Care Perennial cornflower
These plants are perennial herbs. The Perennial cornflower has a panel-like development, therefore it tends to widen very much. This plant in the summer assumes a purple colouring; it is small in size and can reach 50 cm high. It doesn't keep its leaves in the winter.

Temperatures Perennial cornflowerSole pieno
Let's grow the The Perennial cornflower in a luminous place, with direct sunlight. Let's grow the The Perennial cornflower outdoors; they can bear very harsh minimum temperatures, even when many degrees below zero.These plants shouldn't be grown in the garden during the cold period; in autumn the plants usually perish, and should be eradicated from the ground.

Irrigation Perennial cornflowerTenere asciutto
We suggest watering the The Perennial cornflower every 1-2 weeks with 2-3 glasses of water , which means when the soil has been dry for days; if the season should be very hot and arid we can intensify the quantity of irrigations, although we must avoid leaving the substratum soaked with water. As the cold weather arrives, in autumn, we can interrupt watering, and let the plants perish.

Adversity Perennial cornflower
As the day-time temperatures rise at the beginning of the spring, it is agreeable to practice a preventive treatment, with a wide-range insecticide, which should be applied when there aren’t flowerings in the garden. Before the buds become too large, it is advisable to also treat them with a wide-range fungicide, to prevent the development of fungal diseases which spread easily when there is an elevated environmental moisture.
