While some spring flowering trees and shrubs performed admirably this season, some species had few or no blooms at all. In addition, some plants were so late to leaf out they had many of us concerned that they had died overwinter. Some shrubs such as forsythia flowered only on the lower branches, where snow cover provided good insulation. While it is still possible that these plants may continue to show effects of the harsh winter, […]
Rhubarb, also known as pieplant, is an herbaceous perennial grown for its unique, tart flavor of the thick leaf stalks (petioles). Rhubarb sends up its thick, edible stalks early in the spring, a much-anticipated harbinger of the coming growing season. Harvest can begin as soon as the stalks are large enough to cut and continues on through late spring. You can cut the stalks with a sharp knife, but be careful not to injure any […]
Growing your own garden transplants from seed may take some extra work, but it does have its advantages. You’ll have a much wider choice of species and cultivars since most garden centers have limited space and tend to carry primarily the plants that sell quickly. Rather than having to buy a dozen of one type of tomato when you only need one or two, you can grow just the amount of each plant you […]
Winter’s howling winds and frigid temperatures are challenging for all woody landscape plants. Although our plants are fully dormant at this time, the plant tissue is still subject to losing too much water – a condition called desiccation. This year’s unusually heavy and consistent snow cover provides good insulation, and most plants went into winter with a good moisture supply this year. However, when the ground is frozen solid and freezing temperatures are accompanied by […]
When winter temperatures dip below zero and winds howl across the prairie, gardeners may worry that their trees and shrubs are taking a beating. No need for doom and gloom yet – most hardy landscape and orchard plants are reasonably able to cope with most of our winters, including our recent polar vortex. Many factors influence plant injury, including plant species and cultivars, degree of plant dormancy and overall plant health. How low the temperature […]
Switchgrass Northwind has swept its way to the top as the Perennial Plant Association’s Perennial Plant of the Year for 2014. The Northwind cultivar of Panicum virgatum is distinguished by starkly upright habit compared to the original species. Northwind provides landscape interest from late summer through winter. Blooms appear in late summer, followed by upright seed heads and golden fall foliage. In winter, enjoy the musical swishing sounds as the sturdy foliage sways in the […]
Homeowners assessing tree damage caused by recent storms will want to make a few important decisions soon. Small trees with minor damage can probably be taken care of by the homeowner, but large, mature trees likely will need the help of a professional tree service. It can be hard to decide whether trees with severe damage should be removed. Homeowners often are reluctant to cut down a tree, either because of sentimental attachment or because […]
Perhaps the most challenging landscaping problem is that of what to plant on a steep slope. Slopes require plants that can establish quickly, tolerant of fluctuating soil moisture and potentially poor nutrient availability, and require little care once established. You’re likely looking for small plants for filling this rather tall order! Turf grass is one of the most popular ground covers for keeping soil in place, but mowing on an incline is inconvenient at best […]
Nothing beats fresh-picked vegetables picked from the garden, but timing is everything! Harvesting at the right stage is essential – proper storage will help maintain homegrown freshness. Some crops are best harvested frequently while still immature, while others need to mature as long as possible. Crops also vary in their optimal storage requirements; some do best in cold, moist storage; others do best in dry storage. The following crops are grouped by similarity of storage […]
Despite the endless list of potential problems, tomatoes continue to be the most popular plant in Midwest vegetable gardens. Many tomato problems are related to environmental factors such as temperature and moisture, rather than insects or disease. The most common tomato affliction is blossom-end rot, so named for the black, leathery scar that occurs on the blossom end, instead of the stem end, of the fruit. Blossom-end rot most frequently occurs when there are extremes […]
