Espaliered fruit trees

Last week I wrote about the apricot tree I’m putting in to my garden this year, but I’m not going to stop my home-grown fruit attempts there. We’re building a fence this year (really- not like last year, when we just talked about building a fence), and I’ve managed to convince Brian that we should build a lattice fence, rather than the less complicated stockade-style fence. I’m pushing for the lattice fence not just because it will look good, but because it will let lots of light through for plants, including for espaliered apple trees.

Espaliered trees are trained so that the branches grow along a plane, rather than a sphere, cone, or vase. They can be trained along a fence, a wall, or wires that are connected to posts. In Seattle, you can see espaliered apple trees grown along wires in Magnuson Park, or out in Eastern Washington, there are plenty of orchards with espaliered trees. In fact, once you start looking for them, you’ll see them all over the place.

I’ll be growing espaliered trees mostly because they fit in small spaces that would be impractical for even a regular dwarf apple tree. I’m also excited for the challenge of pruning the trees, and because I think they’ll look really neat. My espaliered trees won’t get more than 5 feet tall, so they’ll be convenient for pruning, picking apples, and inspecting for diseases or pests. Many folks claim that espaliered trees are more productive. I haven’t found any good papers proving this, but I may just not know where to look.

Many people grow espaliered trees by starting with “whips”, which are one or two year old trees that look pretty much like a flexible stick with roots. Apple trees don’t start bearing fruit until they’re a few years old, so I will probably go the impatient route and buy some older trees from Raintree Nursery that have already been trained with three cordons (tiers of horizontal branches). It will be a little more expensive (about $60 per tree), but way less work and harder for me to screw up. We’re lucky to have a somewhat local nursery that sells espaliered trees for an affordable price- many states can’t say the same thing. Raintree Nursery even has several different varieties of espaliered trees for sale, including one which has six apple varieties grafted onto a single tree.

I also have photos of some great fences and formal kitchen gardens. If you’d like to interact a bit more with my Pinterest board, but aren’t on Pinterest yet, leave me a comment saying so, and I’ll send you an invite to Pinterest.

Home-grown Apricots in Seattle

I have dreams of wandering outside and plucking apricots off a tree in my own backyard. Yup, in Seattle.

There are plenty of fruit trees in Seattle- mostly apples, cherries, and plums, along with the occasional pear or fig tree. I haven’t seen an apricot tree in Seattle before, but I’m told it can be done, so I’m going plant one. Apricot trees like dry springs, which of couse Seattle doesn’t have, so there’s certainly a risk that the tree won’t produce fruit, or will outright die. 4-6′ trees only cost about $25, though, and young trees don’t really take up much space, so I figure it’s worth the price for the fun of the experiment.

I’m not going to plant just any apricot tree- like most plants, there are varieties that have been bred to survive and thrive in a range of conditions. The main attributes I’m looking at are the size of the tree and the ability to handle some soggy seasons. If I lived on the East side of the state, I’d also be looking at cold tolerance, and whether the trees are likely to bloom before the last frost (not a good thing). I’ve seen conflicting advice on which varieties produce best in the maritime Northwest, but in the end I’m trusting the folks at Raintree Nursery, because they have plenty of experience dealing with us west-siders.

Puget Gold Apricot

The variety I’ve chosen is called Puget Gold, which is the result of efforts by local breeders. It’s reported to set fruit fine despite our non-ideal springs, has a mature height around 15′, and is self-fertile. Being self-fertile means that it doesn’t need another apricot tree of a different variety nearby, to provide pollen, as many fruit trees do. Having a tree pollinate itself or another of the same variety (they’re produced asexually, which means that every tree of the same variety is genetically identical), leads to inbreeding, so some fruit trees have mechanisms to prevent self-fertilization. I’m not concerned about inbreeding, though, because the pits from my apricots aren’t going to be planted. Self-fertile trees sometimes still produce more fruit with another variety nearby, but I’ll see how my experiment goes before investing more time and space into apricot trees.

Most backyard fruit trees are grafted onto rootstocks. The “tree” part is called the scion, and the root part is the rootstock. One of the most obvious influences of the rootstock is the size of the tree, and how quickly it grows. Rootstocks can have a dwarfing effect, and are often categorized as standard, semi-dwarf, or dwarf. (Standard is the biggest). Rootstocks vary in their tolerance to cold and wet soils, and their resistance to soil pests such as nematodes. My apricot tree will be on a Lovell rootstock, which can also be used for other fruits such as peaches, plums, or almonds.

My first steps to maximize my chances of a healthy tree are to buy from a reputable nursery and properly pick a site and prepare it for planting. I’m counting on the nursery to provide me with a disease-free tree that’s been properly pruned for the last few years. Although I curse the slope of our property when I’m planning a fence or patio (or want to drive somewhere in a snow storm), it does provide excellent drainage, which is good for tree roots. I’m going to remove some arborvitae, to give the site more sun, and also because my arborvitae look uglier every year. If I didn’t already have orchard mason bees to provide pollination services, now would be a good time to order some, but I started raising them last spring, so I’m all set on that front.

Has anyone grown apricots (or peaches) in the maritime Northwest? I’d love to hear both success and failure stories.
