Dahlia flower

How much and how to water

The dahlia flower is not a very demanding plant, as far as irrigation is concerned, especially if you give it the right attention. At the time of the planting it does not need much water, since the period, March, is rather humid. To favor the growth of the dahlia flower we can add fertilizer diluted in water, on average every ten days. During the hot periods, however, it should be watered with a certain consistency. We need to water only when the soil is dry and, since they require a lot of water, we must always try to maintain a humid environment, but not excessively wet. In general, the regularity of watering varies according to the environment in which the plant is placed, the period and the common sense of those who care for it. On average we can intervene twice a week.

How to grow it


The flower dahlia is a plant native to South America. In its natural state it grows in areas of volcanic origin, for this reason, to have excellent results, we must try to recreate that type of environment: a drained and permeable soil, a fairly sunny position and good fertilization. It is very important to keep the humidity level of the plant controlled and constant; in fact the dahlia flower comes from tropical climates. There are different types of flowers, and they differ in size, color and fans. They can be obtained vegetatively and by seed, and are suitable for planting in pots. The dahlia flower can be cut and used in compositions and to better keep the collected flower we must cut the stem with an oblique cut and then we must immerse the flower in warm water.

How and how much to fertilize


The dahlia flower is a plant that, in addition to a good amount of water, needs a lot of nourishment, for this reason we will add to the soil a good amount of organic soil conditioner, preferably mature manure, so as to make the soil more aerated and allow greater availability of minerals that increase the luxuriance of the plant and the beauty of its flowering. According to the indications that we will have from our seller, we must add some slow release granular fertilizer and, as needed, we add phosphorus and potassium (NPK 5-10-15) especially after winter and during growth. If necessary we can also add sulfur, or lime, or we can use other types of specific fertilizers, always following the useful advice given by the seller.

Dahlia flower: Exposure, diseases and pests


The dahlia flower is a type of plant that is quite exposed to diseases, insects and especially snails, so it needs a lot of attention. We must monitor it as it grows and, when it reaches 5-10 cm in height, we distribute an insecticide, pyrethrin, about every two weeks. It is very important to keep the area around the dahlia plant clean, as these plants compete with others for water, sunlight and other nutrients. Particular attention should be paid during the evening exposure, towards snails and insects. In the event that the dahlia flower should contract some type of contamination, the remedies to be able to eradicate this disease are: the use of insecticidal substances and the use of disinfectants.
