The storage life of onions is determined by the variety and storage conditions. When properly stored, good keepers such as 'Copra' and 'Stuttgarter' can be successfully stored for several months. Poor keepers, such as 'Walla Walla' and 'Sweet Spanish,' can only be stored for a few weeks.
High tunnels for growing vegetables and fruits are a production technology beginning to dot rural landscapes. More Iowa fruit and vegetable growers are adding high tunnels — also known as hoop houses — to their operations as information about the technology and available USDA funding is shared.

Dark green leafy vegetables are rich in the antioxidant lutein, which has been claimed to help reduce the risk of age-related macular degeneration (AMD), said Sarah Francis, an Iowa State University assistant professor and ISU Extension nutrition specialist. AMD is the leading cause of vision loss in adults age 65 and older, and nearly 10 million Americans have this eye disease. Since March is Age-related Macular Degeneration Awareness Month, lutein is gaining attention.
Snow and ice are headaches for motorists and pedestrians. To prevent accidents on slippery surfaces, highway departments, businesses and homeowners use deicing compounds to melt ice and snow on roadways, parking lots, sidewalks and driveways. While deicing materials improve travel conditions, they can damage automobiles, concrete surfaces and landscape plants.
All evergreens, and particularly broad leaf evergreens such as boxwood and rhododendron, are susceptible to winter desiccation. Winter desiccation also is referred to as winter burn or winter browning. Desiccation occurs when the evergreen's foliage loses moisture due to the bright winter sun and harsh winter winds. In winter the plants are not able to absorb enough additional moisture from the soil to replace the water that evaporates from the foliage and stems. In addition to making sure the plants are well watered before the onset of winter there are a few other measures homeowners can take to protect the plants.
Yellowjackets are the fairly small yellow and black wasps you often see in the fall looking for food near garbage cans and nervous picnickers. Yellowjacket wasps are primarily meat eaters, but they have a sweet tooth, especially in the fall.
Garlic (Allium sativum) is relatively easy to grow in the home garden. It is a member of the onion family along with leeks, chives and shallots. Each garlic bulb contains a dozen or more smaller bulbs, called cloves. The cloves are enclosed by a white or purplish, dry, parchment-like skin.
Iowa agriculture puts healthy, affordable food choices on the table of today’s consumers and it boosts county and state economies, according to a recently-completed economic analysis sponsored by the Coalition to Support Iowa’s Farmers (CSIF). As harvest takes place it is appropriate to note agriculture’s impact not only on the landscape, but on the state’s economy.
Plants that are well maintained during the year (proper pruning, watering and fertilizing) and that are healthy will be better candidates for winter survival. Winter conditions can kill plants in many ways, even some cold hardy plants. Their tops or roots may freeze. Some evergreens that do not have enough water supply in the soil may dry out when subjected to persistent winds.
