Just as sure as you try to predict the weather, it is likely to change. But going out on a limb, I predict that we will have an early fall regarding color display this year. Not a very risky prediction, considering that many plants already are starting to display their fall colors! And to go even farther out on that limb, I’ll predict that the colors won’t be as brilliant as perhaps they were in […]
Much to the dismay of homeowners, landscape trees sometimes grow roots on top of the surface of the lawn or possibly even buckle sidewalks and driveways. These surface roots can be quite a nuisance to lawn mowers and running feet. There are several reasons why the roots come to the surface. Some tree species seem to be more prone to surface roots than others, most notably silver maple, poplar and willow. But almost any large, […]
Late summer or early autumn is the best time to divide perennials that bloom in spring and summer. But not all perennials need to be divided. Generally, perennials should be divided to rejuvenate an old, overgrown planting or to increase the number of plants in the garden. Plants such as peonies, iris, hosta and daylilies are among the most common garden perennials that are easily divided. Making divisions is a simple task, but should be […]
Sultry summer weather is not only tough on gardeners but on our plants as well. In addition to garden and landscape plants gasping for water, some vegetable crops have trouble producing when under stress. Tomatoes, peppers, melons, squash, pumpkins, cucumbers and beans often drop their blossoms without setting fruit when day temperatures are above 90 F. There’s not much you can do but wait for cooler temperatures to prevail. As more favorable conditions return, […]
Try to have a discussion about hydrangea among your gardening friends, and you’re likely to start a rather lively debate. What type to grow, when to prune, why doesn’t it flower and how can I change the flower color from pink to blue are among the most frequently asked hydrangea questions. There are many different species of hydrangea, not to mention cultivars of those species. So, these questions are a bit difficult to answer, unless […]
It may seem a bit late to be planting Halloween jack-o’ lanterns, but there’s still time to plant if you get growing quickly. The key will be to choose a cultivar with a relatively low number of days to maturity when planted from seed. There are early-, mid- and late-season cultivars of pumpkin, ranging from about 85-120 days to maturity. You’ll want to look for those in the “early-season” (around 90 days) category. While it […]
Asparagus and rhubarb may be the earliest garden crops to be harvested, but may also be the first crops to stop harvesting as well. Because of their perennial nature, asparagus and rhubarb must be given a chance to rebuild food reserves so that a bumper crop can be produced again next year. A good rule of thumb is to stop harvesting asparagus about the middle of June, allowing the spears to produce large, fern-like […]
Recent torrential rains have brought about flooded conditions in many gardens and landscapes. As flood waters recede and folks get about the business of putting homes and lives back together, questions arise as to the safety of produce from flooded gardens, as well as potential damage to landscape plants. For those who have actually had a chance to put in early cool-season crops, the issue of food safety from the garden is best handled with […]
Sunflowers have long been included in the typical Midwestern garden, but modern hybrids have greatly expanded the palette of choices for today’s garden. Whether you want short, medium or tall; yellow, burgundy, bronze or brown; seed for the birds; or just pretty look at, there’s a sunflower for you. Gardeners will find two different types of sunflowers available from garden centers and mail-order catalogs: Those that are grown for their edible seeds, and those that […]
Gardening in raised beds can be just the answer for would-be gardeners who would love to grow their own vegetables and flowers but lack the space or physical ability for a traditional garden. However, recent controversy regarding chemical wood preservation treatments has left many gardeners wondering about the safety of treated lumber. The Environmental Protection Agency (EPA) recently announced that lumber treated with chromated copper arsenate (CCA) will be phased out for use in consumer/residential […]
