Gardening Tips

Stressed firBy Mary Stewart
Many Oregonians have noticed widespread damage in landscape and forest trees this spring – and weather may be the culprit.
“Browning or dieback is often caused by weather-related stress, sometimes in combination with pests and diseases,” said Glenn Ahrens, a forester with Oregon State University’s Extension Service. Douglas-fir trees are the most common victims, he said, but stress due to weather is affecting many tree species and a variety of problems are showing up.
On some Douglas-firs, branches and tops are turning red or brown. Sometimes the entire tree dies. Older trees typically have milder symptoms.
“This sudden mortality or ‘flaring out’ of branches and tops is a classic symptom of drought in conifers,” Ahrens explained.

Charmingly warm weather coaxed roses into bloom early this year, which means dealing with the usual diseases and pests earlier, too.

Sweet potatoesBy Kym Pokorny
When he was nine years old and riding with his brother on the back of a two-seater tractor on 30 acres in southern California, Gary Jordan planted sweet potatoes one at a time.

Anyone who buys or inherits a fruit tree faces the intimidating crossroads of how, when and if they should prune.
“It’s one of the most difficult things for people to understand,” said Ross Penhallegon, horticulturist with Oregon State University’s Extension Service. “Ultimately, they make a few cuts and think, ‘Oh, I’m going to hurt the tree’ and run back into the house to watch TV.”

Stink bugBy Kym Pokorny

When leaves fall and days get shorter, stink bugs go on the move looking for a warm, dry place for winter. Often that means sharing our homes with these prehistoric-looking insects, whether we know it or not.
This year, it’s difficult not to know. Many homeowners have been inundated as the population of brown marmorated stink bugs (Halyomorpha halys) keeps increasing.

MistletoeJust how poisonous is holiday mistletoe?
By eNature
Almost all of us have come across American Mistletoe, the white or green-berried parasitic plant hung in doorways during the holiday season to elicit kisses from those standing beneath it.
Reputed to be the “kiss of death,” Mistletoe (the Phoradendron species is found in North America) is said by some to be so poisonous that humans can be killed if they ingest the leaves or berries.

ConiferBy Kym Pokorny
We buy live Christmas trees with the best of intentions, promising ourselves to plant them in the garden as soon as the holidays are over. But resolve has a way of fading like resolutions after January.
Moved outside without the care they need, the beautiful, and not inexpensive, trees meant to go in the ground in winter, languish, fade to brown and eventually die. One alternative is to buy plants meant to stay in pots, said Al Shay, a horticulture instructor at Oregon State University.
“It’s a trade-off,” he said. “You give up big trees for smaller, slower-growing plants that you can bring in year after year. But what’s small? Is four feet too small? Three feet? It’s relative.”

Cat with fireBy Kym Pokorny
Conscientious Oregonians have been storing up firewood for the inevitable cool days of winter and the experienced wood-gatherers know that dry, seasoned firewood burns most efficiently, provides the most heat and smokes the least.
In fact, unseasoned wood is not suitable for open fireplaces, according to Steve Bowers, a forester with Oregon State University Extension Service.
Ideally, wood should be purchased or gathered at least a year in advance of burning.

Plant gallsBy Peg Herring
Oregon State University plans to use a $3 million grant to study two groups of bacteria that result in millions of dollars in losses annually to the nation’s nursery industry.
Researchers will study Agrobacterium tumefaciens and Rhodococcus fascians, which deform hundreds of common landscape plants, including hostas, Shasta daisies, petunias and pansies.
