If your tomatoes dropped their blossoms instead of setting eagerly awaited fruits, you’re not alone. The weather for the last month or so has been quite inhospitable for tomato fruit set. Most plants have experienced colder temperatures than what is needed for pollination to be successful. In stark contrast, we had a brief period of unseasonably warm weather. Warm-season crops, which include tomatoes, peppers, beans, squash, cucumbers and melons, require temperatures above 55 […]
Want to add a little drama to your garden? Need to perk up a shady bed? Big, bold foliage can make a long-season statement! Foliage often provides the bones of the garden, but it can also take center stage with dramatic size, color variegation, texture and shape. Many of the following plants have beautiful flowers, in addition to big, bold foliage. Acanthus spinosus (spiny bears-breeches) features spiny foliage accented by purple or white […]
As temperatures warm up in late spring, many home gardeners move houseplants to outdoor living areas such as porches, patios, and sunrooms. Most indoor plants can flourish outside if given proper attention. First, have the patience to wait until temperatures are dependably warm. Most houseplant species originated in the tropics and are sensitive to temperatures below 55 degrees Fahrenheit. Be prepared to bring the plants back indoors on cool nights. Gradually acclimate the plants by […]
If your lettuce is bitter and your spinach is going to seed, don’t be disheartened. There are some vegetables that enjoy the heat of summer. The cucurbits, or vine crops, include such favorites as cucumbers, squash, melons and pumpkins. Although each of these taste quite different, their culture is very similar. Cucurbits are warm-season crops that are notorious for taking over large amounts of garden space. Fortunately, plant breeders have developed the so-called “bush-type” plants […]
We humans can be so difficult to please. If plants flower when we want them to, we call it blooming. But if plants flowers when we don’t want them to, we call it bolting. Flowering is an undesirable trait when growing rhubarb; therefore, bolting describes the event. Gardeners frequently ask why their rhubarb is bolting. Well, if you think of it from the plant’s perspective, it is just a part of the plant’s natural life […]
Gardeners have long used manure from various farm animals to fertilize and enrich their soil. However, recent public awareness of food-borne illnesses has left many gardeners wondering if using manure is safe. There are a number of pathogens, including E. coli, salmonella, and listeria that can be transferred to humans from animal manure. Some animal manure may also contain parasites, such as roundworms and tapeworms. If fresh manure is applied to the garden […]
Although some dedicated gardeners may have already planted their seed potatoes, for most of us, the ground has been a little too soggy. Some gardeners aim for planting on or around St. Patrick’s Day, while others of us will be lucky to have them planted by Mother’s Day! Potatoes are considered to be cool-season plants and can be planted just as soon as the ground has thawed and dried enough to safely work the soil. […]
Some landscape plants produce vigorous, upright stems that become troublesome as they out compete better-formed branches and shade out the rest of the plant. These remarkably fast growing upright stems are called “suckers” if they come from the root system, and “watersprouts” if they originate from other stems. Ornamental crabapples are among the most notorious producers of these unwanted stems, but many other trees and shrubs can be afflicted, including contorted filbert, peach, apple and […]
The Perennial Plant Association has selected Dianthus gratianopolitanus Firewitch’ (Feuerhexe’) as its 2006 Perennial Plant of the Year. Also known as a cheddar pink, the perennial dianthus is an excellent choice for use as an edging plant, as a rock garden specimen, to soften retaining walls, and in container gardens. Firewitch’ has hot pink flowers that bloom profusely in mid to late spring, with some repeat bloom in summer and fall if you deadhead faded […]
It’s not unusual for Indiana weather to have trouble deciding what season it is. Recent warm spells have had many gardeners wondering what to do about bulbs — and, perhaps, a few other plants that are poking their foliage through the soil. As I write this article, temperatures started out in the 50s and are expected to drop to the upper 20s by tonight! Just what should gardeners do about daffodils, dianthus and daylilies poking […]
