HOW TO GROW AND CARE FOR OUR PLANTS
The genrePandorea includes a few species of evergreen climbing plants, much appreciated both for their flowers and for their particularly attractive foliage.
Species: see the paragraph on "Main species"
The genre Pandorea of the family of Bignoniaceae it includes evergreen climbing plants native to the rainforest of Malaysia, Papua, Australia and New Caledonia, located from sea level up to 3000 m of altitude.
The stems are woody and very branched. The leaves are mostly opposite or verticillate, pinnate with up to 9 pairs of dark green leaflets. The flowers are tubular, formed by five lobes, with the terminal part expanded, gathered in racemes or panicles in the terminal part of the branch and are particularly fragrant. The fruits are wooden pods in the shape of a boat, about 8 cm long, spreading 2 cm and containing numerous winged seeds of paper consistency.
In areas with a mild climate Pandorea they are grown outdoors to make pergolas as climbing and hanging plants for their beautiful decorative effect.
There are few species in the Pandorea genus among which we remember:
TherePandorea pandorana (Bignonia pandorana or Tecoma australis) native to Papua and New Guinea is a very vigorous climber that produces many thin, particularly branched stems.
The leaves are typical of the species, pinnate (formed by 6 pairs of small leaves) up to 10 cm long. It blooms in winter and spring producing lovely creamy yellow tubular flowers with red streaks. The flowers are gathered in mostly terminal racemic inflorescences.
TherePandorea jasmionoides (Bignonia jasminoides) is a beautiful climber native to Australia with twisted and very branched stems. The leaves are pinnate and composed of 5-9 leaflets of a beautiful glossy green color while the flowers are tubular with the expanded terminal part of a whitish streaked with pink in the throat, gathered in panicle inflorescences.
There are numerous hybrids among which we remember: Pandorea jasminoides 'Alba' with white flowers; Pandorea jasmionoides 'Lady Di' white confori with an orange-yellow throat; Pandorea jasminoides'Rosea' with pink flowers and a dark pink throat; Pandorea jasminoides'Rosea Superba' with pink flowers, a deeper pink throat and red streaks.
There Pandorea it is a delicate plant that in mild climate areas can be grown outdoors, in full sun or in partial shade as a climbing or hanging plant to adorn pergolas or walls. In harsh climate areas it is preferable to grow it in pots to be brought into a protected environment during the cold season.
Optimal cultivation temperatures are between 18 - 25 ° C. Prolonged temperatures below 5 ° C begin to create serious problems for the plant.
It is important to understand the Pandorea of tutors to it can anchor itself given its climbing posture.
Throughout the spring-summer period the plant of Pandorea it should be watered in moderation avoiding water stagnation in the saucer. Better to irrigate with a little water but often.During the autumn-winter period it is necessary to wet with much more moderation.
TYPE OF SOIL - REPOT
There Pandorea it is repotted every year in spring using a good fertile soil which tends to be acidic rich in organic substance.
From spring and throughout the summer, administer it Pandorea with irrigation water once a month a good liquid fertilizer equally balanced in nitrogen (N), phosphorus (P) and potassium (K). It is also important that it also contains microelements, i.e. those elements present in minimal quantities (but still important for a balanced growth of the plant) such as iron (Fe), manganese (Mn), copper (Cu), zinc (Zn), boron (B), molybdenum (Mo).
Pruning is important for Pandorea to manage the plant. The optimal period is late autumn - early winter, because flowering occurs on the branches of the year.
The flowering period varies from species to species and we refer to them.
The multiplication of thePandorea occurs by cutting or by seed.
In choosing the technique to be adopted, it must be borne in mind that multiplication by seed has the disadvantage that, taking over the genetic variability, it is not certain that plants will be identical to the mother plants, in which case if you want to obtain a precise plant or not is sure of the quality of the seed, it is good to do the multiplication by vegetative parts.
MULTIPLICATION FOR TALEA
The 10-15 cm long cuttings are taken in summer by cutting them with an oblique cut immediately under a node.This type of cut is recommended as it allows to have a greater surface for rooting and avoids the accumulation of water on that surface.
Use a clean, sharp blade to avoid fraying the tissues and suitably disinfected, preferably with a flame, to avoid infecting the tissues.
After removing the lower leaves, the cuttings are placed in a compote formed by peat and coarse sand in equal parts.The pot is covered with a plastic bag put on a cap after placing sticks in the ground to keep the plastic away from the cuttings and have tightened the bag with an elastic to the pot, to avoid loss of moisture.
The cuttings are placed in an environment at about 18 ° C of temperature and every day they remove the plastic to control the humidity of the soil and eliminate the condensation that will have formed on the plastic. that the cuttings will have rooted. At that point, the plastic is removed permanently and the pot is placed in a brighter area, at the same temperature and waits for the cuttings to strengthen.Once they are large enough, they will be transplanted into the final pot and treated like adult plants.
MULTIPLICATION BY SEEDS
The seeds are planted in spring in a compost formed by fertile soil and coarse sand.The tray that contains the seeds should be kept in the shade, at a temperature around 13-18 ° C and it is essential that the soil remains constantly humid (use a sprayer for moisten the soil) until the moment of germination.
The tray must be covered with a transparent plastic sheet (or with a glass plate) which will guarantee a good temperature and avoid too rapid drying of the soil. The plastic sheet must be removed every day to check the degree of humidity in the soil and to remove the condensation that forms on the plastic.Once the seeds have germinated (usually after two weeks) remove the plastic sheet and move the box in a brighter location (not in direct sun).
It is important to eliminate the less vigorous plants to give space to the more robust ones.Once the new plants are large enough to be handled they are transplanted into single pots with a compote as indicated for adult plants and treated as such.
PARASITES AND DISEASES
The plant grows and blooms little
These symptoms could be due to poor light or too low temperatures.
Remedy: analyze how the plant was bred according to the indications given in this sheet and adjust accordingly.
Presence of aphids on the plant
On the plant it is possible to observe small animals ranging in color from white to yellow to green. These are aphids, or as they are commonly called lice.
Look at them with a magnifying glass and compare them with the photo on the side, they are unmistakable, you can't go wrong. They are generally located in the most tender parts of the plant (but not only). They are insects that can cause serious damage as they sting the tissues of the plant with their mouthparts and steal the lymph. In addition, they can transmit diseases (especially viruses) and their droppings are very hungry for numbers of other insects and fungi.
Remedy: treat the plant with specific pesticides readily available from a good nurseryman. These are generally systemic products, that is, they enter the plant's lymphatic circulation and are therefore absorbed by insects during feeding.
Presence of small reddish animals on the plant
If the leaves begin to turn yellow and after these manifestations they crumple, assuming an almost dusty appearance and fall, most likely there is an attack of red spider, a very annoying and harmful mite. Observing carefully you can also notice thin cobwebs especially on the lower page of the leaves.
Remedy: increase the humidity around the foliage as mites are favored by a dry environment. If with this system it is not possible to control them then it is necessary to intervene with specific acaricides easily available in a good garden center.If the plant is not particularly large, you can also try to clean the leaves to eliminate the parasite mechanically using a wet cotton swab. and soapy. After that the plant was rinsed very well to get rid of all the soap.
The Pandorea they are commonly known as trumpets of the East.
All species have a strong and penetrating root system therefore they should not be planted near buried pipelines.
The name of the genus comes from Pandora, name of the first woman created according to Greek mythology (from the Greek pan doron "All gift" because every god of Olympus had given her a gift) who opened a sealed vase donated by Zeus releasing all the evils that humanity did not yet know. The similarity is related to the fact that each pod contains many seeds that disperse into the air once opened.
