‘Gloria’ is a large, yellow-fleshed, freestone, non-melting peach that ripens around mid-August. This late blooming variety, developed by Rutgers New Jersey Agricultural Experiment Station is unique because of its very attractive color, low acidity, distinctive flavor, and very firm flesh. Previously we saw that letting ‘Gloria’ hang longer lets fruit get sweeter and larger. Firm flesh allows for relatively longer hang time on the tree after fruit has reached commercial maturity, providing greater flexibility in harvest scheduling and shipping to growers as well as buyers. We have estimated how long it is safe to let ‘Gloria’ fruit remain on the tree and in cold storage without affecting fruit quality. Studies in two orchards in Southern NJ indicated that; [Read more…]
Getting the Upper Hand on Virginia creeper
Virginia creeper (Parthenocissus quinquefolia) is a perennial woody vine that climbs on other objects or trails along the ground. It is a common weed of orchards, vineyards and blueberry plantation. It is best identified by the typical palmate leaf with 5 leaflets that originate from the same point (picture 1). Virginia creeper will produce many tendrils with adhesive disks at their tips that will allow the vine to climb upward and to attach to any support. It can grow under a wide range of conditions including dry sandy or moist organic soils, sunny or shady sites, and is tolerant to high salinity. Plants will often establish through seeds dropped by birds who consumed the small blue berries in fall, but also by the spread of crawling stems that will produce new roots in contact with soil (picture 2). Virginia creeper is often confused with Poison-Ivy (Toxicodendron radicans). However, poison-ivy has 3 leaflets instead of 5 for Virginia creeper and lacks the tendrils and adhesive disks.
As a perennial weed, Virginia creeper will be tough to control as it can easily regrow after foliar injury from its extensive underground root system. When established, Virginia creeper will most often not be controlled with a single herbicide application, and multiple applications will be necessary to achieve acceptable control. Only nonselective postemergence herbicide (glyphosate) must be used to suppress or control this weed. In order to increase the efficiency of postemergence applications during the growing season, remove the vine from their support during winter pruning and lay it on the ground or plan a “cut stump” treatment during the growing season. Do NOT “prune out” the vine during the dormant season.
Spot treatment. Glyphosate may be applied in mid- to late summer after vine flowers in early July until the first signs of fall color appear in the foliage. Good growth and maximum leaf area is needed at the time of herbicide application during the summer. Wet a minimum of 50 percent of the weed foliage with a 1% glyphosate solution (1.25 oz of 4.5lb acid material per gallon of water) for effective control. For best control, don’t apply on stressed/wilted weeds.
Cut stump treatment. Best results are often obtained in late summer and early fall, but before fall color is observed in the foliage. Apply a 1% glyphosate solution to the cambial areas (inner bark area) of the stump of woody plants IMMEDIATELY after cutting. Cut and treat stumps only when the Virginia creeper is actively growing and not under stress.
WARNING. Injury due to root grafting may occur in adjacent plants. Do not treat cut stumps if there is a possibility of root grafting to desirable vegetation. Do NOT allow contact with green bark, trunk wounds, leaves, or root suckers of blueberry bushes.

Ultra-Niche Crop Educational Sessions Offered
Rutgers Cooperative Extension is offering a series of workshops for new and beginning farmers. The series, sponsored by a grant from the USDA-NIFA Beginning Farmer and Rancher Development Program, is part of the Rutgers Ultra-Niche Crops Project. Ultra-Niche Crops are exceptionally high value crops that can be grown on small acreage. The program is geared towards anyone who is interested in making more money off less land. If you are a new or beginning farmer, or an experienced farmer interested in learning about niche crops, then join the mailing list for more information.
The first class on growing and marketing Plasticulture Strawberries will be held on September 28th. More details and registration are now available. To speak with the project director, contact County Agricultural and Resource Management Agent Jenny Carleo by email (ko at rutgers dot edu) or by phone at 609-465-5115 x607.
