Our Forests



The great French Marshall Lyautey once asked his gardener to plant a tree. The gardener objected that the tree was slow growing and would not reach maturity for 100 years. The Marshall replied, 'In that case, there is no time to lose; plant it this afternoon!'
John F. Kennedy (1917 - 1963)

Micro Climate

How to Grow What Shouldn't grow here

Some years ago we notices this lavender wild flower growing in corner of the L of our house. Laura posted pics and a friend identified as early Meadow Rue. I looked up the range map of this plant, and it's mostly an eastern plant, with only a few reported sitings out west. Two years later we had another on the east side of the greenhouse.

With some attention, you can use microclimates to your benefit. Some subtle difference that may enable a plant to do much better than it would otherwise.

Here are some examples of microclimate planning:

Cold air drainage On a clear night the top of the soil radiates heat into space. Several inches of air next to the dirt cool off, then slide off down the hill, collecting in the valleys. Some plants, notably the stone fruits (plums, apricots, cherries...) tend to bloom early. (Vancouver has a cherry blossom festival in February!) By putting them on a hill 5-10 vertical feet above the bottom can make the difference between loosing your crop from a late frost.

On an early morning, just at sunrise, when it's calm and clear, walk around your yard. You may be able to feel the difference. Notice where the fog pockets are. Notice where the dew is heavier.

Early Spring We have a row of spruce trees near the house. Those trees hold with spring warmth, and the snow is gone 3 weeks before the rest of the yard. Next year I'm putting in a hundred crocuses. See if I can have the first crocus in the neighborhood.

Watch the where the snow melts first. This will be the first workable soil in spring, and will be warm sooner than the rest of the garden.

This picture is just a place holder for something later.

Postponing Spring Back to those stone fruit. Apricots are borderline here. Many years they bloom, but a late frost takes them out. You need to trick them into holding back. Try this: On the 15th of May, near noon, go to the north side of a building in your yard, and mark the shadow line. You can also use the north side of a shelterbelt. Plant your apricot 6 feet in from the edge of the line. This spot is almost certainly a place where snow collects in winter, and is late moving off in summer. This will keep the roots cold enough to postpone bud break by a week. The top of the tree will be in the sun in late August so the fruit has a chance to get ripe.

Collecting Snow I have 8 acres that I use for growing trees. I have 30 foot high poplar trees every 200 feet. The rest of my fields are bare right now (Early March, dry winter) but the shelterbelt protected area still has 8 inches of snow. In winter this extra snow means that the hoof rats (deer) have to work harder to get through deeper snow. Mostly they don't. They go somewhere else where they don't have to work as hard.
