GENERAL CHARACTERISTICS

The genre Cane includes perennial herbaceous species native to the subtropical tropical zones of America and Asia. Despite being a very species-rich genusin cultivation only hybrids of Canna indicatesto whom he will refer in this cultivation sheet.

These are plants with tubers whose beauty are very large leaves up to 60 cm long and guinating at the base. The flowers are gathered in apical spikes whose color varies from red, to yellow, to salmon, depending on the hybrid.

CULTURAL TECHNIQUE

There Cane it is a plant that expresses all its beauty only when grown outdoors.Only some dwarf varieties that do not exceed 70 cm in height can also be successfully grown indoors. In any case, if reared at home, in the summer it was taken outdoors.

They are all plants that require good light and direct sun and a very well ventilated environment.

Being tuberous plants at the beginning of autumn, the leaves are cut and the stems are recovered from the ground to let them overwinter at about 10-12 ° C in a layer of peat kept just humid to prevent them from drying out. They will replant outdoors as soon as the danger of spring frosts is averted.

WATERING

During the whole period of active growth that goes from spring to autumn the lacanna should be watered generously. In fact, in its countries of origin, it grows in swamps and along waterways.

TYPE OF SOIL - REPOT

Repotting takes place every year in consideration of the fact that the tubers are planted every year, after the winter break. A good soil rich in organic substance is used with the addition of a little sand to make it softer.

FERTILIZATION

From spring and throughout the summer, administer it Cane with watering once a week a good liquid fertilizer in half doses as those indicated in the packages are always exaggerated.

It is advisable to use a fertilizer rich above all in phosphorus and potassium to stimulate the flowering.

PRUNING

There Cane not pruned. Only the parts that dry out or become damaged are eliminated to prevent them from becoming a vehicle for parasitic diseases.

FLOWERING

Flowering is summer. Eliminate the flowers that gradually wither to stimulate the emission of new ones.

MULTIPLICATION

The multiplication takes place by division of the tubers to be carried out at the beginning of spring, coinciding with the planting of the tubers so that each portion has at least one eye. The portions will be planted in a fertile soil and must be kept at a temperature of 18-20 ° C keeping the soil always well moist. The appearance of the first shoots will indicate that root has occurred. At that point, the young seedling is expected to become stronger and will be planted in the open ground in May, when the period of late frosts will be averted.

PARASITES AND DISEASES

Presence of small whitish animals on the plant

If you notice small white-yellowish-greenish mobile insects you are almost certainly in the presence of 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.

Remedies: 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.

Spots on the underside of the leaves

Spots on the underside of the leaves could mean that you are in presence of cochineal and in particular mealy cochineal. To be sure, it is advisable to use a magnifying glass and observe. Compare it with the photo on the side. Also if you try to remove them with a fingernail, they come off easily.

Remedies: use specific pesticides available from a good nurseryman.

Leaves that begin to turn yellow, appear mottled with yellow and brown

If the leaves begin to turn yellow and after these manifestations are crumpled, they take on an almost dusty appearance and most likely fall in the presence of an attack of red spider, a very annoying and harmful mite. Observing carefully you can also notice some thin cobwebs especially on the lower page of the leaves.

Remedies: increase the frequency of nebulizations to the foliage (the lack of humidity favors their proliferation) and possibly, only in the case of particularly serious infestations, use a specific insecticide. If the plant is not particularly large, you can also try cleaning the leaves to mechanically eliminate the parasite using a wet and soapy cotton ball. After that the plant was rinsed very well to get rid of all the soap.
