One of the gardens that we help maintain is on the Bay Friendly Garden Tour tomorrow. I really like the tour and the whole concept of Bay Friendly. It’s such a clear way to focus on the ecological implications of gardening, and the tour has the feel of real gardens made by actual gardeners. The bulk of this one was installed by a designer (Roger Raiche, who’s known around the Bay Area from working at the UC Botanical Garden and for introducing a lot of well-known native plant varieties, Vitis californica ‘Roger’s Red,’ California Wild Grape, being the first one that comes to mind but there are many many more) and it’s had us helping with the maintenance for several years, but it’s very much the owner’s garden. Over the years, she has moved and added and subtracted a lot of the plants, and she’s the one who keeps it in a showcase state. It’s a great place to walk through and appreciate plants.
This section of the garden was designed by the owner along with a Buddhist monk who helped in the garden for a little while before us. Virtually every plant is a transplant from some other part of the garden, almost no new plants were bought for the space. Quite a few classic garden plants — roses, rhododendrons, azaleas, a peony — ended up in this area, I think after struggling or being overcrowded somewhere else. The fence was built with bamboo that the monk harvested from our yard. Every garden should have a Buddhist monk work in it for a time.
I’ve posted photos from this garden a couple of times before, here and here. There is a post about the garden on the Bay Friendly blog and the garden got several paragraphs in a write-up of the tour at SF Gate. And Floradora has a number of nice photos from this garden and several others on the tour.
Some more photos are below. (more…)
I went to the UC Botanical Garden yesterday. Anita and I decided to get memberships for the year. We realized that the garden is actually quite close to our house, not quite as close and convenient as the Tilden garden, but almost, and we should get to know it better. This was the first visit of the year. The garden was in transition between winter and spring, the earliest plants in leaf but most of the other deciduous plants still dormant.
The South Africa section has a new section of moss rock wall. Really nice stonework, dramatic contrast between the boulders and the walls. Be interesting to see what they plant, something with an intense flower no doubt, based on everything else in that section. I think it’s my favorite section of the garden.
It’s hard to think of a flower like this as the natural bloom and not a cultivar that has been bred by humans, but the UC has only wild collected seed.
I don’t remember noticing this vertical stone before. I think that’s a flowering quince behind it.
The ceanothus were going in the native section, but a lot of the other spring bloomers were just getting ready to break. Like the Tilden garden, the UC is a little later than my more coastal garden.
The Summer Holly, Comarystophylis diversifolia, was covered in buds. I’m not sure I’ve ever seen one in full bloom. The Oso Berry, Oemleria cerasiformis, is another one that I don’t often see in bloom.
And there is patch of Giant Coreopsis, the star of my recent bloom day, looking like they wandered over from the South Africa section. Such a strange plant; it’s very clear to me why I need one in my own garden and why I’ve never planted one for anyone else.
I was recently back at a garden where I did a day of rock work last summer, a short section of moss rock wall along a sloping path. When I built the wall, the client and I incorporated a couple of cracked pots into the wall where it tapers into the slope, and then she transplanted a number of her succulents to plant along the wall and in the pots. It’s one of our only gardens in which the client is also a gardener, and it was nice to now see how her planting has begun to fill in. The plants in the cracked pots still need a little more time to spread, but I think they already look pretty cool.
The wall in the background was already there, built by the company who installed the garden five years ago. I like the choice of aloes to plant along the top of it; they do well there, and their pokiness discourages people from messing with the rocks.
The garden is quite spectacular and worthy of a longer post some day. There are always things blooming and I usually take a few photos while I’m there; the shots of the swallowtail and prostanthera in my last post are from this garden. When the prostanthera is done, this member of the aster family will be in full bloom. I’m not sure what it is, but I like the look of the flower buds, and when it gets going, it puts on quite a show. Does anyone know it? I would try to figure it out, but the aster family is mighty big.
Before and after photos of a dry stack wall we recently repaired. The original wall was built about fifty years ago with just a single rock type, and then at some point the red and grey river stones were added, probably during a repair job but also possibly because someone wanted to borrow stones for another one of the walls on the property.
The big issue obviously was the two cedar trees, which had pushed the wall apart and partially swallowed many of the original foundation stones. A few of the stones were literally engulfed by the root/trunk of the trees; we had to leave those embedded stones in place and just stack in front of them. We moved the wall forward six inches, added a gravel foundation and gravel backfill, and scavenged the yard for enough of the original moss rock to restack the wall with a single rock type, discarding the river stones. By the end of the day, we had just a single leftover rock about the size of a softball; every single other moss rock that we could find on the property had been used in the wall. Eventually the trees will push the wall apart again, but then it can be stacked one more time.
Last December we were hired to do a similar repair on another fifty-year-old wall that had been pushed over by a redwood tree. The difference with that wall, though, was that it had been built (poorly) with mortar. To repair that wall, we had to demolish it with hammers and we were unable to salvage almost any of the stone; it was fit only to be re-used as rubble backfill and we had to buy a pallet and a half of new stone. So the repair job became a replacement job. And, of course, it also became much more time-consuming and expensive, taking three times as long and costing four or five times as much money. It’s a big factor to consider in debates about mortar versus dry stack: mortared walls stand up well for a long time, but when they do eventually need repair work, it becomes a much bigger job to repair them and they frequently need to be completely replaced. Dry stack walls do typically need to be repaired more often, but those repairs are also typically much easier and much cheaper over the life of the wall.
