The Coneflower should be grown outdoors; it can bear very harsh temperatures without any problems, even many degrees below zero. These plants lose the aerial part during the coldest months of the year. As spring begins, stems and leaves quickly start to reproduce.The Coneflower should be grown in a bright place, with direct sunlight.
The Coneflower is a perennial herb plant. The Coneflower is medium in size and 75 cm in height; in the summer it assumes a yellow colouring. These plants aren't evergreens, which means they lose their leaves some months during the year. These plants give origin to a brush with a rounded form.
We suggest adding to the irrigation water, in the spring, every 20-25 days, a specific fertilizer for flowering plants. We can also mix to the soil near the plants a granular slow release fertilizer, which has a 3-4 month action.
During this period of the year the The Coneflower needs regular watering, which should be done letting the soil dry between one watering and the other; let’s irrigate every 1-2 weeks with about 2-3 glasses of water . Perennial plants are subject to some months of vegetational rest. During these months it isn't necessary to water them.
Generally during this time of year we suggest a pre-emptive treatment with wide range insecticide and with a systemic fungicide, to prevent the attack from part of the aphids and the development of fungus diseases, often favoured by a mild and damp climate.
These plants need a scarcely drained soil, which can remain slightly damp.
When wanted we can grow these plants in a vase. The indications given in this article are related to a medium size plant.
