Filling the filter and the main trough to check water flow and make sure the gravel isn’t too heavy for the supporting blocks.
File Apr 11, 9 52 28 AM
A few strategic cuts in the edge of the filter pan helps direct the spillway. We also drilled some holes under the edge to fine tune the water level. The plant is from our original tub pond and will give the fish some temporary food and cover.

Some cute miniature cattails and grocery-store watercress should help get the filter working. We’ll add more pea gravel and a newer watercress plant soon.

While we watch for leaks, levels and back-ups, Stewart is all about the tennis ball.

We moved the fish to their new home last night and they were still alive this morning! Not bad for pet store feeder fish. As we add appropriate water plants and the bog filter plants start working, the pond should provide a nice home for the fish, fertilizer (pond water)for the garden, refreshment for hummingbirds and other critters, and a pleasant spot in our hard-working garden for us.

Eventually there will be a sunken tub for plants like like their feet wet, and critters (like our tree frogs and Western toads) that prefer calmer water with no hungry goldfish. The over flow for that bog will create a third habitat for plants that prefer intermittent soaking. Once we get the water plants situated we’ll start hardscaping around the trough, making cool nooks in stacked mossy stones for resident amphibians to enjoy, plus adding some taller plants to help shade the water surface during summer.

Now we need to figure out how to get our new baby toad to make the move 🙂

P.s. Here is the high-tech artist’s rendition of the concept-pond. pond

Local warming is not a hoax

bleedingheartWinter is slowly being flushed out of Cascadia by our customary barrage of spring storms. Even though the days are longer, it’s hard to spend much time on outside chores in the mud and wind. Naturally the assorted plant life, wanted and unwanted, are taking advantage of the situation.

trillium

Local lore has always placed the bloom time of trilliums closer to Mother’s Day (with morel season coming after the first warm rain following Mother’s Day and the trilliums’ flowering). The past few years have not followed that pattern though, and we are always observing and adjusting our growing style to keep up.

Even though we got a few hard freezes this winter, we were finally able to winter over robust rosemary plants. Being against the south-facing wall of the garage, and out of the frigid winter winds from the north, made the difference. rosemary

The cold snaps also didn’t hurt the greens we wintered over. A little Sluggo, some floating row cover during the coldest nights, and we managed a few salads. Now the kale is bolting and the red leaf lettuce has taken on a lovely color. Time to get more starts going, but the garden won’t be dry enough to till for a while yet. Perfect timing for the hen house compost to start settling into the cover crop before being turned under. wintergarden

The bay laurel trees we bought by mail back in 2011 arrived in tiny 4″ pots. Four years later, they are picking up speed and providing us with fresh herbage all year long. They are native to coastal rain forests a bit south of us, but seem to have adapted to our microclimate just fine. baylaurel

Our mad-scientist chicken experiments are starting to pay off. This year we barely had a dip in egg production, and made sure to hatch a LOT of eggs from those hard-working gals to keep winter laying genes in our bloodlines. Spring fever is starting to spread though, and our little Japanese banty, Marble, has gone broody. Teeny tiny dragon lady, sitting on someone else’s eggs 😀 broodybantyOur ’emergency’ tub pond we made mid-drought last summer ended up housing five pet store feeder fish and a few more plants.NewPond  Amazingly, the fish survived all winter, as did most of the plants (though not the water lily, whose corpse is in the basket beside the pond). In the lower left of the current picture is a thriving grocery-store watercress plant. tubpond The roots are contained in the plastic wrapper it came in, hopefully keeping it alive until we can move everything to the new pond. After much consideration (i.e. pondering pinboards) we abandoned our original concept of a large, naturalistic water feature for a more practical, productive above-ground stock tank pond. We’ll set it near the garden, and add an elevated bog filter, pumping water up through pea gravel planted with pretty plants as well as edible ones. This keeps the water healthy for fish and other critters and we get to use nutrient-rich pond water on the garden. In the meantime, our ‘pond’ is getting some practice holding rainwater. So far, so good!newpond The Pond Digger has an excellent video series on building a patio pond with bog filter. Check it out –  and stay tuned for updates.
