Growing and caring for Pyrus calleryana

Pyrus calleryana,  commonly known as the flowering pear or Callery pear tree, owes its name to the Italian-French missionary and sinologist Joseph-Marie Callery, who in the 19th century was the one who sent the first specimens to Europe from China, where they originate. . In case you did not know what a sinologist was, he is that person who is dedicated to the study of the Chinese world.

From the Rosaceae family , this small deciduous tree is prized for its ornamental value, it looks beautiful at any time of the year. In spring for its spectacular, abundant and aromatic flowering, and in autumn for the intense color of its leaves. It is for this reason that it is increasingly common to see it in private gardens, but also in parks, sidewalks and garden areas in cities, since it resists environmental pollution well.

CHARACTERISTICS OF  PYRUS CALLERYANA

With a straight and majestic bearing, this tree can reach 20 meters in height , developing a compact column-shaped crown when the specimen is young and that becomes conical as it grows.

TRUNK AND LEAVES

The trunk of this species is usually very straight and grayish in color. From its branches sprout simple and oval leaves between 4 and 7 centimeters long of a dark green tone that is lighter on the underside. During the fall , before falling, the green foliage turns into different shades, yellow, orange, red and scarlet that are quite a spectacle.

FLOWERS AND FRUITS

The flowering of the Pyrus Calleryana is also spectacular. At the beginning of spring and before the leaves sprout, it is filled with small white flowers with five petals, grouped in corymbs or bouquets that give off a sweet and intense aroma that is very attractive to bees. The fruits emerge from them, small pears barely 1 centimeter in diameter, round in shape and brown in color when ripe. They are not edible, but they attract birds and serve as food for them.

VARIETIES

Being a tree for almost exclusively ornamental use, there are varieties with subtle differences in size, resistance or in the color and aroma of the flowers. They are as follows:

  • Pyrus calleryana  Aristocrat
  • Pyrus calleryana  Autumn Blaze
  • Pyrus calleryana  Bradford
  • Pyrus calleryana  Whitehouse 
  • Pyrus calleryana  Cleveland Select
  • Pyrus calleryana  Capital
  • Pyrus calleryana  New Bradford
  • Pyrus calleryana  Redspire

Of all of them, the most used for urban ornamentation is Bradford, although the most resistant is Cleveland Select .

CARE OF THE FLOWERING PEAR TREE

It is a fairly resistant tree and adapts relatively easily to any type of soil , even to salinity on the second coastline . Although it prefers temperate climates, it can withstand, with little damage, temperatures as low as -18 ° C in its winter slumber.

It is not too difficult to keep the flowering pear tree in optimal conditions, although it does not hurt to follow some recommendations to enjoy a healthy and leafy specimen.

LOCATION AND SUBSTRATE

It is a tree that needs to be in full sun or in semi-shady areas , so it should always be planted outdoors and at a minimum distance of about four meters from other plants that are tall and can overshadow it.

Although a pot is not the ideal location for the flowering pear tree, we can keep it in one of them for the first few years, and then transplant it to its final location. During these first years in a pot, a universal substrate will be enough to maintain it.

In the garden it admits almost all types of soil, regardless of whether it is sandy or clayey as long as it has good drainage and is fertile .

IRRIGATION OF THE PYRUS CALLERYANA

Although it is quite resistant to specific periods of drought and we can wait until the land is completely dry to water, the flowering pear tree will grow much healthier and more leafy if we try to water it with a moderate frequency, being enough one watering per week from the beginning of the fall through the end of spring and 3 to 4 times a week during the summer.

PASS

The flowering pear tree is a fast-growing tree, so it does not usually require fertilizing, but an extra supply of nutrients once a year and at the beginning of spring through organic fertilizers such as manure , will provide enough nutrients for development. optimal and constant.

If you have it in a pot you should use some liquid fertilizer such as guano, mixed with the irrigation water.

PLAGUES AND DISEASES

This is a very resistant and tolerant species, so it is not usual for it to be affected by pests or diseases that pose a danger.

Although it occurs rarely, it can be affected by aphids , mites and caterpillars, which are treated with specific insecticides for each species.

In conditions of excessive environmental or substrate humidity, diseases such as pear blight or those caused by fungi or gray mold can affect it , which can be avoided by taking care of the frequency of irrigation.

MULTIPLICATION OF  PYRUS CALLERYANA

It is so easy to multiply the flowering pear tree by seeds that in some places it is already considered an invasive species. The birds, which feed on its fruits, defecate the digested seeds, causing them to proliferate very easily.

However, if you have Pyrus calleryana seeds   you have to know that these seeds require going through an intense cold before germinating.

If you live in an area where winters are very cold, you will only need to plant it in a pot of about 20 cm. in diameter filled with universal substrate, water it when you see that the substrate is too dry and wait for it to germinate.

But if you live in a warm area, before being able to sow them, you must subject the seeds to artificial stratification in the fridge, in a container with a lid and covered with moistened vermiculite for four months, remembering to open the container from time to time to renew the air. and that no fungus occurs . After this time they will be ready to go to a seedbed and germinate , giving way to a seedling that you can transplant to its final location during spring.
