Salt-spray Tolerant Groundcovers, Shrubs, and Trees for Eastern Long Island

Aerial salts carried by on-shore breezes, fog, and wind can injure plants sensitive to salt deposition. The plants listed below have displayed either high or moderate tolerance to salt spray. Most species listed have displayed high tolerance ( little to no damage). Those species noted as having moderate tolerance may show signs of salt injury (tip dieback, foliar damage, reduced growth). Moderately-tolerant species should be planted in areas away from direct salt-spray exposure. Salt-spray tolerance applies to aerial deicing salts as well. The plants listed were chosen because they are relatively disease and pest resistance (unless noted), and well-suited for eastern Long Island.

    Technical Note 30: Ability of Pacific Northwest Shrubs to Root From

    TECHNICAL NOTES _____________________________________________________________________________________________ U.S. DEPT. OF AGRICULTURE NATURAL RESOURCES CONSERVATION SERVICE PORTLAND, OREGON DATE: September 2002 PLANT MATERIALS TECHNICAL NOTE NO. 30 Ability of Pacific Northwest Native Shrubs to Root from Hardwood Cuttings (with Summary of Propagation Methods for 22 Species) Dale C. Darris Conservation Agronomist Corvallis Plant Materials Center SUMMARY There is a need for additional information on how well native shrubs root from hardwood cuttings. First, nurseries are seeking to refine vegetative propagation techniques. Second, practitioners in the fields of riparian/wetland restoration and streambank stabilization are looking for species that are easy to root from unrooted dormant material that will provide cost competitive alternatives to native willows (Salix spp.) and redosier dogwood (Cornus sericea) for direct sticking of cuttings and soil bioengineering practices. The purpose of this work was to screen 15 shrubs indigenous to the Pacific Northwest USA for their ability to root from hardwood cuttings with and without a rooting compound in a greenhouse mist bench, well drained field, nursery bed, and saturated substrate (artificial pond). If a species roots easily, it has greater potential for planting as dormant cuttings, live stakes, or whips directly on a revegetation site, and may warrant further evaluation for fascines, brush mattresses, or other soil bioengineering practices. Based on the rooting ability of hardwood cuttings made from 1 (or 2) year old wood, those species with good potential include black twinberry (Lonicera involucrata), salmonberry (Rubus spectabilis), common snowberry (Symphoricarpos albus), and Pacific ninebark (Physocarpus capitatus). Coyote brush (Baccharis pilularis) and red elderberry (Sambucus racemosa) have fair potential. Indian plum (Oemlaria cerasiformis), mock orange (Philadelphus lewisii), and red flowering currant (Ribes sanguineum) may apply under limited circumstances, select uses, or ideal conditions.

    Tools of the Cabinetmaker, but Also Like the Cartwright, the Hatchet (Handbeil) and the Drawknife (Schneidemesser)

    CHAPTER FIVE The Chairmaker The chairmaker bears the name in common with English chairmakers presumably because his trade is originally transplanted from England to Germany, or because several types of chairs that are made in his workshop have been common first in England. In the making of chairs, the settee (Canape), and sofa, he wields not only the plane and other tools of the cabinetmaker, but also like the cartwright, the hatchet (Handbeil) and the drawknife (Schneidemesser). I. In most regions, and especially in the German coastal cities, chairmakers make their chairs out of red beech wood, in Magdeburg out of linden wood, and in Berlin out of serviceberry wood (Elsenholz). Red beech is lacking in our area, and the cabinetmaker, who before the arrival to Berlin of chairmakers that made wooden chair frames, chose therefore serviceberry wood in place of red beech. Likewise the chairmakers, when they arrived in Berlin, found that circumstances also compelled them to build their chairs out of serviceberry wood. If the customer explicitly requires it, and will pay especially for it, they sometimes build chairs out of walnut, plum wood, pearwood, and mahogany wood, and for very distinguished and wealthy persons out of cedarwood. The chairmaker obtains the serviceberry wood partly in boards that are one to five inches thick and partly in logs. The farmer in the [town of] Mark Brandenburg brings this wood, partly in logs and also in boards, to Berlin to sell, but the strongest and best comes from Poland. If the wood has not sufficiently dried when purchased by the chairmaker it must stay some time longer and properly dry.

I have organized these design considerations into four principles that archery clubs and land planners can utilize. Observing sensitivity to the environment, providing a layout for safe shooting, making the space comfortable, and programming inclusive spaces makes a range that serves its community well. These principles are to explain concisely how a range can be made not only to accommodate archers but also to exist harmoniously with neighboring land as well as function as a valuable community building asset. Finally, an example design treatment to the Yolo Bowmen Archery Range of Grasslands Regional Park will help to clarify the principles set forth in

Both fruits have performed Amuch better in Texas than nectarines, almonds, sweet cherries, and Prunus hybrids because they are less susceptible to disease, varmints, and crop loss due to premature blooming. Plums The plum tree has white flowers and sets fruit on buds from previous season’s growth (Fig. 1). Usually Figure 1. A plum orchard in full bloom. the fruit has a dusty white coating or wax bloom that is easily rubbed off (Fig. 2). Plums can be sweet to tart; the skin is typically quite tart. The two main species used in the United States are the European plum, Prunus domestica, and the Japanese plum, Prunus salycina. The European plum includes varieties such as ‘Stanley’, which is grown for fresh fruit and often dried for use as prunes. These varieties have produced poorly in Texas because they require cold climates and are susceptible to fungal diseases such as brown rot. The varieties adapted to Texas are usually hybrids Figure 2.

  • Landscaping Near Black Walnut Trees

    Landscaping Near Black Walnut Trees

    Selecting juglone-tolerant plants Landscaping Near Black Walnut Trees Black walnut trees (Juglans nigra) can be very attractive in the home landscape when grown as shade trees, reaching a potential height of 100 feet. The walnuts they produce are a food source for squirrels, other wildlife and people as well. However, whether a black walnut tree already exists on your property or you are considering planting one, be aware that black walnuts produce juglone. This is a natural but toxic chemical they produce to reduce competition for resources from other plants. This natural self-defense mechanism can be harmful to nearby plants causing “walnut wilt.” Having a walnut tree in your landscape, however, certainly does not mean the landscape will be barren. Not all plants are sensitive to juglone. Many trees, vines, shrubs, ground covers, annuals and perennials will grow and even thrive in close proximity to a walnut tree. Production and Effect of Juglone Toxicity Juglone, which occurs in all parts of the black walnut tree, can affect other plants by several means: Stems Through root contact Leaves Through leakage or decay in the soil Through falling and decaying leaves When rain leaches and drips juglone from leaves Nuts and hulls and branches onto plants below. Juglone is most concentrated in the buds, nut hulls and All parts of the black walnut tree produce roots and, to a lesser degree, in leaves and stems. Plants toxic juglone to varying degrees. located beneath the canopy of walnut trees are most at risk. In general, the toxic zone around a mature walnut tree is within 50 to 60 feet of the trunk, but can extend to 80 feet.
