Exotic potted plants - fit through the winter

The Content Of The Article:

For cold-sensitive species such as Hibiscus, Schönmalve, ornamental banana and sky flower (Thunbergia grandiflora) ends the outdoor season, as soon as the temperatures fall below ten degrees. However, these candidates, who originally lived in the tropics, have another advantage: they tolerate heat even in winter. An excellent winter location, for example, is the moderately heated guest room. Even the living room is suitable if you can offer the plants a place directly at the bright window. From the radiator you should keep them away, because dry-warm air favors pest infestation.

Most exotic potted plants are evergreen species that keep their leaves even in winter. They need a lot of sunlight. Behind a pane of glass, however, the light is less intense than under the open sky - which is why the plants reduce their metabolism. This resting phase is supported by low temperatures in many plants. If the temperatures are too high, this will cause an imbalance, as the plants stimulate the metabolism while being slowed down by the lack of light. Ideal for most species are temperatures of five to ten degrees, as it provides, for example, a cool conservatory. Even bright, unheated basements, garages or staircases are suitable - if it is ensured that the thermometer does not fall below the zero-degree limit. Among the species that can handle cool zero to five degrees include myrtle, spice bark (cassia), star jasmine, loquat and cylinder cleaner.

Check container plant for pests

Check the overwintering guests regularly for pest infestation. Especially in winter quarters, the risk of infection is very high!

As a precaution, you should only clear pest-free plants to the winter quarters. Specimens that have just been visited by pests, you put separately first. At each nursing tour, check your charges for the first signs of pests and diseases.
In particular, examine the leaf undersides and branches, as these are popular hiding places. White flies are often a plague in warmer conservatories. Yellow boards, which you hang in the branches or put in the ground, help against them. Thrips and spider mites can spread rapidly in stagnant, dry air. Preventively, the plants should be sprayed with water more often, in case of infestation, pyrethrum-containing agents are recommended. Wool and scale lice can only be managed in the long term by consistent collection and oily preparations. Prevent fungal diseases by regularly removing fallen leaves and dead plant parts.
