$195,140 worth of birches?

We once had to do a lot of talking to convince a client that he didn’t want to chop down a healthy live oak that was just beginning to develop the kind of dramatic architecture that can’t be purchased with anything other than time. Since then, I’ve been wanting a dollar value for what a tree can add to a property, a number that’s easily cited and perhaps easily dismissed, but undeniably monetary and specific. A number like $8,870, the number that a recent study came up with after looking at how the presence or absence of street trees affected the sale prices for homes sold in east Portland during 2006-7. (The houses with trees also sold an average of 1.7 days quicker.) It’s obviously one of those statistics which can’t be applied too literally, but the researchers seem to have made an effort to account for some of the other variables that might surround the real estate sales. And though it is somewhat mercenary and doesn’t account for the many environmental and aesthetic benefits of trees and there probably isn’t a direct causal relationship, it might help people appreciate their trees more. What homeowner could hear that stat and not go right out to get a street tree? Personally, I’m sure I’ll cite the number at some point in the future, possibly to our landlord who knows that Anita and I are responsible for adding six street trees to our block. Shouldn’t that get us $53,220 credit towards our rent?

In a somewhat related note, I’ve always liked this planting of birches in my neighborhood and this post seems like the most reasonable time to mention it. The planting has an impressive total of 22 birches, which is 19 more than anyone else ever has. I’m pretty sure the birches count as ‘good overall tree cover,’ rather than as individual $8,870 trees, but there’s no question they make the house more valuable and desirable. The trees do the sun-in-winter, shade-in-summer thing for the house, and the planting always looks remarkably good, even when the understory needs maintenance. Designers talk about being bold or committed; 22 birches shows a serious level of commitment. Props to whoever planted them.

Bottle Tree in November

I’m intrigued by the Southern and African tradition of making bottle trees to trap evil spirits, but living in California I don’t know much about it and I hadn’t ever seen one in person, so I was pleased to discover one in my neighborhood. It’s in front of a house with various symbols painted on the front door and the utility box, and while I was taking the pbotos a guy whizzed past me on a bicycle and said, “Careful! They’re witches!”

Felder Rushing has a great collection of photos and a short history of the practice. And there’s a massive flickr collection. Traditionally, it seems to have been done with a dead tree or with sticks stuck in the ground; Crape Myrtles are the iconic species. Nowadays many are constructed of metal or some other material, rather than an actual tree. Very few seem to be from a tree that is still alive.

The Utility Box

I don’t want to mess with any witch juju, but it seems okay to show the utility box which has the same stars and moons as the front door. It never would have occurred to me to adorn a utility box. It’s surprisingly pleasing.

A while back, James at LostintheLandscape did a post titled Our Gardens After We’re Gone, musing about what might happen to his garden if or when he is no longer stewarding it. TownMouse and Bradzio at RootedinCalifornia and probably some other folks followed up with posts about what might happen to their own gardens. It makes sense that it was such a popular topic; gardening is largely about planning and envisioning the future. Anita and I have to do that pretty much all the time, and quite a few of the gardens we install are essentially a ‘garden with us gone’. After we design and plant, we usually return to do maintenance occasionally, but often times we just walk away. There are a few gardens out there that we installed and never saw again. It’s interesting to imagine what they look like.

One garden that we do see on a weekly basis is an example of some of the different things that can happen. We installed it four years ago and maintained it for about two, but then the client moved and took some of the plants with him. It was a shock the first time I saw the garden without them, but now I’m used to it and I find it interesting to see how the rest of the planting has endured.

The Intact Section (minus a couple of shrubs in the back right)

This section is still largely intact, with just a couple of shrubs missing. It looks like the new tenants might be weeding it and watering (the irrigation system was a casualty when the plants were transplanted, but someone might be hand-watering), though it’s hard to guess about the watering this early in the dry season. The weeds were pretty thoroughly eradicated by the time we stopped maintaining it, so the plants might be holding off interlopers.

Coyote Brush Pioneer

This section, with every plant moved to the new location, is a landscape designer’s memento mori. Coyote brush, one of the main pioneer plants in this area has already moved in. Without humans pulling the volunteers, I think coyote brush would pop up in almost every garden we’ve ever installed.

Ceanothus with weeds

This Ceanothus and the Salvia clevelandii in the first photo are fighting the good fight against weeds. This section was never on irrigation and clearly doesn’t get any weeding. Salvia and ceanothus versus weeds, who will win? There’s probably some coyote brush in there somewhere getting ready to join the battle.

The Smokebush at its New Home

This smokebush is one of the plants that was transplanted to the new location. It’s easy to understand why the owner would want to take it with him.

This June Bloom Day finds the garden needing some clean up and maintenance, but with plenty of things blooming. I like how the Brodiaeas look and the big spicebush in the back is really happy and the purple leaved canna in our gray water container is about to start blooming, but all of the spring bloomers still need to be deadheaded and there are bamboo leaves in all the plants, and the skunks have also started digging in the garden. I can hear them out there digging as I do this post. There are four young ones in the local family this year, an improvement over last year when there were seven.

Oriental Lily

This Oriental lily is probably the most accurate depiction of the state of the garden.

Lemon Lily, Lilium parryi

I have several Lilium parryi, the native Lemon Lily, grown from seed, now in gallon pots. This is their third year and my second flower. The flower doesn’t last long, but it’s really pretty.

Fried Egg Flower, Matillija Poppy

This year the Matillija poppies really remind me of fried eggs.

Monardella macrantha Marian Sampson

The Monardella macrantha is draping down into the foliage of some Clarkia. It might have my favorite red of all the California natives.

Scrophularia

The Scrophularia is a nice red if you put your face or camera about three inches away. Otherwise, it can be hard to tell that it’s blooming. I like the Galvezia from a little more of a distance.

Galvezia speciosa, Island Snapdragon

Calycanthus occidentalis, Western Spicebush

A couple more shots of the Spicebush which has completely taken over the area in front of the outdoor shower. The fragrance of the flowers is just barely noticeable, unlike the wisteria which was very strong. Interestingly, the fallen petals of the wisteria burned holes through the leaves everywhere that they landed on the spicebush. None of the other plants have that problem.

Nasturtium in the Spicebush

I’ve been keeping a list of everything in bloom in our garden each month, so I’ll be adding that to this post when I get a chance. It usually takes me a couple of days to add it.

‘…a hole in back you could put your fist in, if it were a small fist and you wanted to put it there…’ Hemingway, A Natural History of the Dead

The last few weeks we’ve been working in a yard that has a wild bee hive in an old silver maple. Apparently, they vanish each winter and a big, noisy swarm returns in the spring. On cold days, the hole in the trunk steams faintly. The bees are mellow in the morning, but in the late afternoon they make a loud buzz like every cartoon representation of an angry bee swarm that I’ve ever seen. It’s a little disconcerting, though they are far too busy to pay any attention to me.

I bet there’s some nice honey in there, but I’m sure not going in after it.

For a while now I’ve been meaning to post about converting lawns to low-water plants. We do it 2 or 3 times a year, and Anita and I have both taught workshops on the process. We convert the lawns with the use of sheet-mulch: a smothering layer of newspaper or cardboard covered by compost and mulch. It’s really easy and it works well, one of the few cases in life where the easiest way to do something is also the most effective.

Yesterday after the rain eased I did an irrigation checkup at a lawn we converted to plants two years ago. It was looking pretty good. There’s some bermuda grass in one area and some other weeds in a few places, but the lawn is long gone. Here are some photos of that project:

We first had the client stop watering the lawn for a month. EBMUD has a rebate program that gives $.50 for every square foot of lawn taken out and replaced with low-water plants and drip irrigation. If you’re going get a rebate, make sure you get them out for the pre-inspection before you stop watering; they only give rebates for removal of green lawns.

We covered the lawn with newspaper (cardboard also works) and a layer of compost or planting mix. We also cut away the sod at the edges next to the sidewalk and put those pieces of sod in a couple of piles covered with compost. Lawns tend to be flat and geometric, so we like to form a low mound or two for visual interest. The mound does not have be high — even 4 or 6 inches is enough — and it really helps banish the ghost of the flat lawn underneath.

We put out the plants and planted them through the soil and newspaper. The neighbors always think we’re crazy when we start covering everything with newspaper, but the arrival of the plants starts to restore their confidence.

Another way to do it is to put a layer of compost on the lawn, plant, put out the layer of newspaper, and then cover it with mulch. The newspaper is more likely to show if it’s on top of the compost, but you don’t have to deal with the newspaper while you are planting. We usually do the newspaper about 12 sheets thick and we try to make sure it overlaps by several inches. We soak the newspaper in a bucket of water before we lay it down so that it sticks together, like paper-mache for your yard. Compost or mulch needs to go on top of it as soon as possible to hold it down and keep it from blowing away. Thicker layers are better, but a lot of time we’re working close to a sidewalk where it’s not practical to make a thick layer.

These two photos are from soon after planting.

The next photo is from last year, when the planting was a year old.

Between the compost, the decaying lawn, and the remnant fertilizers from the lawn, the plants usually grow really quickly. The Luma apiculata (Chilean Myrtle) planted as a 1 gallon is already more than 8 feet tall after only 2 years.

StopWaste has a great step by step breakdown of the process and page with tips. Sheet-mulching is a little like cooking, everyone does it with their own slight variation, but StopWaste has a solid recipe.
