It is not unusual for annual flowers, such as impatiens and petunias, to look a bit peaked about the middle of summer. For some plants, such as pansies, stock and snapdragons, stress from summer heat turns off the initiation of flowers. But most flowering annuals are fairly heat tolerant and can be revived with a little pinch of their stems and a sip of nutrients. Though for the most part, our temperatures haven’t been all […]
Recent torrential rains have brought about flooded conditions in many gardens and landscapes. As floodwaters 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. If you have produce ready to harvest, the issue of food safety is best handled with caution. Clearly, if floodwater is contaminated with raw sewage, it is […]

As the dazzling display of spring-flowering bulbs comes to a close, it’s time for a bit of spring cleaning. Now is the time to remove spent blossoms and prevent seed production from stealing needed carbohydrate reserves that can be better saved for next year’s bloom. Even though the foliage that remains is not very attractive and, in some cases, is downright unsightly, resist the urge to cut those green leaves off the plants. The health […]
Although most gardeners aim to bring in a good fruit crop on their plants, there are a few situations where a barren plant is preferred. Some homeowners would love to find a way to keep certain landscape plants from dropping their fruits onto driveways and sidewalks. There are a few methods that can help reduce the amount of fruit production on both ornamental and fruit trees. Hand removal of faded blooms, or young fruits, works […]
While it is too early to plant tomatoes, now is the perfect time to plant lettuce. The key to growing a successful crop is to plant and mature the lettuce in cool weather. Lettuce is an annual plant that will bolt (produce a flower stalk) and become bitter when temperatures stay above 70 F. Iceberg, or more correctly called crisp head type lettuce, used to predominate produce shelves at most grocery stores. Crisp head cultivars […]
Although recent weather may have delayed some of your planting plans, it’s time to spring into action in the garden. Most gardeners will find there are still some chores to finish up from fall and winter. If you applied winter protective mulch to plants such as strawberries and newly planted perennials, be sure to pull that mulch back away from the plants as they emerge. But keep that mulch close by, just in case spring […]
For many gardeners, pruning seems to be the most daunting chore in the home orchard. In an effort to avoid cutting off too much, many of us end up not cutting at all and end up with overgrown trees. Too little pruning can result in overcrowded, unhealthy branches that produce small fruit and/or few of them. On the other hand, severe pruning also can remove much of the crop potential. Not all fruit species grow […]
The fresh crop of garden catalogs brings me hope for the coming spring gardening season. Once again, plant breeders are tempting us with new, better and unique looks to our old, familiar crops. Carrot ‘Romeo’ blends a petite ball shape with smooth skin that needs no peeling. Harvest for peak flavor when they reach about an inch or so in diameter, about 60 days from seed. (Renee’s Garden Seeds) Cucumber ‘Yellow Submarine’ bears large, 8-inch-long […]
No matter what you call it, there’s no question that the tree known botanically as Maclura pomifera is a unique curiosity. Depending on where you’re from, this tree has such names as hedge-apple, osage orange, bodark, bowwood and bois d’arc! Originally, this plant hailed from the southwestern United States, but was so widely planted throughout the Midwest as a hedgerow, that it is now considered to be “naturalized” throughout much of the eastern United States […]
