Water the dahlia
The dahlia loves the sun and therefore the abundant supply of water. In summer, it is especially recommended to water the soil carefully to moisten the earth well, but without exaggerating. In fact an excessive humidity produces the rot of the bulbs. In autumn, however, when the rains begin, it is better to suspend watering. Then in the water it is good to pour some fertilizer in the vital period of the plant. The varieties of the dahlia are numerous and divided according to how the flower is made. So different colors and shapes characterize it. Among those that can be found in Italy there are flat-flowered dahlias with petals of varying length, others that resemble water lilies or the ball-shaped or pompon-shaped dahlia. But there are also some with fine and pointed petals or curved to form a cylinder.
Dahlia and its cultivation
Dahlia is grown by seed or by dividing the roots. In order to obtain new plants using the roots, they must be kept in boxes of sand and peat at a maximum temperature of 5 ° C until spring, after which they pass into a new box with moist and not so rich earth. To prune the dahlia it is advisable to check the plant well during flowering once every seven days and eliminate the wilted flowers and those parts that have become dry. This is a way to conserve the energies set aside by the dahlia and which she herself will use for the new bloom. About the latter, its period lasts for a long time, in fact it starts in July to end in the autumn. The plant will make its flowers bloom, admired and appreciated by all for their color and shades, with a rounded and graceful shape.
