Pyrus calleryana: cultivo, suelo necesario, riego...

Tema en 'Peral de flor (Pyrus calleryana)' comenzado por Chusyomisma, 2/2/09.

  1. Alguien me puede ayudar respecto a las características del Pyrus calleryana??

    Necesito saber cómo es el suelo que necesita, el riego y el sistema radical.
  2. Re: Pyrus calleryana

    Seguro que Google puede ayudarte.

    Yo en principio te puedo decir que se adapta a todo tipo de suelos, incluyendo calcareos, y que de riego solo requiere en épocas de calor aportes una o dos veces por semana cuando es joven, después le basta con la lluvia. Naturalmente esto del riego es modificable según el clima y suelo.

    Del sistema radical ni idea, pero dado su porte y rusticidad, yo diría que debe ser más profundo que ancho.

    Gracias okuspocus, almenos eres el único que me ha contestado!!

    Pero el tipo de información que pedía era algo más técnica. Se trata de un árbol para incluir en un proyecto, por lo que en los anejos debe estar toda la información detallada. Y aunque es de agradecer tus comentarios, no me sirven de mucho, pues es información muy ambigua, y yo necesitaba algo más concreto, ¿me entiendes?

    De todos modos, repito: gracias!

    Hola Chusy, te dejo una info que me paso el tio Goguel, espero que te sirva:

    Pyrus calleryana ‘Aristocrat’
    Figure 1. Young ‘Aristocrat’ Callery Pear.
    ‘Aristocrat’ Callery Pear
    Edward F. Gilman and Dennis G. Watson
    ‘Aristocrat’ Callery Pear quickly grows 35 to 45
    feet high and 30 to 35 feet wide, with widely-spaced,
    upright-spreading, thornless branches (Fig. 1). The
    more dominant trunk and open form of ‘Aristocrat’
    Callery Pear helps to make it less susceptible to wind
    and ice damage than ‘Bradford’. Branch angles are
    wider and lateral branches grow at a slower rate than
    on ‘Bradford’, therefore the branches are better
    attached to the trunk. In spring before the new leaves
    unfold, the tree puts on a brilliant display of pure
    white flowers which, unfortunately, do not have a
    pleasant fragrance. The leaves emerge as red/purple,
    then become 1.5 to 3 inches long, glossy green with
    wavy margins and a red blush. They turn red again in
    fall before dropping. The small, pea-sized, red/brown
    fruits which form are quite attractive to birds and other
    wildlife, and mummify on the tree persisting for
    several months to a year. Planting two or more
    cultivars of Callery Pear together could increase fruit
    Scientific name: Pyrus calleryana ‘Aristocrat’
    Pronunciation: PIE-rus kal-ler-ee-AY-nuh
    Common name(s): ‘Aristocrat’ Callery Pear
    Family: Rosaceae
    USDA hardiness zones: 5 through 9A (Fig. 2)
    Origin: not native to North America
    Uses: container or above-ground planter; large
    parking lot islands (> 200 square feet in size); wide
    tree lawns (>6 feet wide); medium-sized parking lot
    islands (100-200 square feet in size); medium-sized
    tree lawns (4-6 feet wide); recommended for buffer
    strips around parking lots or for median strip plantings
    in the highway; screen; shade tree; small parking lot
    islands (< 100 square feet in size); narrow tree lawns
    (3-4 feet wide); specimen; sidewalk cutout (tree pit);
    residential street tree; tree has been successfully grown
    in urban areas where air pollution, poor drainage,
    compacted soil, and/or drought are common

    Trunk/bark/branches: bark is thin and easily

    pedestrian clearance beneath the canopy; not
    particularly showy; should be grown with a single
    leader; no thorns

    or diseases which can affect tree health or aesthetics
    Planted commonly as a street tree or in parking lot
    islands, it is also quite suited for downtown tree pits
    due to its urban tolerance. Like ‘Bradford’ pear, it is
    able to tolerate small soil spaces. It looks great
    located along a street on 20 to 25-foot-centers and
    creates a ‘corridor’ for traffic flow.
    The major problem with the ‘Bradford’ pears has
    been too many upright branches growing too closely
    together on the trunk which leads to branch breakage
    and splitting. ‘Aristocrat’ appears to be mostly free of
    this problem, but has been shown to be more
    susceptible to fire blight than ‘Bradford’, particularly
    in evaluations conducted in the south. Pruning the
    trees early in their life to space lateral branches along
    a central trunk should be all that is needed to ensure a
    strong, well-structured tree. Only buy trees with well-
    spaced branches.
    Callery Pear trees are shallow-rooted and will
    tolerate most soil types including alkaline and clay, are
    pollution-resistant and tolerate drought and wet soil
    well. ‘Aristocrat’ is a very adaptable tree suited for
    downtown and other restricted soil spaces.
    Aphids cause distorted growth and deposits of
    Scales occasionally affect pears.
    Several borers may attack pear. Keep trees
    healthy to prevent attacks.
    ‘Aristocrat’ pear is very susceptible to fire blight.
    This disease can devastate a planting. Tips of infected
    branches appear scorched and burnt. The leaves
    droop, turn brown, but remain hanging on the tree.
    The bacteria wash down the branch and form cankers.
    Bark inside the canker often shreds and peels. When a
    canker girdles a branch, that branch dies. Prune out
    infected branches well below the infected area
