Question from Barbara:
Do white birch trees grow in CA?

Answer from Pat:
You are the second person today who has written to ask about European white birch (Betula pendula.) I agree it’s lovely looking tree. No doubt about that. Also, yes it will grow here in California, probably better in coastal northern California than Southern California. The problem is that this tree comes with a flock of built-in problems. It is prone to attack by borers, which can girdle the bark and kill the tree. It hates extreme heat, it does better with a cold winter, and also, it requires deep, well drained, fertile soil, and not many gardens here can fill this requirement. However, a few gardens provide the right situation for European birch which are as follows: Plentiful irrigation, fast drainage, deep fertile soil, afternoon shade from burning hot sun, and an organic garden with many beneficials in residence to protect against borers and leaf miners. When you count all these requirements, perhaps you might decide it would be better to study the lists in Sunset Western Garden Book and find some tree you like that is well- adapted to growing in a dry Mediterranean climate where you don’t need to stand on your head trying to recreate England or New England here in California.

However, I understand falling in love. If you fall in love with a man because he is so wonderful, but he has a few built-in faults, I would say it’s better to marry him anyway and find ways to cope. Sometimes you just can’t help yourself. So the other course of action is to knock yourself out doing everything right: Fix drainage so it’s rapid, make soil magnificent, build a raised bed or mound the soil to create perfection beyond belief, feed with organic fertilizer, introduce beneficial insects galore, provide afternoon shade, and protect the patient from burning heat— (hmm, an electric fan?… How far are we going to go?) But if you’re willing to do all this, then throw your heart over the jump and plant the tree you love. Before doing all this, however, please read elsewhere on this blog the caveats I have written to various other people afflicted with violent, irrational love for European white birch (Betula pendula.)

    • Good to know that beetles and other problems afflicting silver birch trees are doing someone a good turn.

  3. the american paper birch is also called white birch Betula papyrifera … is the tradition of 3 birch from Russia?

    • Birch is the national tree of Russia, where seemingly endless forests of these trees cover vast tracts of land. Because of this and because the trees are so beautiful, the birch tree is almost a sacred symbol for Russians. At certain times of year Russians drink the sap, which is believed to have healing qualities. Additionally, besides being ornamental, birch trees and birch wood have many practical uses. Then there is the symbolism of the tree, just as I think of the purple-heather covered moors as the hallmark of my Yorkshire birthplace, so the Russians harken back to the birch tree and remember with fondness the forests that graced their homeland. Perhaps the European white birch (Betula pendula) is the one most beloved Russian species because of its silvery white bark with characteristic black markings. Its special look is similar to our American species, the canoe birch or paper birch (Betula papyrifera), that Indians used for making canoes. Besides B. pendula, there are at least three other species of birch found growing in Russia: B. costata, B. platyphylla, and B. pubescens. All are revered, but not all have white bark. From my own experience I agree with the Russians there is something amazing, perhaps almost spiritual about birch trees, even those with apparently plain gray bark. The smooth gray bark of a birch tree, glimpsed in earliest spring against a patch of freshly sprouting green grass in a forest clearing can impact one’s life forever. The reason that one so often sees birch trees sold or grown in a clump of three is that they are often found in nature growing in a clump and three is a better number for nurseries to grow as a group than, for example, five of them together. I don’t think this habit of sale began in Russia, but I don’t know for sure. If you look at photographs of Russian forests of birch trees usually one will see that most of the trees grow singly but there almost always will be a clump here and there of several birch trees growing together in one close group. I think this became a habitual way to grow silver birch in America because birch trees are tall and narrow and naturally look better growing — if not in a great plantation, then at least in a clump with the trunks angled out from one another in a graceful grouping. There are also several practical reasons for planting these trees in a group: Artistically, three is a good number. Planting three together results in more shade for the roots. Three trees gives one more of the lovely bark to admire without taking up more space, and finally by planting three together they compete with one another, thus they stay smaller and create a more attractive accent in a garden than would one single tall tree.

    I am looking for a tree that was planted along the Ca. railroads to supply them with railroads ties. It did not work but now Ca. has many of these trees. I believe they may have come from Australia where there wood was very hard; not so here, or some reason. Do you know of any such tree? I thought it may be the Birch tree.

    • The tree that was used in Australia for railroad ties was eucalyptus. Several species of eucalyptus are useful for lumber in Australia and several of these make excellent railroad ties since the wood is extremely hard and long-lasting, with little tendency to rot. Beginning in 1850 about fifty species of eucalyptus were imported into the USA and later around 1910 eighteen varieties of eucalyptus were selected among those known in Australia as especially useful for timber, including certain ones for railroad ties. These species were planted in several areas up and down the West coast, including a huge plantation by the Santa Fe Railroad in the area of San Diego County now known as Rancho Santa Fe. The main species planted in Rancho Santa Fe seems to have been red gum eucalyptus (E. camaldulensis), one of the best two eucalyptus known in its native Australia for lumber and railroad ties, and white ironbark (Eucalyptus leucoxylon), which is also a tree prized as lumber in Australia, but some other species were tried out as well. Unfortunately, red ironbark is highly susceptible to the Red Gum Lerp Psyllid, that got started in California in 1998 and this has caused repeated defoliation of the red gum trees and often resulted in death of this species of eucalyptus in Rancho Santa Fe.

      Around 1920 a few trees were harvested and given a trial as railroad ties by the Santa Fe, but unfortunately the weather in California is not suited to growing eucalyptus for lumber. The wood was found to be internally twisted and having a tendency to split. All this happened long before any pests afflicted eucalyptus in California so you can imaging what a huge disappointment this was to the railroad. The railroad sold off their land for development and the first buyers came from Chicago, where the railroad’s headquarters were located. Rancho Santa Fe was touted to wealthy people there as a great place to retire due to its fabulous climate.

      Though eucalyptus was a failure here as a timber tree it could be used for other purposes and wherever groves of them were planted, many ended up as firewood. In Rancho Santa Fe when the trees failed to produce the hoped-for railroad ties, the area was subdivided and the trees became so prized for their appearance and drought-resistance that they turned into a hallmark of one of the wealthiest communities in the the United States. Meanwhile farmers had discovered that the blue gum eucalyptus (E. globulus) was useful as a windbreak and it was widely used agriculturally, especially in orange groves to stop the damaging effects of seasonal Santa Ana winds. A few eucalyptus are good in gardens, such as lemongum eucalyptus (E. citriodora) which unlike many others is deep-rooted, and many are ornamental, prize like flame eucalyptus (E. ficifola) for its stunning floral display, or like E. citriodora, for its handsome structure and all are known for ease of cultivation.
