General Rules of Thumb for Pruning Flowering Shrubs *Prune spring flowering shrubs right after they bloom *Lilac ‘Red Pixie’ 4’-6’ tall Sun Z 2-7. *Forsythia SHOW OFF ‘Sugar Baby’ Sun – Part Shade 1.5’-2.5’ tall Spring Z 5-8 2. Prune summer and fall flowering shrubs in late winter or early spring while they are still dormant or just breaking dormancy *For variegated plants, remove non-variegated leaf branches *For suckering shrubs (i.e., Forsythia, Kerria, Lilacs), remove some, or all suckers, by cutting the sucker off just beneath the soil surface *Rose of Sharon ‘Sugar Tip’ (Hibiscus syriacus) Sun late Summer 8’-12’ tall Z 5-8 Variegated leaves Sterile 3. Pollarding is when shrubs are cut to the main stem or trunk, ultimately controlling the height of the plants. This is different from coppicing because the trees and shrubs are not cut at ground level, but much higher, usually around six feet. Do this pruning in late winter or early spring while plants are dormant (Horticulture magazine) 4. Coppicing is a pruning technique that shrubs to ground level, causing new shoots to grow rapidly from the base during growing season. Prune hard in late winter or early spring when plants are dormant 5. For each of the featured flowering shrubs I will note pruning recommendations as follows: Prune 1: Prune in late winter or early spring Prune 2: Prune after spring bloom NOTE: Some shrubs seldom need pruning. Best to buy shrubs that mature to the height and width you want! 6. Many of today’s featured flowering shrubs are good candidates for growing in containers. *Buddleia LO & BEHOLD ‘Pink Micro Chip’ Sun 1.5’-2’ tall Summer Z5-9 Non-invasive Prune 1 7.

Tricks for getting bigleaf or Mountain Hydrangea to bloom even after wicked cold winters! Grow shorter varieties like those in the Let’s Dance or Cityline series. Flower buds more likely to be protected by snow. Or plant them in containers and then overwinter containers in unheated garages, sheds, barns. Or grow them in nursery pots that are planted in the landscape, lifted for winter storage, and replanted in spring 41.

  • County Line Nursery Fiesta St. John's Wort
    Fiesta St. John's Wort Hypericum calycinum 'Fiesta' Height: 12 inches Spread: 3 feet Spacing: 30 inches Sunlight: Hardiness Zone: 4 Description: A stoloniferous groundcover variety with stunning lemon-yellow and blue-green variegated foliage, that takes on peachy tones in cool weather; yellow flowers in mid-summer; a versatile shrub, that is a fantastic addition to the color garden; adaptable Fiesta St. John's Wort foliage Photo courtesy of NetPS Plant Finder Ornamental Features Fiesta St. John's Wort has masses of beautiful yellow buttercup flowers at the ends of the branches from early to mid summer, which are most effective when planted in groupings. The flowers are excellent for cutting. It has attractive lemon yellow-variegated deciduous bluish-green foliage with hints of peach throughout the season. The oval leaves are highly ornamental but do not develop any appreciable fall color. The fruit is not ornamentally significant. Landscape Attributes Fiesta St. John's Wort is a dense multi-stemmed deciduous shrub with an upright spreading habit of growth. Its relatively fine texture sets it apart from other landscape plants with less refined foliage. This shrub will require occasional maintenance and upkeep, and should only be pruned after flowering to avoid removing any of the current season's flowers. Deer don't particularly care for this plant and will usually leave it alone in favor of tastier treats. It has no significant negative characteristics. Fiesta St. John's Wort is recommended for the following landscape applications; - Mass Planting - General Garden Use - Groundcover - Container Planting Planting & Growing Fiesta St. John's Wort will grow to be about 12 inches tall at maturity, with a spread of 3 feet.

  • Deciduous Woody Groundcovers, Page 1
    Deciduous Woody Groundcovers, page 1 Deciduous Woody Groundcovers Low-growing shrubs and woody plants provide attractive, protective cover for gardens, slopes and many difficult sites. When most people think of groundcovers, they think of low-growing perennials, such as periwinkle (Vinca minor), Bugleweed (Ajuga reptans), Sweet Woodruff (Gallium odoratum) or Lily-of-the-Valley (Convalaria majallis). But deciduous woody shrubs growing up to 4 feet tall can also fill the groundcover niche in a variety of soil and sun conditions, according to research at Cornell University’s Urban Horticulture Institute. Good reasons to plant Matching the right deciduous woody species to the site – and carefully planting and caring for them – can provide many benefits: • Reduced mowing expenses when used to replace turfgrasses, • Better erosion control when used to replace species poorly adapted to shady sites, steep slopes or other challenging locations. • Reduced competition from turfgrasses and less damage from foot traffic, mowers and string trimmers when used around trees. • Transpirational cooling and more porous ground surfaces to improve drainage when used as an alternative to pavement. • Habitat and food for wildlife. Also, many deciduous woody groundcovers perform best in full sun and grow up to 4 feet tall, while many of the common herbaceous perennial groundcovers are low- growing and perform better in part shade or shade. Many of the species best-suited for deciduous woody groundcover plantings would never be considered spectacular specimen plants. Up close or planted singly, some are rather plain. But planted in masses and viewed from a distance, well-designed plantings can be aesthetically quite pleasing.

Biological control of weeds and fire management in protected natural areas: are they compatible strategies? Biological Conservation, Vol. 77, Issue 2-3, pp. 135–141. Author’s abstract: Biological control of weeds has been traditionally associated with pastoral or cultivated land-use systems. Recently though, there has been increasing discussion of the possibility of biological control of weeds that have invaded national parks and native forests. However, a completely different set of management strategies applies in such land-use systems, the aims of which may conflict with those of classical biological control. In Australia, one such practice is the use of regular prescription burning to control the incidence and severity of wild fires. This paper reports data collected between 1981 and 1987 on an infestation of St John's wort (Hypericum perforatum), and its biological control agent, Chrysolina quadrigemina, in eucalypt forest that was burnt twice during the study period. The fires both promoted development of the weed population and retarded that of the control agent. However, a subsequent indirect effect of fire was to favour population build-ups of C. quadrigemina and a recently released agent, Aphis chloris, through increased plant nutrient levels.

  • Morphological and Phytochemical Diversity Among Hypericum Species of the Mediterranean Basin

(St. John’s wort, Hypericaceae) includes more than 480 species that occur in temperature or tropical mountain regions of the world. Monographic work on the genus has resulted in the recognition and description of 36 taxonomic sections, delineated by specific combinations of morphological characteristics and biogeographic distribution. The Mediterranean Basin has been recognized as a hot spot of diversity for the genus Hypericum, and as such is a region in which many endemic species occur. Species belonging to sections distributed in this area of the world display considerable morphological and phytochemical diversity. Results of a cladistic analysis, based on 89 morphological characters that were considered phylogenetically informative, are given here. In addition, a brief overview of morphological characteristics and the distribution of pharmaceutically relevant secondary metabolites for species native to this region of the world are presented. _____________________________________________________________________________________________________________
