Luffa are tropical, vining plants that produce large fruits similar to cucumbers. When young and small the fruit can be cooked and prepared like a summer squash. When the fruit mature, they have a rough, fibrous interior which is referred to as the sponge and is used to make a wide variety of products. Currently, luffa sponge products are most popular as personal care products and are readily available in the cosmetic and bath sections of department stores, discount stores, pharmacies, and specialty shops. This factsheet covers how to plant, harvest, and process luffa gourds in a temperate environment.
Many farmers and home gardeners have reported damage to vegetable and flower crops after applying horse or livestock manure, compost, hay, or grass clippings to the soil. The symptoms reported include poor seed germination; death of young plants; twisted, cupped, and elongated leaves; misshapen fruit; and reduced yields. These symptoms can be caused by other factors, including diseases, insects, and herbicide drift. Another possibility for the source of these crop injuries should also be considered: the presence of certain herbicides in the manure, compost, hay, or grass clippings applied to the soil.
Black cohosh is a member of the Ranunculaceae family. It is a native medicinal plant found in rich woodlands from as far north as Maine and Ontario, south to Georgia, and west to Missouri and Indiana. In North Carolina it can be found at elevations up to 4,000 feet and is most common in the western part of the state. It is an herbaceous perennial reaching a mature height of over four feet tall and can grow 18 to 22 inches per month during the growing season.
This guide provides techniques for small-scale outdoor cultivation of shiitake mushrooms on logs. Tree selection and log preparation, spawn selection, inoculation, fruiting, pest and disease management and harvesting are covered.
If treated properly, many herb plants will survive in the garden for a number of years. Others are sensitive to frost or severe cold weather and must be brought indoors, protected, or replanted each year. Annual herbs will be killed with the first hard frost in the fall. Remove dead plants in order to minimize overwintering insects and disease problems. Some frost sensitive herbs, such as basil and geranium, can be brought indoors for the winter. Take cuttings to root or pot the entire plant.
This publication specifically discusses fresh-market basil, examining the selection, production, harvesting and marketing of the product.
Pole beans are grown commercially in the mountain counties and, on a limited scale, in a few of the eastern counties. They are produced in home gardens throughout the state. Pole beans are grown for their distinctive flavor, long pods, high yield, long harvesting season, and high price.
Herbs should be harvested when the oils responsible for flavor and aroma are at their peak. Proper timing depends on the plant part you are harvesting and the intended use. Herbs grown for their foliage should be harvested before they flower. While chives are quite attractive in bloom, flowering can cause the foliage to develop an off-flavor. Harvest herbs grown for seeds as the seed pods change in color from green to brown to gray but before they shatter (open). Collect herb flowers, such as borage and chamomile, just before full flower. Harvest herb roots, such as bloodroot, chicory, ginseng, and goldenseal, in the fall after the foliage fades.
This publication offers fertilizer suggestions for a variety of crops, including field, pasture and hay crops, tree fruit, small fruit, ornamental plants and vegetable crops.
This publication discusses the best techniques for growing quality ginseng. It includes descriptions and stages of growth, and information on general culture, site preparation and mulching.
This publication provides introductory information about growing and wild-harvesting medicinal herbs in North Carolina. The practices suggested here apply to all raw herbal plant material used to make herbal products, dietary supplements, cosmetics, foods, and drugs.
With the increasing diversity of North Carolina agriculture, it is important to document and assess the presence of the commodities produced in the state. Crop data are publicly maintained on only the top 20 or so specialty crops, yet state and federal decisions impact hundreds of individual crop species. Because little information is available for most specialty crops, it must be gleaned from many different sources.
A good source of water is a necessity for producing quality vegetables. During periods of drought, crop diversification and mulches can be used to cope with drought situations, but nothing will substitute for the timely application of water. This publication covers some guidelines for irrigation systems to help offset periods of drought in the Southeast United States.
