Annual plants are usually not grown during the cold period; as autumn arrives we can uproot them and save the seeds for the year after. For a balanced development, it is best to position the the Althea rosea in a place where it is exposed to at least a few hours of direct sunlight.The Althea rosea plant can be grown in the garden throughout the whole year. It doesn't fear cold weather and it bears very harsh minimum temperatures.
Fertilization Althea rosea
When we prepare the soil to welcome our annuals, in the apring or at the beginning of the summer, let’s add a good quantity of manure, or slow release granular fertilizer. To improve the flowering we can also give it specific fertilizations for flowering or green plants, mixed with the irrigating water, every 20-30 days.
Generalities Althea rosea
The development of these plants is columnar, they grow aiming high with a scarce lateral development. The Althea rosea is a year or two year long plant. Althea rosea isn't an evergreen; during the spring, summer, autumn, winter it assumes a redpink colouring; the adult species are medium in size and reach 2,4 m in height.
Watering Althea rosea
We suggest watering these plants only from time to time, but we must remember to wet the soil deeply using 2-3 glasses of water every 1-2 weeks . As autumn comes these plants tend to perish, we can diminish the waterings, or even interrupt them.
Treatments Althea rosea
The spring weather, with a high temperature swing between the day and night hours, and pretty frequent rains, can favour the development of fungus diseases, which should be treated pre-emptively with a systemic fungicide, to use before the gems grow excessively; at the end of the winter we also suggest a wide range insecticide to prevent the attack of aphids and cochineals. We should always remember to do these treatments when there aren't flowerings in the garden.
Soil Althea rosea
Let’s grow these plants in a soft and dissolved, but well drained, soil.
