Dry summers are not that unusual in the Midwest, but this year’s dry spell – and now drought in many areas – has come considerably earlier than usual. Summer is just now officially getting started! Gardeners have a battle on their hands to keep plants healthy when extremely high temperatures are accompanied by lack of rain. During prolonged drought conditions, water restrictions or just limited ability to water to a huge number of plants, you […]
Many of our landscape plants are under stress this summer from one or more factors, including excessive heat and humidity, insect feeding, disease infection, and depending on location and timing, drought and/or excessive rains, wind and hail. Some trees are already losing leaves, and leaves may be turning color before they drop. Early defoliation is common when plants are under stress, and this season has been quite challenging for many trees, both old and young. […]
No matter if the weather is cool or hot or wet or dry, gardeners must do battle with weeds. Despite having a number of weapons to fight this battle, this year the weeds have won the war at my place. Between torrential rains, heat waves and ravenous mosquitoes, I must confess to nearly giving up. But I have renewed my efforts by putting myself on a weeding exercise schedule. That’s right, weeding is good exercise! […]
Although recent rains have relieved many gardeners from their watering chores, the respite is sure to be temporary. Seasonal thunderstorms may deluge some gardens with water while other areas, even those close by, may stay fairly dry. Most garden plants will need 1-1.5 inches of water per week to maintain healthy leaves, flowers and fruit. When Mother Nature does not provide enough, it’s up to the gardener to supply the rest. When you do need […]
While many of summer’s perennials are winding down for autumn, you can refresh your garden’s color with garden mums. Colors ranges from many shades of yellow, orange, red, purple, bronze, pink and white. The flowers themselves come in many different forms, from spider types with long, narrow petals to cushion types that have wider, more compact flowers. Some mums are bred as outdoor garden plants, but many are bred as florist-potted plants, meant to be […]
pecies can get too much of a good thing. When foliage or fruit is exposed to excessive sunlight, plant tissue can get a bit of sunburn, generally referred to as sunscald. Sunscald is often exacerbated by high temperature and drought. Sunscald symptoms will appear as yellow or white lesions on foliage and/or fruits. The lesions eventually may turn brown and/or shrivel. Foliage that is commonly affected includes impatiens, hosta, rhododendron, garden beans, peas, peppers and […]
The early arrival of summer’s steamy weather is tough on garden plants and their gardeners. It is really difficult to stay motivated to keep up with garden chores when you’re already dripping with perspiration by 9 a.m.! Although the weeds, insects, diseases and critters don’t seem to have any trouble thriving in this weather, some vegetable crops have trouble producing when under stress. Tomatoes, peppers, melons, squash, pumpkins, cucumbers and beans often drop their blossoms […]
Eager tomato-growers having lovingly nurtured seed to fruit have anxiously awaiting their first ripe gem. But, alas, a black leathery spot appears at the base of the fruit. Blossom-end rot is thankfully not an infectious disease but a frustrating disorder of the fruit. The black scar tissue thought to be caused by a deficiency of calcium in the developing fruit is usually brought on by extreme fluctuations in soil moisture. This year we sure had […]
If you live in the Midwest, you are likely familiar with the summer-blooming shrub commonly called Rose–of-Sharon, but you may not know it by its other common name – shrub althea. You may not be aware that it is a Hibiscus, that its scientific name is Hibiscus syriacus or that it belongs to the Mallow family, Malvaceae. Rose-of-Sharon is a large shrub, reaching up to 12 feet in height and nearly that in spread. The […]
Many gardeners, myself included, have had their lovely flowers flattened by hail in recent weeks. Trees and shrubs have had many leaves ripped from the stem, leaving a carpet of drying foliage on the yard and in the house gutters. And it seems that we’re not out of the woods yet, as more storms are predicted in coming days. So what can you do to help plants recover from such damage? The answer depends on […]
