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 of the the Althea rosea it is advisable to locate it in a place where it is exposed to at least a few hours of direct sunlight.The Althea rosea is a plant which can be grown in the garden year round.
Feed Althea rosea
When we prepare the soil to welcome our annuals, in the apring or at the beginning of the summer, letís 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.
Care 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.
Irrigation Althea rosea
Letís water these plants only when the substratum is clearly dry using 2-3 glasses of water ; during this period of the year we should intervene every 1-2 weeks , or even less if the weather is rainy. As autumn comes these plants tend to perish, we can diminish the waterings, or even interrupt them.
Adversity 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.
Substrate Althea rosea
Letís grow these plants in a soft and dissolved, but well drained, soil.
