Dahlia


Water the dahlia


Dahlia loves the sun and therefore abundant water intake. In summer it is especially advised to water the soil with care to moisten the soil well, but do not overdo it. In fact, excessive humidity produces the rot of the bulbs. In autumn, when the rains begin, it is better to stop watering. Then in the water it is good to pour fertilizer in the vital period of the plant. The varieties of the dahlia are numerous and divided according to how the flower is made. Thus, different colors and shapes characterize it. Among those that can be found in Italy there are flat-flowered dahlias with petals of various lengths, others that resemble water lilies or ball-shaped or pompom-shaped dahlias. But there are also some with fine and pointed petals or curved to form a cylinder.

Dahlia and its cultivation



Dahlia is cultivated by seed or by dividing the roots. In order to get new plants using the roots, they must be kept in sand and peat boxes at a maximum temperature of 5 ° C until spring, then they are moved to a new box with moist and not so rich soil. To prune the dahlia it is advisable to check the plant well during flowering once every seven days and eliminate the withered flowers and those parts that have become dry. This is a way to conserve the energy set aside by the dahlia and which it will use for the new bloom. About the latter, its period lasts for a long time, in fact it begins in July to end in autumn. The plant will make its flowers bloom, admired and appreciated by everyone for its color and nuances, with a round and graceful shape.

How to fertilize dahlia



The bulb of the dahlia wants a standard soil, but drained and fertilized. The most interesting results are obtained with a special soil for demanding plants that can be found in any qualified store. However, it is good to add organic fertilizer to help the dahlia during growth. If, on the other hand, the plant is grown in pots, it is advisable to place a layer of sand on the bottom to make the soil more draining. The bulbs use all the nutrients they have available to flower at their best, so the best soil will be rich in organic substances and must be fertilized regularly every fifteen days. Maybe use the fertilizer until the leaves appear; later, that is during flowering, no other fertilizer should be given as the plant will already have enough energy to make the garden or the balcony of the house a blaze of beauty and color.

Dahlia: Exposure and diseases of the dahlia



The dahlia has always been used to the heat and the sun and therefore bears well the temperatures that rise even over 30 °, but hates the cold. Here then are the dahlia plants all exposed to the sun in the area of ​​the hottest garden, full of light and where a slight breeze blows. In winter, on the other hand, the dahlia is to be kept sheltered from frost and very low temperatures that could compromise the next flowering. If you have dahlias in the vase on the balcony it is much better to place them in a sheltered place during the cold season. However this beautiful plant may unfortunately be attacked by moths and aphids that ruin the stems. It is also subject to white disease and preferred by certain parasites that use it for their larvae. So, when you put the seedlings in the ground it is good to distance them a little to get more air and light vegetation, avoiding the stagnations that create rot at the roots. In fact the parasites live well in the wet areas unlike the plants themselves. In the end, it is recommended during the flowering of the pesticides against molds and fungi.
