The Power of Walls

Walls can do amazing things for a garden. Here in Eugene we rarely see free-standing walls enclosing spaces, but retaining walls abound. I’ve visited many hillside gardens in Eugene that would be just about impossible to cultivate or enjoy without the transformative power of terracing and retaining walls. Materials vary. Poured concrete is practical and can also look great in certain settings. Railroad ties and treated lumber are relatively cheap. Concrete blocks of various kinds are popular, but to me they always look like an opportunity missed. Continue reading

Tips on what bulbs to plant and when

It’s time to plant garlic and shallots — and other kinds of bulbs, as well. It’s inspiring, tucking those little bulbs in the ground with thoughts of future good eating and so is tucking bulbs in the ground amidst visions of spring flowers. I’ve enjoyed the ritual of fall bulb planting as long as I can remember and look forward to it every year. If you are not in the habit, though, the window for buying and planting spring-flowering bulbs is easy to miss. Continue reading 

Planting by the Numbers

Not all blueberries are created equal

Mmm-mmm, blueberries. Who doesn’t love them? When we can keep the birds from eating the fruit, this is surely one of the most rewarding edibles in the garden. They don’t take up a huge amount of space, and they are easy to grow in our area, given sun, acid soil and plenty of water. And the plants are beautiful, more or less year-round. To top it off, raw blueberries are among the most nutrient-rich plant foods available — low in calories and loaded with plant nutrients such as soluble fiber, minerals, vitamins and antioxidants.

Annual vines provide color in late summer

This time of year, an abundance of annual vines suddenly appears in garden stores. Annual vines are inexpensive to grow and fun to play with, and have the added virtue that they are at their best in August and September, when flower gardens can be in need of a lift. Plant them in the ground or in containers, and try something different every year. Vines are wonderful for softening blank house walls, concealing unsightly fences and adding instant height in young or temporary gardens. Continue reading 

A Win for the Bees?

Europe takes action while U.S. bees take a hit

On April 28, the European Commission (the governing body of the European Union) voted to impose a two-year moratorium on the use of neonicotinoid insecticides on food crops attractive to bees and other pollinators. Neonicotinoids, now the most widely used pesticide class in the world, are suspected of contributing to colony collapse disorder (CCD) in honey bees, and their use is already restricted in France, Germany, Italy and Slovenia.

Why New Trees Fail

Tangled roots and other fatal hazards

It’s annoying when a newly planted shrub or perennial dies on you, but unless it was a gift or it’s rare and hard to replace, it isn’t all that serious. Trees are another matter. Young trees can be expensive, and it takes quite a bit of effort to plant one. Most importantly, if the failing tree takes several years to die, there’s precious time lost in achieving the purpose for which you planted it, whether for fruit, shade, a focal point, screening or just a nice, imposing plant companion.  Continue reading 

Take Your Temperature

Planting vegetables before May

Until this year, a month-by-month portion of Eugene Weekly’s annual vegetable planting guide began in May. In a way, that’s logical — May is about when our heavier valley soils become workable. These days, however, with many people building raised beds and all-season gardening becoming ever more popular, lots of gardeners know that the planting year can start a lot earlier.  Continue reading 

Are We Getting Warmer?

Planting for a disrupted climate

The numbers are in, says The New York Times: 2012 was the hottest year ever recorded in the contiguous U.S. 2012 also turned out to be the second-worst on record for climate extremes, amassing 11 weather disasters that exceeded $1 billion in costs, including tornadoes, freak storms, floods and catastrophic drought. Globally, the decade from 2000 to 2010 was the warmest on record. Nobody who is under 28 has lived through a month of global temperatures that fell below the 20th century average, because the last such month was February 1985. Welcome to a warmer world.  Continue reading
